Public Transportation uses more Renewable Energy

Public Transportation uses more Renewable Energy

By John Addison (9/29/09). More Americans ride on public transit than any time in the past 50 years as more live in cities and most watch their transportation costs. Remarkably, transit operators are moving more people, yet reducing our dependency on oil and generating less carbon emissions. Increased use of solar, other renewables, vehicle electrification, and low-carbon fuels are all part of solution.
New Jersey Transit is preparing for a future where parked cars can be charged with sunlight while people use public transportation. New Jersey Transit is installing 402 kW solar canopies on the rooftops of two large parking garages at the Trenton Amtrak Transit center.
These parking structures are also equipped with 110v charging stations for electric vehicles and plug-in hybrids. Participating in the opening ceremony was the Mid-Atlantic Grid Interactive Cars (MAGIC) consortium, which includes the University of Delaware, Pepco Holdings, PJM Interconnect, Comverge, AC Propulsion, and the Atlantic County Utilities Authority, created to further develop, test, and demonstrate vehicle-to-grid technology.
A few years ago, Los Angeles Metro invested $5 million to install 2MW of solar power as part of a three-year plan to install solar panels on every Metro Bus and Rail facility within its Los Angeles County service area. For example, the solar panels installed on Metro Bus Division 18’s maintenance building rooftop and shading parking structures consist of about 1,600 solar panels that generate 417 kilowatts of electricity, enough power pay for itself in 10 to 11 years.Now LA Metro will receive $4,466,000 to make its rail system more energy efficient. Red Line Westlake Rail Wayside Energy Storage System: Install wayside energy storage substation (WESS) at Westlake passenger station is at-grade level on the high-speed heavy rail subway Red Line. The nearby traction power substation will be switched off when the WESS is operating. The WESS flywheel technology captures regenerative braking energy when trains slow or stop and transfer back to same train or another train when it starts or accelerates, reducing energy demand and peak power requirements.
This month, the federal administration announced $100 million in Economic Recovery Act funding for 43 transit agencies that are pursuing cutting-edge renewable energy and efficiency technologies to help reduce global warming, lessen America’s dependence on oil, and create green jobs. The 43 winning proposals were submitted by transit agencies from across the country as part of a nationwide competition for $100 million in American Recovery and Reinvestment Act of 2009 (ARRA) funds. Selection criteria included a project’s ability to reduce energy consumption and greenhouse gas emissions and also to provide a return on the investment. The Federal Transit Administration reviewed more than $2 billion in applications for these funds.
AC Transit in Oakland, California, is awarded $6,400,000 to increase photovoltaic capacity to generate “green” hydrogen: Install multiple PV modules at its Central Maintenance Facility in Hayward. Combined with AC Transit’s already-installed solar capacity, this solar installation will produce the renewable electricity equivalent to what will be required to produce 180 kg/day of “green” hydrogen for 12 buses carrying up to 5,000 riders daily, for the current 3 zero-emission buses that carry about 1,000 riders daily.
VIA Metropolitan Transit, San Antonio, Texas, was awarded $5,000,000 to replace conventional diesel transit buses with 35-ft composite body electric transit buses. The project includes quick-charging stations at this terminal layover in route to recharge bus batteries. Grid sourced electrical energy used to recharge the bus batteries will be augmented with solar energy collected with panels procured and installed under this project.
The nation is becoming less dependent on oil as record numbers escape solo driving in gridlock and increasingly use public transit. Electrification of light-rail and buses coupled with renewable energy makes this transportation greener.

When David Roberts was growing up near the oilfields of West Texas in the early 1960s, it never got dark. Back then, oilfields were lit 24/7 by the gas flares used to burn off natural gas, a byproduct of oil drilling. The flares released massive amounts of CO2, and over time, oil companies halted that harmful practice in the U.S. But gas flares remain the norm in the developing world—and today Roberts oversees a team at Marathon Oil that's trying to end the practice. In 2007, Marathon opened a $1.5 billion liquid-natural-gas plant in Equatorial Guinea to capture the natural gas that once went up in smoke. The plant is one factor that helped Marathon, No. 100 in NEWSWEEK's Green Rankings, cut its CO2 emissions by 40 percent between 2004 and 2008—and the plant earns a profit.

It's a small example of how the economic case for going green is becoming more compelling. Economists view environmental damage as a classic "externality"—a cost that impacts society but isn't imposed on producers or consumers. But with scientific consensus that carbon emissions threaten our climate, there's growing political will to curb them, particularly with the global powers set to meet in Copenhagen in December. The Obama administration is pushing for a cap-and-trade system that would turn companies' emissions into a bottom-line cost. Smart companies are working to better understand—and cut—those emissions ahead of new regulations.
The inaugural NEWSWEEK Green Rankings recognizes those efforts. For more than a year, the magazine worked with leading environmental researchers KLD Research & Analytics, Trucost, and CorporateRegister.com to rank the 500 largest U.S. companies based on their actual environmental performance, policies, and reputation.
Ranking companies based on sustainability is a huge challenge. That's largely because comparing environmental performance across industries is a bit like analyzing whether Tiger Woods or LeBron James is the world's greatest athlete—there's an inevitable apples-and-oranges element. Some industries are far dirtier than others: a typical financial-services company exacts a smaller environmental toll than even the best-run utility or mining company. Also, many corporations are secretive about key environmental data, if they track the numbers at all. Even among companies that do report green data, there's no uniform standard, so their numbers often aren't comparable.

Despite those obstacles, we worked hard to design a ranking system that makes sense. More than half of companies' overall Green Scores are based on their environmental policies and reputation, industry-neutral metrics that help even the playing field for companies in carbon-intensive businesses. To overcome limited corporate emissions numbers, NEWSWEEK used data from Trucost, which has created a widely acclaimed system for estimating emissions of companies that fail to provide them. (Note, however, that among our Top 100 best-performing companies, 70 voluntarily disclosed the data.) Over time, we hope NEWSWEEK's rankings will become more precise as more companies begin to report their numbers. "One of the purposes of this is to improve the transparency of corporations…and encourage them to provide an even higher level of disclosure," says Thomas Kuh, KLD's managing director.
Many of the companies that finished in our Top 100 are recognized leaders in sustainability. Intel, No. 4 in NEWSWEEK's ranking, recently launched an initiative in which every employee's annual bonus is tied, in part, to how well the company does in meeting sustainability goals. Wal-Mart, No. 59, recently announced plans to create a Sustainability Index that will help consumers better understand which products sold in its stores are greener than others.
Rankings inevitably provoke controversy—and we welcome that. Our hope is to open a conversation on measuring environmental performance—an essential first step toward improving it. The NEWSWEEK Green Rankings for 2009 on the pages ahead provide a snapshot of companies poised at this most important starting line.

DOE Solar Decathalon on National Mall

October 9-13 and 15-18, 2009

Plan to attend the Solar Decathalon on the national mall in Washington, DC.

About Solar Decathlon
For three weeks in October 2009, the U.S. Department of Energy will host the Solar Decathlon—a competition in which 20 teams of college and university students compete to design, build, and operate the most attractive, effective, and energy-efficient solar-powered house. The Solar Decathlon is also an event to which the public is invited to observe the powerful combination of solar energy, energy efficiency, and the best in home design.

Exact dates of the 2009 event are:
Oct. 1—Teams arrive at the National Mall and begin assembly of their houses-->
Oct. 8-16—Teams compete in 10 contests
Oct. 9-13—Houses are open to the public
Oct. 15-18—Houses are open to the public
Oct. 19-21—Teams disassemble their houses.

The Solar Decathlon houses will be open for public tours 11 a.m.­–3 p.m. Monday–Friday and 10 a.m.–5 p.m. Saturdays and Sundays. Please note that all homes will be closed Wed., Oct. 14.
The Solar Decathlon consists of three major phases:
Building: This is where most of the work—and the learning—happens. In addition to designing houses that use innovative, high-tech elements in ingenious ways, students have to raise funds, communicate team activities, collect supplies, and work with contractors. Although the Solar Decathlon competition receives the most attention, it's the hard work that students put in during the building phase that makes or breaks a team.
Moving to the Solar Village: When it's time for the Solar Decathlon, the teams transport their houses to the National Mall in Washington, D.C., and rebuild them on site.
Competing: During the competition itself, the teams receive points for their performance in 10 contests and open their homes to the public.
Purpose
The Solar Decathlon brings attention to one of the biggest challenges we face—an ever-increasing need for energy. As an internationally recognized event, it offers powerful solutions—using energy more efficiently and using energy from renewable sources.
The Solar Decathlon has several goals:
To educate the student participants—the "Decathletes"—about the benefits of energy efficiency, renewable energy and green building technologies. As the next generation of engineers, builders, and communicators, the Decathletes will be able to use this knowledge in their studies and their future careers.
To raise awareness among the general public about renewable energy and energy efficiency, and how solar energy technologies can reduce energy usage.
To help solar energy technologies enter the marketplace faster. This competition encourages the research and development of energy efficiency and energy production technologies.
To foster collaboration among students from different academic disciplines—including engineering and architecture students, who rarely work together until they enter the workplace.
To promote an integrated or "whole building design" approach to new construction. This approach differs from the traditional design/build process because the design team considers the interactions of all building components and systems to create a more comfortable building, save energy, and reduce environmental impact.
To demonstrate to the public the potential of Zero Energy Homes, which produce as much energy from renewable sources, such as the sun and wind, as they consume. Even though the home might be connected to a utility grid, it has net zero energy consumption from the utility provider.

Major Newspapers On The Pickens Plan

Break the Curse of Oil Addiction – Austin American-Statesman – 9/16/09By The Editorial Board “We should not let desire to argue over the messenger and his message rob us of the necessity to shed our oil dependence. Rigs that burn natural gas may not be the whole solution, but that certainly is a move in the right direction.” *** T. Boone Pickens Has a Plan to Reduce our Dependency on Foreign Oil – Standard-Examiner (UT) – 8/30/09By Rick Stewart “Well, as you may have heard here, he has a plan. And the backbone of that plan is natural gas…and the best part of all this natural-gas, clean-energy talk for red state, Republican Utahans? You don't have to be a tree-hugger to support it.” *** Pickens: A Man with a Plan – Daily Herald (UT) – 8/25/09 “So why haven't we (cut our gasoline dependence)? It's all a matter of leadership...He's right about that...It's time to kiss the naysayers goodbye and watch our economy take off.” *** Pickens Has Changed Energy Debate – The Wichita Eagle – 7/30/09 “A year into his multimedia campaign, Pickens has more than 1 million followers and the confidence to say that the American people want his plan...give the 81-year-old oilman credit for waking up Americans and their leaders to the urgent need to import less oil and make the most of domestic energy sources. When Pickens speaks, people not only listen but also act.” *** One Year Later: Pickens Plan Impacts Energy Debate – Fort Worth Business Press – 7/20/09By Will Brackett “With his continued push, Pickens will help to transform our nation’s energy usage away from foreign oil and more toward cleaner-burning, affordable and abundant natural gas – which best of all, is ours. We support Pickens in his efforts and wish him the best of success in his endeavor to bring us to a day when our nation can achieve a realistic degree of energy independence.” ***CabinWindow: Pickens Man with a Plan – Log Cabin Democrat – 6/11/09 “Pickens has a sensible notion, and we hope all of America hears his ideas, but at the end of the day, change will only come when our elected leaders say with a united voice that our future won't hinge on foreign oil.” *** Join Army Working for Energy Freedom – Springfield News-Leader (MO) – 5/13/09By Wade Palmer “The Pickens Plan is not the only solution, but it's an important piece of the machinery. Still less than one year old, The Pickens Plan boasts an army of nearly 4 million activists and the larger this army grows, the more they can influence our nation's energy policy. The men and women in Congress listen only when the voices are very loud . Real progress toward energy independence will take years (decades) so we cannot afford to wait ... now is the time to act.”

GE To Manufacture Offshore Wind Turbines

GE To Manufacture Offshore Wind Turbines

September 18th, 2009

GE, the US industrial group, is promoting and showing confidence in offshore wind technology by buying ScanWind, which makes direct-drive turbine components. This move will help in generating thousands of new jobs in the field of designing and manufacturing turbines. This move will affirm the confidence of investors in the fledgling offshore wind industry, which has been weighed down by concerns about costs and reliability. GE is moving ahead with establishing turbine manufacturing facilities to serve the European markets at first. They have to make up their mind about the size of the investment and location.
GE is already a force to reckon with in onshore wind power: it sells about fifty percent of the new turbines being installed in the US. GE’s global share amounts to about 20 per cent. GE was not an enthusiastic participant in the offshore business till now. They were running the show for a small demonstration facility in Ireland. Their executives were quite apprehensive about the economics of offshore generation. But we know that none of the business ideas are permanent and they get approved or disapproved according to the external environment of a country or world. When we live in a country which is densely populated with coastal reasons, we know that there is not enough space for on-shore wind projects. But we have to cater to the clean and green energy demands of a nation. So off-shore wind turbines are the one of the best answers for such countries. Off-shore wind speeds are generally higher and wind blows at a steadier pace. We can use larger turbines to harness more wind energy – larger turbines that can be easily transported via marine route. If offshore turbines are directly connected to the power grids then there is no need for overland high-voltage transmission lines in heavily populated areas. Therefore GE executives are taking advantage of the external challenges of the European continent to provide clean and green energy. The EU has a bigger target of deriving 20% of its overall energy from renewable resources by 2020 and this requires huge expansion of offshore wind production.
Vic Abate, GE’s vice-president for renewable energy, said: “The company now believed the subsidies in place for offshore wind, such as Britain’s Renewables Obligation, were robust enough to encourage large-scale investment. Offshore wind is more expensive, so without the subsidies and other supports the economics can’t stand up.” Now governments too are creating the right kind of environment to invest in off-shore wind technology. Industrial houses are quick to grab the incentives offered by the governments.
Of course the viability of offshore wind production hinges a lot upon reliability because the turbines will be maintainable only by boats, or may be ships.
GE is expected to invest hundreds of millions of dollars setting up the business, and at the same time hold out the prospect of thousands of jobs being created. These jobs will create both directly employment such as in designing and manufacturing operations, and indirectly in activities such as installation and support services.
GE is also teaming up with a company with offshore oil and gas expertise, so that they can gain an insight into the sitting structures in challenging marine environments.
Mr. Abate said GE is still in the process of exploring its new offshore wind facilities location. He stated it was likely to be where the company was offered the best partnerships by governments and local businesses.

12 million Homes Powered by German Off-Shore Wind

Germany’s position as the world wind leader was consolidated today with an announcement of 40 offshore wind farms to be built in German waters more than 12 miles off the coast.
The goal is to get a total of 25,000 megawatts just from ocean-sited wind power by 2030. This would provide the first half of that; from a 12,000 MW wind farm.
Germany is only just starting to dip its toes into off-shore wind production. It signed its first offshore wind project of just 15 megawatts a few months ago with the Alpha Ventus project that was co-financed by German energy giants Vattenfall, E.on and EWE and subsidized by the German government.

The same financing consortium of the three energy giants; Vattenfall, E.on and EWE is financing the 40 farms; working closely with the government. Germany has set aside about 100 square kilometres for offshore wind projects; in order to advance renewable power.
The nation already leads the world in wind power with 22,000 Megawatts-worth, on-shore till now. The similarly sized would-be “nation” of Texas, in America, comes a distant next with 8,000 megawatts of wind power.
Thirty of these forty new wind farms would be in the North Sea with ten in the Baltic Sea. Twenty-two have already received government approval.
The 40 farms would supply 12,000 megawatts of power. Enough to supply 12 million households, which sounds great, till you realize that there are well over 82 million people in Germany - comprising perhaps 30 million households. Currently Germany provides only 3% of its own hefty power needs from its current 22,000 megawatts of land-based wind.
These 12,000 additional megawatts will get Germany well on its way to meeting its overall renewable energy goals under the Kyoto accords set decades ago and modified over time under European Cap and Trade legislation. To meet those goals it must get 30% and possibly now 36% of its energy from renewable sources by 2020 with wind energy providing probably half of that.

Google To Develop Improved Solar Technology

Google Plans To Develop More Efficient and Cost-Effective Solar Thermal Technology

As if Google isn’t already doing enough for the world of technology, they’re actually joining the solar technology movement in order to help increase the progress, which they believe has been disappointing to date. Their goal is to use mirror technology for solar energy that will be cheaper and therefore more accessible to the masses, so cost isn’t such a contributing factor to why many are unable to make their homes a little bit greener.
» See also: 12 Million Homes Powered By German Off-Shore Wind
» Get CleanTechnica by RSS or sign up by email.
The technology available on the market today a 250-MW solar thermal installation costs $0.12 to $0.15 a KWh and Google’s goal is to reduce costs by at least half, but ideally by 66% to 75% so costs come in around $0.05 or less. In order to reach this goal of lowering costs and increasing efficiency, Google is currently testing different materials to find a better solution, and plans to unveil a prototype model within the next few months, and part of that evaluation process will include ensuring that the material used for a solar thermal installation will be able to withstand the tests of time.
This isn’t the first time we’ve heard that Google is hoping to make green technology a little more efficient and accessible, and as a leader in technology, they are trend-setting their way to cleaner and greener tech!

12 Year Old Invents New Type Of Solar Cell

Now here’s a story that makes me feel profoundly unaccomplished: a 12 year old boy in Beaverton, Oregon recently developed a new type of 3D solar cell that makes other solar cells look inefficient by comparison.

Solar Cells Made With Silicon Ink

JA Solar, one of the big players in the solar industry, is working with Innovalight to commercialize the latter's method for making silicon-ink-based, high-efficiency solar cells, the companies said this week.
Innovalight first got noticed in 2007 for perfecting a process in which it could essentially ink-jet-manufacture solar cells using a proprietary silicon ink it had developed. The solar cells are created by pouring an ink solution incorporated with silicon nanoparticles and then decanting the excess liquid to leave behind a crystalline silicon structure.

This is Innovalight's crystalline silicon solar cell.(Credit: Innovalight)
At the time of the 2007 announcement, Sunnyvale, Calif.-based Innovalight claimed its method not only resulted in solar cells that were cheaper to produce by as much as half, but that the crystalline structure resulting from the process made its cells more efficient at converting electricity.
Those claims now appear to be validated.
On Tuesday, Innovalight announced that an independent study of its method by the U.S. Department of Energy's National Renewable Energy Laboratory and the Fraunhofer Institute for Solar Energy Systems in Germany confirmed that its silicon ink-based cells "demonstrated a record 18 percent conversion of efficiency."
Shanghai, China-based JA Solar said the process will lower its production cost for this type of solar cell.
"Innovalight's silicon ink in conjunction with JA Solar's leadership in high-volume solar cell manufacturing with demonstrated yield, conversion efficiency, and low production costs, provides a very promising solution to enhance the conversion efficiency of solar cells utilizing our existing solar cell manufacturing lines," Qingtang Jiang, JA Solar's chief technology officer, said in a statement Tuesday.
JA Solar plans to further develop the process at its research and development plant in Yangzhou, a city on China's coast about 630 miles south of Beijing.

Five months ago, county administrators and board members grudgingly approved a 2009 budget that included across-the-board department cuts as well as an early buyout program to close a $3 million operations gap in the county budget.Thursday night, board members were told that the budget shortfall might be close to double that by the end of the year. Winnebago County Administrator Steve Chapman said the county’s first quarter results were in — the county runs on an October to September fiscal year — and extrapolating the early numbers through the entire year would leave the county with a $5.6 million shortfall by the end of the year.Winnebago County Board Chairman Scott Christiansen said expenses have been less than budgeted so far this year, but the county really got hurt on the revenue side with everything from tax receipts to fees and interest payments down anywhere from 1.5 percent to 48 percent of where budget planners thought they would be. “I was shocked when we started getting these in,” Christiansen said. “You know, the wheels really started falling off (of the economy) in October which is right after we approved our budget. ... Knowing what was going on in the economy, I wasn’t surprised we took a hit, but I was shocked at how far it had fallen.”Christiansen said county department heads have already begun meeting on what looks to be another tight year and he said he’ll likely come to the County Board with an amended 2009 budget for their consideration. In other business, the board approved a development agreement with a Chinese solar-panel manufacturing company that is being courted by city, county and airport officials. Wanxiang Group has been eyeing two pieces of property by the airport — one for a manufacturing plant and another for a solar farm — but it wanted some assurances from local governments before it would locate here. The county’s stake in the agreement was to promise to buy $200,000 worth of solar panels over the next two years. “Following the dire news of a $5.6 million budget shortfall and 12 percent unemployment, I have some good news,” said John Ekberg, who chairs the board’s economic development committee. Ekberg said the project would bring 282 construction jobs in the immediate future when construction on the facility begins this summer and has the potential of bringing up to 200 full-time manufacturing jobs to the area in the “next five to 10 years.”Staff writer Mike Wiser can be reached at mwiser@rrstar.com or 815-987-1410.

Winnebago County Chinese Solar Panels

Winnebago County ponders how to pay for solar panels

A committee of Winnebago County Board members committed the county to buying $200,000 worth of solar panels from a Chinese manufacturer to help convince the company to set up an operation here.The Wanxiang America Corp. has been working with the city, county and the airport authority to come to a deal that has the potential of bringing 60 manufacturing jobs immediately and more than 200 in the future to the area.Although they ultimately approved the deal unanimously, board members had about an hour’s worth of questions for Rob Lamb, industrial development manager for the city of Rockford, who was taking questions about the proposal. Lamb said the county’s portion of the deal was pretty straightforward, in that the county would be committing to buy $200,000 worth of solar panels manufactured at Wanxiang’s eventual Winnebago County operation site over the next two years.The cost of the panels does not include installation of them on county buildings, which Lamb estimated would be $200,000 more. But he said the county also had the option to have the company set up the panels at a proposed solar farm near the Chicago Rockford International Airport where the county would then get into the power-selling business.“I think this is the right thing for this county and this economy,” said board member Frank Gambino. “But I have to ask, how are we going to pay $200,000 when we’re already in the red?”Winnebago County Board Chairman Scott Christiansen, who sat in on the meeting and indicated his support for the deal, said staff was still figuring out where the money could come from.He said it’s possible some of it could be paid for from grant money available through the federal stimulus package recently signed by President Barack Obama. “So we’re pretty sure that this can be paid for by the stimulus?” asked board member John Eckberg.“Whoa, whoa. Way too heavy with the language there,” Christiansen said. “It’s a possibility. That’s all.”Christiansen said the Winnebago County Justice Center and the MetroCentre could lend themselves quite readily for solar-panel installation, but that, and other proposals, would have to be studied in greater detail. “We really have a small part of this,” said board member Rick Pollack as he leafed through the pages of the agreement.“Looking at this, if I was a City Council member, I would have been sweating bullets.”Earlier this week, the Rockford City Council approved a deal with the company that gave Wanxiang 10 acres of land, more than $1 million in tax incentives and committed the city to buy at least $200,000 worth of solar panels for itself among other incentives.The deal is scheduled to go to the full County Board next week.Staff writer Mike Wiser can be reached at mwiser@rrstar.com or 815-987-1410.

Chinese Solar Panel Production Deal

Solar-panel production deal moving forward

A pending deal to bring a Chinese solar-panel manufacturer here could add 240 well-paying jobs, help nearby businesses go green for less money and put Rockford on the map for future such developments.The cost? More than $1 million in tax breaks, 10 acres of free land and commitments by city and county officials to buy hundreds of thousands of dollars in solar panels.City officials who are negotiating the deal with Wanxiang Group say it’s more than worth it.“They’re just a huge, huge corporation, so obviously we want them to be happy here, comfortable here and welcome here,” said Rob Lamb, the city’s industrial development manager. “They also were impressed by Rockford in that we didn’t look at this as just a deal. We look at this as the start of a relationship that would continue over a long period of time.”The Rockford City Council’s planning and development committee recommended approval of the deal tonight. It’ll go to City Council for approval next week. Winnebago County and Greater Rockford Airport Authority officials also need to approve their parts in the deal.If approved, the photovoltaic solar-panel facility would be at the city’s Logistics Park near the airport. Wanxiang is planning four phases totaling 160,000 square feet. Lamb said each phase would include about 60 jobs, paying $40,000 to $70,000 a year plus benefits. The company hopes to fill most positions locally.Construction on phase one would start by July, with the facility up to full production within 18 months of starting. Future phases would roll out according to demand for the panels.Wanxiang would invest $4 to $6 million in each phase.The company would get at least $1.2 million in tax increment financing money generated from the project over the next 18 years for the first phase. Future phases could guarantee Wanxiang more TIF money. The company also would get other state tax benefits by the River Edge Redevelopment Zone.Besides the 10 acres it’s getting — worth about $650,000 — Wanxiang would have an option on an additional 10 acres. That land could be used for additional expansion, for a Wanxiang sister company or for another company attracted here by Wanxiang.In the deal, city officials would commit to buying about $200,000 worth of Wanxiang solar panels to power some water pumping stations, while county officials would commit to $200,000 worth for its justice center. The airport would donate 100 to 200 acres for a solar farm operated by Wanxiang.The city also would pay half the cost of acquisition and installation of solar panels by companies in the surrounding Global Trade Park in the first five years of the deal, also using TIF dollars. For the following 10 years, the city would pay half the cost of acquisition only.“It helps these other companies diminish their electric loads, thus saving money,” Lamb said. “It helps the city and the community to pursue going green.”Wanxiang is China’s second-largest privately held company, with revenues in the billions of dollars annually. Its Wanxiang America subsidiary had $1 billion in sales last year.Last summer, Wanxiang and local officials signed an agreement to work on the deal, and have been ironing out specifics since. The company considered communities throughout the Midwest, and Rockford area officials feel by winning this deal they also attract other companies looking to invest in the United States. They’re particularly excited about alternative energy as a growth industry for the region, replacing well-paying manufacturing jobs that have been lost.“Wanxiang in China produces electric cars, electric buses, all kinds of things which they have not brought to the U.S. as of yet,” Lamb said. “There are other energy-related opportunities that fall into the realm of manufacturing, which is something Rockford excels at.”Staff writer Thomas V.

Maryland College 20-acre Solar Panel Project

Monday, August 10, 2009 at 4:17:08 PM - by Nate Lew
Maryland college plans 20-acre solar panel projectA historically black college in Maryland made news this week with its announcement that it will meet a sizeable portion of its energy needs with a new photovoltaic project. This week, the University of Maryland Eastern Shore announced it will build a solar farm on 20 acres of its campus land. The project will be financed, developed and maintained by SunEdison under a solar power service agreement. According to the university, the 2.1 megawatt system will be the largest solar plant in Maryland and will allow the university access to stable energy prices in the coming years. Construction is set to begin this fall and should be completed by the end of the year. "This program can be a model for other universities. We are excited that we can be a part of the energy future that Maryland puts forth in its plan for 1,500 megawatts of solar generation capacity by 2022," said Brian Jacolik of SunEdison. The university also noted that the terms of the project require no up-front investment on its part.

Home solar prices falling, even as rebates shrink

By Brandon Bailey

Updated: 09/15/2009 03:06:32 AM PDT

Joseph Levine has just had 106 solar panels installed on the two-level... ( KAREN T. BORCHERS )"," Left to right: Felipe Saldana, Dave Bischoff and Nick Buckman from Akeena Solar... ( Gary Reyes )

Even as a state rebate is shrinking, the price of residential solar power is dropping, thanks to lower installation costs and a glut in the supply of key components.
That's putting it in reach of more people and prompting solar advocates to say the day is coming when rebates and tax credits won't be needed to spur the growth of the renewable energy industry.
The cost of a typical 4,000-watt home solar system has dropped as much as 10 percent in the past year — falling below $20,000 in the Bay Area, after factoring in the California rebate and a federal tax credit that increased this year. Installers say a homeowner can recover the upfront costs of a solar system through lower utility bills in less than 10 years.
"The net economics of all this is getting better," said Barry Cinnamon, CEO of Los Gatos-based Akeena Solar, which sells residential and commercial systems. "We foresee a time, a few years from now, where we won't even need the state incentives."
One major subsidy is already starting to decline. The flood of applications for installation rebates under the California Solar Initiative is triggering a reduction this month in the size of rebates available from Pacific Gas & Electric, which administers the program in most of the Bay Area.
The $2.2 billion program, funded by utility ratepayers, was designed to provide bigger financial incentives at first, to jump-start consumer interest. As more people install solar

systems, the dollar amount of rebates decreases in incremental steps. For PG&E customers, the rebate for a 4,000-watt system will drop from around $6,200 to about $4,400.
On the other hand, the federal stimulus bill enacted in February removed a $2,000 cap on a 30 percent federal tax credit for home solar panels, allowing many homeowners to recoup several thousand dollars of their costs.
Even without those subsidies, experts say, changes in the global market are driving costs down.
"There's been a rather dramatic decline in the last six months," said Adam Browning, who runs a nonprofit advocacy group called the Vote Solar Initiative. He said he expects the trend to continue.
After several years of lagging behind demand, silicon refiners have ramped up production and solar-panel makers have increased their manufacturing capacity, particularly in China. Those factories came on line last year, just as a worldwide recession knocked down corporate spending for commercial solar installations.
As a result, the wholesale price of high-end solar panels has fallen by 50 percent, to about $2.40 a watt, according to analyst Nathaniel Bullard at the research firm New Energy Finance. Since Chinese manufacturers can make panels for close to $2 a watt, he said, prices are likely to fall further.
Panel prices are only about a third of the cost for installing a system. Labor costs are as much or more of a factor, said Curtis Seymour, a regulatory analyst at the California Public Utilities Commission.
The commission, which oversees the state subsidy program, has worked with solar contractors to devise more efficient installation procedures. Manufacturers and contractors have also come up with new hardware designs that take less time — and therefore cost less — to install.
One study found labor costs for installing solar panels have dropped 25 percent in the past two years, Browning said.
On average, a home solar power system cost about $8 a watt last year in California, according to researchers at the Lawrence Berkeley National Laboratory. That figure has dropped about 50 cents a watt in the past year, according to Vote Solar's analysis of state statistics. Cinnamon said he believes it will fall to $7.25 a watt this year.
"When we looked at it three years ago, the cost didn't make any sense for us. But compared to then, it's come down about 30 percent," said homeowner Susan Hollingshead, who recently signed a contract with Sungevity, a Berkeley company, to install a solar panel system for her four-bedroom house in Walnut Creek.
All told, PG&E has approved rebates for more than 11,400 residential solar installations since the program began in January 2007. Municipal utilities in Palo Alto and Santa Clara have separate programs for their customers.
Citing previous experience, Seymour at the utilities commission said the lower rebates may put a temporary crimp in applications, but consumer interest should rebound again.
Some people see the rebate step-down as bad news, he added, "but to us, it's a sign the program is working."

Treasury, Energy announce $500 m in alternative energy awards

Treasury, Energy announce $500 m in alternative energy awards

The U.S. Department of the Treasury and the U.S. Department of Energy today announced the award of $502 million in cash assistance for energy production companies. Treasury Secretary Timothy F. Geithner in a written statement expressed optimism that the awards will generate clean energy initiatives in urban and rural areas of the United States.
The award is part of a $3 billion program authorized by the American Recovery and Reinvestment Act. It provides direct cash payments to energy producers and developers as opposed to tax credits. The Obama administration expects that this round of funding will generate 2,000 jobs in the energy field.

Sunrise for solar heat power







Sunrise for solar heat power
Four technologies aim to use heat from the sun to make electricity. But which one has the edge?



Nearly a century ago, American engineer Frank Shuman erected five immense, trough-shaped mirrors in Meadi, Egypt. The parabolic reflectors directed sunlight onto a tube suspended above their 200-foot lengths. Water inside the tubes boiled and created steam. The steam powered a 65-horsepower engine, which pumped 6,000 gallons of water per minute from the Nile River to nearby cotton fields. It was the world’s first concentrated solar power (CSP) plant.
CSP entails focusing the sun’s rays with a reflective surface and putting that energy to work. These days, the heat usually goes to generating electricity. But the principle is quite old.
The ancient Chinese used concave mirrors to start fires, and, according to legend, the Greek mathematician and scientist Archimedes once used mirrors, perhaps of polished bronze, to ignite and burn an invading Roman fleet.
Shuman was addressing a concern of his time: Fossil fuels, particularly coal, powered the Industrial Revolution – the trains and mills, among other things, that radically changed human experience. But what happens when they ran out?
“One thing I feel sure of, and that is that the human race must finally utilize direct sun power or revert to barbarism,” Shuman told Scientific American magazine in 1911.Fighting during World War I destroyed Shuman’s plant. But in the end it was cheap, abundant oil that obviated his ideas – or seemed to.
The oil crises of the 1970s again piqued interest in CSP, and, in the 1980s, plants resembling Shuman’s began cropping up in the Mojave Desert. Then natural-gas prices plummeted and the cycle repeated itself. No new commercial-scale CSP plants were built for nearly 20 years.
Now CSP is poised for a second – or third, depending on when the count begins – renaissance. And this time, say experts, it’s here to stay. World CSP capacity is forecast to increase nearly 18-fold in the next five years, from its current 588 megawatt potential to around 10.5 gigawatts. (Very roughly, 100 megawatts is enough energy to power 80,000 houses.) More than half of that new CSP capacity will be installed in the United States.
Several factors are driving the CSP boom. Although utility companies have long viewed CSP as an option for generating electricity from the sun, they’ve hesitated to commit to the technology. That’s partly because CSP becomes efficient and cost-effective only at the megawatt (MW) scale.
Photovoltaics, by contrast, can be installed piecemeal on the kilowatt scale – a panel here, another there. And that’s why photovoltaics have so far dominated the solar market.Now, the specter of carbon regulation has shifted attention back toward CSP. The prospect of large-scale solar plants is again attractive. The “renewable portfolio” standard – which requires increased production of energy from renewable sources – has also encouraged investment in CSP. And the investment tax credit – a potential 30 percent credit on qualifying solar projects – has made investors more willing to risk capital in CSP ventures.
Solar is here to stay, now
“Twenty years ago, everyone thought the solar era was upon us, and then the industry basically went away when oil and gas got cheap,” says Cara Libby, project manager at the Electric Power Research Institute (EPRI) in Palo Alto, Calif. Now, “it certainly appears that solar is here to stay.”
For their part, power companies like CSP for old-fashioned reasons. For one, it uses a technology – steam-driven turbines – that is familiar after decades of use in coal-fired plants.
CSP plants also have thermal inertia. That means that, if a cloud passes overhead, they can continue operating for a time with the heat already gathered, and that’s without storage.
Assuming no rechargeable batteries, photovoltaic fields, by contrast, stop producing electricity when clouds arrive.
Technology for storing heat in molten salts, meanwhile, promises to extend CSP plants’ generating capacity well into the night.
But the bottom line is that natural-gas prices are volatile, an unknown for anyone trying to turn a profit. By comparison, CSP costs – when stretched over the life of a plant – are mostly (80 percent, by one estimate) related to installation. CSP maintenance costs are relatively small, and the sun, its fuel, is free.
“There’s a hedging aspect in building a solar thermal plant,” says Nathaniel Bullard, a solar-sector analyst with New Energy Finance in Washington. “Right now it makes sense to burn gas; it’s really cheap. But you could, in the future, end up losing your shirt on it.”
Inventor Thomas Edison, a contemporary of Shuman’s and the man who gave us the system of steam-generated electricity distributed by wires, told friends late in his life that “I’d put my money on the sun and solar energy. What a source of power!”
Earth has a natural “sun belt,” a swath of relatively empty subtropical deserts including the US Southwest, the Sahara, the Middle East, and much of Australia. By one estimate, installing CSP plants in just 1 percent of the world’s deserts – an area slightly larger than Ireland – could supply all the world’s electricity.
The German Aerospace Center calculates that, assuming high voltage, transmediterranean transmission lines, just 6,023 square miles of CSP in North Africa could keep all of Europe electrified.
In the US, CSP plants in the Southwest could generate 11,000 gigawatts (GWs) of electricity, says Mark Mehos, principal program manager of concentrating solar power at the National Renewable Energy Laboratory (NREL) in Golden, Colo. That’s roughly 10 times all the electrical generating capacity currently in place, including coal, nuclear, solar, and hydroelectric – more than enough for the country’s energy needs.
In other words, there’s plenty of sun. The real challenge is making CSP technology competitive with coal.
Currently, CSP costs about 14 cents per kilowatt-hour (kWh), within striking range of current combined-cycle natural-gas plants, in which a gas turbine generator generates electricity and a steam turbine uses the waste heat to generate more. A combined-cycle natural-gas plant produces electricity for about 12 cents per kWh.
Pulverized coal plants, on the other hand, generate electricity for 6 cents per kWh – less than half CSP’s cost. But, says Mr. Mehos, if you assume that future coal-fired plants will require carbon sequestration, then that cost moves up to about 10 cents per kWh. That means CSP prices still need to drop by nearly one-third to be competitive with future coal plants.
A plethora of CSP companies are racing to innovate and reduce costs. At this point, CSP technology comes in four general “flavors,” each with different perceived strengths and weaknesses.
Parabolic-trough systems focus the sun’s energy onto a tube running their length. Temperatures in the tube can reach 750 degrees F. A medium in the tube – sometimes synthetic oil that transfers its heat to water, sometimes water itself – collects heat to drive turbines. A second troughlike system, called a Compact Linear Fresnel Reflector, uses several mirrors to focus the sun’s rays on a single receiver tube above.
Trough technology benefits from being proven. That was Shuman’s design, and it’s the one the Mojave plants installed in the 1980s and ’90s. A planned 280-MW CSP plant near Phoenix will use trough technology, and store heat for electrical generation in molten salts.
‘Power towers’ more efficientBut experts say that, although it’s a known quantity, trough technology may be less efficient than newer, albeit less-tested, approaches. One reason: Newer systems achieve higher temperatures, which greatly increase efficiency.
So-called “power towers” – thousands of mirrors, or heliostats, directing the sun’s rays at a central tower – can achieve 1,300 degrees F. They also benefit from not having to pump the receiver fluid through tubing, an energy loss.
The first commercial scale “power tower” plant began operating near Seville, Spain, in 2007. The 11-MW plant resembles a gigantic, silver-petaled flower reflecting rays of light toward a central stamen. (Others compare it to the lidless Eye of Sauron in the “Lord of the Rings” movies.)
In the US, eSolar recently brought a 5-MW “power tower” demonstration plant on line near Lancaster, Calif. It includes a number of innovations, says Jim Shandalov, eSolar’s vice president of business development. Its relatively small mirrors – thousands of them about a yard square – rise no higher than four feet. Compared with troughs, which can be up to 10 feet high, or the Spanish plant, which has mirrors mounted on frames more than 120 square meters in area, the four-foot height keeps the wind profile down. A smaller profile also means fewer building materials.
Small, flat mirrors are also cheaper to manufacture, transport, and install, he says. An automated robot on a track can clean and maintain the mirrors, further cutting costs.Finally, new software calibrates each mirror individually, an improvement over the “two walkie-talkie men” method of yore, says Mr. Shandalov, “We’ve made it more efficient.” (He won’t say by how much – that’s a trade secret.)
A fourth CSP option uses a reflective parabolic dish. A Stirling engine, the basic design of which is 200 years old, sits at the dish’s focal point. About the size of a motorcycle engine, it contains hydrogen gas. When heated, the gas drives four pistons, generating electricity on the spot. Stirling Energy Systems and its partner company, Tessera Solar, use this approach in their SunCatcher. A 1.5-MW demonstration plant is slated to begin operating in January near Phoenix.
Most efficient method costs more
Some point out that this method’s large pedestals holding the glass parabolas, some 38 feet across, represent a cost that low-profile, flat-mirror approaches have successfully eliminated.
Nonetheless, in purely thermodynamic terms, the SunCatcher is the most efficient CSP approach so far. It converts 31 percent of the sun’s energy to grid-ready electricity. By comparison, photovoltaic ranges between 8 and 15 percent efficiency, and trough CSP between 15 and 19 percent.
The SunCatcher has one more advantage: The engines aren’t cooled with water. The hydrogen cools in an air radiator similar to that found in a car.
That’s important because, in the arid and semiarid regions of the desert Southwest, where CSP makes the most sense, water is already a hot-button issue. And it’s predicted to become more so.
“The Southwest is a great place to build solar, but it’s not a great place to build water-intensive solar,” says Peter Gleick, president of the Pacific Institute in Oakland, Calif., a nonprofit devoted to sustainability issues.
Air-cooling CSP is possible, but can decrease efficiency and – in some situations and regions – increase costs by 5 to 10 percent. Yet for some, it’s already a selling point. BrightSource Energy, a company developing a 400-MW “power tower” plant in the Mojave, touts the fact that its plant will be entirely air-cooled.
Other companies are developing new, cost-saving materials. SkyFuel in Albuquerque, N.M., is testing a reflective laminate material that, it says, is more durable than standard glass. Theoretically usable in any of the CSP approaches, it’s 10 to 20 percent cheaper than glass mirrors, says Andi Plocek, SkyFuel’s marketing director.
Many see cost-­effective heat storage as the biggest long-term hurdle for CSP. “The cost of storage is higher than we thought,” says Mehos.
Eventually, utilities will want to generate electricity from renewable sources through the night. To do that with CSP, they’ll need to store the sun’s energy.
Molten salts – used as fertilizer in agriculture – are one solution. But they’re also potentially difficult to handle. They freeze below a certain temperature, possibly clogging the system if allowed to cool. Another consideration with any storage is that with each transfer of heat between media, energy is lost and efficiency diminishes.
In other words, on the cusp of a CSP boom, which technology will dominate and how it will store heat is still very much an open question.
“It’s hard to predict who’s going to win in the end, if there is a winner,” says EPRI’s Ms. Libby: “We need to get more hardware on the ground and really test out all the ­options.”
