The whole thing is happening without flashy ad campaigns, so it's not surprising if you've never heard of municipal solar financing. But the financing program, also known as property tax financing, is a veritable underground solar revolution. It all started in Berkeley, CA with the Berkeley FIRST Program, which allows homeowners to pay for solar panels through property tax bills over a 20 year period. The bills carry a fixed interest rate and stay with the house, so there's no need to worry about paying for panels on a house you don't live in anymore. The Berkeley program was so popular that California passed the AB811 bill to let any interested city in the state launch a similar program.

Large-scale solar power is beginning to take on the job of meeting the demands made by California's air conditioners for electricity. Pacific Gas & Electric and Brightsource Energy today announced they have expanded a series of solar power contracts for a total of 1,310 megawatts of electricity - enough to power 530,000 California homes during peak hours with energy from the Sun. Completion of the first project will nearly double the amount of solar thermal electricity produced in the United States.

Officially grid-connected and set to work this week in Germany is a new wind tower from ATS. The novel tower construction allows very high hub heights that may increase a turbine's yield by 20% or more. With its hub height of 133 meters (436 feet), the system has an overall height of 180 meters (590 feet). "This is a great day for wind energy." said Frans Brughuis, Managing Director of the tower construction specialist Advanced Tower Systems (ATS). "Now the pilot project can demonstrate the high cost-effectiveness and efficiency of the ATS concept," The system, one of the largest wind energy systems with hybrid tower in the world, is installed at Germany's Windtest test field at Grevenbroich, near Cologne.

If you don't feel like trying to go back to school, or maybe school is not for you, try vocational schooling.

Technology Review has an article on making solar power cheaper using concentrators combined with PV panels - Cheaper Solar Concentrators. Skyline Solar, a startup that today announced its existence to the world, has developed a cheaper way to harvest energy from the sun. The company's solar panels concentrate sunlight onto a small area, reducing the amount of expensive semiconductor material needed to generate electricity. The technology will bring the cost of solar power in line with the average cost of electricity, at least in sunny areas, says Ben Eiref, Skyline Solar's director of product management. Currently, solar power can be far more expensive than electricity from conventional sources; many governments have resorted to subsidies to increase its use.

Green building of the week from Inhabitat is this vertical farm proposed for Vancouver - Amazing Skyscraper Farm for Vancouver. I'll believe vertical farms work when I see it, but I'd like to see one tried, purely for the sake of showing how successful they can (or can't) be. Vertical farms are one of our favorite future-forward concepts for creating sustainable cities. Providing locally-grown produce and food will not only help us reduce our carbon emissions significantly, but also help us become healthier. Romses Architects recently came up with an amazing concept for a vertical farm in Vancouver as part of the City's 2030 Challenge. Complete with a tower for growing fruits and vegetables, a livestock grazing plane, a boutique dairy farm, commercial space, transit lines, renewable energy and more, the Harvest Green Tower has the potential to be a food growing, energy producing, living, breathing sustainable transit hub.

Jerome a Paris has an excellent (and long) article at TOD about the economics of wind power - The cost of wind, the price of wind, the value of wind. I'd like to try to clear some of the confusion that surrounds the economics of wind power, as it is often fed and used by the opponents of wind to dismiss it. As I noted recently, even the basic economics of energy markets are often wilfully misunderstood by commentators, so it's worth going in more detail through concepts like levelised cost and marginal cost, and identify how different electricity producers have different impacts on electricity (market) prices (which may or may not be reflected in retail prices) and have different externalities. Value for society of a generation source may also include other items that are harder to acount in purely monetary terms (and/or whose very value may be disputed), such as the long term risk of depletion of the fuel, or energy security issues, such as dependency on unstable and/or unfriendly foreign countries or vulnerable infrastructure.

President Obama's proposed $9.9 billion Energy Department budget contains up to $28 million for a Pantex wind farm that would be designed to meet the nuclear weapons plant's energy needs. The Pantex Renewable Energy Project would be built on land in the vicinity of the plant and could generate surplus electrical power that could be sold to utilities, according to budget documents. Preliminary plans call for the wind farm to be built by 2012. The project's overall scope would depend on future funding, but plans call for enough wind turbines to generate up to 75 megawatts of electrical generating capacity. Initial funding would only support construction of a 10- to 15-megawatt system.

A new public opinion poll shows strong bipartisan support for a national Renewable Energy Standard requiring utilities to generate at least 25 percent of their electricity from renewable energy sources by 2025. The poll was released Tuesday as the wind energy industry gathered in the Windy City for the American Wind Energy Association's WINDPOWER 2009 Conference and Exhibition. For these 18,000 attendees and 1,200 exhibitors renewable energy means wind.

U.S. Department of Energy (DOE) Secretary Steven Chu today announced selection of 53 new wind energy projects for up to $8.5 million in total DOE funding. These projects will help begin to address market and deployment challenges identified in DOE's 2008 report: "20% Wind Energy by 2030." Increasing wind energy generation will be a critical factor in achieving the Obama Administration's goals for clean energy, while also supporting new green jobs. Secretary Chu made the announcement by video at the WindPower 2009 Conference in Chicago this week. "Wind energy is one of our most promising renewable energy sources," said Secretary Chu. That's why I'm pleased to make this announcement today. By continuing to make investments in renewable energy we can cut our dependence on foreign oil and invest in a clean energy agenda that creates jobs and puts money back into the pockets of consumers."

REW reports the world's biggest solar thermal tower has opened in Spain - World's Largest Solar Power Tower Commissioned. Abengoa Solar has begun commercial operations of the world's largest solar power tower plant, a 20 MW installation. The company claims that the performance of the power plant, the so-called PS20, has exceeded its design output in the wake of its three-day production and operational testing period. Located at the Solúcar Platform, near Seville, Spain, PS20 is the world's second power tower plant in commercial use and features a number of significant technological improvements with respect to its predecessor, PS10. These enhancements include a higher-efficiency receiver, various improvements in the control and operational systems, and a better thermal energy storage system. PS20 consists of a solar field made up of 1255 heliostats with a surface area of 1291 square feet each. This reflects the solar radiation it receives onto the receiver, located on the top of a 531 foot-high tower, producing steam which is converted into electricity generation by a turbine. Plant construction was carried out by Abener.

A new battery made from non-toxic materials abundant in the Earth's crust could revolutionize the electric vehicles segment. The battery, powered by LifePO4 - a material used in advanced lithium-ion batteries, was developed by Universite de Montreal researchers.

The wind energy industry in the United States installed 2,836 megawatts of new generating capacity through the end of March, bringing total installed generating capacity in the country to 28,206 MW, the American Wind Energy Association announced. The national trade association for the wind energy industry in the U.S. issued its report Tuesday on projects that were completed in 15 states during first financial quarter of the year.

What do you do if you build a wind farm smack dab in the middle of a major bird migration route, and want to avert the anger of conservationists? Put up a radar system that's designed to shut down the entire thing when it detects a mass of birds on the way. That's what's been done at the 202 MW Peñascal Wind Farm in Texas: System Detects Birds Approaching Four Miles Away The system uses radar originally developed for NASA and the US Air Force to detect birds as far as four miles away, The Guardian reports. When it picks up the approaching birds, it analyzes the existing weather conditions and determines in real time whether those birds are in danger of flying into the blades. The system then automatically restarts the turbines when the birds have passed.

In pursuit of Governor Deval Patrick's goal of 2,000 megawatts of wind power in Massachusetts by 2020, the Secretaries of the Executive Office of Transportation (EOT) and the Executive Office of Energy and Environmental Affairs (EEA) announced a project to install a utility-scale wind energy project on state land adjacent to the Massachusetts Turnpike's Blandford Rest Area. "This wind energy project is good for the environment and it will help create jobs within our clean energy economy." -- Massachusetts Governor Deval Patrick Following studies showing significant wind power potential, the Massachusetts Turnpike Authority (MTA) today issued a Request for Proposals (RFP) to install wind power at the 68-acre site in western Massachusetts.

American Electric Power (AEP) is doubling its goal of adding 1,000 megawatts (MW) of renewable energy to 2,000 MW by the end of 2011. This would bring the company's total renewable energy portfolio to more than 2,600 MW by the end of 2011. AEP has added 903 MW of wind generation since 2007, when the company committed to its original goal of adding 1,000 MW. AEP also set a new energy efficiency goal in 2009 to reduce consumption by 2.25 million megawatt-hours by the end of 2012. "Continuing to diversify our fuel mix with more renewable resources will allow us to meet our customers' energy needs and reduce our carbon footprint," said Michael Morris, AEP's chairman, president and CEO. "We can support development of a lower-carbon energy future through a combination of increasing renewable energy; driving the development of a new, interstate extra-high voltage transmission system to bring that renewable energy to market; promoting energy efficiency; and further developing advanced coal technologies such as carbon capture and storage."

The US EPA has released their latest list of the top consumers of green power in the US: The Green Power Partnership works with a wide variety of leading organizations - from Fortune 500 companies to local, state and federal governments, and a growing number of colleges and universities. The following Top Partner Rankings highlight the annual green power purchases of leading organizations within the United States and across individual industry sectors.

Hot on the heels of the release of the NRDC's renewable energy map, we have another piece of first-rate energy geek eye candy: NPR: Power Hungry: Visualizing The U.S. Electric Grid. This map will let you check different sources (with separate maps for wind and solar, in addition to traditional sources), and toggle transmission lines and other features on and off. My only gripe is that you can't zoom the maps, which in some cases makes it a challenge to click on the circle for a particular power plant.
