One in four British homes could be fitted with solar heating equipment and 3,500 wind turbines could be erected across Britain within 12 years as part of a green energy revolution to be proposed by the government next week.

Cost effective devices expected on market soon Imagine windows that not only provide a clear view and illuminate rooms, but also use sunlight to efficiently help power the building they are part of. MIT engineers report a new approach to harnessing the sun's energy that could allow just that.

There are times in the history of our nation when our very way of life depends upon dispelling illusions and awakening to the challenge of a present danger. In such moments, we are called upon to move quickly and boldly to shake off complacency, throw aside old habits and rise, clear-eyed and alert, to the necessity of big changes. Those who, for whatever reason, refuse to do their part must either be persuaded to join the effort or asked to step aside. This is such a moment. The survival of the United States of America as we know it is at risk. And even more - if more should be required - the future of human civilization is at stake.

The Upper Great Plains Wind Energy Programmatic EIS Information Center Web site was launched September 11, 2008. This Web site is the online center for public information and involvement in the Upper Great Plains Wind Energy Programmatic Environmental Impact Statement. The U.S. Department of Energy, Western Area Power Administration (Western), and the U.S. Department of the Interior, Fish and Wildlife Service (Service), will prepare a Programmatic Environmental Impact Statement (PEIS) to evaluate the impacts of wind energy development within Western's Upper Great Plains Customer Service Region (UGP Region), which encompasses all or parts of the States of Iowa, Minnesota, Montana, Nebraska, North Dakota, and South Dakota; and on the Service's landscape-level grassland and wetland easements in North Dakota, South Dakota, and eastern Montana.

The challenge set by Ford Global Technologies is to design a Model-T for the 21st Century - an inexpensive, innovative and sustainable car. Deakin University is the only Australian university and one of only five worldwide invited to participate in the Challenge, part of the celebrations for the 100th anniversary of the fabled Model T; the car that changed the 20th Century. Deakin University's 'under wraps' design for the Ford Global Challenge left for Detroit on 29th August carried by Deakin's Tim de Souza (Chief Design Engineer) and Stuart Hanafin (Portfolio Coordinator). Deakin's project is code-named T2 ('TSquared').

Not this week. As part of the Solar Power International conference here, big businesses such as equipment maker Applied Materials Inc. and solar cell manufacturer SunPower Corp. rented out bars and restaurants and shut down the streets to serve up free drinks and food to executives who partied through the night. "It's amazing, the euphoria in the industry right now," Victoria Hollick, vice president of Conserval Engineering Inc., said as a disc jockey played songs like "Good Times" and "Celebration." The solar industry has good reason to celebrate right now.

Are you looking for a career path that you have complete control over every part of the business? No more boss to worry about. Starting a greenhouse business may be something to consider.

From the outside, there is nothing unusual about the stylish new gray and orange row houses in the Kranichstein District, with wreaths on the doors and Christmas lights twinkling through a freezing drizzle. But these houses are part of a revolution in building design: There are no drafts, no cold tile floors, no snuggling under blankets until the furnace kicks in. There is, in fact, no furnace.

Part of creating the ultimate sustainable planet will be our ability to find sustainable energy sources in a variety of means, such as sunlight, water flow, wind, and yes, even rain. We are of course speaking of the kinetic energy which can be harnessed from rain, which up until a few months ago, was not being considered for use in a consumer product... Lightdrops Umbrella This kinetic energy is created from piezoelectric material, which is able to convert mechanical energy into electrical energy. Now, we aren't talking about a whole lot of energy being created here, approximately 1 microwatt to 12 milliwatts per rain droplet. While not much in the large scheme of things, this technology has been put to use in a new LED umbrella called Lightdrops, which is able to self power an internal LED light using the rain from which it is protecting its user from.

Will Stewart has a guest post up at The Oil Drum on passive solar design techniques - Passive Solar Design Overview - Part 1. Also, at TOD, a post on the Passivhaus standard from another long-time commenter, marjorian - US Housing and the Passive Home Standard. Passive solar refers to the design and placement of a building to enable solar heating without the need for sensors, actuators, and pumps, in contrast to active solar, which utilizes pumps/blowers, sensors, and logic control units to manage collection, storage, and distribution of heat. The two techniques are not exclusive, however, and can work together effectively. As solar radiation (insolation) is a diffuse energy source, and not at the beck and call of a thermostat, passive solar design techniques are at their best when combined with other related methods, such as energy efficiency (insulation, weatherization, building envelope minimization), daylighting, passive cooling, microclimate landscaping, and a conservation lifestyle (i.e., temperature settings, raising and lowering of insulated shades, etc). Most of these topics will be covered in other articles, though passive cooling will be addressed in this series, which is intended as an overview, as a complete engineering treatment on passive solar design would require several dozens of articles.

Sustained growth of biomass is contingent upon consistent weather patterns which by no means are guaranteed in an age of global climate change.

Granted, the risk that a nuclear reactor might fail today is fairly small on a per plant basis. "clean coal", because this source of energy is our most abundant and cheap.

Next Tuesday in Las Vegas renewable energy industry leaders, experts, companies and other interested participants will meet in Las Vegas to discuss how the industry is faring amidst the current economic conditions during Renewable Energy World North America, the renewable energy's leading expo and conference in North America. "While some companies may have delayed their growth plans in reaction to the current economic situation, I am hearing that they do plan to hire as soon as the U.S. stimulus package begins to take affect." -- Katharine Hart, Online Job Sales Manager, RenewableEnergyWorld.com The show kicks off with a keynote round-table session that will set the stage for the 3-day event. During the session, leaders of the major renewable industry trade associations plus a senior executive from host utility NV Energy will take part in a round-table discussion on the economy, the economic stimulus bill and renewable energy initiatives likely to come from the Obama Administration and Congress. These individuals have their fingers on the pulse of their respective industries and should be able to shed light on the most current insights into what the next four years may hold for the industry.

March 3, 2009 Arizona based First Solar has achieved a major milestone in reducing the manufacturing cost for solar panels below the $1 per watt price barrier - the target necessary for solar to compete with coal-burning electricity on the grid or grid-parity. Using cadmium telluride (CdTe) technology in its thin-film photovoltaic cells, First Solar claims to have the lowest manufacturing cost per watt in the industry with the ability to make solar cells at 98 cents per watt, one third of the price of comparable standard silicon panels. The efficiency is in part due to a low cycle time - 2.5 hours from sheet of glass to solar module - about a tenth of the time it takes for silicon equivalents.

For all of solar power's positive attributes and benefits, the most obvious drawback it suffers from is its marriage to the sun; the sun must shine for the power system to work.

CleanTechnica has a post from San Francisco mayor Gavin Newsom on the city's proposal to build a wave power plant offshore - Wave Energy to Bring Power and Jobs to San Francisco. Today, San Francisco took a meaningful step toward turning the promise of renewable ocean energy into reality. We submitted a preliminary permit application to the federal government to develop a wave power project off our coast that we believe can generate between 10 to 30 megawatts of energy, with potential of up to 100 megawatts. When this project is fully operational, upwards of 100 jobs could be created in San Francisco. Ocean power is a true "game changer" in the area of renewable energy. When wave and tidal power technologies reach commercial scale, they are expected to be able to provide thousands of megawatts of power to our coastal communities, dramatically green our energy portfolios and create thousands of new American jobs. In San Francisco, we've been doing our part to spur these technologies by aggressively advancing tidal and wave power pilot projects. We are 100% committed to this challenge. Wave power is not a new concept. In 1887, San Francisco Mayor Adolph Sutro recognized the power of San Francisco's waves and built a wave catch-basin to harness the ocean's power. Over the next century wave power development took a backseat to our dependence on oil, with oil platforms built along our coasts to feed our oil addiction.

Presently, the world consumes in the neighborhood of approximately 18.5 TW [terawatts; 18,500 gigawatts (GWe)/18,500,000 megawatts(MWe)] with virtually no all-electric vehicles on the highways.

As part of the Senate's proposed tax stimulus plan, tax credits of up to $7500 have been included for plug-in electric vehicles! This is huge proposal and signifies the Senate is willing to work with President Obama to wean the United States off its dependency on foreign oil.

So far, CNG vehicles haven't made a blip on my radar screen, even though the group Natural Gas Vehicles for America (NGVA) estimates there are 150,000 NGVs on U.S. roads today and over 5 million worldwide. It took a phone call from sunny Southern Utah to clue me in to recent developments, which include a local refueling station overflowing with CNG-hungry vehicles. There are about 1500 CNG refueling stations in the US, which is about the same number of commercial stations offering E85 ethanol blends. Utah has a total of 91 CNG filling stations, most of which are reserved for commercial fleet use, but there are 20 open to the public. According to an article by the Associated Press, you could drive Utah from top to bottom and hit 22 different stations offering compressed natural gas.

Last week saw the opening of the first hydrogen fuelling station in England. The station is based at Birmingham University, where experiments are being carried out to test the viability of hydrogen in transport applications, as part of Birmingham's 'Science City' hydrogen energy project.
