Getting a solar system installed on your house is decidedly complicated. There is no centralized system, only contractors who you may or may not be able to trust. Prices for installation vary wildly, as do prices for the modules themselves. But in California, where things are getting a bit more consolidated and simplified, one retailer is trying to make solar easy. And it's Wal-Mart. Or, Sam's Club in nine California stores: Corona, Murrieta, Glendora, Ontario, La Habra, Chino, Long Beach, Fountain Valley, and Torrance.

A while back we reported (with some skepticism) a report coming out of China that said they would be producing over 100 gigawatts of wind by 2020, a 1,500% increase. Little did I know that the United States was, at the same time, on track to actually beat that! A report from Emerging Energy Research, a cleantech consulting firm, points out that the U.S. is now the world's fastest growing market for wind power. Last year 5 gigawatts of wind power were installed, and 2008 will break the record again with 8 new gigawatts under construction. The U.S. will shortly be the world's largest producer of wind energy, surpassing Germany's 22 gigawatts.

Wind power truly is a great resource. We should be using lot's more of it. And solar, biomass and geothermal, etc. But, please ask yourself why taxpayers should foot the bill for oil billionaire T. Boone Pickens, so he can connect his intended wind farm to government subsidized transmission line infrastructure? Heck, his financial statement is not bleeding red ink like the U.S. Treasury.

If ever there was a car made for the times, this would seem to be it: a sporty subcompact that seats five, offers a navigation system, and gets a whopping 65 miles to the gallon. Oh yes, and the car is made by Ford Motor (F), known widely for lumbering gas hogs.

Last year, we featured a nightclub lit entirely by LEDs, but here's an office building that is said to be the first to be lit by 100% LED light. The lighting was provided by the Netherlands-headquartered Royal Philips Electronics. To showcase the potential of LED light, Philips designed the lighting system to be warm and visually comforting. A total 422 LED fixtures were installed into the building's false ceilings. The offices are lit with fixtures that incorporate 12-16 high power LEDs, each rated at 2.6 watts. LED spotlights are used to illuminate the corridors.

Previously seen in the Sustainable Dance Club in Rotterdam, this is Britain's first exposure to such technology. The rest of the power needed will come from a wind turbine and solar energy system, with any surplus used to power private homes in the area. The club will also be installing the latest air flush, waterless urinals, low flush toilets and automatic taps to ensure maximum water saving plus less greedy air conditioning units.

The Bush administration yesterday unveiled but immediately disparaged a proposal to seek public comment on whether the government should regulate greenhouse gas emissions under the Clean Air Act, declaring at the outset that the proposed approach would be unworkable.

Plans to develop the world's largest tidal power project off the coast of Scotland and Northern Ireland have been unveiled today by ScottishPower. Three sites will initially be developed with a combined outpout of 60MW. Two of the sites are in Scotland in the Pentland Firth and the Sound of Islay, with the third off the North Antrim coast in Northern Ireland. The projects will use the Lànstrøm tidal turbine d

A new breed of solar tower may soon be sprouting up in Namibia, providing the nation with a carbon-free source of electricity and food during the day and night. At one and a half kilometers tall and 280 meters wide, these massive solar updraft towers could potentially produce 400MW of energy each - enough to power Windhoek, the nation's capital. Proposed by intellectual property company Hahn & Hahn, the towers generate energy by forcing heated air through a shaft lined with wind turbines. Additionally, the base of each tower will function as a 37 square km greenhouse where crops can be grown.

Last night was the tenth time since June 2007 that an extension of wind and solar tax credits have gone to the floor of the Senate. Seven times they have been stuck in bills that have gone to the floor of the House of Representatives. And they're still not law.

Here at Inhabitat we love to see innovative reuses for organic waste, and so we're perpetually fascinated by the potential of poo to be used as a renewable source of energy. Last week Dutch agriculture minister Gerda Verburg announced a groundbreaking development for the field as she unveiled the world's largest biomass power plant to run exclusively on poultry manure. The plant will convert a third of the nation's chicken waste into energy while running at a capacity of 36.5 megawatts - enough to power 90,000 homes!

Not sure whether a wind turbine on your property would generate enough energy to be worth the effort? Stew no more: the Carbon Trust has launched a new "Wind Yield Estimation Tool" on its Website. The tool lets users calculate their annual mean wind speed, potential energy generation and carbon savings based on postcode, landscape and type of wind turbine. According to the Carbon Trust, the tool is the "most rigorous of its kind" and is based on 30 years of data from the Met Office's 220 weather stations.

Denmark's DONG Energy and Siemens today announced they've signed off on "the world's largest offshore wind turbine agreement." Under the pact, Siemens will deliver up to 500 wind turbines for DONG's development of offshore wind energy installations in northern Europe. Once deployed, the turbines are expected to have a total power-generating capacity of 1,800 megawatts.

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.

OK...gas prices are getting out of hand, and carbon emissions have been out of hand for a long time. So let's kill two birds with...well...five stones. We generally focus on high-technology here at EcoGeek, and how we can save energy with smart designs. But sometimes, there are simpler ways. In fact, an absolutely tremendous amount of gasoline could be saved in America with some very simple measures. We break it all down and figure out how much gas can be saved with some stupidly simple techniques.
