It seems like a strange question, but have we run out of good places to build wind farms? On the face of it, one would think that a country as large at the U.S. is a long, long way from a time when we don't have the space to put up another turbine, but that's the question that Renewable Energy World is asking. Their answer?

When we heard that Mitsubishi and the Tokyo Institute of Technology (TIoT) were working on a way to use power generated while a windmill spins at night, it got us thinking. What's so special about wind power produced overnight?

Now that Audi is finally moving into the arena of electric cars, it has decided to also invest in renewable energy production. The German automaker has already installed an extensive array of solar panels at its main factory in Ingolstadt, which will be supplemented by up to 14,000 megawatts of wind power in the future.

From time to time, we've been known to ponder some stuff that non-greenies would have no interest in, but that's what happens when a passion for all things green takes over. For example, we've always thought that a great Google Earth app would be one that shows automotive plants across the globe, but why stop there. Throw in things like locations of wind farms, solar parks and a hyrdo-plants and we would start to drool. Well, General Motors either shares a similar vision or company officials are

One of the reasons that a vehicle powered by something other than gasoline is such a popular idea in the U.S. is that it helps us become less reliant on other countries for our transportation needs. To this end, biofuels and electric vehicles offer great potential to use local sources of energy in our vehicles. To get a handle on how much green electricity – wind, geothermal, solar, etc. – is available in the U.S., the Insitute for Local Self-Reliance (ILSR) has conducted a study on

Not only has a name been decided on – the Nemesis – but Ecotricity founder Dale Vince's pet electric car project is now sitting in Vince's driveway. Well, it is when he's not out driving it.

A British man named Richard Jenkins has just broken the world land speed record for a wind-powered vehicle. The high-tech contraption he used is called the Greenbird, the fifth wind-powered vehicle Jenkins has built. The resourceful Brit designed Greenbird himself over the course of a decade and built the machine almost completely from carbon fiber. Interestingly, Greenbird was sponsored by Ecotricity, the company currently working to build an electric Lotus that will be charged using electricit

One of the primary reasons that current wind turbines have to be so large is that most of the energy is lost as the air flows off the end of the blades. That size increases the cost and reduces the density of turbines that can be installed. FloDesign has developed a wind turbine that incorporates ideas from jet engines, including a shroud to duct air over the turbine blades. Unlike previous ducted turbine designs, this one is claimed to be able to self align and still work effectively at up to 2

One of the things you'll hear critics of renewable energy often say is that the sun doesn't always shine and the wind doesn't always blow. But of course we know that isn't the case. If you go high enough from the earth's surface, the sun never stops shining and though no one has seen it, the wind is always blowing. We've talked about beaming the solar energy to earth before and we have even shown you this particular wind-powered energy producer before. At the time, some commented it would never

Chrysler may be slow to the party in introducing production hybrids and electric vehicles, but that doesn't mean they haven't been working on cleaner energy. The company has been cooperating with university researchers on growing biofuel feed stocks on brownfield sites, for example. They have also been growing potential biofuel crops at their Chelsea, MI proving ground as an alternative to grass. The company's latest effort is a wind power project, also at the Chelsea track.

One problem with wind power is that you can never be sure when the wind will be blowing. If you rely on wind power, you've got problems when the weather chooses not to cooperate, which is like... always! One obvious way to collect the excess electricity to be used later would be with big batteries, but there are other ideas regarding the best way to store the power. Take for instance this scheduled power plant in Dallas Center, Iowa. In lieu of storing the power as electricity, the plan for this
