I'm Just Sittin' Here Watchin' the Wheels Go Round and Round

Watching Wind Turbines in the Snow turns out to be a clever solution to the practical reality that wind farms are simply too large to study in a wind tunnel. This holds promise for improving the efficiency of wind farms, which are steeply on the rise in the U.S. in recent years. Curiously, the rise in wind power is being facilitated by more flexible gas power plants that can pick up the slack on a moment's notice, helping to make up for one of wind power's biggest problems: It's lack of consistency.

A little sunshine on a rainy day...

The Virtual Power Plant: "Critics of renewables have always claimed that sun and wind are only intermittent producers of electricity and need fossil fuel plants as back-up to make them viable. But German engineers have proved this is not so." A pilot program funded by the German Federal Ministry of the Environment offers a rebuttal to critics who claim renewable energy sources have an insurmountable variability problem.

RIP Hermann Scheer (1944-2010)

Hermann Scheer - long-serving German parliamentarian, "Europe's Al Gore," father of the feed-in tariff, and perhaps the most important green politician of our time - died yesterday at the age of 66. [more inside]

Don't be Carbon-emitting?

Google, an internet search company, announced a US$ 4.4 trillion proposal for reducing U.S. dependence on fossil fuels by 2030. Google CEO Eric Schmidt, chided political leadership in the U.S. and the rest of the world for not showing initiative on the issue. Google's philanthropic arm, Google.org has already made significant investments in alternative energy solutions (previously) that will naturally tie in to this plan.Google stock has bounded on the news, but is their plan the way to go?

End of the World? ABC wants your ideas

Earth2100.tv is a project by ABC (video preview) to solicit ideas from the public and experts about the dangers facing world in the next 100 years. "The world’s brightest minds agree that the “perfect storm” of population growth, resource depletion and climate change could converge with catastrophic results. We need you to bring this story to life."

Is it time to look at Renewable Energy sources again?

Aurore, a renewable energy (RE) service provider in South India has been designing and developing RE products like solar lanterns and street lights, arranging for microfinance to support installation in remote villages and winning prestigious awards for their work. Cleaner, safer and cheaper than fossil fuels, their business philosophy is grounded in a greater vision than mere profit.

A True Convergence of Drinking and Driving

Saab's new 9-5 2.0T Biopower sedan runs on regular boring old gas and pumps out a respectable 148 horses. But, because its an FFV (Flex-Fuel Vehicle), fill it up with E85 ethanol (or grain alcohol to you, rummy) and, with the turbo (especially suited for use in ethanol powered vehicles because of ethanol's higher octane), the power is boosted to 184 horses while reducing the bulk of emissions and using a renewable energy source. Only problem is that there are only a little over 300 ethanol fueling stations in the US, it should be noted that the car is not aimed at the US market so our loss is Europe's gain (though not for long).

Read about it last night in the latest issue of Popular Science. Previous MeFi ethanol post.
