By putting solar panels on your roof and an electric car in your garage, you could essentially drive for free. How soon can you start?
Electricity consumption is already higher than ever, and experts say it will only continue to rise. What are the long-term implications for your wallet? Find out.
Limitless clean energy from wastewater? Nah, let’s stick with clean coal
A Penn State lab has found a mind-blowing way to make hydrogen fuel from wastewater and seawater with no emissions. So why are we spending our billions on the pipe dream of burying the carbon dioxide we make burning coal?
CHIP is one of the more curious-looking entries in the 2011 Solar Decathlon and certainly the only home in the competition that incorporates a parking space. With its unusual boxy shape and exterior skin made from vinyl-coated fabric mesh, this home’s petite size of less than 800 square feet makes it the ideal candidate for urban infill projects.

Red wine offers scientists a clue to superconductive future
Scientists at a boozy office party discovered that red wine makes a metal compound superconductive, which could revolutionize energy transmission.
Japanese breakthrough will make wind power cheaper than nuclear
A surprising aerodynamic innovation in wind turbine design called the ‘wind lens’ could triple the output of a typical wind turbine, making it less costly than nuclear power.
Fire up those photovoltaics, ladies and gents … the 2011 Solar Decathlon is upon us. Here’s a sneak peak of the innovative Solar Decathlon houses.
Up and atom: The comeback of nuclear power
It’s climate-friendly and creates jobs, but as the U.S. reconsiders atom smashing, old worries about nuclear waste, meltdowns and price tags persist.
5 breakthroughs that will make solar power cheaper than coal
Solar technology charges forward despite Washington’s backward march. Just check out this solar cell printed on paper — MIT has found a way to print solar cells on just about anything, using low temperatures and vapor. The resulting printed paper cell is extremely durable and can be folded and unfolded more than 1,000 times with no loss in performance!
Beautifully simple design: The plastic bottle light
Cut a hole in a developing world roof big enough for a plastic soda bottle to fit snugly into. Fill a bottle with water and a little bleach and set it halfway into the hole cap side up. Voila, you now have a daytime light bulb. The sunshine is diffused by the water in the bottle and kicks off the light equivalent to a 50 watt bulb that costs nothing to run. See how it works.
