Meanwhile in the Future: We Have Changed the Climate with Wind Turbines

According to the Center for Climate and Energy Solutions, about 2.3 percent of America’s power is generated by wind. But wind power is becoming wildly popular all over the world. What would happen if a company put up so many wind turbines that they actually changed the climate on Earth? That’s the subject of this… » 7/21/15 4:12pm 7/21/15 4:12pm

Saltwater and sludge could give us an inexhaustible supply of energy

Splitting water into hydrogen and oxygen is generally considered a fantastic way to get a renewable power source. The problem is how exactly you go about splitting the water. Current methods require some power input in order to kickstart the reaction, reducing its effectiveness as a sustainable power source, since… » 9/23/11 6:40am 9/23/11 6:40am

We're one step closer to cheap, abundant biofuel

Biofuels are made from carbohydrates and fats in corn and other feedstock. This is a wasteful process because it leaves behind all the protein, a far more abundant substance. As a result, one of the big questions for alternative energy researchers is how we can pull biofuel from protein. Especially because proteins… » 3/08/11 7:20am 3/08/11 7:20am

The Next Alternative Energy Solution? Human Hair

Milan Karki, an 18 year-old from a rural village in Nepal, has invented a type of solar panel that replaces expensive silicon with cheap, easily replenished human hair. Melanin, the pigment in human hair acts as a conductor for solar energy, and hair, unlike silicon, can be easily replaced, giving the panels a longer… » 9/10/09 9:30am 9/10/09 9:30am
