Cooking Steaks with Sunlight in South Africa (video)

Using coal and kerosene to fuel a stove is both costly and hazardous. Social entrepreneur Crosby Menzies hopes it will become a thing of the past in Africa. He rolled out his solar cooker, a satellite-dish shaped oven that uses sunlight to cook meals, in the Johannesburg township of Soweto. By employing locals like Mthobisa Cebekhulu, he believes he can bring it to other impoverished parts of the continent.

by J. Matthew Roney, Earth Policy Institute In China, wind power is leaving nuclear behind. Electricity output from China’s wind farms exceeded that from its nuclear plants for the first time in 2012, by a narrow margin. Then in 2013, wind pulled away — outdoing nuclear by 22 percent. The 135 terawatt-hours of Chinese wind-generated electricity in 2013 would be nearly enough to power New York State.

A Bicycle-Powered Water Pump (Malawi, Africa)

Sitting quietly at Butterfly, on the shores of Lake Malawi, it always struck me as odd when I would hear of people in the U.K. and the ‘leisure time’ they allotted themselves to keep fit.

Zero Net Energy Households

A "zero net" home is a household with zero net energy consumption and zero carbon emissions annually — essentially, the idea of a zero net home is a building with a virtually invisible carbon footprint. As renewable and clean energy sources become more affordable and accessible to everyday homeowners, we should hopefully see an increase in both zero net homes, and homes that consume slightly more energy than they produce, […]
