World solar power topped 100,000 Megawatts in 2012

The world installed 31,100 megawatts of solar photovoltaics (PV) in 2012—an all-time annual high that pushed global PV capacity above 100,000 megawatts. There is now enough PV operating to meet the household electricity needs of nearly 70 million people at the European level of use.

A new approach to solar power

A new approach to solar power

Systems to harness the sun’s energy typically generate either electricity or heat in the form of steam or hot water. But a new analysis by researchers at MIT shows that there could be significant advantages to systems that produce both electricity and heat simultaneously. The new study incorporates thermoelectrics — devices that can produce an … learn more→
