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. While PV production has become increasingly concentrated in one country—China—the […] … learn more→

After record 2012, world wind power set to top 300,000 megawatts in 2013

Even amid policy uncertainty in major wind power markets, wind developers still managed to set a new record for installations in 2012, with 44,000 megawatts of new wind capacity worldwide. With total capacity exceeding 280,000 megawatts, wind farms generate carbon-free electricity in more than 80 countries, 24 of which have at least 1,000 megawatts. At […] … learn more→

Wind surpasses nuclear in China

Wind has overtaken nuclear as an electricity source in China. In 2012, wind farms generated 2 percent more electricity than nuclear power plants did, a gap that will likely widen dramatically over the next few years as wind surges ahead. Since 2007, nuclear power generation has risen by 10 percent annually, compared with wind’s explosive […] … learn more→

On the road to clean energy in Germany: Lessons for the United States – Part 3

The third stop on our renewable energy tour of Germany was the state of North-Rhine Westphalia— the industrial, steelmaking, and coal mining center of the country—where we learned about the economic and social ramifications of Germany’s transition away from coal to renewable energy, and what lessons might be applied to the U.S. Phasing out coal […] … learn more→

Slow growth in the geothermal power industry in the U.S.

In the last few years, the growth in the geothermal power industry in the U.S. has been slow but consistent. Geothermal Energy Association’s recent press release reveals fresh numbers showing a net gain of 91 MW in 2011, making the new total capacity 3187 MW – significantly more than any other country in the world. […] … learn more→

Wind tops 10 per cent share of electricity in five U.S. states

A new picture is emerging in the U.S. power sector. In 2007, electricity generation from coal peaked, dropping by close to 4 percent annually between 2007 and 2011. Over the same time period, nuclear generation fell slightly, while natural gas-fired electricity grew by some 3 percent annually and hydropower by 7 percent. Meanwhile, wind-generated electricity […] … learn more→

The Desertec Project – The brightest solar project so far?

A look at the list of the World\’s 50 largest electricity-producing solar power stations is quite startling – every single one of them was completed between 2008 and now. A further look at the pending projects over the next few years shows that this growth certainly isn\’t going to halt anytime soon – there are […] … learn more→

Harnessing the sun\’s energy for water and space heating

The pace of solar energy development is accelerating as the installation of rooftop solar water heaters takes off. Unlike solar photovoltaic (PV) panels that convert solar radiation into electricity, these \”solar thermal collectors\” use the sun\’s energy to heat water, space, or both. … learn more→
