As the title suggests, this version of Chelsea Green's original 1999 version expands the scope to include commercial-scale wind turbines used in distributed applications. As such, this book includes wind turbines of all sizes. This edition makes a distinction between large numbers of commercial-scale wind turbines used in central-station power plants, or wind farms, and wind turbines used singly or in small clusters both on and off the grid.

Once an importer of Germany's solar technology, South Korea is now partnering with the world champion to help build up its own home-grown photovoltaic (PV) industry with an eye on supplying the growing Asian market in the future. By Jane Burgermeister, European Correspondent

New solar thermal technology overcomes a major challenge facing solar power – how to store the sun’s heat for use at night or on a rainy day. As researchers tout its promise, solar thermal plants are under construction or planned from Spain to Australia to the American Southwest. By David Biello

Andreas Nöhrig was sitting in the sunny garden of an eco-hotel on the Canary Islands and felt disturbed by the constant humming of the diesel generator, and asked the manager why he does not use the abundant solar energy. „Too expensive“, was the answer, although a kilowatt hour of electricity from the generator is also everything but cheap. „That was the moment I decided to develop a solar technology which costs only a fraction of today’s PV.”

Green Cross International Founder Mikhail Gorbachev has urged world leaders and the private sector to make big investments in solar energy swiftly as a way out of the current economic crisis and as part of an emergency response to climate change.

Smart federal policies needed to maintain growth and meet President Obama’s renewable energy goals.

A new study on the installed costs of solar photovoltaic (PV) power systems in the U.S. shows that the average cost of these systems declined significantly from 1998 to 2007, but remained relatively flat during the last two years of this period.

A new study from Energy Watch Group "Wind Power in Context - A Clean Revolution in the Energy Sector" shows that there has been exponential growth in wind power capacity since the early 1990s.
