Cheaper, More Reliable Solar?

A recent renewed interest in alternative energy technologies has also revitalized interest in solar thermal technology, a type of solar power that uses the sun’s heat rather than its light to produce electricity.

Although the technology for solar thermal has existed for more than two decades, projects have languished while fossil fuels remained cheap. But solar thermal’s time may now have come — and mirrored arrays of solar thermal power plants may soon bloom in many of the world’s deserts. (Geotimes)
