Just outside Seville, in the desert region of Andalucia, Spain, sits an oasis-like sight: a 100-meter-high pillar surrounded by rows of giant mirrors rippling outward. More than 600 of these mirrors, each the size of half a tennis court, track the sun throughout the day, concentrating its rays on the central tower, where the sun’s heat is converted to electricity — enough to power 6,000 homes.
When most people think of clean technology and renewable energy, they think of the two industry stars: solar and wind power. In addition to their promise to replace fossil fuels, they're iconic and aesthetically pleasing. But other clean technology solutions have the potential to shine and make equal, if not greater, contributions to our success in weaning off fossil fuels. One of the most promising of these solutions is biogas.
