Offshore Wind Park (5/13)

Dozens of wind farms are up and running, with hundreds more planned as developers scramble to take advantage of Scotland's blustery climate and lucrative subsidies for renewable energy. Offshore wind parks could produce significantly more energy than onshore installations. Engineers, however, still struggle with rough conditions and high costs. (Photo: Reuters)
