Solar Concentrator 37°33’38.0”N, 5°19’53.1”W. The Gemasolar Solar Concentrator in Seville, Spain, contains 2,650 heliostat mirrors that focus the sun’s thermal energy to heat molten salt flowing through a 460-ft-tall (140m) central tower. The molten salt then circulates from the tower to a storage tank, where it is used to produce steam and generate electricity. In total, the facility displaces approximately 30,000 tonnes of carbon dioxide emissions every year. (Photo by Daily Overview/DigitalGlobe, a Maxar Company)
