Mega Solar: the World’s 13 Biggest Solar Thermal Energy Projects : EcoWorldly: "Solar thermal energy plants focus the glare of the Sun’s rays on a central location to create heat, which is then turned into electricity. Various methods exist to concentrate the solar radiation, including parabolic troughs, power towers with mirrors that track the Sun (heliostats), parabolic dishes, and Fresnel reflectors.
