(PhysOrg.com) -- Last week, the Gemasolar power plant near Seville, Spain, became the first commercial solar thermal power plant to supply uninterrupted power for a full 24 hours, according to builders Torresol Energy. In contrast to photovoltaic solar cells, which use the sun’s light to generate electricity, solar thermal plants use the sun’s heat to run steam turbines and generate electricity. One of the biggest advantages of using heat is that it can be stored more easily than light, allowing for electricity production to continue even after the sun sets.
