Question

Quizplus · Accepted Answer

Power towers, parabolic troughs, dish/engine concentrators, and photovoltaic systems all directly utilize solar energy by converting sunlight into electricity or heat. Vapor hydrothermal (geothermal) energy, however, relies on the Earth's internal heat, not direct solar energy, to generate electricity.
