This document compares the land usage in square meters per gigawatt hour (m2/GWh) of electricity generated for different power plant types. A 110 megawatt geothermal flash plant uses the least amount of land at 160 m2/GWh, while a 95 megawatt hydroelectric plant requiring a reservoir uses the most land at 250,000 m2/GWh. Nuclear, coal, wind, and solar photovoltaic plants require between 1200 to 7500 m2/GWh, and a 47 megawatt solar thermal plant uses 3200 m2/GWh of land.
