Organizing and summarizing search results for youOn Earth, we harness and convert solar power from the sun into usable energy using photovoltaics or solar thermal collectors. The Earth receives 174 petawatts (PW) of incoming solar radiation (insolation) at the upper atmosphere. Approximately 30% is reflected back to space while the rest, 122 PW, is absorbed by clouds, oceans and land masses. This energy goes towards weather, keeping the temperature of the Earth at a suitable level for life, and powers the entire biosphere. However, on the earth's surface, solar energy is a variable and intermittent energy source.4 SourcesHow Does Solar Work? - Department of Energy
