Solar 101

Summary

Solar energy is the most abundant renewable energy source, utilizing technologies that convert the sun's heat or light into usable energy. The two main types of solar technologies are photovoltaics (PV), which convert sunlight into electricity using semiconductors, and solar thermal, which harnesses the sun's heat for heating or power generation. Solar energy is clean and doesn't emit greenhouse gases, but challenges like efficiency and intermittency arise due to sunlight's dependence on location, season, and time of day. Effectively capturing solar energy remains a key challenge.
