In one way or another almost every form of energy we use originates as energy from the Sun. Solar energy directly powers photovoltaic cells and thermal collectors. Indirectly we get power from plants grown by the Sun oceans heated by the Sun and Earths weather systems sustained by the Sun. Even the energy stored in fossil fuels originated as energy from the Sun captured by plants and animals millions of years ago. Physics Solar Workshop explores the topic of solar energy focusing on photovoltaic cells.
