The sun is the ultimate renewable energy source. Every day for about ten billion years, the sun has poured out unimaginable amounts of energy. The Earth, orbiting at a distance of 150 million kilometres from the sun, intercepts a tiny fraction of this solar output. At the Earth's surface, incoming energy from the sun is absorbed by the land, water and atmosphere, and converted into measureable heat. This heat acts like a giant engine, creating winds and currents in our atmosphere, oceans, and rivers.
Most of the sun’s energy is emitted as visible light. To harness the sun as a source of energy, we need to convert it from visible light into heat or electricity.
