What Is Solar Energy?

Solar Energy, called solar radiation, is direct radient energy from the sun. It is produced by nuclear fusion and comprised almost entirely of electromagnetic radiation in the form of light, heat, and the solar wind.

Light - is emitted by the sun and acts both as a particle and a wave.

Heat - warms the earth

Solar wind - charged particles sent through space which interact with the Earth's atmosphere producing the auroras.

The sun as an energy source still remains virtually untapped. It is estimated that the sun could freely provide enough energy to light ten 100 watt light bulbs- for every square meter of land on earth.
