In short, solar energy is sunshine. It ranges from heat to ultraviolet energy, although its output is primarily yellow light.
Solar energy is created by the sun. The amount of solar energy that is delivered to the Earth each day is dependent on the weather and climate in certain regions of the world. Areas that have more sun will have more solar energy, while others that experience more rain will receive less.
The amount of solar energy that is produced on a daily basis is much greater than the amount of energy that is used on the Earth. Because of this, solar energy is potentially a viable source of energy to replace more costly and limited types of energy, such as electricity.
