We can't see energy and we can't touch it, but we can see and feel what it does.
Solar energy is the energy in the sun's rays.
It is produced deep inside the sun. Only a small fraction of the energy from the sun reaches the earth, but it is enough to warm and light the earth. Almost all life on earth is a process of using the light and heat energy of the sun. Solar energy can help us meet our energy needs. For example, it has been used for cooking, drying, heating and cooling buildings, generating electricity, and powering satellites and vehicles.
