Light Energy: energy in the form of light

Thermal Energy: energy in the form of heat

Sound Energy: energy caused by vibrations

Kinetic Energy: energy that implies movement

Solar Energy: energy coming from the sun

Chemical Energy: energy in the components of certain substances

Nuclear Energy: energy produced by the atoms of elements like uranium

Renewable sources of energy are natural resources that nature replaces automatically.

They are unlimited.

Non-renewable Energy

Non-renewable sources of energy are limited because nature doesn’t replace them.

They also cause pollution.
