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.
