Renewable/Nonrenewable Energy Resources
A type of energy resource that takes millions of years to form and is used up faster than it can be replaced
Nonrenewable Energy Resource
(also would accept fossil fuels)

energy transmitted in waves or a stream of particles; this type of heat transfer can travel through space and other types of matter.
Radiation
the energy an object has due to its motion
Kinetic Energy
Energy resources that can be replaced in a relatively short amount of time and produce very little pollution
