Energy ResourcesRenewable and Non Renewable

Energy resources are natural resources that

people can turn into other forms of energy in

order to do useful work.

Non Renewable Energy Resources are resources

that cannot be replaced after they are used or

can be replaced only over thousands or millions

of years.

Renewable Resources are replaced over a short

period of time.

Energy Resources

Non Renewable Energy Resources

Fossil Fuels – Coal, Petroleum, and Natural Gas•Main source of electric energy

• Formed from the buried remains of plants and animals that lived long ago

• Generate electricity by burning fossil fuels

Nuclear Energy• Energy comes from radioactive

elements

• Generates thermal (heat) energy by boiling water to produce steam

Solar Energy •sunlight is changed into electric or thermal energy through solar cells.

•cannot be used up

Renewable Resources

Energy From Water•Kinetic / Mechanical Energy from falling water changes to electrical energy

•Falling water turns turbines & turbines give off electrical energy through a generator

Wind Energy•Kinetic / Mechanical Energy from passing winds change to electrical energy

•Winds turn turbines & turbines give off electrical energy through a generator

Geothermal Energy – Thermal Energy caused

by heating of the Earths crust

• ground water heats up and forms geysers

Powerplants put water into the ground, wait for it to heat up, water comes up as steam, steam turns generator to change mechanical energy to electrical

BioMass – burning of orgnanic matter to release usable energy• Plants use and store energy from the

sun through photosynthesis
