1 Energy Resources Renewable and Non Renewable

2 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

3 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

4 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

5 Nuclear Energy Energy comes from radioactive elements Generates thermal (heat) energy by boiling water to produce steam

6 Solar Energy sunlight is changed into electric or thermal energy through solar cells. cannot be used up Renewable Resources

7 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

8 Wind Energy Kinetic / Mechanical Energy from passing winds change to electrical energy Winds turn turbines & turbines give off electrical energy through a generator

9 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

10 BioMass – burning of orgnanic matter to release usable energy Plants use and store energy from the sun through photosynthesis
