Energy Resources Notes
2
Nonrenewable resources

• A natural resource that is not replaced as it is
  used
• May take millions of years to form
• Includes oil, coal, natural gas, and nuclear
  energy

3
Oil

• A type of fossil fuel that is a thick black
  liquid
• Formed millions of years ago
• Most is found underground

4
Coal

• A type of fossil fuel that is in solid form
• Been used for thousands of years
• Used to fuel electric power plants
• Used to burn for heat.

5
Natural Gas

• A type of fossil fuel
• A mixture of methane and other gases
• Found underground

6
Nuclear Energy

• Energy converted during nuclear reactions
• Comes from energy stored in the nucleus of atoms

7
Renewable Resources

• A source that is naturally replaced in a short
  amount of time or through a cycle
• Examples biomass, hydropower, and hydrogen

8
Biomass

• Living or formerly living material
• Can be made into fuel

9
Hydropower

• Power that is produced by flowing water moving
  over a waterfall or dam
• The most widely used source of renewable energy

10
Hydrogen Gas

• It is obtained from water breaking the H O
  bonds.
• A fuel that burns cleanly, with water as the
  byproduct

11
Perpetual (Inexhaustible) Resources

• A resource that exists in such a large supply
  that it is considered limitless
• Includes solar power, wind power, and geothermal
  energy

12
Solar Power

• Energy from the sun
• The source of most renewable energy sources
• Does not cause pollution

13
Wind Power

• Used to turn a turbine and generate electricity
• Fastest-growing energy source
• Does not cause pollution

14
Geothermal Energy

• Occurs when magma heats underground water
• Steam and hot water are used to generate
  electricity
