Energy Resources 1-5-12

Notes

Energy Resource- A natural resource that people

can turn into other forms of energy in order to do work.

Where do we get our energy

resources?

Nonrenewable Resource

•Cannot be replaced after they are used

• Takes millions of years to reform or be replaced

Can you name the types of

nonrenewable resources?

Fossil FuelsFormed from the buried remains of

plants and animals that lived millions of years ago.

Why are they called “Fossil” Fuels?

+ =

Types of Fossil Fuels•Coal- formed from the

remains of plants in prehistoric seas and

lakes

Oil (Petroleum)a smelly, yellow-to-black liquid

formed from plants and animals

•Natural Gas- gas made from prehistoric plants and animals that

compressed (squeezed) deep undergroundNot to be confused with gasoline for cars!

Nuclear Energy-Made from using radioactive elements

like uranium. The energy is given off when the nucleus

of an atom splits.

Renewable Resources

Used and replaced over a short period of time

Wind Energy-Wind is caused by the uneven

heating of the Earth. -The wind moves the blades that are

attached to a generator.

The energy in the generator is changed into electricity.

The energy travels from the generator into power lines.

Solar Energy- inexhaustible (won’t run out)

Energy from Water-Falling water travels through a dam and

spins a turbine (machine). The turbine is connected to a generator

and produces electricity

Geothermal Energy(Geo – “the Earth”)(Thermal- “ heat”)

Areas called hot spots release heat that can be used to make electricity.

Biomass-Plants, wood and garbage can

be burned to release energy.
