What is Energy?

• Energy is the ability to do work.

By Mrs. Deringer
3
Where does Energy Come From?
Almost all energy, comes from the Sun.
The Sun warms our planet and makes plants grow.
By Mrs. S. Deringer
4
Plants make their own Energy.

• Plants dont need to go to the supermarket to get
  their food. They can make their own food through
  a process known as photosynthesis.

By Mrs. Deringer
5
Where do we get our energy from?
You get your energy from eating plants,
or by eating other animals like
which have fed off plants.
By Mrs. Deringer
6
We also need energy to . . .

What are fossil fuels?

• Fossil fuels were made millions of years ago from
  plant life and microscopic organisms remains.
  The three primary fossil fuels are . . . . .

petroleum (oil)
Natural Gas
Coal
8
Making Electricity
This high pressure steam is used to spin huge
turbines which turn, generators.
You can use fossil fuels to make electricity.
Each can be burned to heat water. To create
steam at really high pressure.

COAL

Natural Gas
Long, long time ago, the plants in the sea died
and were buried under the sand.
After millions of years, believe it or not, with
pressure and heat, they turned into natural gas
and petroleum.
Heating Fuel
11
Oil
When these microscopic organisms died they took
the stored suns energy to their grave. .
These organisms became crude oil or petroleum.

Petrochemicals are made from witches..
Just kidding . . . . . .
By Mrs. Deringer
13
Petrochemicals are products made from fossil
fuels, mainly oil.
Man-made rubber
WAX
cosmetics
medicines

How we use fossil fuels to make electricity.
burn fossil fuels to - heat up water - water
turns to steam - steam spins the turbine (fan
blades) - turbine spins the generator (magnet) -
produces electricity.

Pollution

• All this burning of fossil fuels though, creates
  lots and lots of pollution. Causing Global
  warming. Click here to find out more about the
  dangers of global warming.

Soon we will run out of fossil fuels. So we need
to find renewable energy resources. Renewable
resources will be here forever.

Renewable Resources

• It is up to us to find other ways to power our
  vehicles and heat our homes.
• Renewable resources are natural resources that we
  will never run out of.

Solar Energy
Solar energy used to - heat up water - water
turns to steam - steam spins the turbine (fan
blades) - turbine spins the generator (magnet) -
produces electricity.

Wind Power

• WIND energy is used to -
• spins the turbine (fan blades) -
• turbine spins the generator (magnet) -
• produces electricity.

Hydroelectric

• Rushing water spins the turbine (fan blades) -
• turbine spins the generator (magnet) -
• produces electricity.

Geothermal
Heat from the earth is used to - heat up water
- water turns to steam - steam spins the
turbine (fan blades) - turbine spins the
generator (magnet) - produces electricity.

Biomass
burn biomass (plant and animal wastes, wood
chips, corn stalks) to heat up water - water
turns to steam - steam spins the turbine (fan
blades) - turbine spins the generator (magnet) -
produces electricity.
