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
Plants make their own Energy.

By Mrs. Deringer
Plants don’t need to go to the
supermarket to get their food.
They can make their own food
through a process known as
photosynthesis.
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.

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 . . . . .
Natural Gas Coal
petroleum
(oil)
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.

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.
Oil
When these microscopic
organisms died they took the
stored sun’s energy to their
grave. .

By Mrs. Deringer
Petrochemicals are products
made from fossil fuels, mainly
oil.

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.
