SOURCES OF ENERGY

2

We use energy every day. Energy is need to operate

machines, to heat and cool our homes and schools, to

cook, to provide light and to take people from place to

place.

3

THE SUN

Almost all of the energy we use comes

from the sun.

The sun is like a giant energy factory.

The easiest way to get energy from the

sun is to use its light.

4

SOLAR ENERGY

Solar energy is used to perform small

jobs.

People catch energy from the sun by

using solar cells.

5

Solar panels are used to

collect energy from the sun.

6

Fossil Fuels

Coal, oil and natural gas are fossil fuels.

Fossil fuels are formed in the earth from plants and animals that died millions of years ago.

Fossil fuels are a nonrenewable form of energy. That means that they can not be replaced once they are used.

7

COAL

Coal is an important fossil fuel.

Coal is found underground.

Coal is used to make electric power.

When coal is burned, it pollutes the air.

8

This coal is being carried from a coal

mine in a box car.

9

OIL

Oil is removed from deep within the

Earth. Workers pump oil out of the

Earth using wells.

Oil is used to make gasoline and

heating fuel.

10

Oil is being removed from the

Earth with a drill.

11

NATURAL GAS

Natural gas comes from the Earth.

Natural gas is a clean source of energy.

Natural gas can be compressed into a

liquid and moved long distances

through pipelines.

12

These pipes carry natural

gas.

13

Other Forms of Energy

Energy from water is called

Hydropower.

Falling or moving water can be used to

create energy.

14

Dams are used to create

Hydropower.

15

WIND POWER

Wind power turns windmills and moves

sailboats.

16

Windmills have been used for

hundreds of years to grind

grain and pump water.

17

CONSERVATION

Since fossil fuels are a nonrenewable source

of energy, it is important that we conserve

energy.

We can conserve energy by turning off lights

when they are not being used, walk instead of

drive if we are going short distances and

wear layers of clothes to keep warm.
