The energy resources
used to generate
electricity can be divided
into two categories:

Nonrenewable resources
cannot be increased. We can
make these supplies last
longer by using them wisely,
but when they are gone we
will not have any more.

The majority of electricity
used in the world is
generated at power plants
that burn fossil fuels to heat
water and make steam. The
steam is highly pressurized
and directed at turbine ['t?ba?n]
blades to make them spin.

The three forms of fossil fuels are
oil, and
natural gas.

They are known as fossil fuels
because they were formed from
the fossilized remains of animals
or plants that lived long ago.

Nuclear Power
Nuclear power plants use
the heat from splitting
atoms to convert water
into the steam that turns

Renewable Resources
Renewable energy resources
can be replenished in a short
period of time, so they will
never be all used up. Energy
companies all over the world
are using renewable
resources more and more to
generate electricity.


Biomass is organic matter, such
as agricultural wastes, and wood
chips and bark left over when
lumber is produced. Biomass can
be burned to heat water to make
steam, which turns a turbine to
make electricity. It can also be
converted into a gas, which can
be burned to do the same thing.

Geothermal Energy
The word
comes from the
Greek words geo,
for earth, and
therme, for heat.
So geothermal
means "earth

Geothermal energy
is steam (or hot
water that has been
converted to steam)
from deep inside
the earth.

Hydrogen is a colorless,
odorless gas. Hydrogen can be
converted into electricity
through a chemical reaction in
a device called a fuel cell.
Converting hydrogen into
electricity produces no
pollution—only water and heat.


Hydroelectric plants use the
power of falling water to turn the
turbines that help generate

Wave power
The energy of the ocean's
waves and tides can also be
used to generate electricity
with dams that force ocean
water through turbines.
This is called tidal energy,
or wave power.

The world's first wave power
station is on the Scottish
island of Islay. It generates
enough electricity for about
400 homes.

Solar Energy
Solar energy is generated
without a turbine or

Special panels of solar
cells, or modules, can
capture sunlight and
convert it directly into

Wind Power
Wind power is renewable energy
that uses the force of the wind
to spin turbines. These
spinning turbines generate

A very large wind farm can
generate enough electricity for
all the homes in a city of about
one million people.
