Moving or falling water can be used to make electricity, called hydro power. The
water turns wheels that run machines called turbines and generators. These
machines use the moving water to make electricity.
The center of the earth is made up of rock so hot that it's melted. This heat
sometimes makes underground water boil. When this hot water of steam comes up
through a crack in the earth, we call it a geyser. When the steam is used to generate
electricity,it's called geothermal energy.
The sun warms the earth and gives us light. The sun's energy can be captured and
used directly in a solar cell, or changed into steam for making electricity, heating
homes or heating water.
Wind, like the sun, is one of the oldest kinds of energy used by people. When the
wind blows against big blades on windmills, the movement of the spinning blades
can pump water or produce electricity.
Nuclear power plants run on uranium, an atomic fuel that when split gives off heat
to boil water and make steam. The steam then turns turbines which make
Fossil fuels like oil, natural gas and coal are usually found under the ground or
ocean. We must drill of dig deep into the earth to uncover them. The fuels are used
to make heat, electricity and other products like gasoline.
Now that we've found out about the energy sources of today, let's play a little
