This document defines and provides examples of different types of renewable energy sources, including solar, wind, tidal, hydroelectric, biomass, and geothermal energy. It explains that renewable energy comes from resources that replenish themselves naturally, such as sunlight, wind, rain, tides, waves and geothermal heat. For each type of renewable energy, it provides a brief description of how it works and can be used to generate electricity or power.

3. Renewable energy is a socially and
politically defined category of energy
sources. Renewable energy is generally
defined as energy that comes from
resources which are continually
replenished on a human timescale such
as sunlight, wind, rain, tides, waves and
geothermal heat.

4. Solar energy means energy from the sun.
We can capture some of the sun’s
energy and use it to heat buildings ,
provide light and generate electricity.

5. Humans have used wind energy to power
machinery in windmills for hundreds of
years. Today, electricity companies are
building wind farms which use giant
machines called wind turbines to make
electricity for homes , schools and
factories.

6. Everyday the tide at the seaside goes in
and out – twice. This rising and falling of
the sea is caused by the pull of the
moon. We can use this powerful flow of
water to generate electricity.

7. Hydro-energy means energy from moving
water. It is one of the oldest forms of
power. Watermills have been used to
grind corn for hundreds of years. Today,
electricity can be generated by building
dams, which force water to turn
machinery.

8. Biomass is a renewable energy source because
the energy it contains comes from the sun.
Through the process of photosynthesis in plants
captures the sun's energy by converting
carbon dioxide from the air and water from the
ground into carbohydrates. When these
carbohydrates are burned, they turn back into
carbon dioxide and water and release the
sun's energy they contain. In this way, biomass
functions as a sort of natural battery for storing
solar energy. As long as biomass is produced
sustainably—with only as much used as is
grown—the battery will last indefinitely.

9. Coal miners know that the deeper you dig
the hotter it gets. This is because of the
heat at the earths core. We call the
earths natural heat geothermal energy.
This can be used to heat buildings or
generate electricity.
