Renewable and Non- Renewable Energy
Let’s Watch a video

Focus Questions
What did you learn from the video?
�In your own words create a definition for
renewable and non-renewable energy?
�Give two examples of each energy source.
What is Renewable Energy?
Renewable energy is energy that is collected
from renewable resources. They can be
replenished in a very short period and they
never run out. These energy sources can
neither be created or destroyed.
What is Non-Renewable Energy?
Non renewable energy is
a source of energy that will eventually run
out. They cannot be replaced once they
have been used. It takes thousands of years
to form and we use them at such a fast rate
that there is not enough time for them to be
replaced.
What is Renewable Energy? Cont’d
Examples
� Solar
� hydro
� Wind
� Tidal
� Geothermal Power
Solar Energy- this is harnessing
the energy from the sun to
produce electricity. Solar cell
can be used to convert the sun’s
energy into electricity.

� Wind is plentiful and a clean source of
energy. A collection of wind mills is called
a wind farm. These farms produce noise so
is mostly away from large populations. A
wind mill is not suitable for every position
and is depend on wind speeds or
availability.
Geothermal energyuses the heat inside the Earth to
produce steam
that drives turbines to produce
electricity.
BIOMASS ENERGY -this involves the
conversion of solid fuel made from
plant materials. It involves the
burning of organic material to
produce electricity however wood
is not used.
