2. Where do you use energy?
With your partner, right down as many activities
as you can that consume energy.
All groups will need to give an answer.

4. Where do you use energy?
The truth is, we use
energy for just about
everything we do.
If we aren’t directly using
energy (turning on a light,
charging our phones,
watching TV), then energy
is being used indirectly.
5. Industry
Energy is used during every step of the
industrial process: obtaining resources,
manufacturing goods, and transporting goods.
8. Fossil Fuels refer to the material that is is
formed from decomposed prehistoric
organic matter, such as dinosaur bones
Where Does Energy Come
From?
9. The most common forms of fossil fuels is
petrol (oil/gasoline) and natural gas
Where Does Energy Come
From?
10. Fossil Fuels
● Coal
o Declining in use
● Natural Gas
o Used primarily for heating in
homes
● Gasoline
o Most common form of fossil
fuel
11. Fossil Fuels
Why are fossil fuels great?
● Fossil fuels are cheap (relatively) and easy
to use. All you really have to do is burn the
fuel and it creates energy.
● Remember, the basic idea is that heat is
energy
12. Fossil Fuels
Why are fossil fuels not great?
● Non-renewable (finite): they will run out
o Some estimates say some forms of fossil fuels will
run out in our lifetime
● Cause of conflict
o Small supply = fighting
o Wars in the Middle East
15. Nuclear Energy
● Nuclear energy is
much cleaner and
longer lasting than
fossil fuels
● But it is very
expensive and very
dangerous if not used
properly
● Creates lots of waste
19. Hydroelectric
● Hydroelectric
energy is one of
the most efficient
renewable sources
of energy today
● Dams around the
world create a non-
stop supply of
electricity
20. Hydroelectric
The downside to hydroelectric energy is that it is very
expensive and difficult to build and has a large impact on
the environment (not necessarily negative)
23. Renewable
● Positives
o These sources of energy are much more
environmentally friendly that non-renewables
o They will last much longer
● Downsides
o They are much more expensive
o They usually take up a lot of space
o Do not work everywhere in the world
o No way to store this electricity
