

A place where energy originates (comes)
from.
Energy transformations can be traced
back to a primary source of energy or
ENERGY RESOURCE.
Energy resources generate power for
objects used in our everyday lives, i.e.
electricity.
Sources that can not be replaced
Fossil Fuels
Nuclear
COAL
OIL
NATURAL
GAS
Burning fossil
fuels creates
steam which
can turn a
generator.
View an animation of how fossil fuels
release steam and turn a generator to
produce electricity
NUCLEAR
Energy is release when atoms are
combined or separated.

Biomass
Energy from things that once were
alive. Burning biomass creates
steam which can turn a generator.
Geothermal
Solar
Hydroelectric power
(Water)
Wind
GEOTHERMAL
Heat from inside Earth creates
steam which can turn a generator.
Energy from the sun that is converted (changed)
into thermal or electrical energy. The energy can
be stored in solar cells.

sources of energy. Explain where they
come from. Try to name as many as you
can from memory without peaking in
your notes ;)

Advantages
Disadvantages
•Difficult to generate LARGE
•Renewable energy is derived from quantities of electricity
sources that never run out such •Renewable energy often relies on
as the sun, wind, water and plant
material.
•Using renewable energy reduces
our dependence on other
energy sources that contribute to
climate change and can help make
a big difference to the energy
efficiency of your housing or
buildings.
•Little to NO pollution
the weather for its source of power.
Hydro generators need rain to fill
dams to supply flowing water. Wind
turbines need wind to turn the
blades, and solar collectors need
clear skies and sunshine to collect
heat and make electricity. This can
be unpredictable and
inconsistent.
•The current cost of renewable
energy technology is also more
expensive than fossil fuel.
