Transcript NONRENEWABLE AND RENEWABLE RESOURCES

Aim: What are
renewable and nonrenewable resources?
Do Now:
Where do we get our energy from?
Spot the energy resources
How many different energy resources are
part of this scene?
Turn and Talk
What do you think
nonrenewable
resources are?
Break it down...
Nonrenewable?

NONRENEWABLE RESOURCES
A nonrenewable resource is a natural
resource that cannot be re-made or
re-grown at a scale comparable to its
consumption (use).
• Non-Renewable Resources are
Finite.
• Finite- They are limited in quantity
and will finish.
Examples
• Nuclear Energy
• Fossil Fuels (Coal,
Petroleum, Gas)
NUCLEAR ENERGY
Nuclear fission uses
uranium to create
energy.
Nuclear energy is a
nonrenewable
resource because once
the uranium is used, it
is gone!
COAL, PETROLEUM, AND GAS
Coal, petroleum, and
natural gas are
considered
nonrenewable because
they can not be
replenished in a short
period of time. These
are called fossil fuels.
HOW IS COAL MADE ???
What waste do fossil fuels produce?
• Burning fossil
fuels creates
waste products
that can act as
pollutants and
harm the
environment.
• Carbon dioxide –a
greenhouse
produced by
burning fossil fuels.
• Sulfur dioxide and
nitric oxides –
contribute to acid
rain.
Talk and Turn
If nonrenewable
resources are resources
that cannot be re-made
at a scale comparable
to its consumption,
what are renewable
resources?
RENEWABLE RESOURCES
Renewable resources are
natural resources that can be
replenished in a short period
of time.
● Solar ● Geothermal
● Wind ● Water
SOLAR
Energy from the
sun is renewable
because the sun is
always available.
GEOTHERMAL
Energy from
Earth’s heat.
Why is energy
from the heat of
the Earth
renewable?
WIND
Energy from
the wind.
Why is energy
from the wind
renewable?
WATER or HYDROELECTRIC
Energy from the
flow of water.
Why is energy of
flowing water
renewable?
Activity
• With your partner try to complete the
advantage/disadvantage page for the
listed energy sources.
• We will review together.
SUMMARY
What are the
differences
between
nonrenewable and
renewable
resources?
What do renewable and non-renewable mean?
Energy resources can be classified into two
groups.
Renewable
Renewable energy resources
can be replaced or
regenerated and will never run
out (at least not for a very long
time).
Examples: wind and solar.
Non-renewable
Non-renewable energy
resources will
eventually run out –
once used they cannot
be used again.
Examples: coal and oil.
