Energy

Brainstorm:
In your science
notebook brainstorm a
list of all the ways that
humans can get energy
and where this energy
comes from.
Fossil FuelsCoal, Oil, &
Natural Gas
Coal
•These
are called “Fossil
Fuels” because they are
formed from the
fossilized remains of
prehistoric plants and
animals.
•These
take millions of
years to form.
•They
•Most
are nonrenewable.
of the USA uses
Fossil Fuels for energy.
Oil
Natural Gas
Coal
•This
is the most
abundant fossil fuel
in the United States.
•It is a hard black
rock-like substance
formed from dead
plants that were
subjected to extreme
heart and pressure.
•When coal is
burned for energy it
releases SOx which
forms acid rain.
Oil &
Petroleum
•Oil
was formed from
the remains of tiny sea
animals and plants
that formed millions
of years ago.
•Oil has to be refined
in order to be used.
Example- gasoline
•Oil can be harmful if
it is spilled and as it is
burned.
•Most oil is used for
transportation.
Natural Gas
Natural gas is formed
from the remains of tiny
plants and animals that
died millions of years
ago.
It is found more than
6,000 feet under the
Earth’s surface.
When burned, it
produces little pollution
and is considered the
most environmentally
friendly fossil fuel.
Used by a lot of people
in the US for heating.

Brainstorm:
In your science
notebook brainstorm a
list of things that are
nonrenewable and a list
of things that are
renewable.
RENEWABLE
•These won’t run out.
•Example- Winds will keep on
blowing, whether we use the
energy or not.
•Most Often Used: Biomass,
Wind, Water, Geothermal, and
Solar.
NONRENEWABLE
•These will run out eventually.
•Example- When we've extracted
all the Earth's oil, there isn't any
more.
•Most Often Used: Oil, Coal,
Natural Gas, Uranium
Nuclear
Energy
•Nuclear
power is
generated using Uranium,
which is a metal mined in
various parts of the
world.
•Nuclear power produces
around 11% of the world's
energy needs, and
produces huge amounts
of energy from small
amounts of fuel, without
the pollution that you'd
get from burning fossil
fuels.

Hydropower
•This
is energy that
comes from moving
water.
•Usually works
when a dam is built
and water moves
through “turbines”.
•No air pollution is
created but there are
still negative
impacts to the
environment.
