4. NUCLEAR ENERGY
Nuclear fission uses
uranium to create
energy.
Nuclear energy is a
nonrenewable
resource because
once the uranium is
used, it is gone!
5. Fossil Fuels
Fossil fuels take millions of
years to form. They are the
product of the fossilized
remains of dead plants and
animals that have been
exposed to the heat and
pressure deep within the
earth’s crust. There are many
types of fossil fuels, such as
petroleum (gasoline), natural
gas, and coal.
6. 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.
10. SOLAR
The sun’s rays are used
for energy by organisms
that undergo
photosynthesis. Nearly
every organism on the
planet gets energy through
photosynthesis, directly or
indirectly. There are also
ways that people can
utilize the energy that the
sun provides.
11. GEOTHERMAL
Geothermal energy is
thermal energy
generated and stored
in the Earth.
Earth's geothermal
energy originates from
the original formation
of the planet, from
volcanic activity, and
from solar energy
absorbed at the
surface.
12. WIND
Wind is caused by the uneven heating of
the atmosphere.
Some areas of the world, such as costal
regions, have more wind than others
because the terrain of the area is
relatively flat and has few obstacles to
block the wind from blowing.
The wind blows naturally – it is not caused
by human activity, and it cannot be used
up.
13. BIOMASS
Biomass, a renewable energy source, is
biological material from living, or recently
living organisms, such as
wood, waste, (hydrogen) gas, and alcohol
fuels.
Biomass energy is derived from five
distinct energy sources:
garbage, wood, waste, landfill gases, and
14. HYDROELECTRIC
Hydroelectricity is the
term referring to electricity
generated by hydropower ;
the production of electrical
power through the use of the
gravitational force of falling
or flowing water.
It is the most widely used
form of renewable energy.
