This document discusses several of the world's non-renewable natural resources including oil, coal, uranium, and provides details on how they are formed and used. It also discusses renewable energy sources like nuclear power, wind energy, and hydroelectric power. Oil and coal are fossil fuels formed from ancient marine life millions of years ago. Uranium is mined for nuclear fuel and weapons. Nuclear power creates electricity through controlled fission, while wind turbines and hydroelectric dams convert kinetic energy from the wind and moving water into electricity.
4. Oil
Oil is a nonrenewable energy source.
Oil is the most used resource next to the Sun.
When oil is burnt is gives off a gas that is then
discarded into the atmosphere.

6. More Oil
Most oil is found mainly in the middle east,
because around 80 million years ago,
climate change caused the ocean currents
to stop, and the Tethys sea (AKA the
Mediterranean) stopped flowing.
Then all the marine life died, poisoned by
hydrogen sulphide, and sank to the bottom.

8. Even More Oil
With the northern movement of the African
plate, and the shrinking of the Tethys sea, this
clump of decomposing material shifted east.
The largest oil and gas reserves are in Central
Asia and Siberia.

10. Coal
Coal is a non renewable energy source.
Coal is mined out from the ground.
Coal is the third most used energy source next to
the sun.
When coal runs out, we wont have coal grills, coal
pencils for shading art, coal filters for making
clean water, and much much more things that
need coal.

12. More Coal
Coal is burnt to heat water, and the steam produced turns a
turbine.
The turbine is connected to a generator and the generator
generates electricity which goes through wires and
transformers until it gets to your home.
13.
14. Uranium
Uranium is a mined ore that can be used as
nuclear fuel for nuclear power reactors, material
for armor and armor piercing bullets, and also
nuclear weapons.
When uranium is mined, the miners need
protection from natural radiation, that the
exposed uranium ore causes.

16. Nuclear Power
Pressured water nuclear reactors is 1 type of a
reactor that creates nuclear power by pressurizing
water and sending it through a pipe to cool the
very hot nuclear infused water and turn it into
steam which turns a turbine generator and creates
energy.
Nuclear reactors create only a coke bottle of
pollution each year.
The U.S. creates about 806 billion kilowatt hours
of electricity from nuclear energy in 2010.
19. More Nuclear Power
When a nuclear reactor is over heated or suddenly
cooled, it will either crack or melt the core.
While the nuclear fusion process is going on the core is
about 1,112˚F. Lava is about 1,200˚F.
20. Wind Energy
The term wind energy describes the process in
which the wind is used to generate electricity.
Wind turbines convert the kinetic energy in the
wind into mechanical power. This power can be
used for tasks (like grinding grain or pumping
water) or a generator can convert this power
into electricity to power homes, businesses,
schools, and the like.
21. More Wind Energy
Wind turbines, turn in the moving air and power a
generator that makes electricity. Instead of using
electricity to make wind, like a fan, wind turbines use wind
to make electricity. The wind turns the blades, which spin
a shaft, which connects to a generator and makes
electricity.
22. Hydro
Hydropower is electricity generated using the energy of
moving water. Rain or melted snow, usually originating in
hills and mountains, create streams and rivers that run to
the ocean. The energy of that moving water can be very
strong.
This energy has been used for years. Farmers since the
ancient Greeks have used water wheels to grind wheat
into flour. Placed in a river, a water wheel picks up flowing
water in buckets located around the wheel. The kinetic
energy of the flowing river turns the wheel and is
converted into energy that runs the mill.
