1. Energy Resources
A natural resource that can be
converted by humans into forms of
energy in order to do useful work!

2. Nonrenewable
• These are energy resources that cannot be
replaced after they have been used or need
thousands to millions of years to be
replaced.
• Like What?

3. Fossil Fuels
• Fossil fuels are energy resources that formed from
the buried remains of plants and animals that lived
millions of years ago.
• The plants stored energy from the sun during
photosynthesis. (CO2 + H2O  Glucose + O2)
(in sunlight )
• Animals stored this same energy by eating the
plants.
• So, fossil fuels are concentrated forms of the sun’s
energy!

4. Fossil Fuels

5. The higher the carbon content, the cleaner the fuel
burns.

10. Recycling just one aluminum
can saves enough energy to run
a television set for four hours!

11. The pioneers who settled the American West
often dug wells to find water.
Occasionally, they were disappointed because
they struck oil, for which they had no use!

12. Electrical Energy from Fossil
Fuels
• Burning fossil fuels are the primary source
of energy in the United States.
• K.E. electrical energy by an electric
generator.

13. In 1882, Thomas Edison built the first
electrical generating station designed to
provide electrical energy to homes and
businesses in Manhattan.

14. Nuclear Energy
• Nuclear power plants generate thermal
energy that boils water to produce steam.
The steam turns a turbine, which rotates a
generator that converts K.E.  electrical
energy.

15. Nuclear Fission

16. Of all the energy used by a standard light bulb, only
one-tenth is converted to light energy. The rest is
thermal energy. That’s why light bulbs are soooooo
hot after they have been on for a while.

17. Renewable Energy Resources
An energy resource that can be used
and replaced in nature in a short
period of time.

18. Solar Energy

19. Water Energy

20. Wind Energy

21. Geothermal Energy

22. Biomass
