1. Resources
Notes

2. Renewable vs. Nonrenewable
A renewable resource is a natural resource which can replenish with the passage of time, either through biological reproduction or other naturally recurring processes.
A nonrenewable resource is a natural resource that cannot be renewed or replaced.

3. Fuel
Fuel: a substance that provides energy as a result of a chemical change.
Energy: The ability to do work.
Examples of energy provided by fuel:
Heat
Light
Electricity
Motion

4. Energy Transformation
Definition: changing from one form of energy to another
Also called:
energy conversion

5. Combustion
Fuel contains stored chemical energy which can be released by combustion or burning.
When fuels are burned, the chemical energy that is released can be used to generate other forms of energy, such as heat, light, motion and electricity.

6. Making Electricity

7. Fossil Fuels
Definition: Energy-rich compounds that are formed from the remains of organisms.
Fossil fuels are made from hydrocarbons – which are compounds containing hydrogen and carbon
Fossil Fuels = Nonrenewable energy resource
LIMITED SUPPLY!
Examples:
Coal
Oil
Natural Gas

8. Coal Definition: Solid form of fuel from plant remains. Nonrenewable
Mined from the ground
Formation of Coal:
Textbook page 161, figure 2

10. Oil Definition: Thick, black liquid fossil fuel. Also called petroleum
Nonrenewable
Refinery: a factory in which oil is heated and separated into fuels and other products.
Petrochemicals – compounds made from oil. (used to make: cosmetics, plastics, paints, medicines, etc.)

12. Natural Gas Definition: mixture of methane and other gases.
Comes from the same organisms as oil.
Less dense than oil
Produced large amount of energy – but releases less pollutants than oil or coal
HIGHLY FLAMMABLE!
