2. Energy is the ability to do work.
What is energy?
Energy is the ability to do work.
Then what is work?
Force and movement.

3. Traditional energy-resources that cannot be replenished
Ex.) Oil,Wood, Natural gas, Nuclear fission, Coal
Pros: Cheap and reliable
Cons: Contribute to global
Warming, non-renewable.

4. Pros: relatively inexpensive, Abundant supply, has a high load factor
Coal
Cons: Nonrenewable, coal ash problem and disposal problem
Pros: relatively inexpensive, Abundant supply, has a high load factor

5. Nuclear Fission
-splitting the atom and using uranium to harvest energy
Pros: Very low fuel cost, virtually unlimited amount of fuel, clean energy
Cons: could produce net negative amount of energy, power plants$$$, requires extremely high temperatures.

6. Natural Gas-flammable gas, mainly consisting largely of methane and other hydrocarbons, occurring naturally underground.
Pros:
-Cleaned of all the fossil fuels.
-End use appliances already widespread.
-Can be used as an automotive fuel.
Cons:
-Emits carbon dioxide when burned.
-Explosive,potentially dangerous.
-Nonrenewable fuel,supply cannot be replaced for millennia.

7. Oil-a natural gas derived from petroleum
Cons: Release greenhouses when oil is burnt, Nonrenewable energy, oil spills can cause environmental disasters
Pros: High energy density, Easy to produce and refine, Constant power source

8. Wood- fuel can be used for cooking and heating, and occasionally for fueling steam engines and steam turbines.
Pros:
-cheaper
-can be grown
-less pollution
-improves forest health
Cons:
-requires more space
-Needs safe disposal
-equipment is expensive $$

9. Alternative Energy- Energy made in ways that do not deplete natural resources or harm the environment
Pros: Very useful to everyone and generates a lot of energy at once
Cons: $$$ very expensive and needs constant sunlight

10. Solar Energy-energy from the sun
Cons:
-Requires a wide area
-Energy storage is expensive
-Very expensive
- Exotic materials
Pros:
-Solar energy is renewable
-Environmentally friendly
-Reduces electricity cost

11. Wind Energy-the process in which wind is used to generate energy.
Pros:
-Wind is a green energy source
-Free
-Produces no waste product
Cons:
-Cannot work without wind
-Can be noisy
-Can kill birds

12. Hydroelectric Energy-Flowing water that is turned into energy.
Pros:
-Flexibility
-Is safe compared to nuclear energy and fossil fuels.
-Renewable and clean.
Cons:
-Can cause accidents.
-Expensive to build dams
-Cause upstream flooding

13. Geothermal Energy- energy found from hot water and hot rock found under the earth.
Pros: - Environmentally friendly compared to gas or oil.
-Little or no fuel
-Little impact on environment
Cons:
Dangerous gases come up from ground
Can't build power plants everywhere

14. Biofuel-fuel created from any living matter.
Pros:
-Fuels tend to be cheap
-Renewable
Cons:
-When burned they can create greenhouse gases.
