1. Electricity— high demand product for daily lives
Energy
Electricity— high demand product for daily lives
Electric generator---device that converts other forms of energy into electricity

2. Fossil Fuels
coal, oil, natural gas---remains of dead organisms from millions of years ago
use to make electricity or as a fuel source for plane, trains and automobiles

3. OIL and NATURAL GAS (Methane)
Made from the decayed remains of sea creatures which died millions of years ago
Even though it was not made from dead plants or animals, nuclear fuel is considered to be a fossil fuel because it comes from the ground and is running out.

4. These fuels were dug out of the ground
These fuels were dug out of the ground. They had taken millions of years to make and so are called FOSSIL FUELS and are NON-RENEWABLE.
COAL:
Made from the remains of plants which died millions of years ago

6. Fossil Fuels
Finite resource— only so much on the planet
Nonrenewable resource —only can be used once

7. Nuclear Energy
energy from the nucleus of an atom
Nuclear Fission—subatomic bonds are broken apart— huge amount of energy is released

9. Advantage for Nuclear Power
1.) High in energy
2.) Well run reactor— low maintenance and low fuel needs
3.) No CO2 production

10. Safety Concerns
1.) Radioactive products/accidents
1957— Chernobyl Russia
Three Mile Island PA
Fukushima Japan

11. Nuclear Fusion
lightweight atomic nuclei combine — releases energy
this energy powers stars
technically difficult to do because you need high temps 100,000,000°C
Not yet recreated in a laboratory

13. Sustainable Energy Future
1.) Conservation – use less energy —turn thermostat down, walk, bike, carpool, energy efficient products

14. 2.) Solar Energy—from the sun
clean, safe, renewable
3 types
passive solar
active solar
solar cells

15. Passive solar heating
sunlight heats buildings directly w/o pump or fan--- energy efficient windows facing south so it can get as much sun during the day as possible

16. Active solar heating
series of collectors that absorb solar energy and converts it to heat

17. Solar cells
converts solar energy into electricity

18. WIND
Its caused by solar energy —the sun heats the earth unevenly causing temperature difference causing air to move to equalize temperature

19. Wind-generator
captures the winds energy with the use of a turbine converts it to electricity
Negatives: noise,
not attractive,
migratory birds
and bats

20. Hydroelectricity
the water moves a turbine to create electricity
need height —so use a dam
renewable, clean, no waste
Negatives--- dam changes habitats blocks migration routes of some fish.

22. Geothermal
uses the heat from the earth to drive electric generators—similar to fossil fuels
renewable, clean, no waste
Negative--- only can be in certain locations

23. Iceland

24. Biomass
1.) organic matter from plants or plant products---ex: wood
renewable, save fossil fuel
negative: CO2, smoke

26. 2.) Waste to energy
pulp/paper industry
sugar cane industry
Both use wastes to generate electricity

27. 3.) Liquid fuels
ex: methanol—from wood
ethanol--- from corn, fruit, agriculture waste
“Cleaner” than gasoline and diesel
Negative— CO2 emissions, Can use more resources depending on source materials

28. Hydrogen
clean burning gas from the splitting of water
Non pollution---”waste” is water
Negative— storage-need high pressure or chilling method to hold enough for use in a car
