1. Inexhaustible and Renewable Energy Resources

2. ….and coal, and natural gas!

3. Inexhaustible Energy –Sun –Wind –Water –Geothermal Renewable Energy –Biomass –Wood –Alcohol –Garbage

4. Energy from the Sun Pros –No Pollution, except in the manufacturing –Very efficient –Installation is more cost effective than laying high voltage wires –Very quiet

5. Energy from the Sun Cons –Initial installation is expensive –Can only generate electricity during daylight hours –Can be affected by weather

7. Energy from Wind Pros –No pollution –Little harm to the environment –Produces no waste –Take up little space

8. Energy from Wind Cons –Initial construction is expensive –Noise –Wind can be inconsistent –Birds?? = Misconception

9. Energy from Wind http://www.youtube.com/watch?v=niZ_cvu9F ts http://www.youtube.com/watch?v=niZ_cvu9F ts According to a recent report posted by the DOE’s National Renewable Energy Lab (NREL), renewables can contribute 80% of American electricity by the year 2050. Much of it will be provided by wind power installations.

10. The fact is…. There is no perfect energy source. Each and every one has its own advantages and compromises. It is a matter of weighing those advantages against the compromises, the pros against the cons, and making decisions based on what is best for our planet and the future.
