Earth day presentation
Annotated Bibliography
http://en.wikipedia.org/wiki/Solar_energy
This source was one of my main information centers. It has almost everything you could want to know on one page of data from economics to the functions of a solar panel. This was one of my best sources.
http://www.howstuffworks.com/solar-cell.htm
This explained indepthly how a solar panel works. It basically said that there are bunches of little solar cells on a solar panel that all collect energy. This energy is then fed back through an electrical wire.

This basically explains that solar power is the power from the sun(witch can supply our energy needs 8,500 times over). It said our main problem was to harness it efficiently.

This listed all the other ways to use solar power, like passive solar, and gave a basic description of solar power in general. This site was also very helpful because it gave some new information that i didn't know.

I learned that you can save over half on your electricity bill.And is this just using solar panels. Or is this with many different types of solar energy. And I can see that If everyone has at least one solar panel that could help our current economy. I found it interesting when you said that they could break your bill into half. I never really even knew how the solar panels worked. What I want to know more about is where can you get these.
3 I learned that the energy from the sun could replace our energy by 8500 times. It really shows that people dont care and dont even think of using solar power because we dont use that energy. It is really expensive to have polar power. About $20,000 a panel. It cost $10-$12 per watt of energy. That is crazy expensive.
2 I found it interesting that you think the whole world would go into a huge depression. I dont think that would happen but it is interesting what you think about it. Also i thought it was cool how you related to yourself you said you have a solar pannel and you could relate on how expensive.
1 I would like to learn more on how we can use that energy and how we can make it cheaper to go all solar power energy.
