i’ve seen a series of commercials by a group promoting green energy and environmental interests, they featured a little girl, one time at a pond, talking about wind energy i believe, one time at the beach talking about solar energy, and the third one i don’t remember. I’m currently student teaching a 4th grade class, and i think that these commercials would really help open childrens eyes to simple things that can be done to save the earth. the company had a website that the commercials were viewable on, but i cannot remember it. any ideas what i’m talking about?

Hello,
I know little on solar power for the home. I understand that it is possible to convert power to chemical form then use it as electricity. My question is, what elements are involved and how is the sizing being done?
I need the power design to power lights (say 10), TV and radio.

I’m trying to find information on solar panels or wind turbines that would be able to power a whole neighborhood, along with how much it would cost.
