Energy Ugrade links and $?

Question

This is for a science project so it needs to be answered today, and I need any sources.

In fact, that's kinda what I'm asking for.

If you know a good website for any of these following things, involving how much energy they use, their cost, and if possible, comparing this to other products, please let me know.

Solar Panels

Air Conditioners

Electrical Cars

Geothermal heaters

also, if you know a site that gives the total usage of natural gas and gasoline in a country, that would be nice.
