I'm planning to buy either a Wind Powered Generators, Solar Generators or a Hybrid Generator to be more "Green" & at the same time save on electric bills... I'm able to install such a generator on my home...

What are the different types of generators used to produce electricity? We were told that there are 6 types of them. Please answer, i need it ASAP! Thank you very much.

Generators are typical small ones that are usually bought at Lowes or a Home Depot. I want to hook them together to power my house.

I am doing an experiment with thermoelectric generators. I need a lot of those things but the problem is that they're just too expensive. But when it comes to thermoelectric coolers, they seem to be cheaper. Can a thermoelectric cooler be used to generate electricity?
