Is thermal energy renewable or nonrenewable?

i have a science project and we need to know whether themal energy is renewable or nonrenewable. Can someone please answer my question?

for a science project i have to make a wind mill or wind turbine ( a small one no taller than a foot long) and then i have to measure which shape of the blade creates the most amps..how should i connect it to an amp meter and where can i get materials to make one?
how should i get the wind turbine to connect to the generator and the meter..do u know anywhere to buy pre made small windmilll/windturbines to hook up to generators

My friend and i are working on a science project and we don't know what websites to go to about windmill energy sooo we need help with finding 3 positive things about the windmills.
Thanks!

how do you create a small wind turbine?

i need to know how for a science project and i need to have it light up a night light sized bulb

i need examples of renewable energy resources for a science project. it is due in wed 3rd dec and i need the examples because i am writing a letter explaining what you could use instead of non-renewable energy resources and i need to write down all of them. please could you help peoples, 10 points if you do. and please can i not have any negative answers about looking it up, because it doesn't give me the full works if you know what im saying.
