There are two types of energy used today, renewable and nonrenewable.
Every time we buy or use a product that is made from nonrenewable resources, that is a tiny piece of our planet that can never be replaced.
Fossil fuels, on the other hand, are nonrenewable.
Wind powered generators create energy that can be used instead of energy that comes from nonrenewable resources.
Nonrenewable energy is produced by the burning, splitting or destroying of another resource.
