fossill fuel : a nonrenewable energy resource formed from the remains of organisms that lived long ago
electric generator : a device that converts mechanical energy into electrical energy
petroleum : a liquid mixture of complex hydrocarbon compounds
oil reserves : oil deposits that are discovered and are in commercial production
nuclear energy : the energy released by a fission or fusion reaction
nuclear fission : the process by which the nucleus of a heavy atom splits into two or more fragments; releases neutrons and energy
nuclear fusion : the process by which nuclei of small atoms combine to form a new, more massive nucleus; releases energy
