Is electricity created at power plants?
No. Technically speaking, electricity can’t ever be “created.” The Law of Conservation of Energy states that energy cannot be created or destroyed, but can only change its form. The total quantity of matter and energy available in the universe is a fixed amount. So, at a power plant, mechanical energy (the energy contained in the movement of giant magnets past coils of wire) changes to electrical energy (the flow of electrons). You can take this back even further…Where does the mechanical energy come from that moves the magnets? If the power plant runs on fossil fuels, then it comes from a form of chemical energy. Where does the chemical energy in fossil fuels come from? Fossil fuels are made from prehistoric plants, and plants get their energy from the sun. So you could say that electricity generated in a fossil fuel-burning plant ultimately comes from the sun. The mechanical energy used to move the magnets in a generating plant could also come from falling water, the ebb and flow o
