RECs allow you to easily and affordably cover your home’s electric usage with green energy. So when you buy RECs, you are certifying that your power is coming from renewable resources. Ok—but what does that actually mean?
Think about the electric grid like a tub of water being filled by many different faucets. Each faucet represents a different source of energy—wind, solar, hydroelectric, nuclear, etc. Like water entering a tub from different faucets, energy from different sources mixes together in the electric grid, and you can no longer determine the energy’s original source. So there is no way to know whether the energy that charged your phone last night came from solar, wind, or nuclear power. That’s why we have RECs—they allow us to account for the eventual usage of renewable energy in the grid. Each REC represents 1,000 kilowatt-hours (kWh) of energy produced by renewable resources, like solar and wind power. With RECs, you can rightfully claim ownership of green energy, and proudly declare that your home is powered by renewables.
