Terms & Definitions
Green tags (also known as green energy certificates, tradable renewable certificates, and renewable energy certificates (REC), are the "green attributes" of renewable energy production. The "green attributes" are separate from the physical electrons, which power our lights, computers and other electronic equipment, and are those features that make renewable energy attractive compared to more traditional energy sources - reduced impact on air and water quality, non-finite resource, the replacement of energy from traditional fuels. Most REC's or Green Tags are sold for the equivalent of 1,000 kwh (or 1 MWh) of electricity. Many green tags are "certified", meaning that an organization ensures that the REC's you buy are backed up by equivalent renewable electricity generation. Read here for more on Green Tags.
