How do I know I’m using clean energy?

The only way to use clean energy without producing it yourself is by buying Renewable Energy Certificates (RECs) to match your usage. RECs were created to allow tracking of renewable electricity – which is physically impossible – from the source (e.g. wind turbine, solar farm) to the end user (you). A REC is a claim on the social, environmental, and other non-power related attributes of electricity produced by renewable sources.
