When energy is made from a renewable energy source, the government can offer renewable energy certificates, or RECs, to the energy producer. Also known as renewable energy credits or greentags, renewable energy certificates provide key information about the type of energy put into the electrical grid. According to the Environmental Protection Agency, RECs usually include information about:
- The renewable resource that produced the REC
- The date the REC was created
- The date the REC generator was built
- The location of the REC generator
- The REC generator’s greenhouse gas emissions
Renewable energy certificates can be viewed as the “currency” of the renewable energy markets. They are traded back and forth between companies in order to show that the companies have made renewable energy a priority.
