The index is a rules based index intended to track the overall performance of renewable energy companies which may include, but is not limited to: wind, solar, hydro, hydrogen, bio-fuel or geothermal technology, lithium-ion batteries, electric vehicles and related equipment, waste-to-energy production, smart grid technologies, or building or industrial materials that reduce carbon emissions or energy consumption.
