Renewable Energy Resource

Use of non-fossil fuels to generate electricity (e.g., wind, solar, biomass); these are sometimes referred to as green options. They are often limited in the amount (and reliability) of energy obtained in a given time period. Utility applications for renewable resources include bulk electricity generation, on-site electricity generation, distributed electricity generation, and non-grid-connected generation. Demand-reduction through energy efficient technologies is a substitute for energy-whatever the source.
