Homeowners across the country are plugging into solar energy to reduce electric bills and actually earn credits for electricity that is fed back to the utility company. Today, more than 40 states allow property owners to sell excess energy generated by solar panels onto the electric grid, and many utilities must pay a premium for this resource. Analysts predict that in just five years solar installations will account for roughly 1.5 percent of global energy demand. REA offers programs to help homeowners take advantage of this affordable solar energy revolution.
