Last week, the state of Hawaii approved its first roll-out of Feed-in Tariffs (FIT), a reward program that allows homes and businesses to get paid for building renewable energy systems such as rooftop solar panels and feeding that energy into the electric grid. To implement the plan, companies that install and maintain a renewable source device receive a Power Purchase Agreement from a utility, while the state government regulates the electricity tariff rate. The Hawaii FIT program roll-out will take place on all of the state's grids within six weeks. Hawaii joins Vermont, Washington, California, and Oregon in introducing statewide feed-in-tariffs.
