Washington, D.C., aims to source all its power from renewable sources by 2030, and energy suppliers who do not meet this goal will be heavily fined. This threat has spurred energy suppliers to purchase Solar Energy Renewable Credits from people who have installed solar systems. Institutions like Gonzaga College High School have benefited from this situation by renting out their ample roof space to investors. Gonzaga's solar system has been installed by an investment company that pays the school $20,000 a year as rent for its roofs. All the power generated goes to the school, saving $75,000 a year on energy bills, and the energy company purchases any surplus power. The investment company makes money by selling the SERCs to the energy company. This is indeed a situation where everybody wins.
