A new law , part of an ambitious energy bill , will see Washington DC run on 100 % renewable energy by 2032 , 13 years ahead of California and Hawaii . The legislation mandates the use of clean energy for utilities , rather than making it a voluntary option , and also sets a target of 10 % of electricity from solar by 2041 . Various programs will help building owners with funding retrofits, including the city’s Green Bank, which will give loans using money that initially comes from fees paid by utilities. In addition , all public vehicles , including taxis and buses , as well as private fleets of more than 50 vehicles , will be electric by 2020 , and the current energy reporting programme will be expanded to any building larger than 500 sq ft .
