Green Energy for Federal Buildings Act

This bill sets new renewable energy targets for federal buildings, requiring the U.S. government to increase its use of renewable energy over time. It mandates that federal agencies meet minimum renewable energy consumption levels: 7.5% from 2013-2019, rising to 35% by 2030-2039, 75% by 2040-2049, and 100% starting in 2050. The law directs agencies to prioritize on-site, on federal lands, or on tribal lands renewable energy projects where economically and technically feasible. These requirements directly affect all federal buildings and agencies managing energy procurement.
