Now that President Joe Biden has assumed office, he can get to work on his pledge to move the nation to 100 percent clean energy.
During the campaign, Biden advocated a 100 percent clean energy standard pegged to 2035. This builds on state-level renewable portfolio standards, which spurred tremendous growth in renewables by mandating that utilities buy or produce a certain amount of clean power by certain deadlines. Biden wants to apply the concept nationally while front-loading investment in clean energy and technology to bring down costs.
