As a group, states are already doing more to support clean energy development than the federal government ever dreamed of.
Standards. State governments have the power to mandate certain outcomes. In clean energy, the two most important requirements for states to enforce are building codes and renewable-portfolio standards. Building codes can require certain levels of energy efficiency in new construction, for instance, which can lock in energy savings over the decades-long lifespan of a building. Renewable portfolio standards require utilities to source a fixed percentage of their power from renewable sources by set deadlines.
Connections. Renewable energy installations aren’t much use unless they connect back to the grid, so states need rules for distributed energy sources like rooftop solar to connect back to the grid. Regulations like these also make it possible for the owners of distributed-energy sources to sell power back to the grid or receive credit on their energy bills for the power they contributed.
Money. In the end, though, growing clean energy means building more renewable power projects, which requires financing. States have such a range of programs in place—including grants, rebates, loans, and loan guarantees—that researchers looking at state-level policies have had a difficult time deducing which ones are working best. The Brookings Institution released a report this month advocating creation of state clean energy funds to support individual projects. Brookings sees these funds as a potential engine of innovation, too, funding clean-energy startups and cutting-edge research and development.
While the federal government backs off from its support of clean energy, state policies like these are increasingly essential for the industry’s continued growth. State-level regulations have a trickle-down effect, too: It’s easier for local governments to push for clean energy in states with strong frameworks. Of course, that would be true for federal level policies, too—while it's heartening that states are taking initiative, they would be able to achieve more with some increased leadership from Washington.
