The nation’s environmental laws, especially the National Environmental Policy Act, arose from a sensible desire to ensure that big projects didn’t cause big environmental problems. But members of both parties agree that over time the requirements imposed by the law, which requires careful examination of the impact of major projects, have become unnecessarily cumbersome. One recent analysis calculated that it takes the government a median period of 3.5 years to review renewable energy projects.

The competing environmental priorities of developing renewable energy and protecting existing ecosystems can be better balanced by imposing strict time limits on environmental reviews while also increasing funding to ensure regulators have the capacity to meet those deadlines. Congress also could expedite consideration of inevitable legal challenges by adopting a proposal recently highlighted by the Brookings Institution to send challenges to the Court of Appeals for the D.C. Circuit.

Instead of waiting for companies to propose projects, the Energy Department also can accelerate construction — and focus private investment — by identifying where power lines should go and beginning the approval process before companies apply. The Inflation Reduction Act strengthened the federal government’s authority to engage in this kind of planning, but states have resisted federal encroachment on their authority and the Biden administration has declined to force the issue, emphasizing its desire to work with states.

In January, the administration celebrated a small victory, sending Vice President Kamala Harris to Arizona for the groundbreaking on the Ten West Link power line project between Arizona and California, which was first proposed in 2015. But far too many projects remain in limbo, in part because states and communities along power line routes have little incentive to quickly approve projects intended to deliver electricity somewhere else.

The nation’s transmission lines also are broken up into regional grids that operate like jealous petty potentates, resisting stronger links that would allow renewable energy to flow across regional boundaries. In the Midwest, where the Energy Department says the need for new power lines is greatest, the list of projects in limbo includes the SOO Green Line, proposed in 2012, which would carry electricity from Iowa to the outskirts of Chicago underground, alongside railroad tracks. The line would connect a grid called MISO, which covers part of the Plains region, with a grid called PJM, which serves parts of the Midwest and the Mid-Atlantic and has opposed the project.

This Balkanization of the electric grid keeps costs unnecessarily high and makes it harder for utilities to meet surges in demand. In February 2021, more than 100 people froze to death in Texas, in part because the local grid operator, the Electric Reliability Organization of Texas, had limited capacity to draw power from neighboring grids. Congress can encourage a greater spirit of cooperation and help to combat climate change by mandating a minimum transfer capacity for each grid.

Congress and the Biden administration have taken a series of promising steps toward ending the nation’s dependence on carbon. But the absence of a plan to build a new electric grid is a critical hole in that emerging strategy. Without decisive action, they will waste a precious chance to limit climate change.
