Thousands of clean energy projects are waiting to connect to the grid. How many will make it through, and will it be soon enough to keep the grid reliable?

---

Electricity demand in the U.S. is rising fast, fueled by the rapid growth of AI data centers and other power-hungry technologies. At the same time, many fossil fuel power plants are retiring, putting added pressure on the grid to maintain reliability.

To meet this challenge, clean energy and battery storage projects are lining up to connect to the grid. The queue now holds more than twice the capacity of all power plants currently in operation.

But getting these projects online is proving difficult. The interconnection process, which evaluates and connects new power projects to the grid, has become a major bottleneck. It is overwhelmed by the sheer number of proposed projects and further slowed by permitting challenges, supply chain delays, and uncertainty around federal incentives. Reforms to the interconnection process are underway, but it is yet to be seen whether they will move quickly enough to make a difference.

RMI’s Sarah Toth Kotwis explores the technical and regulatory barriers to bringing new energy online, and what it will take connect new energy projects quickly and reliably.

BloombergNEF’s Derrick Flakoll discusses the outlook for U.S. clean energy development under the House version of Trump’s “Big Beautiful Bill.”

---

On May 22, the House of Representatives passed its version of what President Trump has dubbed the “Big Beautiful Bill,” a sweeping budget package addressing taxation, federal spending, and the debt ceiling. Now headed to the Senate, a revised version is expected to emerge by early July.

The House bill proposes deep funding cuts to programs like Medicaid and extends the Trump-era tax cuts from 2017. For the clean energy sector, however, the most consequential provisions are those targeting the Inflation Reduction Act. As written, the legislation would significantly curtail tax credits for renewable energy projects and the domestic manufacturing base that supports them. Incentives for electric vehicles and EV charging infrastructure, as well as battery storage, hydrogen, and nuclear power would also be sharply reduced or eliminated altogether.

Derrick Flakoll, U.S. Policy Expert at BloombergNEF, examines what this could mean for the future of clean energy in the United States. BloombergNEF recently released an analysis projecting the impacts of the House bill on clean energy growth and investment. Flakoll outlines the report’s findings, including the resilience of clean energy markets without IRA tax credits, which sectors face the greatest risks, and how the proposed “Foreign Entity of Concern” provisions could further complicate project development.

He also considers how the Senate might alter the legislation and whether any of the IRA’s clean energy incentives are likely to remain intact.

As renewable power grows, land use decisions will influence its environmental impact.

---

Decarbonizing the electric grid will require a dramatic expansion of renewable energy by mid-century, and significantly more land dedicated to clean power. But where and how that buildout occurs will shape whether the environmental benefits of renewables are fully realized or come at a high cost to ecosystems, farmland, and communities.

Grace Wu of the Spatial Climate Solutions Lab at UC Santa Barbara and Jonathan Thompson, research director at Harvard Forest, examine the tension between rapid renewable energy expansion and conscientious land use. Wu, who has co-authored recent reports on the environmental impacts of clean energy siting policies, explores strategies for minimizing impacts while ensuring energy remains reliable and affordable. Thompson, whose research quantifies the effects of land use on forest ecosystems, discusses the push-and-pull dynamic unfolding in Massachusetts, where solar development has resulted in real losses of forests and farmland, and where new siting models are emerging.

The two also explore how incentives and regulations influence land use decisions, and how policy can reduce land impacts while supporting clean power development.

Grace Wu is an assistant professor in the Environmental Studies program at the University of California Santa Barbara and leads the university’s Spatial Climate Solutions Lab.

Jonathan Thompson is senior ecologist and research director at Harvard Forest.
