A University of Massachusetts Amherst study of 686 large-scale solar projects has upended a prevailing narrative: most American communities embrace solar development without significant permitting conflict. The research, led by assistant professor of public policy Juniper Katz, analyzed solar facilities that went online between January 2022 and November 2023, finding that 56% of projects faced no or low conflict—a result that contradicts widespread media coverage suggesting solar opposition is commonplace.
The disconnect matters because it shapes policy decisions with consequences spanning decades. Over 25,000 local and regional governments in the US make land use decisions, and understanding the true drivers of renewable energy conflict has become increasingly important as states and cities race to expand clean energy capacity. When public perception diverges sharply from evidence, it can distort how communities approach permitting and siting processes, potentially slowing the energy transition unnecessarily.
The research reveals an unexpected hierarchy of influence. Contrary to studies on wind projects, the political composition of communities proved irrelevant: the share of Democratic voters in areas surrounding solar sites showed no statistically significant relationship to opposition levels. Neither did wealth nor racial demographics predict conflict, bucking assumptions about which neighborhoods resist clean energy. Instead, institutional arrangements—specifically how permitting authority is structured—emerged as a primary factor. Projects approved under state-level permitting systems showed substantially lower conflict compared to those reviewed through local or hybrid structures, where divergent interests can collide more visibly.
Scale also matters. Larger utility-scale solar installations, by their nature feeding substantial electricity to the grid, encountered more permitting friction than smaller projects. Yet even among these significant undertakings, 56% proceeded with minimal opposition. Only 19% of the 686 projects analyzed experienced high levels of conflict, defined through measurement of news coverage and social media posts using terms like "protest," "lawsuit," and "opposition."
This finding arrives at a crucial moment for American energy strategy. Renewable energy sources grew more than 11% in the first quarter of 2024 compared to the previous year, with utility-scale solar leading the surge at 23.9% growth. Wind and solar together account for less than 5% of electricity bill increases over the past decade—a fact that increasingly shapes public attitudes. As renewable energy continues driving down wholesale energy prices, more Americans recognize that clean energy expansion strengthens rather than strains the grid's affordability.
The Katz team's work suggests that when citizens and governments acknowledge permitting processes can be adversarial, they become more likely to seek constructive approaches. That recognition could unlock faster solar deployment across the political spectrum. Meaningful clean energy progress has already taken place in red, blue, and purple states alike, often through quiet collaboration rather than contentious battles.
The implications are profound: if most communities welcome solar projects when processes are transparent and state-level systems are in place, then permitting reform—not public opposition—may be the real lever for accelerating America's energy transition. The story the data tells is far simpler and more hopeful than the conflicts that dominate headlines.
