Over the past six years, solar energy capacity more than doubled in 45 of America’s 57 largest cities, according to a new study released by the Environment America Research & Policy Center.

Along with the vast majority of cities that showed marked growth in solar capacity, a select group made even greater strides in going solar between 2013 and 2018, the report finds. One-third of the cities surveyed in all of the report’s editions more than quadrupled their installed solar PV capacity over that period.

“Cities are rapidly adopting solar energy and driving the renewable energy transition across the country, bringing pollution-free power to our homes, schools, and workplaces,” said Bret Fanshaw, Go Solar Campaign Director with Environment America Research & Policy Center. “We applaud the leadership shown by many cities and invite even more to let the sunshine in.”

Beyond the historical analysis, the 2018 report expanded to include 69 major U.S. cities. The newest numbers show that Honolulu rates No. 1  for solar energy installed per resident. This performance from Hawaii’s capital reflects strong state and local commitments to tackle climate change. In 2015, the Aloha State committed to using 100 percent renewable energy by 2045.

When it comes to overall solar power capacity, Los Angeles remains the leader for the second year in a row, after ceding the top spot to San Diego two years ago. L.A. has taken this spot in five of the six years of the survey.

In addition to the overall rankings, regional leaders for solar capacity per capita were Burlington, Vt. in the Northeast; Washington, D.C. in the South Atlantic; San Antonio in the South Central region; Indianapolis in the North Central region; Las Vegas in the Mountain region and Honolulu in the Pacific region.

“The difference between cities leading on solar energy and those that are lagging is effective public policy – at the state and local level,” said Abigail Bradford, report co-author and policy analyst at Frontier Group. “A dozen cities in our report have made commitments to use 100 percent renewable energy and many more have programs and policies that encourage residents to install solar panels.”
