California continues to lead the way on clean energy, but energy efficiency and renewables are gaining major ground across the country, a new ranking of states and cities shows. Six states now get at least a fifth of their power from non-hydro renewable sources such as wind and solar—further confirmation that regardless of the Trump administration’s efforts to promote fossil-fuel interests, clean energy is making undeniable inroads.
The Golden State and Massachusetts lead the eighth annual U.S. Clean Tech Leadership Index from the research firm Clean Edge for a fifth year in a row, the latter bolstered by its strong record of energy efficiency and private investment in clean tech. Vermont, Oregon, and New York round out the top five.
The ranking scores each state on the policies, capital (both financial and human), and technology each has deployed to scale up clean energy. California, of course, has long been a leader in all three areas, with more solar energy generation than any other state, 1.2 million electric and hybrid cars on the road, and $9.5 billion in clean-tech venture capital funding over the past three years.
San Francisco, San Jose, Washington, DC, San Diego and Portland, Oregon, top the cities ranking, based on criteria including green buildings and transportation. “There are no weak spots in the City by the Bay’s performance,” the report says, highlighting San Francisco’s strong adoption of clean vehicles and an increased commitment to measuring, reporting, and reducing greenhouse gas emissions. Washington rose two spots in the ranking this year in part on the strength of its building stock and public transit ridership.
The adoption of clean energy across the United States is a trend that supersedes politics. The top 10 list for renewable electricity generation as a share of the total is split evenly between red states and blue states, with Iowa showing large gains in wind since 2009 and Nevada adding geothermal…
