Representatives from 30 European cities got together in Paris last week to formally commit themselves to reducing greenhouse gas emissions no less than 40% by 2030 — the same target set by the European Union’s climate change roadmap — and to call attention to the role major urban centers can play in combating global warming.
According to a joint statement published in French newspaper Le Monde, the representatives say that while climate change is a global issue, the solutions are primarily local, which was why they “decided to join forces and strengthen the instruments that will lead us toward the energy and environmental transition.”
While there haven’t been any major gatherings by mayors of cities in the United States recently, there are still plenty of local solutions being implemented. And, as you might expect, some major American cities are better poised to reap the benefits of the clean energy revolution than others.
For instance, Los Angeles currently has more solar photovoltaic capacity installed than any other American city, followed by San Diego, Phoenix, Indianapolis and San Jose, California.
If you sort major American cities by installed solar PV per capita, however, then Honolulu, Indianapolis, San Jose, San Diego and Wilmington, Delaware top the list. All of them have 50 watts or more of installed capacity per resident, qualifying them as what a new report by Environment America calls America’s “Solar Stars.”
