Honolulu is America’s greenest city, according to a list released by NerdWallet, a San Francisco-based financial website. Hono­lulu’s air quality and use of solar energy earned the city the No. 1 spot out of the 150 cities NerdWallet considered.

"This city in the nation’s 50th state tops our list with its air quality, the best of all the cities we analyzed, and for residents’ widespread use of solar energy. In 2014, the city received the EPA’s highest classification of ‘good’ for 351 of the 360 days measured, giving it a median Air Quality Index of 27 for the year."

With more than 100 buildings with solar per every 10,000, Hono­lulu had over five times more than runner-up Oakland, Calif., with 22 buildings.
