8. Phoenix Suns, US Airways Center. Staying true to their name, the Suns announced last fall that they’d be adding more than 1,100 solar panels to their facility, generating enough energy to power the equivalent of 26 home games a year. And that’s not the team’s only foray into green: when they hosted this year’s NBA All-Star Game, they asked players to create green PSAs, provided “sustainable” T-shirts for volunteers, and pushed recycling. Combine that with the city’s new sustainability plan, and the eco-cred of the Suns is surely rising.
