Fenway Park already has its Green Monster, and now environmental activists want the whole ballpark to “go green.”

They are asking the Red Sox to commit to relying exclusively on energy from renewable sources.

The activists from Environmental Massachusetts and MASSPIRG Students announced the launch of the “Sox Go Green” campaign this week.

They’re asking the franchise to obtain 100 percent of the energy used from Fenway Park, team operations, and the team’s spring training facility in Florida from renewable resources like solar and wind power withing five years.
