Why Massachusetts is the best state for landfill solar arrays

A 2.2-megawatt solar array on a shuttered municipal solid waste landfill in Lexington, Massachusetts, is not particularly remarkable on its own. But this, combined with 100 or so other similar brownfield projects in Massachusetts, make the state a national leader in converting formerly contaminated sites to clean energy production. Though a few sites feature wind turbines, photovoltaic panels dominate. And advocates credit the state’s clean energy policies as well as the abundance of suitable sites. Massachusetts accounts for roughly 40 percent of the 253 renewable energy installations identified thus far by the U.S. Environmental Protection Agency’s RE-Powering America’s Land Initiative — or at least 258 of the 1,398 total megawatts brought online through October.
