The future of clean energy depends on meetings like the one held at a small hotel in a small city in Massachusetts last month. Residents of New Bedford came together to voice their opinions about an offshore wind proposal from a company called Vineyard Wind. To date, such projects have not fared well in America; opponents have blocked big offshore wind farms. But opposition has dwindled. Though lobstermen fretted about local crustacea, supporters of the project in New Bedford touted the new jobs that would be on offer. Bureaucrats overseeing the plan offered heart-shaped chocolates at the sign-in table. If Vineyard Wind secures the necessary approvals, the project would be, astonishingly, America's first large offshore wind farm. Construction could begin by the end of the year.
