With well-known sources like hydro, wind and solar at the forefront, many countries have made impressive strides transitioning to clean energy. Still, the challenges are immense: Consider that only 13 percent of the electricity produced in the United States comes from renewable sources. As the essential push toward a low-carbon future accelerates, though, how do we balance the benefits with the potential risks to nature? What are the tools—technology, policy, markets and beyond—that will help us produce the clean energy we need in New England and globally, while protecting the health of our rivers and minimizing energy sprawl and other impacts? What role can lesser known renewable sources like biomass and tidal power play?
