Railroads have become a nexus of controversy in recent years due to their role in transporting climate-twisting fossil fuels. But they could become a locomotive driving the growth of clean energy. That is the aim of a new proposal to electrify railroads, run them on renewable energy, and use rail corridors as electricity superhighways to carry power from remote solar and wind installations to population centers.

The proposal, called Solutionary Rail, has been developed by a team of rail experts, economists, and public interest advocates assembled by the Washington state–based Backbone Campaign. Bill McKibben writes in the foreword to the recently released Solutionary Rail book that he has “been following the debate over energy, transportation, and climate change since the late 1980s … So it’s hard to come up with an idea I haven’t come across before. Rail electrification, as proposed in this remarkable book, is that rarest of things: a genuinely new idea, and one that makes immediate gut sense.”

An activist movement, sometimes known as the “thin green line,” has grown up in the Northwest in recent years to resist coal and oil shipments through the region, between the rich fossil resources east of the Rockies and the growing markets of Asia. The Backbone Campaign, a group that develops innovative strategies and tactics to build grassroots democratic movements, has been enmeshed in this movement.
