In the U.S., taking the train is already one of the climate-friendliest ways of getting around.

New Jersey’s Democratic Governor, Phil Murphy, set the East Coast’s most ambitious target for offshore wind energy last week, vowing in an executive order to develop 11 gigawatts by 2040 — enough to power about 4.7 million homes. The announcement now puts New Jersey ahead of other renewable energy powerhouses in the Northeast.
