 With New England business at 726 for the third time in six years, state senators are going all in on a sweeping clean energy bill. This time around, the proposal calls for building more electric vehicle charging stations, modernizing the electric grid and revamping the outdated permitting process. Now, the state is on a collision course with a law that calls for net zero carbon emission by the middle of the century. There's still a mountain to climb to get there. The bill heads to an overburdened house with just weeks to go in the legislative session.
