Massachusetts is in the midst of procuring vast amounts of clean energy, but on Beacon Hill clean energy advocates say the state isn’t doing nearly enough.

The Senate approved legislation that would triple the annual increase in renewable energy purchases. The House last week took up a bill that would have doubled the annual increase, but then, under pressure from some in the business community, watered it down when the legislation came up for a final vote. The House and Senate will now have to decide whether they can come to agreement on a final bill.

It’s become one of the hottest issues on Beacon Hill, but few understand it well. Three chamber of commerce CEOs, in an op-ed in CommonWealth, insisted Massachusetts was falling behind its neighboring states in pursuing renewables. The CEOs even suggested the state’s bid to build an offshore wind power industry was in jeopardy if much higher renewable purchases were not mandated. “We cannot afford to lose this competition to other states,” they said.

Today’s Codcast takes a closer look at the complex issue and the big takeaway is that the debate over renewables is really a debate about which renewables we should promote.
