States’ renewable energy mandates vary considerably, typically ranging from 10 to 50 percent of a state’s electricity production. Renewable portfolio standards are credited with spurring half the growth in renewable energy production since 2000. Factors besides state mandates that have driven renewable energy growth include federal tax credits, cost declines and corporate renewable energy goals. The utility also sued to keep the renewable energy measure off the ballot, arguing it lacked enough signatures, but lost that case in court. Specifically, in 2016, between 70 and 90 percent of renewable energy additions in the Northeast, Mid-Atlantic and West served demand created by renewable energy portfolio policies, the report said.
