Massachusetts recently enacted a bill called the Green Communities Act to promote renewable energy with mandates an incentives. Massachusetts already had a Renewable Portfolio Standard, but this legislation doubles the adoption rate required, increases net metering for wind and solar from 60 kilowatts to 2 megawatts, and requires utilities to sign 10 to 15-year contracts for renewable energy. Masschusetts plans to have 4% renewables by 2009, increasing by 1% each year (e.g. 15% in 2020), with no cap. It allows utilities to put solar on their customers’ roofs.
The legislation also promotes efficiency with rebates for lighting and air conditioning, and mandates all utilitiy efficiency improvements that cost less than it does to generate power.
