The largest city in the state of Vermont in America has grabbed headlines this week for being the first city in the U.S. to be powered 100% by renewables.
Burlington has a population of 42,000 and has facilitated this energy generation change without raising rates since 2009. Reliant on coal a generation ago, the largest share of electricity in the city comes from hydropower, much of which has been purchased from plants running in Maine.
Approximately 20% of the city’s electricity comes from wind power, and a smaller percentage from solar energy.
A smart grid project has also helped the city use energy more efficiently. The city actually uses less energy today than it did in 1989.
