The "90% renewables" solution
Vermont has an energy policy that requires that 90% of Vermont's energy come from renewables by 2050. This policy includes all of Vermont's energy, including heating and transportation. Such a change can most generously be described as "unlikely." I have at least two blog posts on this subject: What 90% renewables would look like in Vermont, and Vermont's renewable plan is wishful thinking These posts are from 2013.
The renewable policy might become a law
So far, this renewable policy is not law, but it might become law. The legislature is in session, and, as Mark Twain said: "No man's life, liberty or property are safe while the legislature is in session." Bills are being introduced to make this policy into an actual law.
The Ethan Allen Institute recently made a video on the folly of 90% renewables for Vermont. I appear briefly in the video. I hope you enjoy it.
