When I was an undergrad at WPI I worked on a project with a startup that was working to encourage the adoption of renewable energy sources. I was disappointed to learn that the system is being nixed. The cost of energy in Connecticut is high and will likely only increase. With incentives I would expect installing a Geothermal system to be a net win for the town.
On a related note I also find it disappointing that the state has stalled in lifting its ban on wind turbines. As a state that is trying to lead on energy issues I would expect us to be doing more to encourage this.
