For several years now, a company called BNE Energy has wanted to place electricity-generating turbines in the Litchfield County town of Colebrook. The proposal has sparked vigorous legal opposition from nearby property owners and has prompted a long-running debate over proposed regulations governing wind energy projects in the state.

Now BNE is in the middle of another dispute. In 2010, in Canaan, about 20 miles west of the proposed Colebrook wind farm, the energy firm paid to have a wide swath of tall hemlocks, oaks and other trees cut down. The stated goal was to facilitate a study to see if that site would be appropriate for turbines.
