I lived in Stamford, CT then. Great winter for sure. Christmas trees buried in snow for months.
How much energy did that save? None.
Certain brilliant members in Congress might claim more sun is result of climate change and that we only have 12 more years to save the planet. Those 12-year or 10-year claims remind me of the 10- 14- day modeling of winter's arrival this year. Yawn.
The only area it would remotely (no pun intended) benefit is eastern Maine. That was considered when I lived up there in 2005 or so. Fell flat pretty quickly.
