I hate to be a spoil-sport, but that article didn't say 1 word about how much energy went in to produce that turkey, and no wild/free-range/heritage turkey is likely to dress out at 30 lbs! Canadian Thanksgiving was a month ago and I served a Muscovy duck raised on my
land with only some commercial
feed and lots and lots of grass. My friend was ticked that I didn't have a goose to offer up, but our geese seem to have lost their fertility - next year's problem!
That said, I will also note that for anyone heating with electricity, the power to cook is displacing at least some of the power to heat the house. If you invite guests, they add their own BTU's, and that lowers the demand for heating further. So long as they turned their own heat down when the left their own house, that's a win also!
