Winter energy could be done on a (smaller) community basis ... if it constructs a large enough, well-insulated thermal mass, or is lucky to live by one. I grew up in a place where, each winter, a large lake was covered-over by a couple of feet of ice. (Often covered by snow.) The water beneath stayed liquid. A heat-pump under the ice could draw on that source.

Worldwide, the ground itself, a few feet down, stays at about 50F year-around ~~ regardless of outdoor temperature. Locally, summer heat-pumping could be directed underground in some places. Reverse in winter.

Pumping heat from where it's stored is a lot less expensive than transporting and burning fuels. We do need to get better at it.
