Just remember that anything that heats or provides heat is costly to use; curtail excess usage as much as possible;

That includes adjusting household temps when occupants are out of the home. - Turn down (sometimes turn off) heat a few degrees or more when leaving; when you return turn up heat gradually - a degree or two at a time until you're at or near desired setting.
Reverse for AC - turn up temps a few (or more) degrees when leaving, then adjust a degree or two at a time until at desired temp.

Keep throws - (small blankets)- available near where you watch TV or otherwise lounge in place.

Yes, turn out lights when leaving a room, but always provide enough light when moving throughout the house, to avoid falls, especially if older.
