A little known fact is that when heating the home incandescent lights are much more efficient. The “wasted” energy produced is diverted simply into heat, which reduces proportionately the need for other energy to heat the building. Like other forms of electrical heat light bulbs are 100% efficient.
OTOH, when cooling the home the “waste” heat of the incandescent bulbs must be removed by the AC system, making the bulbs even less energy-efficient than usually proclaimed.
So incandescent bulbs are much more efficient on an annual basis in MN than FL.
Absolutely. It wasn’t inefficient when we were living in Alaska.
Today outside of Houston, Texas, that inefficiency is at least doubled as my AC has to run to take that heat back out of the house.
Another, actually widely known, fact is that residential lighting consumes around 12% of all electrical usage.
The bulk of energy/electricity is used for space heating and cooling.
Better insulation would be more of a factor in reducing energy consumption than making it more expensive to buy light bulbs.
