"Do your part" energy conservation plans, like turning lights off when you leave the room, are great for your energy bill, but their job as part of "lowering carbon footprints" is to deflect from the big corporations that actually use the vast majority of the power.

For example, the average US stand-alone home uses ~11,000 kWh per year.

The VERY MOST EFFICIENT roadside LED billboard uses ~61,000 kWh per year. That number rises to ~323,000 kWh at the top end.
