That is NOT true. Motors and heaters use the most electricity. A fan/blower is a motor with blades on the end, or a squirrel cage on the end.
Just ask any restaurant owner. He has cold storage rooms that have refrigeration compressors, a multiple exhaust fans over the grills, exhaust fans to move heat out of the kitchen, and large heating/cooling units on the roof to keep the dining area happy. Ask him about his electric bill.

Sure, but furnace blowers don't use that much electricity so they're not the reason the grid is overloaded.
Yes fans use energy, but compared to the usage for those refrigeration compressors, resistance heaters for heat pumps, and so on, they are a small fraction of the total usage. You need the fans to move the heated or cooled air, but it does not take nearly as much energy as the actual heating and cooling.
