I can literally look up my hourly power usage online. The 4-6 hours my pool pump is on is almost 2x higher power usage than any other time. I consider that a lot of power.
Edit: we had our house unoccupied for 2 months with everything unplugged and off, but our pool pump and sprinkler system. Based upon that, and looking at our historical usage, I would say our pool pump accounts for about 65% of our monthly kwh.
Wow, it surprises me that it's that high, but you clearly know your numbers. Presumably the rest of your house is quite energy efficient?
If it something that interests you, you could probably reduce the power usage considerably by switching to a smaller pump that runs for more hours. All else equal, the power required for pumps increases much more than linearly (proportional to the cube of the flow), so a pump with half the flow rate that is run for twice as long would use less than half the total energy per day for the same amount of water circulation.
