By my power-wasting standards, I use about 8 KWh a day. A max 7 MW(h?) turbine generates at most 1.94 KWh of electricity a second. It seems to take 3-4 seconds for a single turn. The math checks out and this is, as you say, incredible.
You use 8kwh==28.8MJ of energy per day. 28.8MJ/7MW turbine is about 4 seconds, as a watt is a joule per second.
In this case, there are two distinct timescales involved: the scale on which the energy is used (an hour or day) and on which it's generated (a second). It's ok to keep track of those separately.
If you want to compare, however, you will have to convert to common units, and I at least find it easier to use watts and joules than watt-hours/second and watt-hours. By all means convert to stationary-bike-hours and big macs or whatever unit at the end but calculations are easier in the SI units.
Hubble's constant is expressed like that because it is a nice unit for the math.
Three really: seconds, hours and days.
8 kWh per day = 8 Joules per second ⋅ hours per day ~= 330 Watts
Sometimes you even get four time units in one go. e.g. "I averaged 8 kWh per day last year"
It's madness.

I was like "That seems high" so I checked my usage meter and it say 112kWh. OK then. Then I notice it's set to monthly.
So that's about 4kWh per day. It will be a bunch more in winter, and your place is much bigger than mine, but still - that number seems kinda crazy huge to me.
We don't keep the house exceptionally cool. 78° during the day, 74° on the second floor at night just before bed.
I really need to try and track things down a bit better. I've got two sub-panels and it's a lot of circuits to track it down. I can start by monitoring the obvious things though: A/C units, refrigerators, dryer. I recently replaced two of the A/C units, but around the same time switch from natural gas dryer to electric and that seems to have been a wash.
Power comes from a nuclear plant less than 10 miles away, so at least it's clean? :-(
Two 14 SEER units, one 3.5 ton, one 3 ton, and a 10 SEER 2 ton unit.
1 ton = 12,000 BTU.
(6.5 x 12000) / 14 + 2 x 12000 / 10 = 7971 watts.
The air handlers have 1/5 HP motors, call that another 150 watts per air handler, so we're up to 8500 watts at least.
52 kWh / 8.5 kW is a little over 6 hours, or 1/4 of the day.
To use less power and still have a comfortable home, I'd have to insulate it better and switch to smaller and more efficient A/C units. The units are sized properly according to:

For reference, I use 30kWh/day but I live in an 80 year old all-electric house (heating, water, cooking, ...) where temperatures go down to -30 degrees celsius and winters last for 6 months. Plus both my wife and I work from home so the heating and lights etc. are on all the time. And I still think it's way too much !
Unless you are running an extremely energy intensive commercial operation at home, there's a lot of low hanging fruit to be picked. Get an energy audit yesterday. That could hugely benefit all of your comfort, your wallet and the environment.
School kids are taught (well, at least I was) small habits such as boiling just the amount of water that you need, cooking with the lid on, turning off the oven 5 minutes before the meal is done, etc.
These energy saving habits are motivated by taxes on energy consumption.
The average household in Denmark use 4.4kWh/day per person (1600kWh a year) and the current recommendation is to be aiming at 1000kWh/year[2].

A few weeks ago I was on holiday. Usage was 2.5kWh per day, about 100W, which is the fridge and a low power PC (NUC).
Otherwise, it's 3-6kWh per day, and depends whether I did laundry and cooked or not.
