You are confusing MW with MWh and apparently kWh.

A single rack in a corporate server room consumes on the order of 10 to 20kW.

1MWh happens when you run a 1MW load for 1 hour. There are 1000 kWh in 1MWh and 1000 Wh in 1 kWh.

A home with 1344W of constant consumption would consume 32kWh per day.
