Around 400,000 Kw per month?  That's based upon just the CPU, not
counting the disk drives and cooling system.  People looked at my
really strangly when I asked.

I wonder if they looked at you strangely because you were asking about
MW per day or kW per month? :-)

As far as I know, Watts are a measure of power, which is how much energy
moves around per unit time.  The machine doesn't use 400,000 kW per month.
It uses 400,000 kW, which by definition is 400,000 kJ per second, or about
1 million MJ per month.  J is Joules, a measure of energy.

The only way that "kW per month" might make sense is if the power consumption
changes regularly, e.g. if you buy a new disc drive every month.

Or have the laws of physics changed while I've been sleeping? :-)
