There was a mistake which I fixed in the next email - it should have
been about 754W, not 300W.

That aside, both figures are Watts, not Watt Hours.  A Watt is a measure
or power, not energy.  The units are Joules per second.  So I am saying
when averaged over the year, a household consumes 754 Watts every
second.

Indeed.  A MWh is a measure of energy, not power.  Since my 754 Watts is
the amount of energy a house would consume in once second, you have to
multiply it by the number of hours per year to get Watt hours consumed
in a year.

When you do that you get:

    754 [Watts] * 24 [Hours/Day] * 366 [Days/Year]
  = 6.6 MWHr/year.

OK, that isn't 18MHr/year.  But 6.6MWHr is what the average Victorian
household uses, so your consumption far bigger than normal.  Maybe you
have lots of kids, or maybe a teenage daughter?
