When converting 68GJ to another unit of energy, it would be 18,888KWh or ~18GWh (note that h!).

EDIT: But of course, 18GWh/68GJ "per month" also gives us an average continuous power consumption of 26KW, as you have said.

No, he just dropped the per month part. 68 GJ / month, is 68 * 1 billion watts / 30 * 24 * 60 * 60 seconds, is 26 kw

EDIT: Doh! It appears I missed what blutfink was trying to say and that their changing of quantities from energy to power was intentional. Sorry for the confusion.

Whenever you have an energy use figure over a specific period, it is perfectly legitimate to calculate the average power, just as if it took you 30 min to reach your grandmother's house, which is 60 miles away, then you averaged 120 mph. In this case, an average power is an appropriate measure, as we do not know how long this page will be in service.
