No. It's the average electric-power generation. The installed capacity would be the average generation multiplied by the capacity factor.

> an installed capacity of 2 Terawatts will over the course of a year if run 24 hours a day will produce 2 x 24 x 365 Terawatt hours = 17,520 Terawatthours.

Yes.

I just used the numbers given in the previous emails.
However let's get the actual figures:

From http://www.eia.doe.gov/emeu/international/electricitycapacity.html
Table 6.4 Electricity Installed Capacity, All Countries, January 1,
1980 - January 1, 2006, Except as Noted, for the International Energy
Annual 2006*/
/*The installed capacity as of 2006 was 4 Terawatts*/

From http://www.eia.doe.gov/emeu/international/electricitygeneration.html
Table 6.3 World Total Net Electricity Generation, 1980-2006
The electricity generated as of 2006 was 18,014 Terawatt hours

From http://www.eia.doe.gov/emeu/international/electricityconsumption.html
Table 6.2 World Total Net Electricity Consumption, 1980-2006
The electricity consumed as of 2006 was 16,378 Terawatt hours
