Evan, I'm not against green power, I don't like the way the figures are 'glossed up' to make it seem that there is more green power being generated than there is.
I have only skimmed through a few pages of the report you mentioned.
To try to give an example, on page 14 the report mentioned that sales during the reporting period (12 months) were 1,202,079 Mega Watt Hours. That is sales from green generators over a 12 month period Australia wide.
The Energy Australia substation that feeds the lower North Shore in Sydney, has three 120 Mega Volt Amp transformers feeding that comparitively small area. This is a capability of 360 MVA at any one instant. It is only at times of light load (during the night) that the load on the substation is reduced to 200MVA. So if you multiply this coal fed capability to a 12 month period, it may put the total of 1,202,079MWh into perspective.
For the purposes of this discussion we can assume that 1 MWh =1 MVA.
