I guess that answers the question about Rudd and renewables. Since there are nearly 9000 hours in a year that 2020 target approaches 5 Gw continuous average, maybe 10% of all current installed capacity. I surmise that since CSP, geothermal and solar towers can't be sure of their contribution to the 20% target (circa 10 Gw) that investment remains more of a gamble than windpower.

While we're still smitten with Rudd remember so far it's all talk and that the renewables surge is yet to happen. At least Howard had a cycle commuting minister in Tony Abbott. I note on telly tonight that Premier Lennon reneged on his promise to get a hybrid and is now cruising the boulevards in a shiny new Statesman. I have this horrible feeling we are going to be disappointed in the new 'green' ALP.
