Despite my cynicism to follow, this is actually a pretty significant announcement. Certainly a big change in Liberal Party politics.

Now when the Rudd Government finally announces some token level of support for solar power, the Liberals can say it was their idea (but at least the opposition is not going to block support for solar power). Instead, they'll argue against whatever form of carbon trading Rudd chooses and just refer to their 'solar plan' as the best way forward.

I guess we have to be thankful for small steps forward? Adding a significant cost of carbon to the economy at a time when consumers are starting to feel pain on several fronts is going to give the opposition plenty of things to bleat about.

The Libs must be fond of wind power, too - since being demolished at the election they've started flipping around like a turbine.

It could just be a bit of wedge politics of course - they can always hope that Labor does the sensible thing and adopts this policy, then turn around and call them economy wrecking greenies...
