The good news is that debate about the need to tackle climate change is over.
The bad news is that the debate about who pays for it is not.
In fact, as the proposed introduction of new vehicle subsidies and taxes shows, it's set to be every bit as contentious as it starts to hit us in the back pocket.
We can't avoid the politics of climate change because, sadly, when it comes to market forces the technological advances around clean energy are struggling to keep up with fossil fuels.
Late 20th century fears about peak oil proved ill-founded. Thanks
