Let's move on with steps towards this ideal -- in fact, in 2013, I'd settle for saving petroleum products for aircraft and shifting ground transportation off of fossil fuels (bicycles, plug-in cars)

Good idea, Anne.

Here's hoping.

I'm sure this has been known all along.The "powers-that-be" will never allow this to happen quickly. It will be like that film "Chain Reaction". Economies will collapse if the fossil fuel market suddenly becomes obsolete.

As Nimue said it would be hard to achieve this in two decades but I would be more than happy if it happens in 3 or four. That would be fantastic success.

At the present rate of emissions, even if greenhouse gas emissions don't increase, we don't have three or four decades to avoid passing irreversible tipping points. We are headed for a climate nightmare.A radical transition as quickly as possible is the only thing that will save us.

Interesting article. Debates continue to rage about if it's realistic to shift this far at this speed (probably not quite this fast) but it is illustrative of the kind of shift we need to be making. Add in a radical energy efficiency programme to reduce the overall energy demand significantly and add some of the right sorts of biomass / biofuel options (i.e. 2nd generation ones that don't pull away the supply of important food crops) and a few other options not used in this calculation and it starts to be more possible. It will probably need some fossil fuels to support this mix for a good while yet but the sooner the signifcant switching and the demand reduction gets going the better!

The "all of the above" strategy favored by many in our corporate government is tantamount to drilling holes in the Titanic to let in more water. We are so close to an irreversible, catastrophic collision with climate change that nothing less than a radical transition is likely to have any hope at all of saving us. We must ditch fossil fuels as quickly as possible, and switch to clean, renewable energy.
