I'm not convinced technology is going to help us. We have had amazing efficiency gains for aircraft but increased air travel has eaten all the gains and a lot more. We have built more efficient cars but wasted that by building bigger cars and driving them further. Insulation standards in homes have increased but we build bigger homes further from the centres. The list goes on and on.

The only thing that has made a real difference is switching from coal to gas in places like the UK. But even then gas heating in our homes is emitting more CO2 than any other sector.

Wind and solar are too intermittent to replace base load, there isn't enough cobalt in the world to build enough storage, there probably isn't enough uranium to switch everyone to nuclear.

I can't see people accepting a shift from an energy system based on stocks to one based on flow and the intermittency that comes with that. My neighbours go a bit bananas when the power is off for thirty minutes.

We really are fucked.
