The solution is reduce energy demand and live within a sustainable energy budget.
Fuck that.
Increasing energy demand is so closely linked to civilisation that one can measure the latter solely by reference to the former. A Tanzanian subsistence farmer lives within a sustainable energy budget. No urban American ever could - without energy, a modern city is ininhabitable.
Energy poverty is no more desirable than financial poverty - it is strictly for monks and other religious kooks.
And if energy poverty were imposed on the Earth today, it would entail the deaths of billions.
The solution is nuclear fission. We can have as much energy as we want, whenever we want it, at roughly the same dollar cost we currently pay, and with zero carbon dioxide emissions, with safety and health levels that are as good as we have ever been able to achieve, and whose waste products are so small in volume that we have seventy years worth of them in storage where it has never hurt anyone, and has done about the same environmental damage as laying a concrete driveway. Oh, and the "waste" can be used as fuel in more modern reactor designs.
A profligate American electricity user, if his energy were supplied from fast spectrum fission reactors, would produce in his entire lifetime a volume of waste the size of three m&m's. If we use the highly inefficient thermal spectrum reactors that are the current technology, that waste volume "balloons" to the volume of a can of Coke.
All the problems with nuclear power that were panicked over in the 1960s and '70s have turned out to be nonexistent - pure fear, no reality. The only remaining cards that the anti-nuclear lobby have to play are "It's unpopular" and "It's expensive", and both are entirly due to their concerted effort to make it so.
There is no technical reason why nuclear fission should be either. If it were invented today for the first time, a new technology that generates carbon-free electricity, 24x7, with minuscule use of materials and minuscle waste products, we would be calling it the miracle solution to climate change.
Lots of people are hanging out for fusion power, as that "miracle solution" - but literally the ONLY thing fusion power has going for it, that fission doesn't, is that fusion power doesn't exist, so we can imagine any problems it may create not to exist either.
