No matter how much we talk about it, there is only one known solution, nuclear power. The world cannot afford to go 100% nuclear before 2050 IF it were politically possible.
Every other non-fossil energy source not only requires breakthroughs which may never happen or never at an affordable price has a chance by present knowledge. But if all the breakthroughs were to happen tomorrow we are still decades away from a total replacement.
There are two costs, acquisition and ownership. The former is the enter energy producing system hardware. The latter is the cost of fuel and maintenance. If everything were to go swimmingly the only savings would be the fuel.
I have this persistent image of this same discussion a century from now after the world has adapted to higher temperatures on what to burn to keep it warmer.
