Think nuclear fission reactors will help? No.
We have to build 1031 nuclear reactors per year for 45 years
* 439 nuclear reactors exist on Earth which generate 2796 TWh. So that is an average 6.3690205011 TWh per nuclear reactor
* Oil + Coal + Gas + Firewood generate 147872 TWh
* So we need 147872 / 6.3690205011 = 23217 nuclear reactors.
* And in the next 45 years the world will consume twice the energy it consumes today.
* So in 45 years the world needs: 46434 nuclear reactors
* That means the world has to build:1031 nuclear reactors per year.
* Currently the world is building:55 nuclear reactors
* It takes 10 years to build an average nuclear reactor like the 439 that exist today.
* That means we have to start 10,000 new nuclear reactor projects today to meet the target.
