But fusion won't be available in 10 years either. There is a long, long way from net energy positive to mass rollout. Fusion is going to be harder than fission, and fission took 30 years from first controlled fission to 1% of electricity supply, which is the lowest which i could call 'mass rollout'. In 10 years though, renewables will be definitely making it - becoming cheaper than any new type of generation , probably almost stopping construction of any new non-relewable generation. Peak use of fossil fuels for electricity generation is now projected to happen in 2025. Trillions of dollars are being invested in infrastructure now - and yes, it is mostly investment into renewables already.
