The issue isn't that we as a race can reach 100% renewable energy, it's at what cost? Right now displacing fossil fuels comes at such an enormous financial cost it's an all of humanity thing or none (or very little) of humanity thing. Also there would be such high costs for poor nations that rich nations would have to pay way more than their proportional share. Sadly it's wishful thinking to get the entire human population/their respective representatives and despots to agree to solve this problem. Our best hope is that a new technological solution with near zero marginal cost emerges and displaces fossil fuels as much as possible.
