The things that will work, but can't be done: Walk/bike instead of vehicles, no crypto and AI (tremendous hype and speculators and grifters), Lower population (religions are opposed to it), degrowth (nobody wants to live a relatively substandard life, all the stuff is for status signaling), fly less, don't eat as much beef, etc. Degrowth is the best way, but nobody can walk entire population down that path. It has to be everyone or no one will do it because its all comparison based living. What are possible? 1) Plug-in solar and batteries: The next population boom is in Africa. Africa probably has the advantage of no legacy grid with fossil fuel interests and power plants. They can leap frog and go entirely offgrid or mini community level grids. 2) Vertical solar: Solar deployments at scale today use the legacy grid, production far away and transmission lines to bring power to cities. Solar is dirt cheap, the biggest costs now are land and transmission lines. Instead, we can do vertical solar in cities. Cover every surface. Adds ~4 hours of production every day. We already know rooftop solar works, with vertical, maybe cities can become self-sufficient. 3) EVs for energy storage. 1.8 billion vehicles in the world, if they all become EVs, they are the biggest energy storage without having to build a separate energy storage layer saving trillions of dollars. The first step is to stop buying ICE cars. It will take 20 years for the entire fleet to be electric. Solar is growing now, but curtailment is at 20%. Storage is the bottleneck. Solar will soon hit a wall, we can't grow solar because it becomes financially unviable to add more production, curtailment will increase and prices will go a lot more negative (500 million times/year in the US). People are going to buy cars anyway, we can't convince anyone to walk/bike, just have them buy EVs instead. This creates the storage to continue to grow solar.
