Yeah. Except that just building the factories to build the solar panels and wind turbines would take longer than that. And that statement ignores the whole supply chain.
The thing is, despite what extinction rebellion et. al. tell us, the global economy is moving to renewables pretty much full speed. It's just that that same economy has so much inertia that it will take decades to make that switch. But the second half will not take nearly as long as the first.
- thefz 4y ago> The thing is, despite what extinction rebellion et. al. tell us, the global economy is moving to renewables pretty much full speed. No, no. Until there's still a drop of oil or a lump of coal to exploit, there will be no "full speed". Corps want you to believe they are thinking green, while they just don't care. Events like the energy crisis in Europe might open a few eyes, but nothing more.

- choeger 4y agoPrices and lead time for solar power projects. Right now, solar power is a no-brainer for pretty much everyone in the industrialized world. No one does not invest into solar because they're stubborn or stupid. The pipeline is simply sold-out. It's similar for wind power, but somewhat distorted by the very long time it takes to build a wind farm (from planning to first watt-hour). Notably, noone can put a wind turbine on their roof.

Our bottleneck right now is processing, not mining (because of the energy crisis).
- yongjik 4y agoYeah I very much doubt that. Until last year, the energy policy of Germany, one of the richest countries in the world, depended on cheap gas from Russia. It took Russia's invasion of Ukraine to force them to reassess their policy. And their short-term solution? Buy gas from other countries.
- TheLoafOfBread 4y agoAgree Energiewende is dead end, because Germany is missing energy storage to fill out intermittencies, which is now substituted by gas. And that energy storage kind of does not exist. (aka something what can keep lights on in whole country at least over night, not few minutes like batteries)
- bjourne 4y agoIf it is one thing I've learned from Hacker News it is that the gut feelings and knee-jerk reactions of anonymous posters always and invariably trump whatever "researchers" publish in their peer reviewed so called "journals".
- TheLoafOfBread 4y agoLike being spammed around 2015 that self driving will be common around 2020 or electric cars cheaper than ICE any moment. BEVs are now more expensive than ever, expected to suffer battery shortages for next decade and are economically unviable thanks to expensive energy.
- karmakurtisaani 4y agoNot sure if you're aware, but the first self driving taxis are publicly operating in San Francisco.
- TheLoafOfBread 4y agoI am aware of that, and they are more than useless. https://www.thedrive.com/news/a-swarm-of-self-driving-cruise-taxis-blocked-san-francisco-traffic-for-hours https://www.thedrive.com/news/a-swarm-of-self-driving-cruise...
