The popular idea that we can use mostly or all solar/wind with sufficient battery backup is not being tried anywhere because it’s economically absurd. Batteries are so expensive that just 3 days of global backup using @elonmusk’s Megapacks would cost $400T, >4X global GDP. — PolitiTweet.org

Solar and wind’s basic problem is unreliability, to the point they can go near-0 at any time. Thus they don’t replace reliable power, they parasite on it. This is why they need huge subsidies and why no grid is near 50% solar/wind without huge parasitism on reliable neighbors. — PolitiTweet.org

For solar/wind to rapidly replace fossil fuels would require magically, immediately fixing their intractable problems providing electricity, then providing the 4/5 of world energy that isn’t electricity, then doing that for the world’s far greater energy needs going forward. — PolitiTweet.org
