> There’s huge lie (by omission) about renewables: nobody explained how to convert the world to 100% renewable energy without coal backup.
Because not everywhere in the world has access to hydroelectric power. The point remains: there is no plan to power the world with renewables without a fossil fuel backup. At least not any feasible plan - batteries don't scale, and the Sabatier processes has well below 50% round trip efficiency.
You don't need a plan to power the world. Try a plan to power your own state and let the rest of the world sort itself out. When you're at 80% renewables and then get stuck, then I'll believe it's an issue. Not when you're at 20% and handwaving theoretical excuses.
I live in Scotland. We now get around 90% of our electricity from renewables. We closed our last coal power station in 2016.
Perhaps you should consider checking your theories against reality before accusing others of lying?
