I really don't understand the point of this essay. No one believes that renewable energy will solve all problems nor get humanity out of the predicament that we are in. However, renewable energy technologies are much better than fossil fuels, and offer many benefits as we transition. As we all know, humans are in massive overshoot, we will soon run out of economical fossil fuels, and we have 10x (more likely 100x) too many humans on the planet. We must depopulate as quickly as possible, while using the remaining fossil fuels for the most essential applications, and we must transition to an all electric future using renewables. Meanwhile we can take hundreds of other common sense steps (no more road building, ban fireworks, limit fast fashion, micro mobility, redesign towns, etc etc). Eventually the world may be back to a global population of 10 to 100 million, but we have to survive a long and difficult transition period to get from here to there. Renewable energy can play a critical role in this, but it is just one piece of a complex puzzle. Depopulation is fully required or we are just kidding ourselves. No serious person believes that we can switch to renewable energy and then continue with business as usual with 8+ billion people and growing. That is clearly a recipe for catastrophe and a very brutal ending for the human race.
