If you're already well off (like most HN posters, probably) then you might not care if the leader of your country tells you that you will have to reduce your standard of living for the sake of the environment (and keep in mind that they rarely make those claims based on realistic analyses). If you are barely making ends meet and don't know if you will be able to retire after toiling your whole life like many people it is a harder sell. For example, where I live my electricity provider is harassing me to switch to "clean" energy sources, coyly admitting that the price will be higher in fine print. Turns out they entice people to join only to increase their prices later (see https://www.thedailybeast.com/cleanchoice-energy-is-the-snea...). Can you afford to pay double or triple the price for energy? What if you had to? Some of us cannot afford to run air conditioning at a certain price.
Some still think that this is a mere "conspiracy theory", but the messaging is slowly becoming more explicit about this power grab. I'm talking about some national government figures talking about lowering your standards out loud. Less obvious tells are organizations connected to governments setting lofty "sustainability" goals which involve reducing energy footprints to a level that is impossible to achieve without significantly impoverishing nations. Farmers forced to reduce their use of nitrogen fertilizer are the appetizer.
