the thing #doomers obsess about with entropy is about how non-fossil fuel energy is A LOT less energy (or power) dense than sunlight, which basically fuel renewables. very complex life, like humanity, can only feed on sources of sufficiently high energy density, so long story short, transitioning to renewable energy goes against the rules of life, if you will.
the thing is, whether or not i, or anyone agrees - doesn't really matter, right. point is STILL: we have to use less.
