I’m skeptical of demand reduction. History shows that we keep finding more ways to use energy to improve our lives. We’re unlikely at a global scale to reduce lifestyle to reduce energy usage. We’ve got a big enough problem here with meat eating, where there isn’t a substantially lower carbon option and we’ll probably just have to move to more plant based diets.

For energy consumption it seems much easier to me for us to replace energy generation with green alternatives. I was skeptical of this 10 years ago, but we’ve since seen huge rollouts of wind and solar, the near phasing out of coal in many countries, and continually dropping prices for the necessary hardware. We need to accelerate these, but this feels feasible.
