historically cheap energy has lead to - surprise - more energy being used.

use less energy, period. ideally yes, the energy should be renewable and not cause harm to the environment as well.

I would argue that it's easier to switch energy completely to renewables than to significantly cut global energy usage. It's also more ethical solution than forcing people to live in tiny apartments and preventing them from traveling.

I'd argue that it's easier to increase energy consumption and not to worry about pollution at all, but it's not about what's easier unless you're holding the consequences constant.

What does this have to do with ethics? Is "more ethical" when you bother people less?

There is nothing wrong with using lots of energy if it’s green! We should be using more energy, not less! Energy is amazing. We just have to make it from non fossile sources.

Promoting clean energy isn't mutually exclusive with reducing consumption (at least in the short-term, until clean energy is both the norm and in surplus).
