Industry heavy enough to create turbines and multi-GW solar arrays is no more energy-demanding than other industries that were localised a century ago.

It's not the energy demands that make me call it heavy industry. It's the fact that we're talking about rotor blades the size of large aircraft wings, and of advanced materials in the case of photovoltaics. Both of those require large, complex facilities.

But your point on energy is important also in another respect: modern industrial technology is way more efficient in its use of energy and material resources than "traditional" production methods. That's what technological progress is about. It's not only improvements in final products but in every intermediate step of production.

And that, my friends, is why rolling industrialization back is definitely not the answer to resource constraints.
