It's better to consume very few electricity, produced from nuclear for example, than setting up solar energy (with a significant loss on conversion and a footprint in materials, as well as nuclear plants, but what I mean is it's more our lifestyle that matters rather than the solutions themselves

Indirectly consuming few electricity means you've few devices which also have a number of footprints, so it's quite a large gain

The only counter example to what I said is maybe buying land to convert it to a food forest / permaculture, and save it from another guy building a villa with swimming pool
