Frugal and Energy Efficient Living

It would require rebuilding the entire country. Abandoning millions of single family dwellings which would be inaccessible without automobiles, and building multi-unit complexes to replace them. Remaking the cities to be friendlier to walkers and bicyclists than to cars. Rebuilding a lost network of consumer services distributed throughout cities so that all the necessities of life are within a reasonable walkable distance of every apartment unit instead of centralized in a small number of big boxes. That would require remaking production and distribution chains. Even if everybody was willing and eager to change their mode of life to a more sustainable one, the effort necessary to make it possible for them would itself be a decades long carbon intensive project.
