I'm gonna be the annoying guy who points out the obvious thats being repeated again and again for the last 50 years...

For transport, trains! Trains of different sizes, shapes and designs, solve most of the transport issues. The fact that western countries are behind on this doesnt mean it's too late to start.

For heat, better insulation and heat pumps do wonders!

For feedstock maybe feeding animals is simply bot the way we should move forward.

And I say all this as a person who drives a gas car 70 miles every day, lives in an old house with bad insulation and eat meat several times a week
