Before we move over to heat pumps and electric heating, a lot of work needs to be done on insulating homes.
A heat pump is not more efficient if you have to run it 24/7 to try keeping up with heat loss from single glazed windows and drafts from knackered doors etc.
I’m actually really looking forward to lab grown meat becoming an established industry. Not just for the benefits to the environment and animal welfare but because you could feasibly grow the finest lobster meat, fois gras, wagyu steaks etc etc on industrial scales which would lead to much lower prices.
You could even get in to really exotic meats like mammoth, platypus and giraffe or whatever else.
