heat them with compost! green houses can save transport mileage for fresh extended seasonal produce.

lotsa carbon saving tucked in there... lighting and irrigation wouldn't be hard to power locally, with some biogas or wind/solar/batteries.

thinking local, thinking small and many, robustness through decentralisation...

That is in fact how I heat my greenhouse, but I found I needed more biomass that my greenhouse produced.  So it wouldn't scale.  There are also issues with mould and botrytis, and I have a very moderate heating climate compared to europe.

I agree in principle anyway.
