Over winter tomatoes were in short supply, not because we couldn't grow them, but because the methods of heating greenhouses were too expensive. CO2 heaters use gas in largely uninsulated greenhouses. A bit of creativity (solar thermal with storage supplying radiators) or just modernity (air source heat pumps) would have solved this problem.
Alas, there is little guidance and support. The economic case for fossil fuels continues to weaken and the government does absolutely nothing to support a transition to cleaner sources of fuel which provide shelter from the volatility of energy markets. So we pay instead.
What absolute rot.
