Close the Bloody Door

I walked into a local branch of Clarks at the weekend and I'm starting to get a little upset about these shops that have wide open doors and warm air curtains, or air curtains, as I believe they're called. Here's us being taxed to reduce carbon output and shops go wasting energy by heating the street outside.

The Close the Door campaign says that simply closing the door not only contributes towards the national target of a 34 per cent reduction in carbon emissions by 2020, but also slashes a shop's energy usage in half. The research suggests that if all retailers followed their advice UK energy usage could drop by 2.5 per cent.

The retailers' argument is that they'd lose footfall and hence profits. I'd like to see some analysis of potential lost profits verses the cost of the additional electricity through a trial.
