Indeed it is possible to grow more exotic produce in northern climes, which is why (strangely) most of our peppers come from Holland a country with a similar climate to us, they use huge heated greenhouses to achieve this, I'm not sure how green this is.

Almost always three times as green as you think it is.

Firstly they generally use water that has been heated through an industrial process as the method of heating.
Secondly by using the heat from that water it allows it to cool to a point where it can be classed as acceptable to return to the water course through standard sewerage systems eliminating the need for energy intensive water treatment and cooling plants.
Thirdly because the source of that water is commonly a renewable energy/carbon neutral energy generation source such as CHP.

Potentially greener than British Peppers, even with the food miles and far better than the Israeli alternative as they don't massively oppress half their workforce and use profits to massively oppress their neighbours.
