proportions at Hjortebjerg is the energy bill. As at all other greenhouses in Denmark, it takes a great deal of both light and heat if you want to earn profits all year round cultivating fruit, vegetables and potted plants indoors. At Hjortebjerg, they constructed their owm CHP (central heating plant) in 1996 as the heating demand was so heavy. "At the time there was a policy to decentralise energy production, and we could see the sense in that," says Steen Juul Thomsen, managing director of the family-owned greenhouse. But with the increasing level of environmental awareness in the nineties, the energy consumption of the greenhouses was to become an ever-hotter political potato. Consequently, in 2000, the Danish greenhouses entered into an agreement with the Ministry of Energy to monitor their energy consumption and ensure that they could both maintain their production levels and save energy. This meant increasing awareness:
With a share of around one percent of Denmark's total energy consumption, the Danish greenhouses occupy a sensitive position in the climate debate. a pilot project at a giant greenhouse in Funen aims to both drastically reduce the energy consumption of the nurseries, and to add energy to the list of crops that can usefully be harvested in Danish greenhouses.

Hjortebjerg Greenhouse just outside the town of Bogense in north-west Funen, is very large covering six hectares more than 55,000 square metres under glass, it is one of the five largest in Denmark. It is so large that the crane which transports the trays of plants around in the greenhouses is fitted with a laser sight so that the operators can find out where they are. The building is so enormous that it expands in the heat. Another thing which takes enormous
