The transition from fossil fuels to bio-fuels in Swedish greenhouses has gone fast. For the cultivation of ornamental plants and cut flowers in Swedish greenhouses, the use of fossil fuels has dropped from 460,000 megawatt hours to just 32,000 hours in a few years. That's a decrease of more than 90 percent.
Since 2002, the total energy consumption per m2 for the cultivation of ornamental plants and cut flowers has dropped by more than half. In addition, 60 percent of the energy in flower greenhouses is now derived from bio-fuels. The sharp fall in energy consumption is largely due to the fact that new greenhouses are much more energy-efficient than the older ones and that the use of climate screens has increased considerably.
