past decade, Swedish greenhouse cultivation has seen a continual structural and
energy use transformation. As the number of holdings and the cultivated area
has decreased, energy use has been reduced, streamlined and has changed
character. The present report is a description of the current energy use
pattern in the Swedish greenhouse business, as well as an overview of changes
since 2002. The focus lies on the – from an area perspective – major branches:
tomato-, cucumber- and ornamental plant cultivation. Between
2002 and 2011, the number of Swedish commercial greenhouse holdings has been
reduced by 40 %, while the cultivated area has decreased by 12 %. During the
same period, energy consumption for cultivation has been reduced from about 1,2
TWh to just over 0,6 TWh. The relatively large decrease in energy consumption
as compared to cultivation area, signifies an increased energy efficiency. For
the entire greenhouse cultivation, energy consumption was reduced from 371 to
215 kWh per square meter during the 2002–2011 period. For the specific
branches, the decreased amounted to 21 %, 54 % and 58 % for tomato-, cucumber
and ornamental plant cultivation, respectively. The use of
various energy sources exhibited a distinct alteration between 2002 and 2011.
The share of fossil fuels decreased from 77 % of the total energy consumption in
2002, to 43 % in 2011. Meanwhile, the share of biofuels increased from 5 % to
37 % of the energy used. Tomato- and cucumber cultivation exhibited a biofuel
share of 55 % and 56 %, respectively, while the use of biofuels in the
cultivation of ornamental plants reached 31 %. Holdings exhibiting different
energy source use profiles also exhibited some general differences regarding
cultivation branch, geographic location, greenhouse size and use of materials. Even as the
change in direction towards a higher share of biofuels in the energy mix
appears clear, changes on a holding level are more complex. While 95 holdings
increased their share of biofuel use between 2008 and 2011, 61 holdings
simultaneously decreased their share. During the same period, 161 and 140
holdings increased their share of fossil and miscellaneous energy sources,
respectively, while 174 and 172 holding decreased their share of the these
energy sources. List of tables
