An energy pathway needs be formed in order to improve the greenhouse performance by reducing the direct energy inputs and conserve energy throughout the system. This paper has assessed such pathways including single and combined opportunities to improve energy performance in the commercial greenhouses, with special emphasis on Nordic climates. The present situation show that the total energy use in Swedish commercial greenhouse has increased by 50% on average between 2008 and 2011. However the heating oil consumption has been reduced by 18%, while the biomass usage has been increased by 45%.
