    Abstract

    The opportunities to significantly reduce the electricity consumption in an illuminated strawberry cultivation
    has been analysed in a desk study. Special energy-efficient LED lamps can be used to steer plant growth and
    development. By replacing HPS-lamps by the latest LEDs with an energy efficiency of 2.7 μmol/W, the power
    consumption can be reduced by more than 30%. It seems possible to reduce this consumption in illuminated
    strawberries by another 10% in a greenhouse with high light transmission in the winter months and using
    artificial lighting more in relation to different growth stages. Light colour (spectrum) affects the growth,
    production and quality of strawberries. A high amount of red light stimulates production and blue light enhances
    the sugar and vitamin C content.
    The light and energy consumption can be further decreased by improved space utilization and by reducing the
    leaf/fruit ratio. Gas savings are possible by minimizing the use of the minimum heating pipe and closing the
    energy screen during cold weather. However, this requires special attention with respect to the prevention of
    fungal diseases and maintaining fruit quality.
