Monitoring the Dutch Bulbous Industry in 2019 by WUR showed the weighted averaged energy use per unit (per cropped area and per 1000 flowers) was reduced with 21.4 % compared to 2008. Thus, the Energy-Efficiency Index (EEI) resulted in 100 – 21.4 = 78.6. The target of an EEI reduced to 75.8 has therefore not been realised. Up to 58% of the flower bulb companies use renewable electricity which represents 26,2% of their total electricity use. In addition, 4087 MWh is delivered to the energy net (7,4% of the total use). Solar panels, installed by 42% of the companies in 2019 (against only 0,2% in 2008), produced 12 %. Renewable thermal energy is used on 47% of the companies, representing 2,6% of the annual use of the industry. In 2008 it was used by 14% of the companies, representing only 0,6% of the annual use. Particularly the use of solar heat collectors increased, from 1,0% of the companies in 2008 to 13,4% in 2019, covering 1,6% of the thermal energy use.
