Where are we now? We are already doing a lot to save energy as well as switching to natural energy sources. A good example of this is the DaglichtKas (Daylight Greenhouse). Special lenses in its roof concentrate the rays of the sun onto a tube containing running water. The focal line this creates heats the water in these tubes. The heat can be used to warm the greenhouse either straight away or at a later point. This enables us to use 40–50% less energy! We also use solar panels, LED lighting, heat pumps, Next Generation Growing and ground-coupled heat exchangers.
Goal for 2030: Fossil-free cultivation
How will we tackle this? For fossil-free cultivation, reducing energy consumption in greenhouses and switching completely to green energy sources is crucial. We determine the perfect energy mix and work towards it step by step. Doing so requires time, research and investment. We are, among other things, affiliated with a geothermal energy project that is under development. Geothermal energy is a sustainable and clean source of energy that involves pumping hot water from deep in the ground. This heat can be used to heat our greenhouses. The cooled water is then pumped back into the ground. We are also exploring options such as solar, wind and hydrogen energy.
