Which ones?

We prefer to use the most sustainable energy sources: we are systematically switching over from fuel oil to gas, adding some electricity to the mix that we generate ourselves, and making more and more use of biomass every year. We install energy shields in the greenhouses, we clean the greenhouse roofs to allow the maximum light in, and we are beginning to plant later so as to avoid the coldest months. As Responsibly Fresh growers, we are pioneers of green electricity: we use combined heat and power, solar panels, ground heat, wood-burning, biogas installations, heat pumps or solar water heaters. Our producers' cooperatives also make use of combined heat and power and have fitted solar panels on their sheds.
