The heating and cooling system of the hospital in Kristianstad uses energy from an aquifer in order to heat the hospital in winter and cool it in summer. This is a unique clean energy solution that uses “free energy” in a creative way. The solution was developed by Region Skåne in cooperation with the company Malmberg Water.

Arlanda Airport has managed to reduce its emissions of carbon dioxide with 50 %. A strong contributing factor to the reduced emissions has been the investment in geo energy, which is taken from an underground aquifer.
