«In Ruswil, a natural gas derisification plant is being operated as a part of the European gas-pipeline network. The plant generates more than 100 GWh (1 GWh = '000 kWh) waste heat per year. Options to use this energy to heat villages failed due to cost reasons. Today 40 GWh of the waste heat are turned into ecologically sound electricity and up to 30 GWh will be used for the production of tropical fruit and fish as a contribution to substitute energy consuming imports».
