In a commentary for the journal One Earth, energy economist Claudia Kemfert from the German Institute for Economic Research (DIW) and Jan Rosenow from the NGO Regulatory Assistance Project (RAP) have outlined five strategies for managing the reduction of gas networks as the use of natural gas in Europe decreases. According to their projections, the demand for natural gas will decline by up to 70 percent by 2050. Without accompanying political measures, network charges in Germany could quintuple in the next 16 years.
