1. The role of grids in Europe is important for developing renewable energy sources because building an integrated European grid capable of distributing both large-scale and distributed renewable generation is necessary to achieve full decarbonization of the European power sector and meet energy security targets, according to studies. 2. Environmental regulations and timely grid expansion can be reconciled by following principles set out in the European Grid Declaration signed by environmental organizations and grid operators to build new infrastructure with full respect for the environment. 3. Public acceptance of new grid infrastructure is difficult to achieve but critical for the energy transformation; getting stakeholders involved in decision making and learning from past experiences on public engagement can help, according to RGI.
