The sustainable energy system of the future will be more complex than the system we have today. It will be a system filled with sustainable electrons and sustainable molecules. There are two potential ways forward for us. The large-scale roll-out of offshore wind in the decades to come will lead to a major green energy source becoming available that will chiefly be able to supply the sustainable centres of industry in the Netherlands with energy. Kicking off the development of this "Green North Sea Powerhouse" requires a systematic and planned approach beyond 2030, comparable to the Delta Works. On the road to 2050, growth up to 60 GW of established capacity may be achieved, depending on the national and international demand for electricity. This requires effective communication with all stakeholders, including coordination with other North Sea countries, with a view to establishing a reliable and affordable energy system and a combined objective of a sustainable economy, safeguarding and, where possible, reinforcing the ecological value of the North Sea. In addition, the future will feature options such as the expansion of interconnection, conversion to hydrogen or other energy carriers, greater flexibility on the demand side, smart grids, storage and artificial islands in the long term, with a view to cost-effective integration of more offshore wind energy. On land, the situation will be virtually mirrored, with citizens (such as "prosumers"), districts, public authorities, public institutions, network and other operators, businesses and civic organisations collaborating on an extensive web of local and regional, small and larger
