The dynamic growth of renewable energy sources (RES) and accompanying digitalisation of the electrical grid creates new challenges for Poland’s and the EU’s security. The most important include securing supplies of raw materials for RES (photovoltaic panels, wind turbines) and ensuring cybersecurity for the energy grid. The importance of these issues will only grow with the ambitions of authoritarian regimes to control the supply of raw materials and cyberthreats posed by these regimes and non-state actors.
