The EU depends on imported fossil fuels (gas, oil and coal) for about 56 % of its energy needs (gross energy consumption), which in 2021 represented an energy bill of around EUR 300 billion. The domestic production of renewable energy sources has increased significantly in recent years to 22 % of total demand. The European Union can aspire to achieve energy independence through the deployment of existing and emerging technologies. Electrification, renewables and energy storage could reduce EU's reliance on conventional fossil fuels. What are the developments, expectations, concerns and societal implications associated with these technologies? What initiatives and policies can lead to a resilient EU energy system by anticipating impacts?
