The International Energy Agency (IEA) regularly conducts in-depth peer reviews of the energy policies of its member countries. This process supports energy policy development and encourages the exchange of international best practices and experiences to help drive secure, affordable and clean energy transitions.Belgium’s energy and climate policies push for energy transition through expanding renewable electricity generation and electrifying energy demand, especially for transport. Policies focus on maintaining affordable access to energy with the double aim of protecting vulnerable consumers and ensuring industrial competitiveness. Belgium has made notable progress on deploying offshore wind and increasing the share of electric vehicles. However, fossil fuels still dominate the country’s energy mix, a dependence that is expected to increase. All sectors have considerable work ahead of them to meet Belgium’s targets for increasing the share of renewables, lowering energy demand and reducing emissions.The IEA provides a range of energy policy recommendations in this report to help Belgium smoothly manage the transition to an efficient and flexible carbon-neutral energy system.
