Renewable energy sources (wind energy, solar energy, hydroelectric energy, ocean energy, geothermal energy, biomass, and biofuels) offer an alternative to fossil fuels and help reduce greenhouse gas emissions. They contribute to the diversification of energy supply and reduce dependence on volatile and fluctuating fuel markets, especially those for oil and gas.

Offshore wind turbines are a crucial component of the Belgian energy transition. The offshore wind farms (comprising 399 wind turbines) currently represent an installed capacity of 2,262 MW in the Belgian North Sea. They can generate an average of 8 TWh of green electricity per year, which is about 10% of Belgium's total electricity demand. By 2030, the offshore wind capacity in the Belgian North Sea is expected to grow to 6 to 8 GW (including the construction of the Princess Elisabeth zone at sea), which is about 30% of the electricity demand.

At the same time, the following technological innovations are being further developed: protection of critical infrastructure, floating solar energy, floating wind energy, wave and tidal energy, green hydrogen, and a sustainable plan for dismantling wind turbines.
