Electricity from wind and solar energy plays the central role in all ambitious expansion scenarios.

A solution is urgently needed, as the demand for electricity will increase sharply due to the switch to e-mobility and zero-emission industry.

In order to achieve security of supply even with increasing consumption, attention must therefore be paid at the same time to efficient use of resources and circular economy systems.

Studies on electricity supply in Europe, which focus on the future contribution of large-scale power plants to the generation of renewable energies, assume that wind energy will be the most important. Its contribution could account for up to 49 % of European electricity demand by 2050. Solar energy is expected to account for 16% to 35%, while hydropower and electricity from biomass are far behind at 10% each.

For a long time, the motto was: "Steel will play an important role in all renewable energies, especially solar and wind energy. For every new MW of solar power, between 35 and 45 tons of steel will be needed, and for every new MW of wind power, 120 to 180 tons of steel." 

Today, it's the other way around: "Renewable energies will be the key to truly green steel production."
