Welcome to 100TWh

Nuclear, the energy of the future

Nuclear power plants in Belgium are responsible for the production of the majority of our electrical power. Nevertheless, the government has voted to shut down these power plants by 2025. Because there is no viable alternative to replace the total output of nuclear power plants, this will greatly affect the price we pay for our electricity.

As the consequences of climate change are becoming more and more real, any solution to our energy needs should be contingent with the aim for Belgium to be carbon neutral by 2050. Did you know that nuclear power plants are almost completely carbon neutral already?

At 100TWh, which stands for the projected electrical energy needs of our country in the near future, we want to ensure that our nuclear power plants remain operational after 2025 to guarantee an affordable and carbon neutral energy production!
