To meet the growing demand for sustainable energy, we will need nuclear to provide 25% of electricity before 2050 as part of a clean and reliable low-carbon mix. Achieving this means nuclear generation must triple globally by 2050. The Harmony programme is a global initiative of the nuclear industry that provides a framework for action, working with key stakeholders so that barriers to growth can be removed. Why we need Harmony An increased share of low-carbon sources, as well as a drastically reduced level of fossil fuels, work together in harmony to secure a reliable, affordable and clean future energy supply 24 hours a day.
