To meet the growing demand for reliable, affordable and clean electricity, the world needs all low-carbon energy sources to work together as part of a diverse mix. Achieving this means nuclear energy generation must triple globally by 2050. The nuclear community needs to meet this challenge. Harmony provides a framework for action, working with key stakeholders so that barriers to growth can be removed.
Access to electricity and the need for clean air are vital. Electricity consumption continues to rise but air pollution and greenhouse gas emissions must fall. The Harmony goal is developed from the International Energy Agency’s 2C scenario, which sets out a pathway that avoids the most damaging consequences of climate change and requires a large increase of all low-carbon sources, of which nuclear is an important part.
Nuclear generation is a cost-competitive low-carbon generation option according to the IEA World Energy Outlook 2016. The cost per unit of electricity produced from wind or solar PV is stated to be 22-40% higher than that from nuclear generation, even without counting the additional costs of adapting the grid and providing the backup generation required to compensate for their intermittent supply.
The build rate required to meet the Harmony goal of 1000 GWe of new nuclear capacity by 2050 is:
• 10 GWe per year between 2016 and 2020
• 25 GWe per year between 2021 and 2025
• 33 GWe per year between 2026 and 2050
The Harmony goal is ambitious but crucial for the world to meet the energy challenge. It has been established in 2016 by the World Nuclear Association and is gaining traction in the global energy arena. Achieving 1000 GWe of new nuclear build by 2050 will require a cooperative effort by the whole nuclear community – from industry to research, governments, and regulators – to focus on demolishing the real barriers to growth.
