The market, technology and policy foundations are in place for a new era of growth in nuclear energy over the coming decades. Demand for electricity is rising fast, not only for conventional uses such as light industry or air conditioning, but also in new areas such as electric vehicles, data centres and artificial intelligence. Electricity use has increased at twice the rate of total energy demand over the past decade and is set to extend this lead as the world enters a new Age of Electricity. Nuclear is a clean and dispatchable source of electricity and heat that can be deployed at scale with round-the-clock availability. It brings proven energy security benefits to electricity markets as well as reductions in emissions, complementing renewable energy. Interest in nuclear energy is at its highest level since the oil crises in the 1970s: support for expanding the use of nuclear power is now in place in more than 40 countries.
