Italy ended its nuclear programme after a 1987 referendum, and voters rejected revival plans in June 2011. In September 2026 the Senate gave final approval to an enabling law that delegates to the government the design of a national sustainable nuclear programme and a new independent safety authority. Policy position as read on 2026-11-03: World Nuclear Association, Nuclear Power in Italy (page dated 2026-05-18); World Nuclear News, Italy's Senate approves a return to nuclear power (page dated 2026-09-24).

Share of electricity from nuclear power

In Italy, nuclear plants generated 0.0% of electricity in 2025, about the same as 0.0% in 2015. The share peaked at 4.6% in 1986, so it is 4.6 percentage points below its high.

Share of the country's total electricity generation that came from nuclear plants, by calendar year (1985 to 2025). Amber marks the high point, green the latest year. Source: Our World in Data from Ember and the Energy Institute, CC BY 4.0.
