PARIS — Expectations of a sharp rise in energy demand and the risk of climate change are pushing many countries to return to the idea of nuclear power, the head of the United Nations nuclear watchdog said on Monday.
Even the most conservative estimates predict at least a doubling of energy usage by mid-century, Mohamed ElBaradei, director general of the International Atomic Energy Agency (IAEA), told a conference on nuclear energy in the 21st century.
He said any discussion of the energy sector "must begin by acknowledging the expected substantial growth in energy demand in the coming decades."
It was unclear what role nuclear power would play, though it appeared to be an increasingly important one, he said.
"All indicators show that an increased level of emphasis on subjects such as fast growing energy demands, security of energy supply, and the risk of climate change are driving a reconsideration, in some quarters, of the need for greater investment in nuclear power," ElBaradei said.

"The IAEA's low projection, based on the most conservative assumptions, predicts 427 gigawatts of global nuclear energy capacity in 2020, the equivalent of 127 more 1,000 megawatt nuclear plants than previous projections," he said.
ElBaradei pointed to nuclear energy policy plans in China, Finland, the United States and possibly Poland as proof that nuclear power may be returning to vogue.
But he warned despite an improved atomic energy industry: "Nuclear power was dealt a heavy blow by the tragedy of the 1986 Chernobyl accident, a blow from which the reputation of the nuclear industry has never fully recovered."
The explosion at the Chernobyl plant in then-Soviet Ukraine, the world's worst civil nuclear accident, spewed a cloud of radioactivity across Europe and has been blamed for thousands of deaths from radiation-linked illness. More than 100,000 people had to be resettled.
On the topic of climate change and the threat posed by greenhouse gases, ElBaradei said nuclear energy in combination with renewable sources of energy represented a safe alternative to fossil fuels.
"Nuclear power emits virtually no greenhouse gases. The complete nuclear power chain, from uranium mining to waste disposal, and including reactor and facility construction, emits only 2-6 grams of carbon per kilowatt hour," he said.
"This is about the same as wind and solar power and one to two orders below coal, oil and even natural gas."
