While 32 countries generate atomic energy, nine have nuclear weapons and seven countries have both.

With the 26th UN Climate Change Conference over, nations are making plans to move to green energy in a bid to tackle global warming.

But nuclear energy is a particular sticking point. While it is the largest source of low-carbon electricity in OECD countries, some nations have spoken out against the categorisation of nuclear energy as climate-friendly.

Across the globe, 34 countries harness the power of splitting atoms for generating electricity or for nuclear weapons.

GLOBAL NUCLEAR ENERGY

Nuclear energy provides roughly 10 percent of the world’s electricity. Of the 32 countries with nuclear power reactors, more than half (18) are in Europe. France has the world’s highest proportion of its electricity – at 71 percent – coming from atomic power.

Up until 2011, Japan was generating some 30 percent of its electricity from nuclear reactors; however, following the Fukushima disaster, all nuclear power plants were suspended for safety inspections. As of 2020, just 5 percent of Japan’s electricity came from nuclear power, according to the World Nuclear Association.

Nuclear power constitutes some 20 percent of the United States’ electricity. About 60 percent of the country’s energy comes from fossil fuels, including coal, natural gas and petroleum, with the remaining 20 percent coming from renewable sources – wind, hydro and solar.

NUCLEAR WARHEADS PER COUNTRY

Nine countries possessed roughly 13,150 warheads as of August 2021, according to the Federation of American Scientists. More than 90 percent are owned by Russia and the US.

At the peak in 1986, the two rivals had nearly 65,000 nuclear warheads between them, making the nuclear arms race one of the most threatening events of the Cold War. While Russia and the US have dismantled thousands of warheads, several countries are thought to be increasing their stockpiles, most notably China.

According to the Pentagon’s 2021 annual report, China’s nuclear warhead stockpile is expected to more than triple and reach at least 1,000 by 2030.

The only country to voluntarily relinquish nuclear weapons is South Africa. In 1989, the government halted its nuclear weapons programme and in 1990 began dismantling its six nuclear weapons. Two years later, South Africa joined the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) as a non-nuclear country.

TREATY ON THE NON-PROLIFERATION OF NUCLEAR WEAPONS

Established in 1968, the NPT aims to prevent the spread of nuclear weapons and promote the peaceful use of nuclear energy.

The treaty bans signatories other than the US, Russia, China, UK, and France from acquiring nuclear weapons in return for allowing them to pursue peaceful nuclear programmes for power generation, overseen by the UN.

As many as 190 nations are currently signed up for the treaty, with only India, Israel, Pakistan and South Sudan never being a party to it. North Korea signed the treaty in 1985 but withdrew from it in 2003. Three years later, under the leadership of Kim Jong Il, the country detonated its first nuclear weapon.
