The benefits of nuclear energy

The world is in a state of flux, with a succession of extraordinary crises: global pandemics, conflicts, energy crises, inflation. More than ever, we need to assert control over our energy security and independence. We must also act to "decarbonize" electricity production, which is the world's primary source of carbon emissions, due to the use of fossil fuels (coal and gas). Nuclear energy is a dependable solution for ensuring our sovereignty and combating climate disruption.

Nuclear energy: a low-carbon solution



Nuclear is one of the world's least CO2-emitting forms of energy, with emissions comparable to wind power, 4 times lower than solar power, 40 times lower than gas and 70 times lower than coal. Its very small CO2 footprint makes it an indispensable energy for the low-carbon energy transition.

Nuclear energy and energy sovereignty

Continuous, controllable electricity


constante pilotable

Thanks to its robust production system, nuclear energy delivers large quantities of electricity continuously, while adapting to demand. In this way, nuclear energy makes a major contribution to safeguarding the supply of electricity to hospitals, to homes and businesses, as well as for transportation, the world over.

When we flick a switch and the light comes on instantly, it's a good example of what continuous nuclear electricity does for us.

Uranium: high energy density



Because uranium has a much higher energy density than hydrocarbons (100g of uranium produces as much energy as a metric ton of oil), it can be stored more easily. France has several years' worth of stockpiled depleted uranium. Moreover, uranium is an abundant resource available on all five continents.

Nuclear energy: an energy source that saves raw materials



Orano recycles nuclear fuel to produce new fuel, thus helping to preserve natural resources. In France, one in every 10 light bulbs works on energy generated using recycled nuclear fuel, MOX.

96% of used fuel can be recycled, so that natural resources can be saved

Nuclear energy, essential for the electricity mix

In all the energy transition scenarios studied by the IPCC1 and the IEA2 for the production of low-carbon electricity, a significant development of renewable energies can only be envisaged along with nuclear power to avoid the use of fossil fuels. Renewable energies (solar, wind) are by nature intermittent and cannot meet the existing and future energy needs of 8 billion people on their own.

As a result, nuclear and renewables must combine together to sustain the low-carbon energy transition and meet France's commitments to combat global warming.

Coal was the energy source of the 19th century, Oil that of the 20th. Carbon-free electricity will be that of the 21st century.


A resource for the future


Ressource pour le futur

Over the past 50 years, the nuclear industry has been developing expertise and technologies that are unique, enabling us not only to produce the energy of tomorrow, but also to advance other sectors of human endeavor including health (cancer therapies), resource efficiency (recycling of strategic metals/materials), space research and more.
