Nuclear energy is a powerful, low-carbon form of energy that utilizes the principles of nuclear physics to generate substantial amounts of heat and electricity. This unique form of energy is harnessed from the process of nuclear fission, where atoms such as Uranium-235 or Plutonium-239 are split into smaller atoms, releasing an enormous amount of energy. Distinct for its high energy density, nuclear energy is a potent form of low-carbon energy source with an exceptional capability of generating electricity on a larger scale.

The generation of electricity through nuclear energy primarily involves the process of nuclear fission. In this process, neutron particles strike the nucleus of a heavy atom causing it to split and release a great deal of heat energy in the process. This heat is then captured and used to generate steam, which drives a turbine connected to an electricity generator, thereby producing electricity. This form of energy conversion is not only powerful but also remarkably clean, with the carbon intensity as low as 12 gCO2eq/kWh, significantly less when compared to fossil fuels which hold considerably large carbon intensities.

One of the primary advantages of nuclear energy is its low carbon emissions. Unlike fossil fuels, which have a carbon intensity ranging from 490 to 820 gCO2eq/kWh, nuclear energy averages only 12 gCO2eq/kWh. This makes nuclear energy an effective solution for forward-thinking countries eager to reduce their carbon emissions and combat climate change. Alongside other low-carbon sources such as wind and solar, nuclear energy represents a key component in a diverse and sustainable energy strategy for the future.

Another significant advantage of nuclear energy is its contribution to global electricity production. As of now, nuclear energy generates an impressive 9.23% of all electricity consumed globally, clearly showcasing its capability as a reliable energy source. This percentage is even higher in certain countries. For instance, in France, nuclear energy is used extensively to generate a significant 66% of the nation's electricity while in Finland, it contributes to 42% of their electricity production.

In other parts of the world, nuclear energy also plays a crucial role in power generation. In Sweden, nuclear power contributes 30% of the country’s total electricity, while Slovakia utilizes nuclear power to generate a hefty 61% of its electricity. Even in South Korea, 29% of the nation's electricity is produced through nuclear power. These examples highlight the considerable potential of nuclear energy as a significant player in the global electricity landscape, when responsible strategies and regulations are put in place.

Along with wind and solar power, nuclear energy offers a low-carbon and sustainable solution to the world's growing energy needs. By embracing these technologies, countries are not only reducing their carbon footprint but also paving the way for a greener and sustainable future. For this reason, more investment and research into these low-carbon energy technologies are vital to meet our global energy demands while preserving our planet.
