9% of global electricity is generated from Nuclear

Nuclear energy is a powerful and efficient source of low-carbon electricity that has been harnessed since the mid-20th century. It is produced through nuclear fission, in which the nucleus of an atom is split into smaller parts, releasing a significant amount of energy. This process typically involves uranium or plutonium isotopes, which are used as fuel in nuclear reactors. Nuclear energy is recognized for its ability to generate a substantial amount of electricity continuously without emitting greenhouse gases during operation, making it an essential component in modern efforts to transition to a more sustainable, low-carbon energy mix.

The process of generating electricity using nuclear power starts with the fission of nuclear fuel within a reactor. When the nuclei of uranium or plutonium atoms split, they release heat. This heat is then used to produce steam from water. The steam drives turbines connected to generators, thus producing electricity. Similar to how fossil fuel plants operate, but with a crucial difference: nuclear plants generate electricity without the high carbon emissions linked to coal, oil, or gas. With an average carbon intensity of just 12 gCO2eq/kWh, nuclear power is comparable to other low-carbon sources like wind and solar, making it an environmentally friendly option to curb climate change.

Nuclear energy possesses the distinct advantage of low carbon emissions, in the same realm as wind (11 gCO2eq/kWh) and significantly lower than other sources such as coal (820 gCO2eq/kWh) or gas (490 gCO2eq/kWh). This makes nuclear an indispensable asset in reducing the carbon footprint of electricity generation, helping nations achieve climate goals. By ensuring energy is produced with minimal greenhouse gas emissions, nuclear power contributes significantly towards mitigating the adverse effects of climate change and improving air quality.

Globally, nuclear power generates approximately 9% of the world's electricity. This impressive share underscores its role as a substantial contributor to the global energy landscape. In some countries, nuclear energy makes an even more significant contribution: in France, for example, roughly 68% of electricity generated comes from nuclear power. Other countries, such as Slovakia and Finland, also rely heavily on nuclear, with it accounting for 60% and 38% of their electricity generation, respectively. These figures highlight the reliability and stability that nuclear energy provides, supporting national grids with consistent supply.

Furthermore, nuclear energy supports grid stability and energy security, essential components of a resilient energy system. Countries like Sweden, where nuclear contributes about 30% to electricity generation, and South Korea, where the contribution is around 31%, benefit from a robust and dependable supply of electricity. This reliability is particularly important as it aligns with the variability of other low-carbon technologies like wind and solar, ensuring a balanced and steady energy supply when renewable sources may fluctuate.

In conclusion, nuclear energy stands as a cornerstone of low-carbon electricity generation, alongside wind and solar. Its ability to deliver significant amounts of reliable, clean power positions it as a vital player in the transition away from fossil fuels, emphasizing its value in crafting a sustainable energy future. In enhancing global energy architectures, all countries should consider the strategic development and expansion of nuclear infrastructure to meet environmental commitments and support sustainable economic growth.
