9% of global electricity is generated from Nuclear

9.27 % Share of global electricity
12 gCO2eq/kWh Carbon Intensity

Nuclear energy is a low-carbon, clean and sustainable form of power generation. It harnesses the power trapped within the nucleus of an atom to meet our growing energy demands. Emissions from nuclear power generation are incredibly low with an average carbon intensity of just 12 gCO2eq/kWh. This rests at the lower end of the scale compared to other energy sources, marking nuclear energy as a green and environmentally friendly power solution.

The process of generating electricity from nuclear energy primarily involves a process known as nuclear fission, where the nucleus of a heavy atom such as uranium or plutonium, is split into two or more smaller nuclei along with some by-products. The by-products include a huge amount of energy in the form of heat and radiation, which is harnessed to generate electricity. Nuclear power reactors heat water to produce steam, which is then used to turn turbines that generate electricity.

Among the many advantages that nuclear energy offers, one of the key benefits is its substantial contribution to global electricity consumption. Nuclear power provides 9.27% of all electricity consumed globally, making it a significant player in the world's energy mix. Its low-carbon attributes combined with its high energy yield have made it a preferred choice for many nations looking to reduce their carbon footprint.

In several countries, nuclear energy constitutes a major part of their electricity generation mix. For instance, Finland generates 42% of its electricity from nuclear power, emphasizing their commitment towards green, sustainable energy. In France, the world's largest net exporter of electricity, nuclear power makes up a whopping 66% of their electricity production, demonstrating an impactful application of this low-carbon technology.

Additionally, in Sweden, which is known for its commitment towards greenhouse gas reduction, about a third of its electricity is generated from nuclear power. Neighboring Slovakia also leans heavily on nuclear energy, deriving 61% of its electricity from it. Both countries serve as strong examples of how reliance on nuclear power for electricity generation can help nations decrease their carbon intensity.

South Korea, a country earnestly working towards diversifying its energy mix, derives 29% of its electricity from nuclear power. This stands as a testament to how countries can effectively incorporate nuclear energy into their broader energy strategy to realize their environmental goals.

In conclusion, nuclear energy showcases significant advantages with its low carbon intensity, substantial global contribution to electricity consumption, and heavy utilization in numerous countries committed to environmental sustainability. Alongside other low-carbon, clean energy sources such as wind and solar, nuclear power forms a crucial part of our global green energy toolkit.
