Nuclear energy is widely regarded as a cleaner and safer alternative to fossil fuels. Nuclear power stations use a minuscule amount of fuel to generate the same amount of electricity as coal or gas power stations, making them more reliable and less polluting. Nuclear energy produces nearly zero carbon dioxide or other greenhouse gas emissions, and avoids the air pollutants associated with burning fossil fuels. While nuclear energy has been the subject of controversy due to accidents and radioactive waste, it has resulted in significantly fewer deaths than fossil fuels. As countries strive for net-zero carbon emissions, nuclear power is increasingly recognised as a pivotal solution to transition away from fossil fuels.

Nuclear energy is a clean energy source with minimal carbon emissions
Nuclear energy is widely recognised as a clean energy source with minimal carbon emissions. It has been a part of the global energy mix since the early 1950s, and today, it plays a pivotal role in providing clean, low-carbon electricity. Nuclear power stations generate electricity through nuclear fission, a process that splits atoms. This advanced scientific process produces nearly zero carbon dioxide and other greenhouse gas emissions, making it significantly cleaner than burning fossil fuels.
Nuclear energy's low-carbon credentials are particularly notable when compared to fossil fuels. Coal, oil, and gas, which dominate the global electricity mix, emit substantial greenhouse gases and are responsible for air pollution, contributing to climate change and adverse health effects. In contrast, nuclear power offers a much cleaner alternative, with up to 99.9% fewer deaths associated with its use compared to brown coal and 99.8% fewer than coal. This makes nuclear energy a safer option from a public health perspective.
The abundance of uranium, a common nuclear fuel, also contributes to the minimal carbon emissions of nuclear energy. Uranium is available from diverse producer countries and is incredibly energy-dense, requiring comparatively low volumes to produce electricity. This energy density means that nuclear power plants can operate for extended periods without refuelling, further reducing their carbon footprint. Additionally, nuclear power plants have a long operational lifespan, with some certified for up to 80 years, ensuring a consistent supply of low-carbon electricity.
While nuclear energy production results in radioactive waste, this waste can be managed and recycled. Approximately 90% of nuclear waste can be recycled, and the fuel used in reactors can be treated and reused. Although concerns about the indefinite disposal of spent fuel remain, the environmental impact of nuclear waste is considered a more manageable problem than climate change. Therefore, nuclear energy's ability to produce clean energy with minimal carbon emissions makes it an attractive option in the transition away from fossil fuels.
Nuclear energy's clean nature is further emphasised when compared to other renewable energy sources. While wind and solar power are expected to lead the push to replace fossil fuels, nuclear energy provides a more reliable and dispatchable power source. It offers large amounts of stable and resilient electricity, backing up variable renewables when sunshine or wind are lacking. This reliability, combined with its low-carbon attributes, positions nuclear energy as a crucial pillar in the transition to a sustainable, low-carbon energy future.

Nuclear power is safer, causing 99.9% fewer deaths than fossil fuels
Nuclear power is significantly safer than fossil fuels, causing 99.9% fewer deaths than brown coal, 99.8% fewer than coal, 99.7% fewer than oil, and 97.6% fewer than gas. Fossil fuels act as "invisible killers", responsible for one in every five deaths worldwide. In 2018 alone, 8.7 million people lost their lives due to fossil fuels. In contrast, since the inception of nuclear power, only three accidents have caused public concern: the Three Mile Island incident in 1979, the Chernobyl disaster in 1986, and the Fukushima disaster in 2011. Of these, only Chernobyl directly led to any fatalities.
The health risks posed by fossil fuels are not limited to accidents but also include air pollution, which contributes to a significant number of premature deaths. For instance, in a town of 150,000 people in the European Union, or 'Euroville', if the town's electricity was completely generated by coal, at least 25 people would be expected to die prematurely each year due to air pollution. This highlights the stark contrast in safety profiles between nuclear power and fossil fuels.
Nuclear power stations also work similarly to coal- and gas-fired power stations, but the science behind nuclear power production is much more advanced. Nuclear power plants use a minuscule amount of fuel to generate the same amount of electricity as coal or gas power stations. For example, 1 kg of uranium contains the same energy as 2.7 million kg of coal. This makes nuclear fuel a highly efficient and reliable source of energy.
Furthermore, nuclear power is considered a clean energy technology as it produces nearly zero carbon dioxide and other greenhouse gas emissions. It avoids the air pollutants associated with burning fossil fuels, which contribute to climate change and have detrimental effects on human health. Nuclear power also has a lower carbon footprint, uses fewer materials, and requires less land compared to fossil fuels and some renewable energy sources like solar power.
While nuclear power has its challenges, such as the long-term disposal of nuclear waste, it is still considered a safer and more environmentally friendly option than fossil fuels. Nuclear waste can be recycled, and the risk it poses is considered easier to manage than the impact of climate change caused by fossil fuels. As a result, nuclear power is increasingly recognised as a vital component in the transition to cleaner and safer energy sources.

Nuclear plants are competitive with fossil fuels in electricity generation
Nuclear power plants are competitive with fossil fuels in electricity generation. Nuclear power plants are expensive to build but relatively cheap to run. Nuclear power plants use a minuscule amount of fuel to generate the same amount of electricity as a coal or gas power station. For example, 1 kg of uranium contains the same amount of energy as 2.7 million kg of coal. This makes nuclear fuel a reliable source of energy for decades to come.
Nuclear energy is also considered a clean energy technology as it produces nearly zero carbon dioxide or other greenhouse gas emissions. It avoids producing air pollutants that are often associated with burning fossil fuels for energy. Nuclear energy is pivotal in our efforts to reach net-zero by 2050. According to a 2022 report from the International Energy Agency (IEA), "Nuclear energy can help make the energy sector's journey away from unabated fossil fuels faster and more secure."
Nuclear power plants are also safer than fossil fuels. In nearly 70 years since the beginning of nuclear power, only three accidents have raised public alarm: the 1979 Three Mile Island accident, the 1986 Chernobyl disaster, and the 2011 Fukushima nuclear disaster. Of these, only Chernobyl directly caused any deaths. In contrast, fossil fuels are responsible for 1 in 5 deaths worldwide. In 2018 alone, fossil fuels killed 8.7 million people globally.
Nuclear electricity production costs are also less sensitive to changes in fuel prices than electricity generated from oil and gas. Uranium is available from a range of diverse producer countries and is incredibly energy-dense, meaning comparatively low volumes are required. Enough uranium fuel for several years of electricity production can be easily stored on the site of nuclear power plants.
