These fossil fuels, such as coal, oil, and natural gas, are extracted from large reserves buried underground. Nuclear energy, on the other hand, is derived from splitting atoms, known as nuclear fission, which releases energy from the nucleus of an atom. This process involves mining uranium and plutonium reserves found underground.
Nuclear energy and fossil fuels are both utilised to meet global energy demands, with fossil fuels currently providing the majority of the world's energy. However, fossil fuels are non-renewable resources, as they take millions of years to form, and viable reserves are being depleted much faster than new ones are created. Nuclear energy is also considered non-renewable, and care must be taken to ensure these underground reserves are not depleted.
The extraction and use of both energy sources have drawn criticism due to their environmental and health impacts. Fossil fuels, when burned, release large amounts of carbon dioxide and other pollutants into the atmosphere, contributing to global warming and air pollution. The use of fossil fuels has been linked to various health issues, including acute respiratory illness, aggravated asthma, chronic bronchitis, heart disease, and decreased lung function.
In contrast, nuclear energy production is known for its large-scale disasters, such as Chernobyl and Fukushima, which have had adverse health and environmental consequences. However, the safety and health concerns associated with nuclear power are considered less significant compared to the daily toll of fossil fuel usage. Nuclear energy is termed clean energy because it produces significantly lower amounts of pollutants and carbon dioxide during electricity generation.
While both energy sources are mined from underground, the critical distinction lies in their environmental impact and renewability. The transition away from fossil fuels towards nuclear energy or renewable alternatives is essential to mitigate climate change and improve human health on a global scale.
