The world is currently facing a complex and urgent energy crisis. The demand for energy is growing, while conventional fossil fuels like coal, oil, and natural gas are becoming scarcer. This situation not only exacerbates environmental issues such as global warming, air and water pollution, and land degradation, but also hampers sustainable development, which aims to integrate environmental protection, economic growth, and social welfare in a balanced manner.

The attainment of the Sustainable Development Goals outlined in the 2030 Agenda relies heavily on the provision of a sustainable energy supply. Energy production and consumption are fundamental to economic development and social progress. Thus, a crucial step towards achieving these goals is transitioning the global energy mix to incorporate a greater proportion of renewable energy sources.

But what exactly does "sustainable energy supply" mean? It refers to a combination of energy sources that are affordable, reliable, and clean. Such sources not only contribute to reducing greenhouse gas emissions and environmental pollution, but also ensure a secure and stable energy supply for future generations. Renewable energy sources, including solar, wind, hydro, geothermal, and biomass energy, fit within this definition. However, their effectiveness varies depending on factors such as location, resource availability, and technology. Additionally, some renewable sources, like solar and wind power, are intermittent due to weather conditions.

To guarantee a constant power supply to the grid, regardless of weather conditions, we need to consider baseload energy sources. These sources play a crucial role in providing a reliable flow of electricity. Unfortunately, the current baseload generation heavily relies on non-renewable sources like coal and natural gas. While these sources do provide a consistent energy supply, they come with negative environmental impacts and contribute to climate change.

As emphasized in the 2030 Agenda, providing a clean, sustainable, and reliable energy supply is essential for economic development and social progress. Let's explore further to understand how we can address this challenge and the potential role of different energy sources, including nuclear energy, in shaping our future energy mix.
