What is one major disadvantage of fossil-fired generation?

Fossil-fired generation refers to the production of electricity using fossil fuels such as coal, natural gas, or oil. One major disadvantage associated with this method of power generation is the emission of pollutants. Burning fossil fuels releases a variety of harmful substances into the atmosphere, including carbon dioxide (a greenhouse gas), sulfur dioxide, nitrogen oxides, and particulate matter. These emissions contribute to air pollution, climate change, and health problems for the population. The environmental impact of these emissions is significant, leading to stricter regulations and a push towards cleaner energy sources.

In contrast to this disadvantage, other options either highlight aspects that are not truly negative or focus on benefits associated with fossil fuels, such as high production capacity, the utilization of renewable resources, or promoting energy independence, which do not capture the main environmental risks posed by fossil-fired generation.
