Infrastructure for using fossil fuels already exists

, making them a convenient and readily available source of energy. This includes pipelines, refineries, storage facilities, and power plants that have been in place for decades. This existing infrastructure can be expensive to replace or upgrade, making it challenging to shift to alternative sources of energy. Additionally, fossil fuels are still cheaper and more widely used compared to renewable energy sources, further incentivizing their continued use. This dependence on fossil fuels has also led to a well-established industry that employs millions of people globally, making the transition to cleaner energy sources a complex and difficult task.
