How can coal be conserved?

More efficient coal technologies can increase this to 40–50% efficient range, but these come at a big cost. For example, older coal-fired technologies are only about 30–35% efficient, meaning that 65% of the energy in the coal is wasted as heat and pollutants.

Since coal emits a significant amount of CO2, countries like China and India are closely examining more efficient technologies that would reduce the amount of coal needed to produce the same amount of power as they currently do. Currently, Canada, the United States, and other European countries have committed to phase out the use of coal for power generation.

Another significant factor is the current low cost of natural gas in North America, which is forcing many utilities to switch from coal to this fuel source.

Coal can be conserved through various methods, including implementing energy-efficient technologies, promoting renewable energy sources, increasing recycling and reusing of materials, and advocating for policies and regulations that encourage sustainable practices in coal mining and consumption. Additionally, investing in research and development for cleaner coal technologies, such as carbon capture and storage, can also help reduce coal consumption and minimize its environmental impact.
