What do coal, oil, and natural gas have in common?

Answer 1

All three are fossil fuels that are non-renewable resources and all three are contributing to global climate change. They are used in different applications.

Natural gas is used for power generation and is actually replacing coal in North America. It is also used for making cement, heating homes, and plastic products. Of the three fossil fuels, coal is used almost exclusively for electricity generation and emits the most CO2. Oil is used almost exclusively for fuel in the transportation sector (cars, buses, trains, planes, etc.).
