The use of fossil fuels (coal, oil and natural gas) is a problem because the burning of these fuels in industry, transport and the generation of electricity releases carbon dioxide (CO2).This is causing global warming and climate change.: The combustion (burning) of fossil fuels releases poisonous gases into the atmosphere. Oil/Petrol, for instance, is a Hydrocarbon (a mix of Carbon and Hydrogen atoms) and when burnt with Oxygen creates Carbon Monoxide and Carbon Dioxide.
Fossil fuels power our lifestyles and drive the nationâs economy. Oil, natural gas and coal provide lights, air conditioning and heat for homes; fuel for transportation; and energy that powers all types of production.The nationâs economy and much of its infrastructure revolve around fossil fuels; consequently, these energy sources have important economic impacts. chief drawback to fossil fuels is the amount of pollution they create. Pollution is a classic example in economics textbooks of a negative externality. Pollution affects the health and quality of life of all people and leads to costly regulations designed to limit pollution.
