Despite recent technical and political efforts, we are still heavily dependent on them. Advantages of fossil fuels ■■ Fossil fuels are highly stable in nature compared to other fuels. ■■ Coal, oil and gas are still available in large quantities. ■■ Converting them to heat energy is very efficient. ■■ Equipment for the production of energy from fossil fuels is fully developed. ■■ Transport of current liquid or gaseous fuels is relatively simple, and distribution networks are well-established. Disadvantages of fossil fuels ■■ Fossil fuels are the largest source of greenhouse gases such as carbon dioxide and methane, the major contributors to global warming. They can also damage the ozone layer. ■■ Fossil fuels emit harmful gases such as carbon monoxide and sulphur dioxide, which produce acid rain. ■■ Renewable energy sources are getting cheaper and cheaper. ■■ Extraction of fossil fuels threatens the geological balance in many areas (e.g. because of spills or the damage done by fracking). ■■ Although fuels such as oil and natural gas are still available, their exploitation has resulted in their depletion. ■■ They are non-renewable in nature.
