What are the pros and cons of non-renewable energy?
Pros: – Low cost Cons: – Not sustainable – Produces carbon dioxide. (CO2), which is an important greenhouse gas. – The methods of mining coal can be very destructive. – Very large quantities of coal ash have to be disposed of and a lot of smoke is produced. – Some coal contains significant amounts of sulfur. After burning, this changes to sulfur dioxide and eventually sulfuric acid, if it is not removed at some stage. Burned sulfur is one of the main causes of acid rain. – The world’s natural gas reserves are limited. – The world’s oil reserves are limited. – Oil spills, especially at sea, cause severe pollution. – Some oils contain high levels of sulfur.
