Detailed explanation-1: -Remains of plants and animals which were buried under the earth for millions of years got converted by the heat and pressure into fossil fuels. Fossil fuel such as coal, petroleum and natural gas are the main sources of conventional energy. The reserves of these minerals are limited.
Detailed explanation-2: -A. Fossil fuels are coal, petroleum and natural gas.
Detailed explanation-3: -For this reason fossil fuels are incredibly “energy dense“, meaning a little bit of a fossil fuel can produce a whole lot of energy. This energy dense quality is what led to Europe’s adoption of coal over wood as a fuel source, and this sudden increase in available energy eventually led to the industrial revolution.
Detailed explanation-4: -Coal and petroleum are fossil fuels that require millions of years to be formed. They are natural resources and are limited in supply. Once exhausted, they cannot be formed again in a short time. Therefore, fossil fuels like coal and petroleum should be used judiciously.
