Detailed explanation-1: -In the US, coal and natural gas are the largest contributors to carbon pollution (constituting a third of all domestic carbon emissions).

Detailed explanation-2: -Coal is a fossil fuel, and is the dirtiest of them all, responsible for over 0.3C of the 1C increase in global average temperatures. This makes it the single largest source of global temperature rise. Oil releases a huge amount of carbon when burned-approximately a third of the world’s total carbon emissions.

Detailed explanation-3: -Coal is the most economical fuel and is used for base-load power generation. Crude oil can be procured with greater flexibility and is used for middle-to-peak load power generation.

Detailed explanation-4: -Coal is both the largest source of electricity generation and the largest single source of CO2 emissions, creating a unique challenge in transitioning to low-carbon energy systems.

Detailed explanation-5: -The estimated CO 2 emission from the world’s electrical power industry is 10 billion tonnes yearly. This results in an increase in the Earth’s levels of atmospheric carbon dioxide, which enhances the greenhouse effect and contributes to global warming.
