Which fossil fuel produces the most energy when burned?

Answer 1

Coal releases more carbon dioxide than oil.

Oil releases more than natural gas.

A:We burn more coal (a little over four billion tons per year) than any other. Oil (over 3 billion tons) comes in a close second. A:Coal, then oil, then natural gas (methane).

Answer 2

Coal is almost pure carbon. So the oxidation of it should emit the largest quantity of carbon dioxide, pound for pound.

There are other, more potent greenhouse gases, such as nitrous oxide and methane. However, these themselves can act as fuel. Burning methane is much better than burning fossil fuel, even though both release CO2, simply because CH4 is a more efficient insulating gas.

Answer 3

The fossil fuel that requires the most energy before it can be used as a fuel is the natural gas. Coal and oil are fossils that will not require so much energy to used as fuel.

Answer 4

those with the most carbons

Answer 5

Diesel.

Answer 6

petroleum!

Answer 7

coal
