The total expenditure of energy in the world each year is about 3 × 10 17 kJ. Today, more than 80% of this energy is provided by the combustion of fossil fuels: oil, coal, and natural gas (The sources of the energy consumed in the United States in 2009 are shown in Figure ) but as Table from the Wikipedia shows, energy usage is a complex issue.

Answer Explanation. All tutors are evaluated by Course Hero as an expert in their subject area. Liquefaction is the process of converting solid coal into liquid fuels. The main difference between naturally occurring petroleum fuels and coal is the deficiency of hydrogen in the latter: coal contains only about half the amount found in petroleum.

Then, the gas is turned into a liquid that is used as fuel. This is done most often through the FischerTropsch process, which involves chemically refining the syngas to eliminate impurities, including sulfur and nitrogen, and converting it into either gasoline or diesel. This fuel is said to be cleaner than gasoline because it is sulfurfree.
