No smoking zone is a area where you are restricted to smoke

a natural fuel such as coal or oil, that was formed millions of years ago from dead animals or plants in the ground

A fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis. Such organisms and their resulting fossil fuels typically have an age of millions of years, and sometimes more than 650 million years.

The four types of fossil fuels are petroleum, coal, natural gas and Orimulsion (capitalized because it is a proprietary, or trade, name). They have a number of important physical, chemical and other properties in common, but perhaps the most critical fact about fossil fuels is that they are not renewable. Once they are used up, that's it; many more millions of years have to pass before even small amounts can be made again, assuming the same processes will ever even occur on the same scale.

Also, fossil fuels in their natural form store tremendous amounts of carbon, keeping it from leaking into the atmosphere. Burning them, however, "unlocks" the carbon and returns it to the atmosphere at rates far faster than even would occur without human industry in the mix. The combustion of fossil fuels plays an established role in the anthropogenic global warming (AGW) that has been underway for decades and is already damaging ecosystems around the planet.

Petroleum

In the year 2017, petroleum – in other words, crude oil and substances known as "natural gas plant liquids" – accounted for 28 percent of American primary energy production. The U.S., while perhaps regarded by many of its own citizens as mainly an oil-importing nation, is actually among the top oil producers in the world. Thanks to the reputation of some Middle Eastern nations as effectively controlling most of the world's oil production, and to undeniably sky-high U.S. oil consumption, this fact is often obscured.

Because the petroleum product gasoline is relatively portable compared to coal, most petroleum production and use is in the transportation sector. In fact, 71 percent of energy used in the U.S. transportation sector is supplied by petroleum, which plays virtually no role in the generation of electrical power.

In 2018, over half of U.S. oil produced came from two states alone: Texas and North Dakota.

Coal

Coal supplied about 18 percent of U.S. energy needs in 2017. The total amount produced was 775 million short tons, and this coal came from a total of 24 U.S. states. Wyoming by far contributed the greatest share at 41 percent, with West Virginia a distant second at 12 percent. A decade earlier, coal's contribution to American energy production was just slightly lower than that of natural gas, 23 percent to 22 percent.

The solid nature of coal makes it ideally suited for keeping in one place for electricity production, and this has been its overwhelming role in the energy game over the years. Coal production in 2017 was about the same as it was in 1979, but the U.S. population also grew by about 100 million people in that time. As coal production for electricity has dropped in favor of other sources, coal's overall role in the fuel economy has diminished.

Coal is about 70 to 90 percent carbon by mass. Four subtypes exist, all with different properties in terms the amount of energy liberated from the breaking of carbon bonds when the coal is burned.

Natural Gas

Natural gas accounted for 32 percent of the American energy share in 2017, and total production was the second-highest ever. In fact, beginning in about 2005, natural gas became more accessible in much of the United States thanks to the increased use of horizontal drilling and the well-stimulation technique known as hydraulic fracturing ("fracking").

The rise of fracking in the early 21st century – a practice controversial because it consumes vast amounts of water, invariably disturbs the local environment and may even have the potential to cause small earthquakes – is tied to the decision on the part of a Texas oil company to try to extract natural gas from a kind of rock called shale, abundant in that part of the country. The commercial success of the technique led to its adoption by other companies in other areas where shale is found.

Natural gas is considered clean-burning compared to other fossil fuels; it is getting it out of the ground that is the most problematic aspect of its production.

Orimulsion: A Flash in the Energy Pan

Off the coast of Venezuela sits the Orinoco Oil Belt, which is home to a unique repository of an especially heavy type of oil. Starting in 1991, this was made into a proprietary product called Orimulsion, which consisted of 70 percent heavy oil and 30 percent water. It was hoped that this could cut significantly into the fossil-fuel market share, but production was stopped in 2006.
