petroleum and coal....

Answer 2

Answer:

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.Fossil fuels contain high percentages of carbon and include petroleum, coal, and natural gas. Commonly used derivatives of fossil fuels include kerosene and propane. Fossil fuels range from volatile materials with low carbon-to-hydrogen ratios (like methane), to liquids (like petroleum), to nonvolatile materials composed of almost pure carbon, like anthracite coal. Methane can be found in hydrocarbon fields either alone, associated with oil, or in the form of methane clathrates.

The theory that fossil fuels formed from the fossilized remains of dead plants by exposure to heat and pressure in the Earth's crust over millions of years was first introduced by Andreas Libavius "in his 1597 Alchemia [Alchymia]" and later by Mikhail Lomonosov "as early as 1757 and certainly by 1763".The first use of the term "fossil fuel" occurs in the work of the German chemist Caspar Neumann, in English translation in 1759. The Oxford English Dictionary notes that in the phrase "fossil fuel" the adjective "fossil" means "[o]btained by digging; found buried in the earth", which dates to at least 1652- before the English noun "fossil" came to refer primarily to long-dead organisms in the early 18th century.

As of 2017 the world's primary energy sources consisted of petroleum (34%), coal (28%), natural gas (23%), amounting to an 85% share for fossil fuels in primary energy-consumption in the world. Non-fossil sources as of 2006 included nuclear (8.5%), hydroelectric (6.3%), and others ( geothermal, solar, tidal, wind, wood, waste) amounting to 0.9%. World energy-consumption was growing[when?] at about 2.3% per year. As of 2015 about 18% of worldwide consumption came from renewable sources.
