A fossil fuel [a] is a carbon compound - or hydrocarbon -containing material such as coal, oil, and natural gas, [2] formed naturally in the Earth's crust from the remains of prehistoric organisms (animals, plants and planktons ), a process that occurs within geological formations. Reservoirs of such compound mixtures can be extracted and ...
Petrochemical. Petrochemicals (sometimes abbreviated as petchems [1]) are the chemical products obtained from petroleum by refining. Some chemical compounds made from petroleum are also obtained from other fossil fuels, such as coal or natural gas, or renewable sources such as maize, palm fruit or sugar cane .
Hydrogen gas is produced by several industrial methods. Nearly all of the world's current supply of hydrogen is created from fossil fuels. [1] [2] : 1 Most hydrogen is gray hydrogen made through steam methane reforming. In this process, hydrogen is produced from a chemical reaction between steam and methane, the main component of natural gas.
Approximately 72% of world oil production came from the top ten countries, and an overlapping 35% came from the twelve current OPEC members. Members of OPEC+, which includes current OPEC members produce about 60% of the world's petroleum. In addition to being top 5 in oil production, the United States and Russia are also top 5 in oil exports ...
Cement production (burning of fossil fuels) (4%) is estimated at 1.42 GtCO 2; Land-use change (LUC) is the imbalance of deforestation and reforestation. Estimations are very uncertain at 4.5 GtCO 2. Wildfires alone cause annual emissions of about 7 GtCO 2 [98] [99] Non-energy use of fuels, carbon losses in coke ovens, and flaring in crude oil ...

The three most quoted oil products are North America 's West Texas Intermediate crude (WTI), North Sea Brent Crude, and the UAE Dubai Crude, and their pricing is used as a barometer for the entire petroleum industry, although, in total, there are 46 key oil exporting countries. Brent Crude is typically priced at about $2 over the WTI Spot price ...
Biomass (in the context of energy generation) is matter from recently living (but now dead) organisms which is used for bioenergy production. There are variations in how such biomass for energy is defined, e.g. only from plants, [8] or from plants and algae, [9] or from plants and animals. [10] The vast majority of biomass used for bioenergy ...
