The origin of fossil fuels is the anaerobic decomposition of buried dead organisms. The conversion from these organic materials to high-carbon fossil fuels typically requires a geological process of millions of years. [4] Due to the length of time it takes nature to form them, fossil fuels are considered non-renewable resources.
These latter sources are properly known as mineral fuels. Fossil fuels contain high percentages of carbon and include coal, petroleum, and natural gas. [12] They range from volatile materials with low carbon:hydrogen ratios like methane, to liquid petroleum to nonvolatile materials composed of almost pure carbon, like anthracite coal.
Carbon-based fuel is any fuel principally from the oxidation or burning of carbon.Carbon-based fuels are of two main kinds, biofuels and fossil fuels.Whereas biofuels are derived from recent-growth organic matter [1] and are typically harvested, as with logging of forests and cutting of corn, fossil fuels are of prehistoric origin [2] and are extracted from the ground, the principal fossil ...
Co-processing is the use of waste as raw material, or as a source of energy, or both to replace natural mineral resources (material recycling) and fossil fuels such as coal, petroleum and gas (energy recovery) in industrial processes, mainly in energy intensive industries (EII) such as cement, lime, steel, glass, and power generation.
The increased dependence during the 20th century on carbon-emitting energy sources, such as fossil fuels, and carbon-emitting renewables, such as biomass, means that the energy industry has frequently contributed to pollution and environmental impacts on the economy.

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]
Deaths caused by use of fossil fuels such as oil (areas of rectangles in chart) greatly exceed those resulting from production of renewable energy (rectangles barely visible in chart). [45] Some harmful impacts of petroleum can be limited to the geographic locations where it is produced, consumed, and/or disposed.
