WHAT IS Fossil fuel
Fossil fuels are hydrocarbons, primarily coal, fuel oil or natural gas, formed from the remains of dead plants and animals.
In common dialogue, the term fossil fuel also includes hydrocarbon-containing natural resources that are not derived from animal or plant sources.
These are sometimes known instead as mineral fuels.
The utilization of fossil fuels has enabled large-scale industrial development and largely supplanted water-driven mills, as well as the combustion of wood or peat for heat.
Fossil fuel is a general term for buried combustible geologic deposits of organic materials, formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years.
The burning of fossil fuels by humans is the largest source of emissions of carbon dioxide, which is one of the greenhouse gases that allows radiative forcing and contributes to global warming.
A small portion of hydrocarbon-based fuels are biofuels derived from atmospheric carbon dioxide, and thus do not increase the net amount of carbon dioxide in the atmosphere.
How much does fossil fuel energy benefit society?
The benefits to society of fossil fuel energy far outweigh the social costs of carbon by a magnitude of 50 to 500 times, according to a study released by the American Coalition for Clean Coal Electricity (ACCCE).
According to the study, “The Social Costs Of Carbon? No, The Social Benefits Of Carbon,” over the past 250 years global life expectancy has more than doubled and incomes have increased 11-fold in large part due to increased energy production and delivery, most of which has been fossil-based. And although a United States government Federal Interagency Working Group (IWG) estimated the social cost of carbon to be $36/ton; the actual societal benefits of carbon - as a by-product of energy production - is 50 to 500 times greater than the perceived cost.
Moving away from fossil fuels will be costly and slow … but essential, UBS says
Last year saw global energy demand increase at its fastest rate since 2010, according to a research note from analysts at UBS Monday.
The note said that although there was a "growing desire" to transition away from fossil fuels, "demand for most energy resources, including fossil fuels" would continue to rise. It added that while renewable fuel supplies were set to increase at a fast pace, diversification from non-renewable resources would be expensive and time consuming,"Despite growing aspirations to diversify away from fossil fuels, we think demand for most energy resources, including oil, coal, and natural gas, is likely to keep rising over the coming decade," the UBS analysts said in the research.
"We believe supplies of renewable energy will keep rising at an unprecedented pace over the next few decades. But diversification of our current energy resource base away from non-renewable energy resources such as oil, coal, and natural gas on a meaningful scale will be costly and time consuming. We expect the transition to occur only gradually."
However, the research team added that the development of renewable energy was "essential" and a "necessary step in securing our energy future."
The environmental benefits of renewable sources of energy were cited as the "key motivator" for the development of renewables in the near term.
The note said that diversification would be needed to "mitigate the risk of instability in energy availability and pricing." This would be especially pertinent in times of supply or demand shocks in the oil and gas markets, it added.
The renewable energy sector employed 11 million people in 2018, according to a recent report from the International Renewable Energy Association (IRENA). Most renewable energy jobs were in the solar photovoltaic industry, which employed 3.6 million people, according to IRENA.
