Natural gas is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane in addition to various smaller amounts of other higher alkanes. Usually low levels of trace gases like carbon dioxide, nitrogen, hydrogen sulfide, and helium are also present. Natural gas is colorless and odorless, so odorizers such as mercaptan, which smells like sulfur or rotten eggs, are commonly added to natural gas supplies for safety so that leaks can be readily detected.
A fossil fuel is a hydrocarbon-containing material formed naturally in the Earth's crust from the remains of dead plants and animals that is extracted and burned as a fuel. The main fossil fuels are coal, crude oil and natural gas. Fossil fuels may be burned to provide heat for use directly, to power engines, or to generate electricity. Some fossil fuels are refined into derivatives such as kerosene, gasoline and propane before burning. The origin of fossil fuels is the anaerobic decomposition of buried dead organisms, containing organic molecules created by photosynthesis. The conversion from these materials to high-carbon fossil fuels typically require a geological process of millions of years.
An energy crisis or energy shortage is any significant bottleneck in the supply of energy resources to an economy. In literature, it often refers to one of the energy sources used at a certain time and place, in particular, those that supply national electricity grids or those used as fuel in industrial development and population growth have led to a surge in the global demand for energy in recent years. In the 2000s, this new demand – together with Middle East tension, the falling value of the US dollar, dwindling oil reserves, concerns over peak oil, and oil price speculation – triggered the 2000s energy crisis, which saw the price of oil reach an all-time high of $147.30 per barrel ($926/m3) in 2008.
The 1979 oil crisis, also known as the 1979 Oil Shock or Second Oil Crisis, was an energy crisis caused by a drop in oil production in the wake of the Iranian Revolution. Although the global oil supply only decreased by approximately four percent, the oil markets' reaction raised the price of crude oil drastically over the next 12 months, more than doubling it to $39.50 per barrel ($248/m3). The sudden increase in price was connected with fuel shortages and long lines at gas stations similar to the 1973 oil crisis.
A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal or natural gas, to produce electricity. Fossil fuel power stations have machinery to convert the heat energy of combustion into mechanical energy, which then operates an electrical generator. The prime mover may be a steam turbine, a gas turbine or, in small plants, a reciprocating gas engine. All plants use the energy extracted from the expansion of a hot gas, either steam or combustion gases. Although different energy conversion methods exist, all thermal power station conversion methods have their efficiency limited by the Carnot efficiency and therefore produce waste heat.
The politics of climate change results from different perspectives on how to respond to climate change. Global warming is driven largely by the emissions of greenhouse gases due to human economic activity, especially the burning of fossil fuels, certain industries like cement and steel production, and land use for agriculture and forestry. Since the Industrial Revolution, fossil fuels have provided the main source of energy for economic and technological development. The centrality of fossil fuels and other carbon-intensive industries has resulted in much resistance to climate friendly policy, despite widespread scientific consensus that such policy is necessary.
The energy industry is the totality of all of the industries involved in the production and sale of energy, including fuel extraction, manufacturing, refining and distribution. Modern society consumes large amounts of fuel, and the energy industry is a crucial part of the infrastructure and maintenance of society in almost all countries.
Carbon capture and storage (CCS) or carbon capture and sequestration is the process of capturing carbon dioxide (CO2) before it enters the atmosphere, transporting it, and storing it (carbon sequestration) for centuries or millennia. Usually the CO2 is captured from large point sources, such as a chemical plant or biomass power plant, and then stored in an underground geological formation. The aim is to prevent the release of CO2 from heavy industry with the intent of mitigating the effects of climate change. CO2 has been injected into geological formations for several decades for enhanced oil recovery and after separation from natural gas, but this has been criticised for producing more emissions when the gas or oil is burned.
Renewable heat is an application of renewable energy referring to the generation of heat from renewable sources; for example, feeding radiators with water warmed by focused solar radiation rather than by a fossil fuel boiler. Renewable heat technologies include renewable biofuels, solar heating, geothermal heating, heat pumps and heat exchangers. Insulation is almost always an important factor in how renewable heating is implemented.
Energy descent is a process whereby a society either voluntarily or involuntarily reduces its total energy consumption.
The Carbon War: Global Warming and the End of the Oil Era is a 1999 book by former oil geologist Jeremy Leggett about global warming.
Crude (2007) is a 90-minute-long feature documentary made by Australian filmmaker Dr Richard Smith attempting to explain the links between formation, extraction and refining as well the link between geology and economy. The film features interviews with oil industry professionals and geologists about the future of oil production and exploration. The interviewed include Dr. Jeremy Leggett, a geologist formerly working with oil exploration for BP and Shell; Dr. Colin Campbell, a retired British petroleum geologist who predicted that oil production would peak by 2007; Lord Ronald Oxburgh, former chairman of Shell; Professor Wallace S. Broecker at Columbia University; and journalist Sonia Shah.
Jeremy Leggett is a British social entrepreneur and writer. He founded and was a board director of Solarcentury from 1997 to 2020, an international solar solutions company, and founded and was chair of SolarAid, a charity funded with 5% of Solarcentury's annual profits that helps solar-lighting entrepreneurs get started in Africa (2006–2020). SolarAid owns a retail brand SunnyMoney that was for a time Africa's top-seller of solar lighting, having sold well over a million solar lights, all profits recycled to the cause of eradicating the kerosene lantern from Africa.

"A Green New Deal" was a report released in the United Kingdom on 21 July 2008 by the Green New Deal Group and published by the New Economics Foundation, which outlines a series of policy proposals to tackle global warming, the current financial crisis, and peak oil. The report calls for the re-regulation of finance and taxation, and major government investment in renewable energy sources. Its full title is: A Green New Deal: Joined-up policies to solve the triple crunch of the credit crisis, climate change and high oil prices.
The environmental impact of the energy industry is significant, as energy and natural resource consumption are closely related. Producing, transporting, or consuming energy all have an environmental impact. Energy has been harnessed by human beings for millennia. Initially it was with the use of fire for light, heat, cooking and for safety, and its use can be traced back at least 1.9 million years. In recent years there has been a trend towards the increased commercialization of various renewable energy sources. Scientific consensus on some of the main human activities that contribute to global warming are considered to be increasing concentrations of greenhouse gases, causing a warming effect, global changes to land surface, such as deforestation, for a warming effect, increasing concentrations of aerosols, mainly for a cooling effect.
The climate change policy of the United States has major impacts on global climate change and on global climate change mitigation. This is because the United States is the second largest emitter of greenhouse gasses in the world after China, and is among the countries with the highest greenhouse gas emissions per person in the world. In total the United States has emitted over 400 billion metric tons of greenhouse gasses, more than any country in the world.
Individual action on climate change can include personal choices in many areas, such as diet, travel, household energy use, consumption of goods and services, and family size. Individuals can also engage in local and political advocacy around issues of climate change. As of 2020, emissions budgets are uncertain but estimates of the annual average carbon footprint per person required to meet the target of limiting global warming to 2 degrees by 2100 are all below the world average of about 5 tonnes CO2-equivalent. And to meet 1.5 degrees 2.3 tonnes annual average is required by 2030. According to 66% of respondents to an EU climate survey, climate change will still be a severe concern by 2050.
Carbon Tracker is a London-based not-for-profit think tank researching the impact of climate change on financial markets.
The 2021–2022 global energy crisis began in the aftermath of the COVID-19 pandemic in 2021, with much of the globe facing shortages and increased prices in oil, gas and electricity markets. The crisis was caused by a variety of economic factors, labor shortages, disputes, climate change, and was later compounded by the 2022 Russian invasion of Ukraine.
