Fossil fuel phase-out is the gradual reduction of the use and production of fossil fuels to zero, to reduce deaths and illness from air pollution, limit climate change, and strengthen energy independence. It is part of the ongoing renewable energy transition, but is being hindered by fossil fuel subsidies.
Many countries are shutting down coal-fired power stations, [6] [7] [8] and fossil-fuelled electricity generation is thought to have peaked. [9] But electricity generation is not moving off coal fast enough to meet climate goals. [10] Many countries have set dates to stop selling petrol and diesel cars and trucks, but a timetable to stop burning fossil gas has not yet been agreed. [11]
Current efforts in fossil fuel phase-out involve replacing fossil fuels with sustainable energy sources in sectors such as transport and heating. Alternatives to fossil fuels include electrification, green hydrogen and biofuel. Phase-out policies include both demand-side and supply-side measures. [12] Whereas demand-side approaches seek to reduce fossil-fuel consumption, supply-side initiatives seek to constrain production to accelerate the pace of energy transition and reduction in emissions. It has been suggested that laws should be passed to make fossil fuel companies bury the same amount of carbon as they emit. [13] The International Energy Agency estimates that in order to achieve carbon neutrality by the middle of the century, global investments in renewable energy must triple by 2030, reaching over $4 trillion annually.

While crude oil and natural gas are also being phased out in chemical processes (e.g. production of new building blocks for plastics) as the circular economy and biobased economy (e.g. bioplastics) are being developed [16] to reduce plastic pollution, the fossil fuel phase out specifically aims to end the burning of fossil fuels and the consequent production of greenhouse gases. Therefore, attempts to reduce the use of oil and gas in the plastic industry do not form part of fossil fuel phase-out or reduction plans.
To meet the Paris Agreement target of keeping global warming to well below 2 °C (3.6 °F), coal use needs to halve from 2020 to 2030. [20] However, as of 2017 [update] , coal supplied over a quarter of the world's primary energy [21] and about 40% of the greenhouse gas emissions from fossil fuels. [22] Phasing out coal has short-term health and environmental benefits which exceed the costs, [23] and without it the 2 °C target in the Paris Agreement cannot be met; [24] but some countries still favour coal, [25] and there is much disagreement about how quickly it should be phased out. [26] [27]
As of 2018 [update] , 30 countries and many sub-national governments and businesses [28] had become members of the Powering Past Coal Alliance, each making a declaration to advance the transition away from unabated (abated means with carbon capture and storage (CCS), but almost all power plants are unabated as CCS is so expensive) coal power generation. [29] As of 2019 [update] , however, the countries which use the most coal have not joined, and some countries continue to build and finance new coal-fired power stations. A just transition from coal is supported by the European Bank for Reconstruction and Development. [30]
In 2019 the UN Secretary General said that countries should stop building new coal power plants from 2020 or face 'total disaster'. [31]
In 2020, although China built some plants, globally more coal power was retired than built: the UN Secretary General has said that OECD countries should stop generating electricity from coal by 2030 and the rest of the world by 2040. [32]
Crude oil is refined into fuel oil, diesel and petrol. The refined products are primarily for transportation by conventional cars, trucks, trains, planes and ships. Popular alternatives are human-powered transport, public transport, electric vehicles, and biofuels. [33]
Natural gas is widely used to generate electricity and has an emission intensity of about 500 g/kWh. Heating is also a major source of carbon dioxide emissions. Leaks are also a large source of atmospheric methane.
In some countries natural gas is being used as a temporary "bridge fuel" to replace coal, in turn to be replaced by renewable sources or a hydrogen economy. [34] However this "bridge fuel" may significantly extend the use of fossil fuel or strand assets, such as gas-fired power plants built in the 2020s, as the average plant life is 35 years. [35] Although natural gas assets are likely to be stranded later than oil and coal assets, perhaps not until 2050, some investors are concerned by reputational risk. [36]
Fossil gas phase-out has progressed in some regions, for example with increasing use of hydrogen by the European Network of Transmission System Operators for Gas (ENTSOG) [37] and changes to building regulations to reduce the use of gas heating. [38] [39]
Commonly cited reasons for phasing out fossil fuels are to:
Most of the millions [42] of premature deaths from air pollution are due to fossil fuels. [43] Pollution may be indoors e.g. from heating and cooking, or outdoors from vehicle exhaust. One estimate is that the proportion is 65% and the number 3.5 million each year. [44] According to Professor Sir Andy Haines at the London School of Hygiene and Tropical Medicine the health benefits of phasing out fossil fuels measured in money (estimated by economists using the value of life for each country) are substantially more than the cost of achieving the 2 °C goal of the Paris Agreement. [45]
Fossil-fuel phase-out is the largest part of limiting global warming as fossil fuels account for over 70% of greenhouse gas emissions. [46] In 2020, the International Energy Agency said that to meet the goals of the Paris Agreement, the phase-out of fossil fuels would need to "move four times faster". [47] To achieve the goal of limiting global warming to 1.5 °C above pre-industrial levels, the vast majority of fossil fuel reserves owned by countries and companies as of 2021 would have to remain in the ground. [48] [49]

The renewable energy transition can create jobs through the construction of new power plants and the manufacturing of the equipment that they need, as was seen in the case of Germany and the wind power industry. [50]
Countries which lack fossil fuel deposits, particularly coal but also petroleum and natural gas, often cite energy independence in their shift away from fossil fuels.
In Switzerland the decision to electrify virtually the entire railway network was taken in light of the two world wars (during which Switzerland was neutral) when coal imports became increasingly difficult. As Switzerland has ample hydropower resources, electric trains (as opposed to those driven by steam locomotives or diesel) could be run on domestic energy resources, reducing the need for coal imports. [51] [52]
The 1973 oil crisis also led to a shift in energy policy in many places to become (more) independent of fossil fuel imports. In France the government announced an ambitious plan to expand nuclear power which by the end of the 1980s had shifted France's electricity sector almost entirely away from coal gas and oil and towards nuclear power. [53] [54]
The trend towards encouraging cycling in the Netherlands [55] [56] and Denmark [57] [58] also coincided with the 1973 oil crisis and aimed in part at reducing the need for oil imports in the transportation sector.
Significant fossil fuel subsidies are present in many countries. [59] Fossil fuel subsidies in 2019 for consumption totalled US$320 billion [60] spread over many countries. [61] As of 2019 [update] governments subsidise fossil fuels by about $500 billion per year: however using an unconventional definition of subsidy which includes failing to price greenhouse gas emissions, the International Monetary Fund estimated that fossil fuel subsidies were $5.2 trillion in 2017, which was 6.4% of global GDP. [62] Some fossil fuel companies lobby governments. [63]
Phasing out fossil fuel subsidies is crucial to address the climate crisis. [64] It must however be done carefully to avoid protests [65] and making poor people poorer. [66] In most cases, however, low fossil fuel prices benefit wealthier households more than poorer households. So to help poor and vulnerable people, other measures than fossil fuel subsidies would be more targeted. [67] This could in turn increase public support for subsidy reform. [68]
Economic theory indicates that the optimal policy would be to remove coal mining and burning subsidies and replace them with optimal[ clarification needed ] taxes. Global studies indicate that even without introducing taxes, subsidy and trade barrier removal at a sectoral level would improve efficiency and reduce environmental damage. [69] Removal of these subsidies would substantially reduce greenhouse gas emissions and create jobs in renewable energy. [70] The IMF estimated in 2023 that removal of fossil fuel subsidies would limit global heating to the Paris goal of substantially less than 2 °C. [71]
The actual effects of removing fossil fuel subsidies would depend heavily on the type of subsidy removed and the availability and economics of other energy sources. [69] [ obsolete source ] There is also the issue of carbon leakage, where removal of a subsidy to an energy-intensive industry could lead to a shift in production to another country with less regulation, and thus to a net increase in global emissions.
In developed countries, energy costs are low and heavily subsidised, whereas in developing countries, the poor pay high costs for low-quality services. [72]
In 2009, studies have put forward a plan to power 100% of the world's energy with wind, hydroelectric, and solar power by the year 2030. [73] [74] It recommends transfer of energy subsidies from fossil fuel to renewable, and a price on carbon reflecting its cost for flood, cyclone, hurricane, drought, and related extreme weather expenses.
Excluding subsidies, the levelised cost of electricity from new large-scale solar power in India and China has been below existing coal-fired power stations since 2021. [75]
A study by Rice University Center for Energy Studies suggested the following steps for countries: [41]
Energy efficiency is complementary to the use of sustainable energy sources, when phasing-out fossil fuels.
Many countries and cities have introduced bans on the sales of new internal combustion engine (ICE) vehicles, requiring all new cars to be electric vehicles or otherwise powered by clean, non-emitting sources. [79] [80] Such bans include the United Kingdom by 2035 [81] and Norway by 2025. Many transit authorities are working to purchase only electric buses while also restricting use of ICE vehicles in the city center to limit air pollution. Many US states have a zero-emissions vehicle mandate, incrementally requiring a certain per cent of cars sold to be electric. The German term Verkehrswende ("traffic transition" analogous to Energiewende, energetic transition) calls for a shift from combustion powered road transport to bicycles, walking and rail transport and the replacement of remaining road vehicles with electric traction.
Biofuels, in the form of liquid fuels derived from plant materials, are entering the market. However, many of the biofuels that are currently being supplied have been criticised for their adverse impacts on the natural environment, food security, and land use. [82] [83]
The mitigation of peak oil is the attempt to delay the date and minimize the social and economic effects of peak oil by reducing the consumption of and reliance on petroleum.[ citation needed ] By reducing petroleum consumption, mitigation efforts seek to favorably change the shape of the Hubbert curve, which is the graph of real oil production over time predicted by Hubbert peak theory. The peak of this curve is known as peak oil, and by changing the shape of the curve, the timing of the peak in oil production is affected. An analysis by the author of the Hirsch report showed that while the shape of the oil production curve can be affected by mitigation efforts, mitigation efforts are also affected by the shape of Hubbert curve. [84]
For the most part, mitigation involves fuel conservation, and the use of alternative and renewable energy sources. The development of unconventional oil resources can extend the supply of petroleum, [85] but does not reduce consumption.
Historically, world oil consumption data show that mitigation efforts during the 1973 and 1979 oil shocks lowered oil consumption, while general recessions since the 1970s have had no effect on curbing the oil consumption until 2007.[ citation needed ] In the United States, oil consumption declines in reaction to high prices. [86] [87]
Key questions for mitigation are the viability of methods, the roles of government and private sector and how early these solutions are implemented. [88] [89] The responses to such questions and steps taken towards mitigation may determine whether or not the lifestyle of a society can be maintained, and may affect the population capacity of the planet.
The most effective method of mitigating peak oil is to use renewable or alternative energy sources in place of petroleum.
Because most oil is consumed for transportation [90] most mitigation discussions revolve around transportation issues.
Due to its high energy density and ease of handling, oil has a unique role as a transportation fuel. There are, however, a number of possible alternatives. Among the biofuels the use of bioethanol and biodiesel is already established to some extent in some countries.
The use of hydrogen fuel is another alternative under development in various countries, alongside, hydrogen vehicles [91] though hydrogen is actually an energy storage medium, not a primary energy source, and consequently the use of a non-petroleum source would be required to extract the hydrogen for use. Though hydrogen is currently outperformed in terms of cost and efficiency by battery powered vehicles [92] [ citation needed ], there are applications where it would come in useful. Short haul ferries and very cold climates are two examples. Hydrogen fuel cells are about a third as efficient as batteries and double the efficiency of petrol vehicles.
The Airbus A380 flew on alternative fuel for the first time on 1 February 2008.[ citation needed ] Boeing also plans to use alternative fuel on the 747. [93] Because some biofuels such as ethanol contains less energy, more "tankstops" might be necessary for such planes.
The US Air Force is currently in the process of certifying its entire fleet to run on a 50/50 blend of synthetic fuel derived from the Fischer–Tropsch process and JP-8 jet fuel. [94]
In 2015, Greenpeace and Climate Action Network Europe released a report highlighting the need for an active phase-out of coal-fired generation across Europe. Their analysis derived from a database of 280 coal plants and included emissions data from official EU registries. [98]
A 2016 report by Oil Change International, concludes that the carbon emissions embedded in the coal, oil, and gas in currently working mines and fields, assuming that these run to the end of their working lifetimes, will take the world to just beyond the 2 °C limit contained in the 2015 Paris Agreement and even further from the 1.5 °C goal. [99] [100] [101] The report observes that "one of the most powerful climate policy levers is also the simplest: stop digging for more fossil fuels". [101] : 5
In 2016, the Overseas Development Institute (ODI) and 11 other NGOs released a report on the impact of building new coal-fired power plants in countries where a significant proportion of the population lacks access to electricity. The report concludes that, on the whole, building coal-fired power plants does little to help the poor and may make them poorer. Moreover, wind and solar generation are beginning to challenge coal on cost. [102] [103] [104]
A 2018 study in Nature Energy, suggests that 10 countries in Europe could completely phase out coal-fired electricity generation with their current infrastructure, whilst the United States and Russia could phase out at least 30%. [105]
In 2020, the Fossil Fuel Cuts Database provided the first global account of supply-side initiatives to constrain fossil fuel production. [106] The latest update of the database recorded 1967 initiatives implemented between 1988 and October 2021 in 110 countries across seven major types of supply-side approaches (Divestment, n=1201; Blockades, n= 374; Litigation, n= 192; Moratoria and Bans, n= 146; Production subsidies removal, n=31; Carbon tax on fossil fuel production, n=16; Emissions Trading Schemes, n= 7).
The GeGaLo index of geopolitical gains and losses assesses how the geopolitical position of 156 countries may change if the world fully transitions to renewable energy resources. Former fossil fuel exporters are expected to lose power, while the positions of former fossil fuel importers and countries rich in renewable energy resources is expected to strengthen. [107]
Multiple decarbonisation plans that get to zero CO2 emissions have been presented.
A Guardian investigation showed in 2022, that big fossil fuel firms continue to plan huge investments in new fossil fuel production projects that would drive the climate past internationally agreed temperature limits. [108]
In June 2021 Dr Sven Teske and Dr Sarah Niklas from the Institute for Sustainable Futures, University of Technology Sydney found that "existing coal, oil and gas production puts the world on course to overshoot Paris climate targets." In co-operation with the Fossil Fuel Non-Proliferation Treaty Initiative they published a report entitled, Fossil Fuel Exit Strategy: An orderly wind down of coal, oil, and gas to meet the Paris Agreement. It analyses global renewable energy potential, and finds that "every region on Earth can replace fossil fuels with renewable energy to keep warming below 1.5 °C and provide reliable energy access to all." [109]
In September 2021, the first scientific assessment of the minimum amount of fossil fuels that would need to be secured from extraction per region as well as globally, to allow for a 50% probability of limiting global warming by 2050 to 1.5 °C was provided. [110] [111]
The phase-out of fossil fuels involves many challenges, and one of them is the reliance that the world currently has on them. In 2014, fossil fuels provided over 80% of the primary energy consumption of the world. [114]
Fossil fuel phase-out may lead to an increment in electricity prices, because of the new investments needed to replace their share in the electricity mix with alternative energy sources. [115] [ obsolete source ]
Another impact of a phase-out of fossil fuels is in employment. In the case of employment in the fossil fuel industry, a phase-out is logically undesired, therefore, people employed in the industry will usually oppose any measures that put their industries under scrutiny. [50] Endre Tvinnereim and Elisabeth Ivarsflaten studied the relationship between employment in the fossil fuel industry with the support to climate change policies. They proposed that one opportunity for displaced drilling employments in the fossil fuel industry could be in the geothermal energy industry. This was suggested as a result of their conclusion: people and companies in the fossil fuel industry will likely oppose measures that endanger their employment, unless they have other stronger alternatives. [116] This can be extrapolated to political interests, that can push against the phase-out of fossil fuels initiative. [117] One example is how the vote of United States Congress members is related to the preeminence of fossil fuel industries in their respective states. [118]
Other challenges include ensuring sustainable recycling, sourcing of the required materials, disruptions of existing power structures, managing variable renewable energy, developing optimal national transition policies, transforming transportation infrastructure and responsibilities of fossil fuel extraction prevention. There is active research and development on such issues. [119] [120] [121]
According to the people present at COP27 in Egypt, Saudi Arabian representatives pushed to block a call for the world to burn less oil. After objections from Saudi Arabia and a few other oil producers, summit's final statement failed to include a call for nations to phase out fossil fuels. In March 2022, at a United Nations meeting with climate scientists, Saudi Arabia, together with Russia, pushed to delete a reference to "human-induced climate change" from an official document, disputing the scientifically established fact that the burning of fossil fuels by humans is the main driver of the climate crisis. [122]
China has pledged to become carbon neutral by 2060, which would need a just transition for over 3 million workers in the coal-mining and power industry. [123] It is not yet clear whether China aims to phase-out all fossil fuel use by that date or whether a small proportion will still be in use with the carbon captured and stored. [123] In 2021, coal mining was ordered to run at maximum capacity. [124]
At the end of 2019, the European Union launched its European Green Deal. It included:
It also leans on Horizon Europe, to play a pivotal role in leveraging national public and private investments. Through partnerships with industry and member States, it will support research and innovation on transport technologies, including batteries, clean hydrogen, low-carbon steel making, circular bio-based sectors and the built environment. [128]
The European Investment Bank contributed over €81 billion to help the energy industry between 2017 and 2022, in line with EU energy policy. This comprised nearly €76 billion for initiatives related to power grids, energy efficiency, and renewable energy throughout Europe and other parts of the world. [14]
Germany has pledged to become carbon neutral by 2045. [129] Speaking at the COP28 climate summit in Dubai, German Chancellor Olaf Scholz called for a phase-out of fossil fuels, including coal, oil and natural gas, and reiterated Germany's commitment to be climate neutral by 2045, saying: "The technologies are there: wind power, photovoltaics, electric motors, green hydrogen." [130]
India is confident of exceeding Paris COP commitments. [131] In the Paris Agreement, India has committed to an Intended Nationally Determined Contributions target of achieving 40% of its total electricity generation from non-fossil fuel sources by 2030. [132]

Japan has pledged to become carbon neutral by 2050. [133]
The UK is legally committed to be carbon neutral by 2050, and moving away from the heating of homes by natural gas is likely to be the most difficult part of the country's fossil fuel phase out. [134] Alternative green recovery legislative plans have been proposed by multiple groups to phase out fossil fuels as fast as technology allows. [135]
Prominent individuals supporting a coal moratorium or phase-out:
If you're a young person looking at the future of this planet and looking at what is being done right now, and not done, I believe we have reached the stage where it is time for civil disobedience to prevent the construction of new coal plants that do not have carbon capture and sequestration.
A fossil fuel is a carbon compound- or hydrocarbon-containing material formed naturally in the Earth's crust from the buried remains of prehistoric organisms, a process that occurs within geological formations. Reservoirs of such compound mixtures, such as coal, petroleum and natural gas, can be extracted and burnt as a fuel for human consumption to provide energy for direct use, to power heat engines that can propel vehicles, or to generate electricity via steam turbine generators. Some fossil fuels are further refined into derivatives such as kerosene, gasoline and diesel, or converted into petrochemicals such as polyolefins (plastics), aromatics and synthetic resins.
Energy is sustainable if it "meets the needs of the present without compromising the ability of future generations to meet their own needs." Definitions of sustainable energy usually look at its effects on the environment, the economy, and society. These impacts range from greenhouse gas emissions and air pollution to energy poverty and toxic waste. Renewable energy sources such as wind, hydro, solar, and geothermal energy can cause environmental damage but are generally far more sustainable than fossil fuel sources.
A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal, oil, 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.
Climate change mitigation (or decarbonisation) is action to limit the greenhouse gases in the atmosphere that cause climate change. Climate change mitigation actions include conserving energy and replacing fossil fuels with clean energy sources. Secondary mitigation strategies include changes to land use and removing carbon dioxide (CO2) from the atmosphere. Current climate change mitigation policies are insufficient as they would still result in global warming of about 2.7 °C by 2100, significantly above the 2015 Paris Agreement's goal of limiting global warming to below 2 °C.
A low-carbon economy (LCE) is an economy which absorbs as much greenhouse gas as it emits. Greenhouse gas (GHG) emissions due to human activity are the dominant cause of observed climate change since the mid-20th century. There are many proven approaches for moving to a low-carbon economy, such as encouraging renewable energy transition, energy conservation, and electrification of transportation. An example are zero-carbon cities.
The energy policy of Australia is subject to the regulatory and fiscal influence of all three levels of government in Australia, although only the State and Federal levels determine policy for primary industries such as coal. Federal policies for energy in Australia continue to support the coal mining and natural gas industries through subsidies for fossil fuel use and production. Australia is the 10th most coal-dependent country in the world. Coal and natural gas, along with oil-based products, are currently the primary sources of Australian energy usage and the coal industry produces over 30% of Australia's total greenhouse gas emissions. In 2018 Australia was the 8th highest emitter of greenhouse gases per capita in the world.
A coal-fired power station or coal power plant is a thermal power station which burns coal to generate electricity. Worldwide there are over 2,400 coal-fired power stations, totaling over 2,130 gigawatts capacity. They generate about a third of the world's electricity, but cause many illnesses and the most early deaths, mainly from air pollution. World installed capacity doubled from 2000 to 2023 and increased 2% in 2023.
Low-carbon electricity or low-carbon power is electricity produced with substantially lower greenhouse gas emissions over the entire lifecycle than power generation using fossil fuels. The energy transition to low-carbon power is one of the most important actions required to limit climate change.
Energy subsidies are measures that keep prices for customers below market levels, or for suppliers above market levels, or reduce costs for customers and suppliers. Energy subsidies may be direct cash transfers to suppliers, customers, or related bodies, as well as indirect support mechanisms, such as tax exemptions and rebates, price controls, trade restrictions, and limits on market access.

Greenhouse gas emissions by Australia totalled 533 million tonnes CO2-equivalent based on greenhouse gas national inventory report data for 2019; representing per capita CO2e emissions of 21 tons, three times the global average. Coal was responsible for 30% of emissions. The national Greenhouse Gas Inventory estimates for the year to March 2021 were 494.2 million tonnes, which is 27.8 million tonnes, or 5.3%, lower than the previous year. It is 20.8% lower than in 2005. According to the government, the result reflects the decrease in transport emissions due to COVID-19 pandemic restrictions, reduced fugitive emissions, and reductions in emissions from electricity; however, there were increased greenhouse gas emissions from the land and agriculture sectors.
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.
Coal phase-out is an environmental policy intended to stop burning coal in coal-fired power plants and elsewhere, and is part of fossil fuel phase-out. Coal is the most carbon-intensive fossil fuel, therefore phasing it out is critical to limiting climate change as laid out in the Paris Agreement. The International Energy Agency (IEA) estimates that coal is responsible for over 30% of the global average temperature increase above pre-industrial levels. Some countries in the Powering Past Coal Alliance have already stopped.
In 2019, the total energy production in Indonesia is 450.79 million tonnes of oil equivalent, with a total primary energy supply of 231.14 million tonnes of oil equivalent and electricity final consumption of 263.32 terawatt-hours. From 2000 to 2021, Indonesia's total energy supply increased by nearly 60%.
Energy consumption per person in Turkey is similar to the world average, and over 85 per cent is from fossil fuels. From 1990 to 2017 annual primary energy supply tripled, but then remained constant to 2019. In 2019, Turkey's primary energy supply included around 30 per cent oil, 30 per cent coal, and 25 per cent gas. These fossil fuels contribute to Turkey's air pollution and its above average greenhouse gas emissions. Turkey mines its own lignite but imports three-quarters of its energy, including half the coal and almost all the oil and gas it requires, and its energy policy prioritises reducing imports.
An energy transition is a major structural change to energy supply and consumption in an energy system. Currently, a transition to sustainable energy is underway to limit climate change. Most of the sustainable energy is renewable energy. Therefore, another term for energy transition is renewable energy transition. The current transition aims to reduce greenhouse gas emissions from energy quickly and sustainably, mostly by phasing-down fossil fuels and changing as many processes as possible to operate on low carbon electricity. A previous energy transition perhaps took place during the Industrial Revolution from 1760 onwards, from wood and other biomass to coal, followed by oil and later natural gas.
The carbon bubble is a hypothesized bubble in the valuation of companies dependent on fossil-fuel-based energy production, resulting from future decreases in value of fossil fuel reserves as they become unusable in order to meet carbon budgets and recognition of negative externalities of carbon fuels which are not yet taken into account in a company's stock market valuation.
Fossil fuel subsidies are energy subsidies on fossil fuels. They may be tax breaks on consumption, such as a lower sales tax on natural gas for residential heating; or subsidies on production, such as tax breaks on exploration for oil. Or they may be free or cheap negative externalities; such as air pollution or climate change due to burning gasoline, diesel and jet fuel. Some fossil fuel subsidies are via electricity generation, such as subsidies for coal-fired power stations.
Coal, cars and lorries vent more than a third of Turkey's six hundred million tonnes of annual greenhouse gas emissions, which are mostly carbon dioxide and part of the cause of climate change in Turkey. The nation's coal-fired power stations emit the most carbon dioxide, and other significant sources are road vehicles running on petrol or diesel. After coal and oil the third most polluting fuel is fossil gas; which is burnt in Turkey's gas-fired power stations, homes and workplaces. Much methane is belched by livestock; cows alone produce half of the greenhouse gas from agriculture in Turkey.
World energy supply and consumption refers to the global supply of energy resources and its consumption. The system of global energy supply consists of the energy development, refinement, and trade of energy. Energy supplies may exist in various forms such as raw resources or more processed and refined forms of energy. The raw energy resources include for example coal, unprocessed oil & gas, uranium. In comparison, the refined forms of energy include for example refined oil that becomes fuel and electricity. Energy resources may be used in various different ways, depending on the specific resource, and intended end use. Energy production and consumption play a significant role in the global economy. It is needed in industry and global transportation. The total energy supply chain, from production to final consumption, involves many activities that cause a loss of useful energy.
Defying supply chain disruptions and macroeconomic headwinds, 2022 energy transition investment jumped 31% to draw level with fossil fuels

The International Energy Agency has told us that to meet the goals of the Paris Agreement, the global transition to clean power needs to move four times faster than our current pace.
Raising fuel prices to their fully efficient levels reduces projected global fossil fuel CO2 emissions 43 percent below baseline levels in 2030—or 34 percent below 2019 emissions. This reduction is in line with the 25-50 percent reduction in global greenhouse gas emissions below 2019 levels needed by 2030 to be on track with containing global warming to the Paris goal of 1.5-2C.
