136-690: A Tank-to-wheel basis. They have better fuel economy than conventional internal combustion engine vehicles but are hampered by range or maximum distance attainable before discharging the battery. The electric car batteries are their main cost. They provide a 0% to 99.9% reduction in CO 2 emissions compared to an ICE (gasoline, diesel) vehicle, depending on the source of electricity. Hybrid cars may be partly fossil fuel (or biofuel) powered and partly electric or hydrogen-powered. Most combine an internal combustion engine with an electric engine, though other variations too exist. The internal combustion engine

204-412: A car . Some laws have limits on top speeds, power of the motors, range, etc. while others do not. Horse and carriage are just one type of animal propelled vehicle. Once a common form of transportation, they became far less common as cities grew and automobiles took their place. In dense cities, the waste produced by large numbers of transportation animals was a significant health problem. Oftentimes

272-522: A fuel for human consumption to provide energy for direct use (such as for cooking , heating or lighting ), to power heat engines (such as steam or internal combustion 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 . The origin of fossil fuels

International policy, in the form of United Nations ' sustainable development goals for affordable and clean energy and climate action , as well as the Paris Climate Agreement , is designed to facilitate this transition at a global level. In 2021, the International Energy Agency concluded that no new fossil fuel extraction projects could be opened if

408-410: A complex mixture of high-molecular weight organic compounds, which yield synthetic crude oil when heated ( pyrolyzed ). With additional processing, they can be employed instead of other established fossil fuels. During the 2010s and 2020s there was disinvestment from exploitation of such resources due to their high carbon cost relative to more easily-processed reserves. Prior to the latter half of

476-425: A lesser extent oil and its derivatives, contributes to atmospheric particulate matter , smog and acid rain . Air pollution from fossil fuels in 2018 has been estimated to cost US$ 2.9 trillion, or 3.3% of the global gross domestic product (GDP). Climate change is largely driven by the release of greenhouse gases like CO 2 , and the burning of fossil fuels is the main source of these emissions. In most parts of

544-519: A lot geographically. Studies suggest that when taking into account both production and operation, electric cars would cause more emissions in economies where production of electricity is not clean, e.g., it is mostly coal based. For this reason, some studies found that driving electric cars is less environmentally damaging in western US states than in eastern ones, where less electricity is produced using cleaner sources. Similarly, in countries like India, Australia or China, where large portion of electricity

612-532: A move away from hydrocarbon fuels and from our present automobile and highway paradigm. The European Union is promoting the marketing of greener cars via a combination of binding and non-binding measures. As of April 2010, 15 of the 27 member states of the European Union provide tax incentives for electrically chargeable vehicles and some alternative fuel vehicles , which includes all Western European countries except Italy and Luxembourg , plus

680-761: A process known as catagenesis . Despite these heat-driven transformations, the energy released in combustion is still photosynthetic in origin. Terrestrial plants tended to form coal and methane. Many of the coal fields date to the Carboniferous period of Earth's history . Terrestrial plants also form type III kerogen , a source of natural gas. Although fossil fuels are continually formed by natural processes, they are classified as non-renewable resources because they take millions of years to form and known viable reserves are being depleted much faster than new ones are generated. Fossil fuels have been important to human development because they can be readily burned in

748-627: A reason for growing food prices, particularly US Bio-ethanol fuel production which has affected maize prices. In order to have a low environmental impact, biofuels should be made only from waste products, or from new sources like algae .

816-531: A regular basis in order to promote green vehicles and other " green technology ". These sleek driver-only vehicles can travel long distances at highway speeds using only the electricity generated instantaneously from the sun. A conventional vehicle can become a greener vehicle by mixing in renewable fuels or using less carbon intensive fossil fuel . Typical gasoline -powered cars can tolerate up to 10% ethanol . Brazil manufactured cars that run on neat ethanol, though there were discontinued. Another available option

884-406: A result of anaerobic decomposition . Over geological time this organic matter , mixed with mud , became buried under further heavy layers of inorganic sediment. The resulting high temperature and pressure caused the organic matter to chemically alter , first into a waxy material known as kerogen , which is found in oil shales , and then with more heat into liquid and gaseous hydrocarbons in

952-483: A result of synthetic nitrogen fertilizer use. According to head of a fertilizers commodity price agency, "50% of the world's food relies on fertilisers." The burning of fossil fuels has a number of negative externalities  – harmful environmental impacts where the effects extend beyond the people using the fuel. These effects vary between different fuels. All fossil fuels release CO 2 when they burn, thus accelerating climate change . Burning coal, and to

1020-478: A vehicle is a better environmental performer relative to other vehicles. This US EPA designation is arrived at by taking into account a vehicle's Air Pollution Score and Greenhouse Gas Score. Higher Air Pollution Scores indicate vehicles that emit lower amounts of pollutants that cause smog relative to other vehicles. Higher Greenhouse Gas Scores indicate vehicles that emit lower amounts of carbon dioxide and have improved fuel economy relative to other vehicles. To earn

1088-588: Is a flexible-fuel vehicle which allows any blend of gasoline and ethanol, up to 85% in North America and Europe, and up to 100% in Brazil. Another existing option is to convert a conventional gasoline-powered to allow the alternative use of CNG . Pakistan , Argentina , Brazil , Iran , India , Italy , and China have the largest fleets of natural gas vehicles in the world. Diesel -powered vehicles can often transition completely to biodiesel , though

1156-521: Is a net increase of many billion tonnes of atmospheric CO 2 per year. Although methane leaks are significant, the burning of fossil fuels is the main source of greenhouse gas emissions causing global warming and ocean acidification . Additionally, most air pollution deaths are due to fossil fuel particulates and noxious gases, and it is estimated that this costs over 3% of the global gross domestic product and that fossil fuel phase-out will save millions of lives each year. Recognition of

1224-507: Is an attempt to reduce climate change by exerting social, political, and economic pressure for the institutional divestment of assets including stocks, bonds, and other financial instruments connected to companies involved in extracting fossil fuels . Fossil fuel divestment campaigns emerged on college and university campuses in the United States in 2011 with students urging their administrations to turn endowment investments in

1292-593: Is driven. Norwegian Consumer Ombudsman official Bente Øverli stated that "Cars cannot do anything good for the environment except less damage than others." Based on this opinion, Norwegian law severely restricts the use of " greenwashing " to market automobiles, strongly prohibiting advertising a vehicle as being environmentally friendly, with large fines issued to violators. Some studies try to compare environmental impact of electric and petrol vehicles over complete life cycle, including production, operation, and dismantling. In general, results differ vastly dependent on

1360-443: Is more important than a focus on a single factor such as energy efficiency. Cars with similar production of energy costs can be obtained, during the life of the car (operational phase), large reductions in energy costs through several measures: Green vehicles include vehicles types that function fully or partly on alternative energy sources other than fossil fuel or less carbon-intensive than gasoline or diesel. Another option

1428-450: Is no such thing as an environmentally friendly car. The use of vehicles with increased fuel efficiency is usually considered positive in the short term but criticism of any hydrocarbon-based personal transport remains. The Jevons paradox suggests that energy efficiency programs are often counter-productive, even increasing energy consumption in the long run. Many environmental researchers believe that sustainable transport may require

1496-404: Is now considered a very valuable resource. Natural gas deposits are also the main source of helium . Heavy crude oil , which is much more viscous than conventional crude oil, and oil sands , where bitumen is found mixed with sand and clay, began to become more important as sources of fossil fuel in the early 2000s. Oil shale and similar materials are sedimentary rocks containing kerogen ,

1564-452: Is often either a gasoline or Diesel engine (in rare cases a Stirling engine may even be used ). They are more expensive to purchase but cost redemption is achieved in a period of about 5 years due to better fuel economy. Compressed air cars , stirling-powered vehicles, and Liquid nitrogen vehicles are less polluting than an electrical vehicles, since the vehicle and its components are environment friendly . Solar car races are held on

1632-537: Is produced by using coal, driving electric vehicles would cause larger environmental damage than driving petrol vehicles. When justifying use of electric cars over petrol cars, these kinds of studies do not provide sufficiently clear results. Environmental impact is calculated based on fuel mix used to produce electricity that powers electric cars. However, when a gas vehicle is replaced by an equivalent electric vehicle, additional power must be installed in electrical grid. This additional capacity would normally not be based on

1700-501: Is sometimes transported by diesel-powered locomotives, while crude oil is typically transported by tanker ships, requiring the combustion of additional fossil fuels. A variety of mitigating efforts have arisen to counter the negative effects of fossil fuels. This includes a movement to use alternative energy sources, such as renewable energy . Environmental regulation uses a variety of approaches to limit these emissions; for example, rules against releasing waste products like fly ash into

1768-528: Is the anaerobic decomposition of buried dead organisms, whose organic molecules were produced by photosynthetic carbon fixation and sequestered / biomagnified by the food web , creating an underground carbon sink . The conversion from these organic materials to high-carbon fossil fuels typically requires a geological process of millions of years. Due to the length of time it takes nature to form them, fossil fuels are considered non-renewable resources . In 2022, over 80% of primary energy consumption in

1836-601: Is the lowest emission fuel available for diesel engines. Diesel engines are the most efficient car internal combustion engines. Biodiesel is the only fuel allowed in some North American national parks because spillages will completely bio-degrade within 21 days. Biodiesel and vegetable oil fuelled , diesel engined vehicles have been declared amongst the greenest in the US Tour de Sol competition. This presents problems, as biofuels can use food resources in order to provide mechanical energy for vehicles. Many experts point to this as

1904-424: Is the speed limitations, and how far one can travel before getting exhausted. Vehicle emissions contribute to the increasing concentration of gases linked to climate change . In order of significance, the principal greenhouse gases associated with road transport are carbon dioxide (CO 2 ), methane (CH 4 ) and nitrous oxide (N 2 O). Road transport is the third largest source of greenhouse gases emitted in

1972-560: Is the use of alternative fuel composition in conventional fossil fuel-based vehicles, making them function partially on renewable energy sources. Other approaches include personal rapid transit , a public transportation concept that offers automated, on-demand, non-stop transportation on a network of specially built guideways. Examples of vehicles with reduced petroleum consumption include electric cars , plug-in hybrids and fuel cell -powered hydrogen cars . Electric cars are typically more efficient than fuel cell -powered vehicles on

2040-523: Is used in the construction of roads . The energy for the Green Revolution was provided by fossil fuels in the form of fertilizers (natural gas), pesticides (oil), and hydrocarbon -fueled irrigation . The development of synthetic nitrogen fertilizer has significantly supported global population growth ; it has been estimated that almost half of the Earth's population are currently fed as

2108-651: Is waging war on nature. This is suicidal. Nature always strikes back – and it is already doing so with growing force and fury." He also claimed there is still cause for hope, anticipating the US plan to join other large emitters like China and the EU in adopting targets to reach net zero emissions by 2050. Fossilflation is a term that describes the impact of fossil fuels on inflation . According to Vox in August 2022 , "Economists have pointed to energy prices as

As of 2021 , policy researchers estimate that substantially more money is spent on fossil fuel subsidies than on environmentally harmful agricultural subsidies or environmentally harmful water subsidies . The International Energy Agency says: "High fossil fuel prices hit

2448-406: The internal combustion engine and its use in automobiles and trucks greatly increased the demand for gasoline and diesel oil , both made from fossil fuels. Other forms of transportation, railways and aircraft, also require fossil fuels. The other major use for fossil fuels is in generating electricity and as feedstock for the petrochemical industry . Tar , a leftover of petroleum extraction,

2516-496: The 18th century, windmills and watermills provided the energy needed for work such as milling flour, sawing wood or pumping water, while burning wood or peat provided domestic heat. The wide-scale use of fossil fuels, coal at first and petroleum later, in steam engines enabled the Industrial Revolution . At the same time, gas lights using natural gas or coal gas were coming into wide use. The invention of

2584-451: The 2021 Tesla Model 3 Standard Range Plus RWD became the most efficient EPA-certified vehicle considering all fuels and all years, surpassing the 2020 Tesla Model 3 Standard Range Plus and 2019 Hyundai Ioniq Electric . Several authors also include conventional motor vehicles with high fuel economy , as they consider that increasing fuel economy is the most cost-effective way to improve energy efficiency and reduce carbon emissions in

2652-418: The 21st century. Combustion of fossil fuels generates sulfuric and nitric acids , which fall to Earth as acid rain, impacting both natural areas and the built environment. Monuments and sculptures made from marble and limestone are particularly vulnerable, as the acids dissolve calcium carbonate . Fossil fuels also contain radioactive materials, mainly uranium and thorium , which are released into

2720-627: The COVID-19 pandemic, some argued for the possibility of a base effect phenomenon due to cheaper than normal prices, such as for oil, at the onset of the pandemic, followed by above-average prices which exacerbated the perceived inflation. While not expected to provide much short-term relief, the Inflation Reduction Act seeks to make the United States less dependent on fossil fuels and their ability to cause inflation in

2856-730: The UK as a direct result of air pollution. According to the World Health Organization , up to 13,000 deaths per year among children (aged 0–4 years) across Europe are directly attributable to outdoor pollution. The organization estimates that if pollution levels were returned to within EU limits, more than 5,000 of these lives could be saved each year. Hybrid taxi fleet operators in New York have also reported that reduced fuel consumption saves them thousands of dollars per year. A study by CNW Marketing Research suggested that

2924-494: The UK, and accounts for about 27% of total emissions, and 33% in the United States. Of the total greenhouse gas emissions from transport, over 85% are due to CO 2 emissions from road vehicles. The transport sector is the fastest growing source of greenhouse gases. Vehicle pollutants have been linked to human ill health including the incidence of respiratory and cardiopulmonary disease and lung cancer. A 1998 report estimated that up to 24,000 people die prematurely each year in

2992-538: The United States production. In addition to the effects that result from burning, the harvesting, processing, and distribution of fossil fuels also have environmental effects. Coal mining methods, particularly mountaintop removal and strip mining , have negative environmental impacts, and offshore oil drilling poses a hazard to aquatic organisms. Fossil fuel wells can contribute to methane release via fugitive gas emissions . Oil refineries also have negative environmental impacts, including air and water pollution. Coal

3060-465: The atmosphere. In December 2020, the United Nations released a report saying that despite the need to reduce greenhouse emissions, various governments are " doubling down " on fossil fuels, in some cases diverting over 50% of their COVID-19 recovery stimulus funding to fossil fuel production rather than to alternative energy. The UN secretary general António Guterres declared that "Humanity

3128-540: The atmosphere. In 2000, about 12,000 tonnes of thorium and 5,000 tonnes of uranium were released worldwide from burning coal. It is estimated that during 1982, US coal burning released 155 times as much radioactivity into the atmosphere as the Three Mile Island accident . Burning coal also generates large amounts of bottom ash and fly ash . These materials are used in a wide variety of applications (see Fly ash reuse ), utilizing, for example, about 40% of

3196-570: The best green cars of a given year . The following table presents a selection of the annual top pickings. Dedicated electric and green vehicle motor shows: Fossil fuel 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 ( animals , plants or planktons ), 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

3264-711: The data show that fossil fuels cause the highest levels of greenhouse gas emissions and are the most dangerous for human health. In contrast, modern renewable energy sources appear to be safer for human health and cleaner. The death rates from accidents and air pollution in the EU are as follows per terawatt-hour (TWh): As the data shows, coal, oil, natural gas, and biomass cause higher death rates and higher levels of greenhouse gas emissions than hydropower, nuclear energy, wind, and solar power. Scientists propose that 1.8 million lives have been saved by replacing fossil fuel sources with nuclear power. Fossil fuel divestment or fossil fuel divestment and investment in climate solutions

3332-931: The economy. Moody's estimates that by 2030, the bill could reduce the typical American household's spending on energy by more than $ 300 each year, in 2022 dollars. Environmental pollution from fossil fuels impacts humans because particulates and other air pollution from fossil fuel combustion may cause illness and death when inhaled. These health effects include premature death, acute respiratory illness, aggravated asthma, chronic bronchitis and decreased lung function. The poor, undernourished, very young and very old, and people with preexisting respiratory disease and other ill health are more at risk. Global air pollution deaths due to fossil fuels have been estimated at over 8 million people (2018, nearly 1 in 5 deaths worldwide) at 10.2 million (2019), and 5.13 million excess deaths from ambient air pollution from fossil fuel use (2023). While all energy sources inherently have adverse effects,

3400-422: The extra energy cost of manufacture, shipping, disposal, and the short lives of some of these types of vehicle (particularly gas-electric hybrid vehicles ) outweighs any energy savings made by their using less petroleum during their useful lifespan. This type of argument is the long smokestack argument. Critics of the report note that the study prorated all of Toyota's hybrid research-and-development costs across

3468-422: The food is produced for them using diesel powered tractors, and thus there is some environmental impact as a result of their use.

Big Oil companies such as ExxonMobil , Shell , BP , TotalEnergies , Chevron Corporation , and ConocoPhillips are among the largest corporations associated with the fossil fuels lobby. The American Petroleum Institute is a powerful industry lobbyist for Big Oil with significant influence in Washington, D.C. In Australia, Australian Energy Producers , formerly known as

3808-493: The main reason for high inflation," noting that "energy prices indirectly affect virtually every part of the economy". Sectors that raise prices significantly as a result of higher fossil fuel prices include transportation, food, and shipping. Mark Zandi of Moody's says that fossil fuel prices have driven every big episode of inflation since WWII. The economic impact of the Russian Invasion of Ukraine in 2022

3876-463: The open atmosphere to produce heat. The use of peat as a domestic fuel predates recorded history. Coal was burned in some early furnaces for the smelting of metal ore , while semi-solid hydrocarbons from oil seeps were also burned in ancient times, they were mostly used for waterproofing and embalming . Commercial exploitation of petroleum began in the 19th century. Natural gas, once flared-off as an unneeded byproduct of petroleum production,

When considering only CO 2 emissions, it is noted that production of electric cars generate about twice as much emissions as that of internal combustion cars. However, emissions of CO 2 during operation are much larger (on average) than during production. For electric cars, emissions caused during operation depend on energy sources used to produce electricity and thus vary

4080-474: The relatively small number of Priuses on the road, rather than using the incremental cost of building a vehicle; used109,000 miles (175,000 km) for the length of life of a Prius (Toyota offers a 150,000-mile (240,000 km) warranty on the Prius' hybrid components, including the battery), and calculated that a majority of a car's cradle-to-grave energy gets expended during the vehicle's production, not while it

4148-1025: The same ratios of energy sources ("clean" versus fossil fuels ) than the current capacity. Only when additional electricity production capacity installed to switch from petrol to electric vehicles would predominantly consist of clean sources, switch to electric vehicles could reduce environmental damage. Another common problem in methodology used in comparative studies is that it only focuses on specific kinds of environmental impact. While some studies focus only on emission of gas pollutants over life cycle or only on greenhouse gas emissions such as CO 2 , comparison should also account for other environmental impacts such as pollutants released otherwise during production and operation or ingredients that can not be effectively recycled. Examples include use of lighter high performing metals, lithium batteries and more rare metals in electric cars, which all have high environmental impact. A study that also looked at factors other than energy consumption and carbon emissions has suggested that there
