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. Population growth has 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 Hubbert peak theory says that for any given geographical area, from an individual oil-producing region to the planet as a whole, the rate of petroleum production tends to follow a bell-shaped curve. It is one of the primary theories on peak oil.
Peak oil is the point when global oil production reaches its maximum rate, after which it will begin to decline irreversibly. The main concern is that global transportation relies heavily on gasoline and diesel. Transitioning to electric vehicles, biofuels, or more efficient transport could help reduce oil demand.
Colin J. Campbell was a British petroleum geologist who predicted that oil production would peak by 2007. He claimed the consequences of this are uncertain but drastic, due to the world's dependency on fossil fuels for the vast majority of its energy. His theories have received wide attention but are disputed and have not significantly changed governmental energy policies at this time. To deal with declining global oil production, he proposed the Rimini protocol.
Richard William Heinberg is an American journalist and educator who has written extensively on energy, economic, and ecological issues, including oil depletion. He is the author of 14 books, and presently serves as the senior fellow at the Post Carbon Institute.
The End of Suburbia: Oil Depletion and the Collapse of The American Dream is a 2004 documentary film concerning peak oil and its implications for the suburban lifestyle, written and directed by Toronto-based filmmaker Gregory Greene.
The Party’s Over: Oil, War and the Fate of Industrial Societies, by Richard Heinberg, is an introduction to the concept of peak oil and petroleum depletion.
Oil depletion is the decline in oil production of a well, oil field, or geographic area. The Hubbert peak theory makes predictions of production rates based on prior discovery rates and anticipated production rates. Hubbert curves predict that the production curves of non-renewing resources approximate a bell curve. Thus, according to this theory, when the peak of production is passed, production rates enter an irreversible decline.
The Rimini Protocol is a proposal made by the geologist Colin Campbell. It is intended to stabilise oil prices and minimise the effects of peak oil. It is named after the XXIX. Annual Conference The Economics of the Noble Path: Fraternal Rights, the Convival Society, Fair Shares for All of the Pio Manzù International Research Centre in Rimini, Italy on 18-20 October 2003, where Campbell presented his idea of an oil depletion protocol. A few months later, he published together with Kjell Aleklett, the head of the Uppsala Hydrocarbon Depletion Study Group, a slightly refined text under the name Uppsala Protocol.
Ali Morteza Samsam Bakhtiari was an Iranian author and oil expert employed by the National Iranian Oil Company (NIOC). He held a number of senior positions with this organization beginning in 1971. He was also an adviser to the Oil Depletion Analysis Centre.
Chris Skrebowski is a well-known commentator on the oil industry and an expert on global oil supply. He is the founding Director of Peak Oil Consulting and consulting editor for Petroleum Review, the magazine of the UK Energy Institute. Skrebowski is also a founding member of the Association for the Study of Peak Oil and Gas (ASPO) and sits on the board of the Oil Depletion Analysis Centre (ODAC). He is a Fellow of the Energy Institute and advises the All Party Parliamentary Group on Peak Oil and Gas (APPGOPO).
The price of oil, or the oil price, generally refers to the spot price of a barrel of benchmark crude oil—a reference price for buyers and sellers of crude oil such as West Texas Intermediate (WTI), Brent Crude, Dubai Crude, OPEC Reference Basket, Tapis crude, Bonny Light, Urals oil, Isthmus, and Western Canadian Select (WCS). Oil prices are determined by global supply and demand, rather than any country's domestic production level.
Jean H. Laherrère is a French petroleum engineer and consultant, best known as the co-author of an influential 1998 Scientific American article entitled The End of Cheap Oil.
David Fleming was an English economist, cultural historian and writer on environmental issues, based in London.
Dale Allen Pfeiffer is a geologist and writer from Michigan, U.S. who investigated and wrote about energy depletion and potential future resource wars. He also wrote about class war, sustainability, direct action and the environment. He is also an anarchist activist and a member of the Industrial Workers of the World. In 1999, he was one of the organizers of a hunger strike to provide medical care for the incarcerated Leonard Peltier.
Peak coal is the peak consumption or production of coal by a human community. Peak coal can be driven by peak demand or peak supply. Historically, it was widely believed that the supply-side would eventually drive peak coal due to the depletion of coal reserves. However, since the increasing global efforts to limit climate change, peak coal has been driven by demand. This is due in large part to the rapid expansion of natural gas and renewable energy. As of 2024 over 40% of all energy sector CO2 emissions are from coal, and many countries have pledged to phase-out coal.
Predicting the timing of peak oil involves estimation of future production from existing oil fields as well as future discoveries. The initial production model was Hubbert peak theory, first proposed in the 1950s. Since then, many experts have tried to forecast peak oil.
Sustainability measurement is a set of frameworks or indicators used to measure how sustainable something is. This includes processes, products, services and businesses. Sustainability is difficult to quantify. It may even be impossible to measure as there is no fixed definition. To measure sustainability, frameworks and indicators consider environmental, social and economic domains. The metrics vary by use case and are still evolving. They include indicators, benchmarks and audits. They include sustainability standards and certification systems like Fairtrade and Organic. They also involve indices and accounting. They can include assessment, appraisal and other reporting systems. The metrics are used over a wide range of spatial and temporal scales. For organizations, sustainability measures include corporate sustainability reporting and Triple Bottom Line accounting. For countries, they include estimates of the quality of sustainability governance or quality of life measures, or environmental assessments like the Environmental Sustainability Index and Environmental Performance Index. Some methods let us track sustainable development. These include the UN Human Development Index and ecological footprints.
Post Carbon Institute (PCI) is a think tank which provides information and analysis on climate change, energy scarcity, and other issues related to sustainability and long term community resilience. Its Fellows specialize in various fields related to the organization's mission, such as fossil fuels, renewable energy, food, water, and population. Post Carbon is incorporated as a 501(c)(3) non-profit organization and is based in Corvallis, Oregon, United States.
Peak minerals marks the point in time when the largest production of a mineral will occur in an area, with production declining in subsequent years. While most mineral resources will not be exhausted in the near future, global extraction and production has become more challenging. Miners have found ways over time to extract deeper and lower grade ores with lower production costs. More than anything else, declining average ore grades are indicative of ongoing technological shifts that have enabled inclusion of more 'complex' processing – in social and environmental terms as well as economic – and structural changes in the minerals exploration industry and these have been accompanied by significant increases in identified Mineral Reserves.
