Summary
Energy descent refers to retraction of oil use after the peak oil availability or voluntary energy use reductions in response to the global climate crisis.
Planning and preparing for the peak oil energy descent period has been recently promoted by David Holmgren, Rob Hopkins of the Transition Towns movement, and Richard Heinberg in the 2004 book Power down . Many who have planned and prepared for peak oil now see the climate crisis as an equally important—or greater—near term concern as compared with energy resource scarcity brought about by peak oil.
That oil reserves are dwindling is now becoming acknowledged more widely, especially after the International Energy Agency released the 2008 World Energy Outlook report. [2] Between 2007 and 2008 the IEA changed its figures for projected rate of decline in world energy supply from 3.7% a year (2007) to a projected rate of decline of 6.7% a year (2008) leading to a peak in oil supplies in 2020. [3]
In 2008 several major companies including Arup, Yahoo, and Virgin created the UK Industry Taskforce on Peak Oil and Energy Security (ITPOES) and released a report, The Oil Crunch, [4] which calls for 'collaborative contingency planning' by government and industry in the face of dwindling oil reserves.
An Energy Descent Action Plan (EDAP) is a local plan for planning and preparing for energy descent. It goes well beyond issues of energy supply, to look at across-the-board creative adaptations in the realms of health, education, economy and much more. Energy Descent Planning is a process developed by the Transition Towns Movement.
Overconsumption describes a situation where the use of a renewable natural resource exceeds its capacity to regenerate. A prolonged pattern of overconsumption leads to the eventual loss of resource bases. The term overconsumption is quite controversial in use and does not necessarily have a single unifying definition. Overconsumption is driven several factors of the current global economy, including forces like consumerism, planned obsolescence, and other unsustainable business models and can be contrasted with sustainable consumption.
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 International Energy Agency is a Paris-based autonomous intergovernmental organisation established in the framework of the Organisation for Economic Co-operation and Development (OECD) in 1974 in the wake of the 1973 oil crisis. The IEA was initially dedicated to responding to physical disruptions in the supply of oil, as well as serving as an information source on statistics about the international oil market and other energy sectors. It is best known for the publication of its annual World Energy Outlook.
Peak oil is the moment at which extraction of petroleum reaches a rate greater than that at any time in the past and starts to permanently decrease. It is related to the distinct concept of oil depletion; while global petroleum reserves are finite, the limiting factor is not whether the oil exists but whether it can be extracted economically at a given price. A secular decline in oil extraction could be caused both by depletion of accessible reserves and by reductions in demand that reduce the price relative to the cost of extraction, as might be induced to reduce carbon emissions.
Business action on climate change includes a range of activities relating to climate change, and to influencing political decisions on climate change-related regulation, such as the Kyoto Protocol. Major multinationals have played and to some extent continue to play a significant role in the politics of climate change, especially in the United States, through lobbying of government and funding of climate change deniers. Business also plays a key role in the mitigation of climate change, through decisions to invest in researching and implementing new energy technologies and energy efficiency measures.
Total energy consumption in the United Kingdom was 142.0 million tonnes of oil equivalent in 2019. In 2014, the UK had an energy consumption per capita of 2.78 tonnes of oil equivalent compared to a world average of 1.92 tonnes of oil equivalent. Demand for electricity in 2014 was 34.42 GW on average coming from a total electricity generation of 335.0 TWh.
The current energy policy of the United Kingdom is the responsibility of the Department for Business, Energy and Industrial Strategy (BEIS), after the Department of Energy and Climate Change was merged with the Department for Business, Innovation and Skills in 2016. Energy markets are also regulated by the Office of Gas and Electricity Markets (Ofgem).
Energy planning has a number of different meanings, but the most common meaning of the term is the process of developing long-range policies to help guide the future of a local, national, regional or even the global energy system. Energy planning is often conducted within governmental organizations but may also be carried out by large energy companies such as electric utilities or oil and gas producers. These oil and gas producers release greenhouse gas emissions. Energy planning may be carried out with input from different stakeholders drawn from government agencies, local utilities, academia and other interest groups.
Energy security is the association between national security and the availability of natural resources for energy consumption. Access to (relatively) cheap energy has become essential to the functioning of modern economies. However, the uneven distribution of energy supplies among countries has led to significant vulnerabilities. International energy relations have contributed to the globalization of the world leading to energy security and energy vulnerability at the same time.
Renewable energy commercialization involves the deployment of three generations of renewable energy technologies dating back more than 100 years. First-generation technologies, which are already mature and economically competitive, include biomass, hydroelectricity, geothermal power and heat. Second-generation technologies are market-ready and are being deployed at the present time; they include solar heating, photovoltaics, wind power, solar thermal power stations, and modern forms of bioenergy. Third-generation technologies require continued R&D efforts in order to make large contributions on a global scale and include advanced biomass gasification, hot-dry-rock geothermal power, and ocean energy. As of 2012, renewable energy accounts for about half of new nameplate electrical capacity installed and costs are continuing to fall.
Peak coal is the peak consumption or production of coal by a human community. Global coal consumption peaked in 2013, and had dropped slightly by the end of the 2010s. The peak of coal's share in the global energy mix was in 2008, when coal accounted for 30% of global energy production. The decline in coal use is largely driven by consumption declines in the United States and Europe, as well as developed economies in Asia. In 2019, production increases in countries such as China, Indonesia, India, Russia and Australia compensated for the falls in the United States and Europe. However, coal's structural decline continued in the 2020s.

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.
Climate change in Scotland is causing a range of impacts on Scotland, and its mitigation and adaptation is a matter for the devolved Scottish Parliament. Climate change has already changed timings of spring events such as leaf unfolding, bird migration and egg-laying. Severe effects are likely to occur on biodiversity.
Energy transition is a significant structural change in an energy system. Historically, there is a correlation between an increasing demand for energy and availability of different energy sources. The current transition to renewable energy, and perhaps other types of sustainable energy, differs as it is largely driven by a recognition that global carbon emissions must be brought to zero, and since fossil fuels are the largest single source of carbon emissions, the quantity of fossil fuels that can be produced is limited by the COP21 Paris Agreement of 2015 to keep global warming below 1.5 °C. In recent years, the term energy transition has been coined in the framework of a move towards sustainability through increased integration of renewable energy in the realm of daily life.
The desert-covered Kingdom of Saudi Arabia is the geographically largest country in the Middle East. Moreover, it accounts for 65% of the overall population of the GCC countries and 42% of its GDP. Saudi Arabia does not have a strong history in environmentalism. Thus, as the number of population increases and the industrial activity grows, environmental issues pose a real challenge to the country.
Greenhouse gas emissions by China are the largest of any country in the world both in production and consumption terms, and stem mainly from coal burning in China, including coal-fired power stations, coal mining, and blast furnaces producing iron and steel. When measuring production-based emissions, China emitted over 14 gigatonnes (Gt) CO2eq of greenhouse gases in 2019, 27% of the world total. When measuring in consumption-based terms, which adds emissions associated with imported goods and extracts those associated with exported goods, China accounts for over 27% of global emissions.
The renewable energy transition is the ongoing energy transition which aims at replacing fossil fuels with renewable energy. This transition can impact many aspects of life including the environment, society, the economy and governance.
World energy supply and consumption is global production and preparation of fuel, generation of electricity, energy transport and energy consumption. It is a basic part of economic activity. It does not include energy from food.
