Energy independence is independence or autarky regarding energy resources, energy supply and/or energy generation by the energy industry.
Energy dependence, in general, refers to mankind's general dependence on either primary or secondary energy for energy consumption (fuel, transport, automation, etc.). In a narrower sense, it may describe the dependence of one country on energy resources from another country.
Energy dependency shows the extent to which an economy relies upon imports in order to meet its energy needs. The indicator is calculated as net imports divided by the sum of gross inland energy consumption plus bunkers.
Energy dependence has been identified as one of several factors (energy sources diversification, energy suppliers diversification, energy sources fungibility, energy transport, market liquidity, energy resources, political stability, energy intensity, GDP) negatively contributing to energy security. [2] Generally, a higher level of energy dependence is associated with higher risk, because of the possible interference of trade regulations, international armed conflicts, terrorist attacks, etc. [3] [4] [5]

A study found that transition from fossil fuels to renewable energy systems reduces risks from mining, trade and political dependence because renewable energy systems don't need fuel – they depend on trade only for the acquisition of materials and components during construction. [6] Renewable energy is found to be an efficient way to ensure energy independence and security. It also supports the transition to a low carbon economy and society. [7] Ways to manage the variability of renewable energy – such as little solar power on cloudy days – include dispatchable generation and smart grids. Bioenergy hydropower and hydrogen energy could be used for such purposes alongside storage-options like batteries. [8]
Several countries are conducting extensive research and development programs around renewable energy sources like solar, wind, water, and nuclear energy in hopes to achieve energy independence. However, because solar, wind, and water cannot always be derived as an energy source, nuclear energy is seen as a near-universal alternative that is efficient, safe, and combats the climate crisis.
Under the conceived notion that the expansion of and investment in nuclear energy power plants is a key step in the goal of achieving energy independence many countries, and companies, are supporting nuclear power research efforts.
The International Thermonuclear Experimental Reactor (ITER), located in France, is an experimental tokamak nuclear fusion reactor that is a collaboration between 35 different countries. This project was launched in 2007 and still under construction today.
In 2020, the U.S. Department of Energy awarded $160 million in initial funding to TerraPower and X-energy to build advanced nuclear reactors that will be affordable to construct and operate. Both companies are expected to produce their product within 7 years. [9]
In that same tone, there are several other companies and institutions across the globe that are gaining attention from their nuclear power innovations and research efforts. Commonwealth Fusion Systems, founded in 2018, is focusing on the development of nuclear fusion. [10] In 2020, The Energy Impact Center launched its OPEN100 project, the world's first open-source blueprint for the design, construction, and financing of nuclear power plants. [11] General Fusion is a Canadian company currently developing a fusion power device, based on magnetized target fusion. [10] Flibe Energy aims to tackle the future of nuclear energy by researching and developing the liquid fluoride thorium reactor (LFTR). [10]
In addition, safe and cost-effective storage of nuclear waste in the Waste Isolation Pilot Plant and full version of this underground storage in New Mexico is important for the nuclear fuel cycle.
Energy independence is being attempted by large or resource-rich and economically-strong countries like the United States, [12] [13] Russia, [14] China [15] [16] and the Near [17] and Middle East, [18] [19] but it is so far an idealized status that at present can be only approximated by non-sustainable exploitation of a country's (non-renewable) natural resources. [20] [21] [22] [23] Another factor in reducing dependence is the addition of renewable energy sources to the energy mix. Usually, a country relies on local and global energy renewable and non-renewable resources, a mixed-model solution that presumes various energy sources and modes of energy transfer between countries like electric power transmission, oil transport (oil and gas pipelines and tankers), etc. The European dependence on Russian energy is a good example because Russia is Europe's main supplier of hard coal, crude oil, and natural gas. [24] Oil wars in and between the Middle East, Russia, and the United States that have made markets unpredictable and volatile are also a great example as to why energy advocates and experts suggest countries invest in energy independence. The international dependence of energy resources exposes countries to vulnerability in every aspect of life — countries rely on energy for food, infrastructure, security, transportation, and more.
In the Scottish Independence debate, energy independence is a key argument in favour of Scottish exit. Since the discovery of large oil fields, pro-independence proponents have used the tagline "It's Scotland's Oil" in campaigns. Scottish oil and gas production constitutes 82% of the UK's oil and gas. [25] Accordingly, economic and political independence would be followed by high-stakes energy agreements, wherein some argue the fiscal power would lie with Scotland. [26] Political independence would supposedly return decisions about the future of energy to the Scottish people, who are more likely to vote in favour of renewable energy on Scottish soil. [27] Therefore, less reliance on international gas supplies, and a focus on low-emission local energy is a key tenet of the "Building a New Scotland" prospectus promoting Scottish Independence. [28]
Nuclear power is the use of nuclear reactions to produce electricity. Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions. Presently, the vast majority of electricity from nuclear power is produced by nuclear fission of uranium and plutonium in nuclear power plants. Nuclear decay processes are used in niche applications such as radioisotope thermoelectric generators in some space probes such as Voyager 2. Generating electricity from fusion power remains the focus of international research.
Renewable energy is energy from renewable resources that are naturally replenished on a human timescale. Renewable resources include sunlight, wind, the movement of water, and geothermal heat. Although most renewable energy sources are sustainable, some are not. For example, some biomass sources are considered unsustainable at current rates of exploitation. Renewable energy is often used for electricity generation, heating and cooling. Renewable energy projects are typically large-scale, but they are also suited to rural and remote areas and developing countries, where energy is often crucial in human development.
A nuclear power plant (NPP) is a thermal power station in which the heat source is a nuclear reactor. As is typical of thermal power stations, heat is used to generate steam that drives a steam turbine connected to a generator that produces electricity. As of September 2023, the International Atomic Energy Agency reported there were 410 nuclear power reactors in operation in 31 countries around the world, and 57 nuclear power reactors under construction.
A non-renewable resource is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption. An example is carbon-based fossil fuels. The original organic matter, with the aid of heat and pressure, becomes a fuel such as oil or gas. Earth minerals and metal ores, fossil fuels and groundwater in certain aquifers are all considered non-renewable resources, though individual elements are always conserved.
Energy development is the field of activities focused on obtaining sources of energy from natural resources. These activities include the production of renewable, nuclear, and fossil fuel derived sources of energy, and for the recovery and reuse of energy that would otherwise be wasted. Energy conservation and efficiency measures reduce the demand for energy development, and can have benefits to society with improvements to environmental issues.
Alternative fuels, also known as non-conventional and advanced fuels, are fuels derived from sources other than petroleum. Alternative fuels include gaseous fossil fuels like propane, natural gas, methane, and ammonia; biofuels like biodiesel, bioalcohol, and refuse-derived fuel; and other renewable fuels like hydrogen and electricity.
Energy is sustainable if it "meets the needs of the present without compromising the ability of future generations to meet their own needs." Most definitions of sustainable energy include considerations of environmental aspects such as greenhouse gas emissions and social and economic aspects such as energy poverty. Renewable energy sources such as wind, hydroelectric power, solar, and geothermal energy are generally far more sustainable than fossil fuel sources. However, some renewable energy projects, such as the clearing of forests to produce biofuels, can cause severe environmental damage.
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.
Energy in the United Kingdom came mostly from fossil fuels in 2021. 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.
Renewable Fuels are fuels produced from renewable resources. Examples include: biofuels, Hydrogen fuel, and fully synthetic fuel produced from ambient carbon dioxide and water. This is in contrast to non-renewable fuels such as natural gas, LPG (propane), petroleum and other fossil fuels and nuclear energy. Renewable fuels can include fuels that are synthesized from renewable energy sources, such as wind and solar. Renewable fuels have gained in popularity due to their sustainability, low contributions to the carbon cycle, and in some cases lower amounts of greenhouse gases. The geo-political ramifications of these fuels are also of interest, particularly to industrialized economies which desire independence from Middle Eastern oil.
World energy resources are the estimated maximum capacity for energy production given all available resources on Earth. They can be divided by type into fossil fuel, nuclear fuel and renewable resources.
United States energy independence is the concept of eliminating or substantially reducing import of petroleum to satisfy the nation's need for energy. Some proposals for achieving energy independence would permit imports from the neighboring nations of Canada and Mexico, in which case it would be called North American energy independence. Energy independence is espoused by those who want to leave the US unaffected by global energy supply disruptions and would restrict reliance upon politically unstable states for its energy security.
Energy security is the association between national security and the availability of natural resources for energy consumption. Access to cheaper 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.
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.
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.
An energy market is a type of commodity market on which electricity, heat, and fuel products are traded. Natural gas and electricity are examples of products traded on an energy market. Other energy commodities include: oil, coal, carbon emissions, nuclear power, solar energy and wind energy. Due to the difficulty in storing and transporting energy, current and future prices in energy are rarely linked. This is because energy purchased at a current price is difficult to store and then sell at a later date. There are two types of market schemes : spot market and forward market.
The nuclear power debate is a long-running controversy about the risks and benefits of using nuclear reactors to generate electricity for civilian purposes. The debate about nuclear power peaked during the 1970s and 1980s, as more and more reactors were built and came online, and "reached an intensity unprecedented in the history of technology controversies" in some countries. In the 2010s, with growing public awareness about climate change and the critical role that carbon dioxide and methane emissions plays in causing the heating of the Earth's atmosphere, there was a resurgence in the intensity of the nuclear power debate.
Whether nuclear power should be considered a form of renewable energy is an ongoing subject of debate. Statutory definitions of renewable energy usually exclude many present nuclear energy technologies, with the notable exception of the state of Utah. Dictionary-sourced definitions of renewable energy technologies often omit or explicitly exclude mention of nuclear energy sources, with an exception made for the natural nuclear decay heat generated within the Earth.
An energy transition is a significant structural change in an energy system regarding supply and consumption. Currently, a transition to sustainable energy is underway to limit climate change. It is also called renewable energy transition. The current transition is driven by a recognition that global greenhouse-gas emissions must be drastically reduced. This process involves phasing-down fossil fuels and re-developing whole systems to operate on low carbon electricity. A previous energy transition took place during the industrial revolution and involved an energy transition from wood and other biomass to coal, followed by oil and most recently natural gas.
Energy diplomacy is a form of diplomacy, and a subfield of international relations. It is closely related to its principal, foreign policy, and to overall national security, specifically energy security. Energy diplomacy began in the first half of the twentieth century and emerged as a term during the second oil crisis as a means of describing OPEC's actions. It has since mainly focused on the securitization of energy supplies, primarily fossil fuels, but also nuclear energy and increasingly sustainable energy, on a country or bloc basis.
