Energy management (aeronautics)

Energy management in aeronautics is the planning and control of airspeed, altitude, thrust, drag, and trajectory to meet flightpath targets. Poor energy management contributes to the most common fatal aviation accidents.

Energy Market Regulatory Authority (Turkey)

The Energy Market Regulatory Authority (EMRA; Turkish: Enerji Piyasası Düzenleme Kurumu, EPDK) is Turkey's independent energy regulator, handling licensing and tariffs for electricity, natural gas, petroleum, and LPG markets.

Energy medicine

Energy medicine: complementary practices based on an invisible biofield or vital energy, including Reiki, Therapeutic Touch, and Healing Touch; unvalidated premise, mixed clinical evidence, strongest signal for pain reduction.

Energy method

The energy method is a technique in the analysis of partial differential equations in which an estimate for a nonnegative quantity, called an energy, is derived from the equation itself.

Energy minimization

Energy minimization, also called geometry optimization, is the computational search for a local minimum of potential energy on a potential energy surface, using algorithms such as L-BFGS.

Energy Northwest

Energy Northwest, formerly the Washington Public Power Supply System, is a Washington joint operating agency formed in 1957 that generates carbon-free electricity at cost for member utilities.

Energy Performance Certificate

An Energy Performance Certificate rates a building's energy efficiency on an A to G scale and recommends improvements, required when buildings are sold or rented across Europe.

Energy Performance Contracting

Energy performance contracting (EPC) is a service contract in which an energy service company guarantees specified energy savings, letting clients pay for improvements from the savings.

Energy Performance of Buildings Directive

The Energy Performance of Buildings Directive (EPBD) is the European Union's main law on building energy performance, first adopted in 2002 and requiring all new buildings to be zero-emission from 2030.

Energy Plant Collection

Energy Plant Collection (能源植物园) is a living collection at Xishuangbanna Tropical Botanical Garden, CAS, built in 2010 on about 85 mu, holding 360+ energy plant species in 52 families across six biomass-type zones including fuelwood, starch, fiber, oil, and hydrocarbon plants.

Energy Policy Act of 2005

The Energy Policy Act of 2005 is a United States federal law, signed by President George W. Bush on August 8, 2005, setting policy on energy production, efficiency, and electricity regulation.

Energy Policy and Conservation Act

The Energy Policy and Conservation Act (EPCA) is a 1975 United States federal law that created the Strategic Petroleum Reserve and CAFE fuel economy standards.

Energy policy of India

India's energy policy governs how India's central and state governments manage energy production, pricing, and decarbonization, pursuing 500 GW of non-fossil capacity by 2030 and net zero by 2070.

Energy policy of the European Union

The energy policy of the European Union is the body of EU law and funding combining an internal energy market with decarbonisation, under a shared competence since 1951.

Energy price cap

The energy price cap is a maximum on unit rates and standing charges that Ofgem sets for domestic energy tariffs in Great Britain, in force since January 2019.

Energy profile (chemistry)

An energy profile is a chemistry diagram of the relative energies of reactants, transition states, intermediates, and products, with peak heights giving the activation energies that determine a reaction's rate.

Energy recovery linac

An energy recovery linac (ERL) is a linear particle accelerator whose spent electron beam is decelerated in the same cavities that accelerated it, recovering most of its energy for reuse.

Energy recovery ventilator

An energy recovery ventilator (ERV) is a balanced mechanical ventilation device that supplies fresh air to a building while transferring heat and moisture between air streams.

Energy release rate

The energy release rate, usually written G, is a fracture mechanics quantity measuring the energy released per unit of new crack surface as a crack extends.

Energy Research Institute of the Russian Academy of Sciences (Институт энергетических исследований Российской академии наук)

Energy Research Institute of the Russian Academy of Sciences (ИНЭИ РАН, ERI RAS), founded 1985 in Moscow: RAS institute for energy system research and forecasting, known for SCANER models and the recurring Forecast of Energy Development of Russia and the World.

Energy security

Energy security is the ability of a country to ensure uninterrupted energy availability at affordable prices, a concept originating in oil policy after the 1973 oil embargo.

Energy Security Strategy (Australia)

Australia's Energy Security Strategy is the set of Commonwealth laws, market rules, and reserves keeping liquid fuel, electricity, and gas available through disruptions and the transition to net zero.

Energy Star

Energy Star, also known as the Energy Star rating, is a voluntary US government labeling program launched by the EPA in 1992 that identifies energy-efficient products, homes, and buildings.

Energy storage

Energy storage, also called electricity storage, holds energy for later use, led worldwide in 2025 by lithium-ion batteries at 56% of capacity and pumped hydro at 43%.

Energy Storage Grand Challenge

The Energy Storage Grand Challenge (ESGC) is a US Department of Energy program announced in January 2020 to coordinate energy storage research, development, commercialization, and manufacturing.

Energy subsidy

An energy subsidy is any government action lowering energy costs, from direct cash payments to tax breaks and uncharged environmental damage; estimates range into the trillions of dollars.

Energy tank method

The energy tank method is a passivity-based control technique that couples a virtual energy reservoir to a robot controller, keeping the closed loop passive during physical human-robot interaction.
