The electricity sector in China is the world's largest national power system, consuming 9.85 trillion kWh in 2024 and leading both wind and solar construction.

The electricity sector in India, also called the Indian power sector, supplies the world's third-largest electricity market, with about 462,000 MW installed capacity and roughly 2,000 TWh generated annually.

Electricity sector in Mexico

The electricity sector in Mexico is led by the Federal Electricity Commission (CFE), which must supply at least 54 percent of the power after a 2025 reform reversed the 2013 liberalization.

Electricity sector in the European Union

The electricity sector in the European Union is a coupled internal power market in which member states keep their own energy mix, with renewables reaching half of consumption in 2025.

Electride

An electride is an ionic crystal in which electrons unbound to any nucleus act as the anions, first synthesized in 1983 and valued in catalysis and electronics.

Electrified Powertrain Flight Demonstration

The Electrified Powertrain Flight Demonstration was a NASA program that flight-tested hybrid electric aircraft propulsion with GE Aerospace and magniX; GE's Saab 340B became the first hybrid electric aircraft to fly above 30,000 feet.

Electrify America

Electris Mons

Electris Mons is a 104.47 km mountain on Mars at 45.67°S, 152.73°E, IAU-approved August 12, 2013, named for the classical albedo feature Electris; it lies in quadrangle MC-29 near the Electris deposit.

Electro (Marvel Comics)

Electro (Maxwell "Max" Dillon) is a Marvel Comics supervillain and Spider-Man enemy, created by Stan Lee and Steve Ditko, debuting in Amazing Spider-Man #9 (1964) as a lightning-struck lineman with electrical powers and a founding Sinister Six member.

Electro (music)

Electro (electro-funk or electro-boogie) is an early 1980s electronic dance and hip-hop genre built on the Roland TR-808, broken syncopated beats, and vocoder vocals, founded by Afrika Bambaataa's 1982 "Planet Rock" and ancestor of Miami bass, freestyle, and Detroit techno.

Electro house

Electro house, a house music subgenre from around 2002 fusing tech house and electroclash, runs 125-135 BPM with distorted saw basslines, sidechain pumping, and drops; pioneers Benny Benassi, D. Ramirez, deadmau5; offshoots big room, complextro, dutch house.

Electro-absorption modulated laser

An electro-absorption modulated laser (EML) combines a continuous-wave DFB laser and an electro-absorption modulator on a single indium phosphide chip, giving lower chirp and higher bandwidth than directly modulated lasers.

Electro-absorption modulator

An electro-absorption modulator (EAM) is a semiconductor device that controls light transmission by applying an electric field, enabling bandwidths above 50 GHz at low drive voltages.

Electro-chemo-mechanical contact loss in all-solid-state cells

Electro-chemo-mechanical contact loss in all-solid-state cells is degradation in which electrode volume change during cycling breaks solid-solid contact, and the rigid solid electrolyte cannot re-wet the surface.

Electro-diesel locomotive

An electro-diesel locomotive, also called a dual-mode or bi-mode locomotive, draws power from overhead wires or a third rail, plus an onboard diesel engine for non-electrified lines.

Electro-diesel multiple unit

An electro-diesel multiple unit is a self-propelled train using both diesel and electric power to run on electrified and non-electrified track. The Southern Region of British Railways first used them in 1956.

Electro-Fenton process

The electro-Fenton process is an electrochemical advanced oxidation process for water treatment that generates hydrogen peroxide at a cathode, producing hydroxyl radicals that degrade persistent pollutants.

Electro-fermentation

Electro-fermentation is a bioproduction method that combines microbial fermentation with a polarized electrode interface, acting as electron donor, acceptor, or redox controller to change yield and products.

Electro-Motive Diesel

Electro-Motive Diesel, also known as EMD, is an American locomotive maker founded in 1922 that led the switch from steam to diesel and has been owned by Caterpillar's Progress Rail since 2010.

Electro-optic modulator

An electro-optic modulator (EOM) is a device that uses the Pockels effect to control light's phase, amplitude, polarization, or frequency with an applied voltage, often built from lithium niobate.

Electro-optic sampling

Electro-optic sampling is a technique that uses the Pockels effect in an electro-optic crystal to measure the electric field waveform of ultrashort light or terahertz pulses.

Electro-oxidation

Electro-oxidation (EO) is an electrochemical method that applies a potential to an electrode to generate oxidizing species such as hydroxyl radical, used for organic electrosynthesis and degrading pollutants in water and wastewater.

Electro-swing adsorption

Electro-swing adsorption (ESA) is a carbon capture process in which electricity, rather than heat or pressure, drives the switch between adsorption and desorption of CO₂, covering Joule-heated sorbents and faradaic electrochemical cells.

Electro-swing carbon capture

Electro-swing carbon capture is a family of CO2 separation methods driven by electrochemical changes rather than heat or pressure, spanning faradaic reactive adsorption and electric swing adsorption.

Electro-swing CO2 capture

Electro-swing CO2 capture is a family of carbon capture methods in which a solid electrode adsorbs CO2 when negatively charged and releases it when the charge is reversed.

Electroacupuncture

Electroacupuncture is a treatment technique in which a small electrical current is passed between pairs of acupuncture needles inserted into the body, used in clinical medicine mainly for pain relief.

Electroanalytical methods

Electroanalytical methods, also called electroanalytical chemistry, are analytical techniques that measure potential, current, charge, or conductance in an electrochemical cell to determine a sample's composition.

Electroanatomic mapping

Electroanatomic mapping is a cardiac electrophysiology technique that builds navigable 3D maps of electrical activity in the heart chambers to guide diagnosis and catheter ablation of arrhythmias.

Electroantennography

Electroantennography (EAG) is an electrophysiological technique recording the voltage an insect antenna generates in response to odor, introduced by Dietrich Schneider in 1957 and widely used in chemical ecology.
