Accumulateur nickel-hydrure métalliqueUn accumulateur nickel-hydrure métallique ou NiMH (de l'anglais nickel-metal hydride) est un accumulateur électrique rechargeable utilisant de l'hydrure métallique (composé permettant de stocker de l'hydrogène) et de l'oxyhydroxyde de nickel comme l'électrode. La technologie NiMH est extrêmement répandue dans les accumulateurs portables d'usage courant : les modèles AA/HR6 dont la capacité peut atteindre pour les plus performants ; les modèles AAA/HR3 dont la capacité maximale est de .
Groupe électrogèneUn groupe électrogène est un dispositif autonome capable de produire de l'électricité. La plupart des groupes sont constitués d'un moteur thermique qui actionne un alternateur. Leur taille et leur poids peuvent varier de quelques kilogrammes à plusieurs dizaines de tonnes. La puissance d'un groupe électrogène s'exprime en VA (voltampère), kVA (kilovoltampère) ou MVA (mégavoltampère) selon la puissance. Les unités les plus puissantes sont mues par des turbines à gaz ou de gros moteurs Diesel.
European super gridThe European super grid is a possible future super grid that would ultimately interconnect the various European countries and the regions around Europe's borders – including North Africa, Kazakhstan, and Turkey – with a high-voltage direct current (HVDC) power grid.
Load balancing (electrical power)Load balancing, load matching, or daily peak demand reserve refers to the use of various techniques by electrical power stations to store excess electrical power during low demand periods for release as demand rises. The aim is for the power supply system to have a load factor of 1. Grid energy storage stores electricity within the transmission grid beyond the customer.
Thin-film lithium-ion batteryThe thin film lithium-ion battery is a form of solid-state battery. Its development is motivated by the prospect of combining the advantages of solid-state batteries with the advantages of thin-film manufacturing processes. Thin-film construction could lead to improvements in specific energy, energy density, and power density on top of the gains from using a solid electrolyte. It allows for flexible cells only a few microns thick. It may also reduce manufacturing costs from scalable roll-to-roll processing and even allow for the use of cheap materials.
Diesel multiple unitA diesel multiple unit or DMU is a multiple-unit train powered by on-board diesel engines. A DMU requires no separate locomotive, as the engines are incorporated into one or more of the carriages. Diesel-powered single-unit railcars are also generally classed as DMUs. Diesel-powered units may be further classified by their transmission type: diesel–mechanical DMMU, diesel–hydraulic DHMU, or diesel–electric DEMU. The diesel engine may be located above the frame in an engine bay or under the floor.
Environmental impact of wind powerThe environmental impact of electricity generation from wind power is minor when compared to that of fossil fuel power. Wind turbines have some of the lowest global warming potential per unit of electricity generated: far less greenhouse gas is emitted than for the average unit of electricity, so wind power helps limit climate change. Wind power consumes no fuel, and emits no air pollution, unlike fossil fuel power sources. The energy consumed to manufacture and transport the materials used to build a wind power plant is equal to the new energy produced by the plant within a few months.
