Restauration rapidevignette|redresse=1|Serveuses d'un restaurant rapide à Jakarta. La restauration rapide (fast food, en anglais) est un mode de restauration dont le but est de faire gagner du temps au client en lui permettant de consommer rapidement les plats commandés ou de les emporter, et ce, pour un prix généralement moindre que dans la restauration traditionnelle. Cela a été initialement créé pour que les travailleurs puissent prendre de la nourriture plus rapidement et avoir le temps de manger pendant leur travail.
Electronic waste recyclingElectronic waste recycling, electronics recycling or e-waste recycling is the disassembly and separation of components and raw materials of waste electronics; when referring to specific types of e-waste, the terms like computer recycling or mobile phone recycling may be used. Like other waste streams, re-use, donation and repair are common sustainable ways to dispose of IT waste. Since its inception in the early 1990s, more and more devices are recycled worldwide due to increased awareness and investment.
Recyclage des pneusLe recyclage des pneus consiste à les réutiliser dans des filières de revente d'occasion et de pneus rechapés ou à en réutiliser la matière ; la valorisation des « pneus usagés non réutilisables » (PUNR) désigne la récupération et valorisation de matériaux (caoutchouc, acier), ou de molécules énergétiques (gaz, huile) ou de produits chimiques réutilisables.
Dynamic demand (electric power)Dynamic Demand is the name of a semi-passive technology to support demand response by adjusting the load demand on an electrical power grid. It is also the name of an independent not-for-profit organization in the UK supported by a charitable grant from the Esmée Fairbairn Foundation, dedicated to promoting this technology. The concept is that by monitoring the frequency of the power grid, as well as their own controls, intermittent domestic and industrial loads switch themselves on/off at optimal moments to balance the overall grid load with generation, reducing critical power mismatches.
Sortie des combustibles fossilesthumb|right|La marée noire consécutive à l'explosion de la plate-forme pétrolière Deepwater Horizon, en 2010, a répandu de barils de pétrole dans la mer. La sortie des combustibles fossiles désigne l'abandon progressif des combustibles fossiles dans tous les secteurs où ils sont utilisés : la production d'électricité, le chauffage, les transports et l'industrie.
Traction motorA traction motor is an electric motor used for propulsion of a vehicle, such as locomotives, electric or hydrogen vehicles, or electric multiple unit trains. Traction motors are used in electrically powered railway vehicles (electric multiple units) and other electric vehicles including electric milk floats, trolleybuses, elevators, roller coasters, and conveyors, as well as vehicles with electrical transmission systems (diesel-electric locomotives, electric hybrid vehicles), and battery electric vehicles.
Fast-food restaurantA fast-food restaurant, also known as a quick-service restaurant (QSR) within the industry, is a specific type of restaurant that serves fast-food cuisine and has minimal table service. The food served in fast-food restaurants is typically part of a "meat-sweet diet", offered from a limited menu, cooked in bulk in advance and kept hot, finished and packaged to order, and usually available for take away, though seating may be provided.
Développement durablevignette|Diagramme de Venn du développement durable, à l'intersection de trois préoccupations, dites « les trois piliers du développement durable ».Les descriptions des intersections partielles peuvent varier. Le développement durable (, parfois traduit par développement soutenable) est une conception du développement qui s'inscrit dans une perspective de long terme et en intégrant les contraintes environnementales et sociales à l'économie.
Law of demandIn microeconomics, the law of demand is a fundamental principle which states that there is an inverse relationship between price and quantity demanded. In other words, "conditional on all else being equal, as the price of a good increases (↑), quantity demanded will decrease (↓); conversely, as the price of a good decreases (↓), quantity demanded will increase (↑)". Alfred Marshall worded this as: "When we say that a person's demand for anything increases, we mean that he will buy more of it than he would before at the same price, and that he will buy as much of it as before at a higher price".
Demand curveIn a demand schedule, a demand curve is a graph depicting the relationship between the price of a certain commodity (the y-axis) and the quantity of that commodity that is demanded at that price (the x-axis). Demand curves can be used either for the price-quantity relationship for an individual consumer (an individual demand curve), or for all consumers in a particular market (a market demand curve). It is generally assumed that demand curves slope down, as shown in the adjacent image.
