Énergie durablevignette|L'investissement mondial dans les énergies propres devrait atteindre de dollars en 2023 ; parallèlement, pour la troisième année consécutive, l'investissement dans les énergies fossiles croît à nouveau. L'utilisation d’énergie est considérée comme durable si elle répond aux besoins du présent sans compromettre les besoins des générations futures. Les définitions de l'énergie durable incluent généralement des aspects environnementaux, comme les émissions de gaz à effet de serre, et des aspects sociaux et économiques, comme la précarité énergétique.
Renewable energy commercializationRenewable energy commercialization involves the deployment of three generations of renewable energy technologies dating back more than 100 years. First-generation technologies, which are already mature and economically competitive, include biomass, hydroelectricity, geothermal power and heat. Second-generation technologies are market-ready and are being deployed at the present time; they include solar heating, photovoltaics, wind power, solar thermal power stations, and modern forms of bioenergy.
Fossil fuels lobbyThe fossil fuels lobby includes paid representatives of corporations involved in the fossil fuel industry (oil, gas, coal), as well as related industries like chemicals, plastics, aviation and other transportation. Because of their wealth and the importance of energy, transport and chemical industries to local, national and international economies, these lobbies have the capacity and money to attempt to have outsized influence governmental policy.
BiocarburantUn biocarburant est un carburant (combustible liquide ou gazeux) produit à partir de matériaux organiques non fossiles, provenant de la biomasse (c'est le sens du préfixe « bio » dans biocarburant) et qui vient en complément ou en substitution du combustible fossile. Ceux qui sont produits par la filière agricole sont désignés sous le vocable d'agrocarburant.
Biomass (energy)Biomass, in the context of energy production, is matter from recently living (but now dead) organisms which is used for bioenergy production. Examples include wood, wood residues, energy crops, agricultural residues including straw, and organic waste from industry and households. Wood and wood residues is the largest biomass energy source today. Wood can be used as a fuel directly or processed into pellet fuel or other forms of fuels. Other plants can also be used as fuel, for instance maize, switchgrass, miscanthus and bamboo.
BiométhaneLe biométhane est un gaz riche en méthane provenant de l'épuration du biogaz issu de la méthanisation. C'est la version renouvelable non fossile du gaz naturel ; une source d'énergie qui peut en Europe contribuer à l'objectif du paquet climat-énergie et à la transition énergétique, avec moins d'émissions de gaz à effet de serre (il vaut mieux brûler le méthane que le libérer dans l'air, car c'est un puissant gaz à effet de serre), dans une perspective de troisième révolution industrielle ou de développement durable.
BioenergyBioenergy is energy made or generated from biomass, which consists of recently living (but now dead) organisms, mainly plants. Types of biomass commonly used for bioenergy include wood, food crops such as corn, energy crops and waste from forests, yards, or farms. The IPCC (Intergovernmental Panel on Climate Change) defines bioenergy as a renewable form of energy. Bioenergy can either mitigate (i.e. reduce) or increase greenhouse gas emissions. There is also agreement that local environmental impacts can be problematic.
Gas flareA gas flare, alternatively known as a flare stack, flare boom, ground flare, or flare pit is a gas combustion device used in places such as petroleum refineries, chemical plants and natural gas processing plants, oil or gas extraction sites having oil wells, gas wells, offshore oil and gas rigs and landfills. In industrial plants, flare stacks are primarily used for burning off flammable gas released by safety valves during unplanned over-pressuring of plant equipment.
Mechanical biological treatmentA mechanical biological treatment (MBT) system is a type of waste processing facility that combines a sorting facility with a form of biological treatment such as composting or anaerobic digestion. MBT plants are designed to process mixed household waste as well as commercial and industrial wastes. The terms mechanical biological treatment or mechanical biological pre-treatment relate to a group of solid waste treatment systems.
Transition énergétiqueLa transition énergétique désigne à la fois l'évolution passée de la répartition des énergies consommées sur la planète (bois, hydroélectricité, charbon, pétrole, gaz naturel, nucléaire, etc.) et, pour l'avenir, l'objectif politique et technique d'une modification structurelle profonde des modes de production et de consommation de l'énergie. C'est l'un des volets de la transition écologique.
