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.
Biomass to liquidBiomass to liquid (BtL or BMtL) is a multi-step process of producing synthetic hydrocarbon fuels made from biomass via a thermochemical route. According to a study done by the U.S. Department of Agriculture and the Department of Energy, the United States can produce at least 1.3 billion tons of cellulosic biomass each year without decreasing the amount of biomass needed for food, animal feed, or exports. The Fischer–Tropsch process is used to produce synfuels from gasified biomass.
Culture énergétiquevignette|upright=1.5|Plantation dans le cadre du programme de cultures énergétiques du département de l'Environnement, de l'Alimentation et des Affaires rurales (DEFRA) au Royaume-Uni. Une culture énergétique est une espèce végétale cultivée pour produire de la biomasse destinée à une valorisation énergétique, afin de produire de l'électricité ou de la chaleur. Ces plantes peuvent être ligneuses ou herbacées, ces dernières étant souvent des graminées (famille des Poaceae).
