Crystalline siliconCrystalline silicon or (c-Si) Is the crystalline forms of silicon, either polycrystalline silicon (poly-Si, consisting of small crystals), or monocrystalline silicon (mono-Si, a continuous crystal). Crystalline silicon is the dominant semiconducting material used in photovoltaic technology for the production of solar cells. These cells are assembled into solar panels as part of a photovoltaic system to generate solar power from sunlight. In electronics, crystalline silicon is typically the monocrystalline form of silicon, and is used for producing microchips.
Panneau photovoltaïque thermiqueUn panneau photovoltaïque thermique (PV-T), ou panneau solaire hybride, ou encore panneau aérovoltaïque est un dispositif conçu à la fois pour produire de l'électricité photovoltaïque et pour recueillir l'énergie thermique provenant du Soleil.
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.
Récolte d'énergieLa récolte d'énergie (energy harvesting ou energy scavenging en anglais) est le processus par lequel de l'énergie est tirée de sources externes (solaire, éolienne, thermique, vibratoire, cinétique, chimique, etc.) en quantités infinitésimales, puis emmagasinée pour servir au fonctionnement autonome d'appareils portables de petite taille comme ceux de l'électronique vestimentaire (wearable electronics en anglais), les réseaux de capteurs sans fil mais aussi des applications de grande taille, notamment pour les sources thermiques: fonderies, spatial (générateur thermoélectrique à radioisotope), etc.
100% renewable energy100% renewable energy means getting all energy from renewable resources. The endeavor to use 100% renewable energy for electricity, heating, cooling and transport is motivated by climate change, pollution and other environmental issues, as well as economic and energy security concerns. Shifting the total global primary energy supply to renewable sources requires a transition of the energy system, since most of today's energy is derived from non-renewable fossil fuels.
Embedded emissionsOne way of attributing greenhouse gas (GHG) emissions is to measure the embedded emissions of goods that are being consumed (also referred to as "embodied emissions", "embodied carbon emissions", or "embodied carbon"). This is different from the question of to what extent the policies of one country to reduce emissions affect emissions in other countries (the "spillover effect" and "carbon leakage" of an emissions reduction policy). The UNFCCC measures emissions according to production, rather than consumption.
Solar powerSolar power is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Photovoltaic cells convert light into an electric current using the photovoltaic effect. Concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight to a hot spot, often to drive a steam turbine.
Rooftop solar powerA rooftop solar power system, or rooftop PV system, is a photovoltaic (PV) system that has its electricity-generating solar panels mounted on the rooftop of a residential or commercial building or structure. The various components of such a system include photovoltaic modules, mounting systems, cables, solar inverters and other electrical accessories. Rooftop mounted systems are small compared to utility-scale solar ground-mounted photovoltaic power stations with capacities in the megawatt range, hence being a form of distributed generation.
Compensation carboneLa compensation carbone consiste à essayer de contrebalancer ses propres émissions de par le financement de projets de réduction d'autres émissions ou de séquestration de carbone. Elle est présentée comme étant l'un des outils disponibles pour atteindre la neutralité carbone dans le cadre de l'atténuation du réchauffement climatique. Elle s'applique essentiellement au , mais peut s'appliquer également aux émissions d'autres gaz à effet de serre (GES).
Solar air heatSolar air heating is a solar thermal technology in which the energy from the sun, insolation, is captured by an absorbing medium and used to heat air. Solar air heating is a renewable energy heating technology used to heat or condition air for buildings or process heat applications. It is typically the most cost-effective out of all the solar technologies, especially in commercial and industrial applications, and it addresses the largest usage of building energy in heating climates, which is space heating and industrial process heating.
