Home energy storageHome energy storage devices store electricity locally, for later consumption. Electrochemical energy storage products, also known as "Battery Energy Storage System" (or "BESS" for short), at their heart are rechargeable batteries, typically based on lithium-ion or lead-acid controlled by computer with intelligent software to handle charging and discharging cycles. Companies are also developing smaller flow battery technology for home use.
Energy systemAn energy system is a system primarily designed to supply energy-services to end-users. The intent behind energy systems is to minimise energy losses to a negligible level, as well as to ensure the efficient use of energy. The IPCC Fifth Assessment Report defines an energy system as "all components related to the production, conversion, delivery, and use of energy". The first two definitions allow for demand-side measures, including daylighting, retrofitted building insulation, and passive solar building design, as well as socio-economic factors, such as aspects of energy demand management and remote work, while the third does not.
Energy marketEnergy market is a type of commodity market that deal with electricity, heat, and fuel products. Major commodities being natural gas and electricity. Other commodities traded in the energy market are: oil, coal, carbon emissions (greenhouse gases), nuclear power, solar energy, and wind energy. Due to the difficulty in storing and transporting energy, current and future prices in energy are rarely linked. This is because energy purchased at current prices is difficult to store and sell at a later date.
Château d'eauUn château d'eau est une construction destinée à stocker l'eau potable, elle est placée en général sur un sommet géographique pour permettre de la distribuer sous pression. La réserve d'eau joue un rôle de tampon entre le débit demandé par les abonnés et le débit fourni par la station de pompage. Il permet ainsi d'éviter de démarrer trop souvent les pompes et de les protéger. Une telle réserve permet également de faire face aux demandes exceptionnelles en cas d'incendie et de manque d'eau.
