Encyclopedia > Sustainable community energy system

A sustainable community energy system is an integrated approach to supplying a local community with its energy requirements from renewable energy or high-efficiency co-generation energy sources. The approach can be seen as a development of the distributed generation concept. Renewable energy (sources) or RES capture their energy from existing flows of energy, from on-going natural processes, such as sunshine, wind, flowing water (hydropower), biological processes such as anaerobic digestion, and geothermal heat flow. ... Cogeneration (also combined heat and power or CHP) is the use of a power station to simultaneously generate both heat and electricity. ... Distributed generation is a new trend in electric power generation. ...


Such systems are based on a combination of district heating, district cooling, plus 'electricity generation islands' that are interlinked via a private wire electricity system (largely bypassing the normal power grid to cut transmission losses and charges, as well as increasing the robustness of the system). The surplus from one generating island can therefore be used to make up the deficit at another. District heating accumulator tower and workshops on the Churchill Gardens Estate, Pimlico, London. ... Transmission towers Transmission lines in Lund, Sweden Electric power transmission, or more accurately Electrical energy transmission, is the second process in the delivery of electricity to consumers. ...


United Kingdom

In the United Kingdom the first sustainable community energy system was pioneered by Woking Borough Council, starting in 1991. The system uses traditional and a phosphoric acid fuel cell [1] co-generation plants, thermal storage, heat fired absorption cooling and photovoltaics (over 9% of the UK's small capacity), to supply both residential and non-residential customers, as well as the Council's own facilities. By end of 2005 there were over 60 generating islands in the Borough. Woking is a large town and local government district with borough status in the west of Surrey in South East England. ... A borough is an administrative division used in the Canadian province of Quebec, in some states of the United States, and formerly in New Zealand. ... A municipality or general-purpose district (compare with: special-purpose district) is an administrative local area generally composed of a clearly defined territory and commonly referring to a city, town, or village government. ... 1991 (MCMXCI) was a common year starting on Tuesday of the Gregorian calendar. ... Phosphoric acid fuel cells (PAFC) are a type of fuel cell that uses liquid phosphoric acid as an electrolyte. ... Photovoltaics is the field of electrical engineering and semiconductor physics, which is concerned with the development of and research into solar cells. ...


Despite the investment in the plant, the system delivers cheaper energy than can be supplied from the traditional 'brown energy' suppliers, helping to tackle fuel poverty. It is part of a plan to cut local carbon dioxide emissions by 60% by 2050 and by 80% by 2100. Their initiatives won the Council the Queen's Award for Enterprise in 2002 [2]. Carbon dioxide is an atmospheric gas comprised of one carbon and two oxygen atoms. ... Centuries: 20th century - 21st century - 22nd century Decades: 2000s 2010s 2020s 2030s 2040s - 2050s - 2060s 2070s 2080s 2090s 2100s Years: 2045 2046 2047 2048 2049 - 2050 - 2051 2052 2053 2054 2055 2050 will be a common year starting on Saturday. ... 2100 can refer to either: The year at the end of the 21st century. ... The Queens Award for Enterprise is an award for British companies and other organizations who excel at international trade, innovation or sustainable development. ...
