在英国，与主要零售食品店的能源消耗相关的年度二氧化碳排放总量约为4亿吨二氧化碳(2)。超市的能源消耗和排放差异很大，可能取决于许多因素，如商店的类型和规模、商业和销售惯例以及所使用的制冷和环境控制系统。本文提供了2570零售食品商店的一个样本的能源消耗数据，从一些主要的零售食品连锁店在英国。样本涵盖了从便利店到大卖场的所有主要商店类别，包括英国净销售面积超过2.8亿的商店总数的约30%(2)。数据显示，即使在同一零售连锁店的门店内，能源强度也存在很大差异。幂律可以用来描述样本中商店的平均电能强度随销售面积的变化。若透过节能措施，将高于平均水平的店铺的电力强度降至平均水平，每年可节省约10%的能源，即840千兆瓦时，相当于每年减少35.5万吨二氧化碳排放量。本文还讨论了零售食品商店的主要能源消耗过程，并确定了节能的机会。(C) 2010 Elsevier Ltd.版权所有。
The total annual CO2 emissions associated with the energy consumption of the major retail food outlets in the UK amount to around 4.0 MtCO(2). The energy consumption and emissions from supermarkets varies widely and can depend on many factors such as the type and size of the store, business and merchandising practices and refrigeration and environmental control systems used. This paper provides energy consumption data of a sample of 2570 retail food stores from a number of major retail food chains in the UK. The sample covers all major store categories from convenience stores to hypermarkets and includes approximately 30% of the total number of stores in the UK having a net sales area more than 280 m(2). The data show a wide variability of energy intensity even within stores of the same retail chain. A power law can be used to describe the variation of the average electrical energy intensity of the stores in the sample with sales area. If the electrical intensity of the stores above the average is reduced to the average by energy conservation measures, annual energy savings of the order of 10% or 840 GWh can be achieved representing 355,000 tonnes annual reduction in CO2 emissions. The paper also discusses the major energy consuming processes in retail food stores and identifies opportunities for energy savings. (C) 2010 Elsevier Ltd. All rights reserved.
