The 2000-watt society (2,000-Watt Society) is an environmental vision, first introduced in 1998 by the Swiss Federal Institute of Technology in Zürich, which pictures the average First World citizen reducing their overall average continuous energy usage to no more than 2,000 watts (48 kilowatt-hours per day) by the year 2050 - without lowering their standard of living. The concept addresses not only personal or household energy use, but the total for the whole society, divided by the population. Two thousand watts is approximately the current world average rate of total energy use. This compares to averages of around 6,000 watts in western Europe, 12,000 watts in the United States,〔()〕 1,500 watts in China, 1,000 watts in India, 500 watts in South Africa and only 300 watts in Bangladesh. Switzerland itself, currently using an average of around 5,000 watts, was last a 2000-watt society in the 1960s. It is further envisaged that the use of carbon based fuels would be ultimately cut to no more than 500 watts per person within 50 to 100 years. The vision was developed in response to concerns about climate change, energy security, and the future availability of energy supplies. It is supported by the Swiss Federal Office of Energy,〔(【引用サイトリンク】title=Federal government energy research )〕 the Association of Swiss Architects and Engineers, and other bodies. ==Current energy use== Breakdown of average energy consumption of 5.1 kW by a Swiss person as of July 2008: *1500 watts for living and office space (this includes heat and hot water) *1100 watts for food and consumer discretionary (including transportation of these to the point of sale) *600 watts for electricity *500 watts for automobile travel *250 watts for air travel *150 watts for public transportation *900 watts for public infrastructure 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「2000-watt society」の詳細全文を読む スポンサード リンク
