The 2000-watt society (2,000-Watt Society) is a vision, originated by the Swiss Federal Institute of Technology in Zürich at the end of 1998, in which each person in the developed world would cut their over-all rate of energy use to an average of no more than 2,000 watts (i.e. 17,520 kilowatt-hours per year of all energy use, not only electrical) 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, 1500 watts in China, 1000 watts in India, 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, the Association of Swiss Architects and Engineers, and other bodies.
