The 2000-watt society is an environmental vision, first introduced in 1998 by the Swiss Federal Institute of Technology in Zurich (ETH Zurich), which pictures the average first world of 2000 watts (ie 2 kilowatt-hours per hour or 48 kWh per day) by the 2050 year, without lowering their standard of living. The concept is not only personal or household energy use, but the total for the whole society, including the embodied energy, divided by the population. Two thousand watts is about the current world average rate of total primary 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 considered that the use of carbon-based fuels would be less than 500 watts per person within 50 to 100 years. The vision was developed in response to climate change, energy security, and the future availability of energy supplies.

Breakdown of average energy consumption of 5.1 kW by Swiss person as of July 2008:
Researchers in Switzerland believe that this vision is achievable, despite having projected 65% increase in economic growth by 2050, by using new low-carbon technologies and techniques. It is envisaged that achieving the goal of a 2000-watt society will require, among other measures, a complete reinvestment in the country’s capital assets; refurbishment of the nation’s building stock to bring it up to low-energy building standards; significant improvements in the efficiency of road transport, aviation and energy-intensive material use; the possible introduction of high-speed maglev trains; renewable energy sources, district heating, microgeneration and related technologies; and a refocusing of research into new priority areas. As a result of the intensive research and development effort required, it is hoped that Switzerland will become a leader in the technologies involved. Indeed, the idea has a great deal of government backing, due to fears about climate change.
Launched in 2001 and located in the metropolitan area of Basel, Pilot Region Basel aims to develop and commercialize some of the technologies involved. The pilot is a partnership between industry, universities, research institutes and the authorities, coordinated by Novatlantis. Participation is not restricted to locally based organizations. The city of Zurich joined the project in 2005 and the canton of Geneva, declared in its interest in 2008. Within the pilot region, the projects in progress gas, hydrogen and biogas. The aim is to put research into practice, seeking continuous improvements, and the public.
The “smart living lab”, based in Friborg, reunites researches from the School of Engineering and Architecture of Friborg, the Freiburg University and the Swiss Federal Institute of Technology (EPFL). Together, they design the smart living building, which will be both a sustainable structure and an evolving building and its erection is to take place in 2020. It will house the activities of some 100 researchers, offering laboratories, offices, conference rooms and some experimental dwellings. In this multiple-use context, the building will become an experimental field of studies in itself, and aims to find solutions to energy consumption and the greenhouse gas emissions that it generics. This construction is the group’s first case study, and research projects have been established to meet the objectives of the 2000-watt society vision, while considering the whole life cycle of its components. These goals are to be met by 2021, that is, almost 30 years ahead of the 2000-watt-society vision’s deadline.
