In order to save the planet from catastrophic climate change, Americans will have to cut their energy use by more than 90 percent and families of four should live in housing no larger than 640 square feet. That's at least according to a team of European researchers led by University of Leeds sustainability researcher Jefim Vogel. In their new study, "Socio-economic conditions for satisfying human needs at low energy use," in Global Environmental Change, they calculate that public transportation should account for most travel. Travel should, in any case, be limited to between 3,000 to 10,000 miles per person annually.
Vogel and his colleagues set themselves the goal of figuring out how to "provide sufficient need satisfaction at much lower, ecologically sustainable levels of energy use." Referencing earlier sustainability studies they argue that human needs are sufficiently satisfied when each person has access to the energy equivalent of 7,500 kilowatt-hours (kWh) of electricity per capita. That is about how much energy the average Bolivian uses. Currently, Americans use about 80,000 kWh annually per capita. With respect to transportation and physical mobility, the average person would be limited to using the energy equivalent of 16–40 gallons of gasoline per year. People are assumed to take one short- to medium-haul airplane trip every three years or so.

Developing a high-energy planet will spur economic growth and innovation, helping to provide for all of the human needs that concern Vogel and his colleagues. Instead of trying to force Americans to live on the amount of energy currently available to Bolivians, the goal should be to enable people in energy-starved poor countries to gain access to energy supplies currently enjoyed by average Americans.
