Sustainable living Lester R. Brown, a prominent environmentalist and founder of the Worldwatch Institute and Earth Policy Institute, describes sustainable living in the twenty-first century as "shifting to a renewable energyâ€“based, reuse/recycle economy with a diversified transport system."[6] In addition to this philosophy, practical eco-village builders like Living Villages maintain that the shift to renewable technologies will only be successful if the resultant built environment is attractive to a local culture and can be maintained and adapted as necessary over the generations.
