A return to 1950s suburbia may be the answer to our needs in a low-energy future, writes Fran Molloy.
With crude oil now more than $US110 a barrel and the Organisation of Petroleum Exporting Countries announcing this month that it will not succumb to demands for raised production quotas, dark predictions of an imminent descent into a global energy crisis appear to be coming true.
But the permaculture co-founder David Holmgren, who has been warning of such events for decades, believes the energy crisis heralds the beginning of a low-energy future - a future that may involve a return to 1950s suburbia.
These days Holmgren is a quietly spoken farmer in his 50s, his ponytail the only hint of the radical visionary behind the frameless spectacles.
Thirty years ago Holmgren was a university student who came up with the concept of permaculture, a blindingly simple idea: why not design our living spaces so that human needs for food, water and shelter imitated natural self-sustaining ecosystems?
