The US and Australia consume the most energy per person. But this could be slashed by 90%, while still guaranteeing decent living standards for all.
Energy requirements could likely come from clean, renewable sources. Achieving such a world requires radical action on all fronts, including the mass rollout of the best technologies available: the most energy-efficient buildings, vehicles, appliances and lighting systems, along with the most advanced facilities to produce and recycle all the necessary materials.
It also requires drastically reducing energy and resources people consume. There’s no longer room for second homes or cars, 20 minute power showers, biannual upgrades of electronic gadgets, new shoes every season, or plates piled high with red meat seven nights a week.
We’d need to rein in the excessive consumption levels of the affluent to raise the living conditions of the 3.5 billion people living on less than six dollars a day.
