Energy efficiency guru Amory Lovins: ‘It’s the largest, cheapest, safest, cleanest way to address the crisis’

One of the leading advocates of energy conservation explains why this could be a turning point for climate economics

Temperatures dropped far below freezing this week in Snowmass, Colorado. But Amory Lovins, who lives high up in the mountains at 7,200ft above sea level, did not even turn on the heating.

That's because he has no heating to turn on. His home, a great adobe and glass mountainside eyrie that he designed in the 1980s, collects solar energy and is so well insulated that he grows and harvests bananas and many other tropical fruits there without burning gas, oil or wood.
