By skimping on design, the owner gets costlier equipment, higher energy costs, and a less competitive and comfortable building; the tenants get lower productivity and higher rent and operating costs.

We'd find more energy in the attics of American homes (through energy conservation measures) than in all the oil buried in Alaska.

Rely on renewable energy flows that are always there whether we use them or not, such as, sun, wind and vegetation: on energy income, not depletable energy capital.

What if we could make energy do our work without working our undoing?

If you ask me, it'd be little short of disastrous for us to discover a source of clean, cheap, abundant energy because of what we would do with it.

I once met an economist who believed that everything was fungible for money, so I suggested he enclose himself in a large bell-jar with as much money as he wanted and see how long he lasted.

The barriers that renewables and efficiency face come less from our living in a capitalist market economy and more from not taking market economics seriously.
