Fire made us human, fossil fuels made us modern, but now we need a new fire that makes us safe, secure, healthy and durable.

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

We've got 21st century technology and speed colliding head-on with 20th and 19th century institutions, rules and cultures.

Nature does not compromise; a pelican is not a compromise between a crow and otter, it is just a pelican. Nature makes no compromises; any inefficient products are recalled to the manufacturer!

Energy-saving technologies keep improving faster than they're applied, so efficiency is an ever larger and cheaper resource.

I'm a practitioner of elegant frugality. I don't feel comfortable telling other people what to do, so I just try and lead by example.

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.

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.

Economies are supposed to serve human ends.. not the other way round. We forget at our peril that markets make a good servant, a bad master and a worse religion.

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.

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.

When you're finally a grown-up, one of the things you find is that there are no grown-ups.

I don't really see the hurdles. I sense them like a memory.

Most men expose themselves in battle enough to save their honor, few wish to do so more than sufficiently, or than is necessary to make the design for which they expose themselves succeed.

A wise man, recognizing that the world is but an illusion, does not act as if it is real, so he escapes the suffering.

There are flaws in romance but love is perfect.

A hot wind was blowing around my head, the strands of my hair lifting and swirling in it, like ink spilled in water.

My body may have been abused, but it certainly hasn't been neglected.

No joy can equal the joy of serving others.

It is impossible for capitalists and laborers to have common interests.

In my mind, I'm always the best. If I walk out on the court (and) I think the next person is better, I've already lost.
