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.

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 reason the U.S. lags so badly is that we have obsolete rules that favor big over small, supply over efficiency, and incumbents over new market entrants.

If you ask me, it'd be a little short of disastrous for us to discover a source of clean, cheap, abundant energy because of what we would do with it. We ought to be looking for energy sources that are adequate for our needs, but that won't give us the excesses of concentrated energy with which we could do mischief to the earth or to each other.

A package of 35 improvements to typical industrial motor systems can save around 50% of their metered energy…with a simple payback under 16 months.

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.
