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.

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.

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.

Facts are more mundane than fantasies, but a better basis for conclusions.

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.

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.
