A conversation with energy guru Amory Lovins

This covers a variety of issues, e.g., Big Coal, liquid coal,
biofuels, etc.  Here is an excerpt:

So I would not pay too much attention to what Congress is doing. I'm not saying it doesn't matter, but ultimately economic fundamentals govern what will happen -- things that don't make sense, that don't make money, cannot attract investment capital.

We see this now in the electricity business. A fifth of the world's electricity and a quarter of the world's new electricity comes from micropower -- that is, combined heat and power (also called cogeneration) and distributed renewables. Micropower provides anywhere from a sixth to over half of all electricity in most of the industrial countries. This is not a minor activity anymore; it's well over $100 billion a year in assets. And it's essentially all private risk capital.

So in 2005, micropower added 11 times as much capacity and four times as much output as nuclear worldwide, and not a single new nuclear project on the planet is funded by private risk capital. What does this tell you? I think it tells you that nuclear, and indeed other central power stations, have associated costs and financial risks that make them unattractive to private investors. Even when our government approved new subsidies on top of the old ones in August 2005 -- roughly equal to the entire capital costs of the next-gen nuclear plants -- Standard & Poor's reaction in two reports was that it wouldn't materially improve the builders' credit ratings, because the risks private capital markets are concerned about are still there.
