Mr. Adams’s claim about “an awful lot of diesel, coal, and natural gas” being consumed by micropower is addressed in Part One of my response to David Bradish’s post at http://neinuclearnotes.blogspot.com/2008/06/amory-lovins-and-his-nuclear-illusion_05.html. Mr. Bradish was referring to the fuel mix of the non-biomass cogeneration that our “micropower” database combines with renewables other than big hydropower. As I stated, cogeneration does burn some coal, but not much. The mainly gas-fired cogeneration fuel mix is unknown in detail but does include some coal, chiefly in China and India (where gas is often available), and to some extent in Germany, all aided by coal subsidies. USEIA also reported that 18.7% of the U.S. cogeneration in its partial database for 2006 that burned fossil fuels was coal-fired, including culm or waste coal. However, even coal-fired cogen greatly reduces the carbon otherwise emitted by separate production of power and heat, because it displaces the separate fueled boiler(s) otherwise needed to produce the heat that cogen recovers. The resulting carbon saving is smaller than for the predominant gas-fired cogen, let alone for renewables, but is still substantial. I hope soon to receive updated cogen data casting more light on the fuel mix, and if I do, will post it to our micropower database at http://www.rmi.org/sitepages/pid256.php#E05-04.
So Amory Lovins admits that, so far as the supposed carbon savings from "micropower" are concerned, he really doesn't know what he's talking about... but he might find out soon?
As I pointed out in the past, Lovins' definition of "micropower" makes no sense and only serves to obscure the fact that Lovins is in practice essentially shilling for fossil fuels, his (perhaps earnest) claims to the contrary aside. All that's new is that Lovins is admitting he doesn't actually have the data to support his claims.
