ECONOMICS OF BIOFUELSeconomics_biofuels

Aside from rejecting biofuel expansion and use for environmental reasons (see Biofuels (Land and Water Concerns)[] and Biofuels (Miscellaneous)[] in our Subject Index), the production and use of biofuels from an economic perspective does not make much sense either. Proponents of biofuels say their increased production will increase the supply of transportation fuels and therefore lead to lower prices. Critics of biofuels point out ethanol often costs more, not less, than gasoline, either because of production costs or supplies that can’t keep pace with government mandates, and therefore leads to higher prices at least in the short run.

 

Analysis of the 2nd Order Draft of the Working Group I IPCC 5AR

The preparation of IPCC Assessment Reports involves several stages, three of which are designated
“Expert Review”, “Expert and Government Review” and “Government Review”. These three stages
respectively address the first order draft (FOD), the second order draft (SOD) and the near-final
draft of the Summary for Policymakers.

Of particular interest to the wider scientific community is the review of the SOD of the Working
Group I contribution to these assessment reports because this is the last stage at which individual
reviewers can comment on the draft document.

In 2006, when I first made the mistake of writing publicly of my doubts about the Party Line on manmade global warming, I began to receive 100 emails a day from interested members of the public ? and of the scientific community. I have been doing my best to answer the best of them ever since.

 

One was from Dr. Dennis Ray Wingo of NASA. He told me the magnetic convection currents beneath both hemispheres of the Sun had slowed to walking pace. This was unprecedented in the record. He expected that solar cycles would lengthen and the vigor of solar activity would decline, perhaps for up to 60 years.
