The neverending debate on corn ethanol continues

This is my response to Brooke Coleman's response to, uh, this response ...

Welcome back, Brooke.

I do think ethanol is better than oil ...

Hundreds of millions of Americans do not "think" that the theory of evolution is valid. What you or I want to believe is largely irrelevant. The arguments we bring to the table to back up what we "think" is what matters. The following graphic is an attempt to explain a concept called leakage -- the fatal flaw in any attempt to divert food crops to gas tanks:

Why ecology explains growth, and economists don’t

Recently there have been a number of discussions concerning economic growth and global warming. Some have argued that the effort to prevent as much global warming as possible will incur unacceptable costs to the global economy in terms of growth. Others have argued that growth is causing global warming.

I want to argue that neoclassical economics is badly designed to help with this debate. The two main problems, in my opinion, are that economics does not see the economy as being composed of a set of nonsubstitutable "life support" functions, to use Joshua Farley's phrase; and the neoclassical theory of economic growth is inadequate (PDF) for understanding how global warming (and most everything else) will effect growth.

The problem of economic growth looms large in both the DICE model put forward by William Nordhaus, and the Stern Report, led Sir Nicholas Stern, because they both calculate the extent to which global warming and global warming mitigation will effect growth. In 1991, Stern opined that growth theory "has, however, been a popular topic for those involved in formal economic theory only for short periods, notably from the mid 1950s to the late 1960s." There is a good reason for this: neoclassical growth theory doesn't really explain economic growth.

A great summary of recent studies on green jobs

Clean energy, a job-creation engine already generating impressive performance, will rev up to even higher levels in coming years. A comprehensive new fact sheet (PDF) from the Environmental and Energy Study Institute strongly documents these trends with capsule summaries of dozens of recent studies on the topic.

In the last several years, numerous studies have validated the emergence of renewable energy and energy efficiency as a major new economic and employment driver. EESI -- a Washington, D.C.-based think tank that educates Capitol Hill on energy issues and the general public on energy legislation -- has created this invaluable fact sheet to survey many of the major national, state, and industry studies. Here are a few samples:

Tips for low-carbon merrymaking

See that green line on the map? Study it closely, boozehounds. Those of you to the right of it can enjoy a nice French Bordeaux. Those to the left should be getting your Pinot from Napa.

So concludes Dr. Vino in his excellent -- and topical! -- study, "Red, White and 'Green': The Cost of Carbon in the Global Wine Trade."

The paper is nicely readable in addition to being thorough. Few details go unconsidered. Dr. Vino cares about the CO2 produced from the breakdown of sugar during the fermentation process. He mulls the land-use implications of grape production. He knows his screw caps from his corks.

All of these factors (well, not the corks) feed into a model that allows the paper's authors to compute the carbon content of different bottles of wine drunk in various points in the U.S. Some conclusions:

Hybrid emissions: Facts and numbers

Having laid out my views in part I, let me turn to the actual data regarding hybrids -- both from an environmental and economic perspective.

How do carbon emissions per mile driven compare for various cars? The Volt is expected to be "less than $30,000" with a 1.0L engine. Compare this to the Corolla, with a 1.8Lengine (peak hp of 126; 31 mpg) and a price of $14,400. It's worth noting that this is in the optimistic, no-gasoline-use scenario for the Volt, computed below along with carbon emissions for the Volt running on cellulosic ethanol and gasoline, and emissions for comparable-sized ICE cars. Questions on the Volt's actual usage patterns remain: how many people will recharge everyday? What percentage of total miles will be on the grid, and what percentage on gasoline?
