Boo, Yorker

On David Owen and William Jevons

David Owen's latest piece in The New Yorker has attracted much attention and rekindled interest in William Jevons and his paradox, and much ink has been spilled in support of and opposition to the article. Amidst the discussion, I'm struck that two rather obvious points haven't been made: Jevons' arguments wouldn't pass muster in any discipline other than economics, and Owen's arguments fail basic principles of logic.

Lies, damned lies, and natural gas price forecasts

Shale gas doesn't change everything

The new natural gas conventional wisdom says that "shale changes everything." Access to these large volumes of relatively low-cost gas will raise U.S. natural gas prices and decrease price volatility. That's why prices are low now, and why they'll stay there in the future. Trouble is, the narrative really doesn't hold water. Maybe gas prices will stay low in the future, maybe they won't. But whichever the case, it won't be because of shale.

District energy 101

Why 'clean coal' will never, ever matter

Carbon capture and sequestration, the great hope of the coal industry, makes no economic sense under any scenario in which there's a price on carbon pollution. Here's why.

It's the electricity, stupid

As energy use goes, so goes the economy

Economic activity tends to track energy use. In particular, demand for electricity is a reliable predictor of economic growth. Recent trends in electricity demand portend bad news for the economy (and the Democrats).

Clean energy: It’s not about the technology

Suppose two factories produce and sell identical widgets at $1 each. Now, suppose a law is passed to provide one of those factories with $9 of additional revenue per widget. Clearly, this is law will …

Remember when we called this stuff "cheap"?

Coal-fired power was the big loser in the economic downturn

There’s some interesting new data out on recent shifts in electricity demand and consumption, courtesy of the DOE/EIA. In 2008, total U.S. power generation was 4.1 million GWh. In 2009, that fell by 4 percent, …
