“Renewable energy” has two fundamental conceptual flaws. It’s not really renewable, and it’s not really energy.
What is “Renewable”?
“Renewable” in most definitions approximates to something like “naturally replenished” and it often contrasted with allegedly inferior, “finite” sources. It brings to mind the image of a pizza where a slice, once eaten, magically reappears.
There is no such phenomenon in nature, though. Everything is finite. The sun and the photons and wind currents it generates are not infinite; they are just all part of a very large nuclear fusion reaction. True, that nuclear fusion reaction will last billions of years, but so will the staggering amounts of untapped energy stored in every atom of our “finite” planet.
To obsess about whether a given potential energy source will last hundreds of years or billions of years is to neglect the key issue that matters to human life here and now: whether it can actually provide the usable energy that will maximize the quantity and quality of human life.…

Let’s start keeping track of them now, and when the famines come, let’s make them pay. Let’s let their houses burn. Let’s swap their safe land for submerged islands. Let’s force them to bear the cost of rising food prices…. They broke the climate.”
– Steve Zwick, Forbes, April 19, 2012.
As Chip Knappenberger chronicled earlier this week, there are a number of positive developments in climate science that contradict the doomism and negativity of many climate campaigners. There are benefits, not only costs, to greater carbon dioxide (CO2) concentrations in the atmosphere.
And so it came as a shock, a chill, to read the above quotation from Steve Zwick, the editor of the Ecosystem Marketplace and a contributor (as I am) to Forbes online.…

I was one of nine witnesses testifying. In addition to myself, the let-the-market-decide witnesses were Dr. Benjamin Zycher, Visiting Scholar, American Enterprise Institute, Tax and Other Subsidies for Renewable Energy Should Be Abandoned; and Margo Thorning, Senior Vice President and Chief Economist, American Council for Capital Formation (testimony here).
The subcommittee Republicans were prepared, well informed, and interested in drawing out the facts. The Democrats, on the defensive, complained that the hearing was happening, argued the subcommittees lacked the jurisdiction to hold the hearing, and claimed that renewables were being short-changed compared to oil and gas.
A summary of my testimony (full version here) follows:
Background and Purpose
Energy policy in the United States calls for the aggressive deployment of renewable generation which has led to an explosion of expensive renewable resources that are variable, operating largely off-peak, off-season and are located in rural areas with limited transmission.…
