How smart climate policy can cut our energy costs

True confessions: I love weatherstripping. And programmable thermostats. And insulation -- all kinds. Oh, and efficient shower heads with "Navy shower" shut-off valves. And high-efficiency appliances. And waste-water heat recovery systems. You get the idea: I actually enjoy the process of making buildings more energy wise -- enjoy as in, "Yippee, it's Saturday! Where's my caulk gun?" So today's topic is especially near to my heart: the role in climate policy of low-income weatherization programs and related efficiency upgrades for working families.

A quick review: climate change is economically unfair by nature; it punishes those least to blame. Auctioned cap-and-trade can counteract this injustice. I've already written about two ways to seize this opportunity: distribute the money from the auction of carbon allowances as equal dividend checks to every citizen ("cap-and-share"), or make sure dividends get to low-income families who are hardest hit by rising energy prices ("cap-and-buffer").

A third option is to invest auction proceeds in energy efficiency in ways that specially benefit working families, by weatherizing homes, for example, or improving the efficiency of household appliances. (Let's call it "cap-and-caulk.")

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:

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:

The U.S. sits on the sidelines rather than leading the charge in a war on climate change

Americans have a history of joining together in times of crisis. But the terminology of war is the most familiar rallying cry.

So it's understandable that when he's talking about global warming, John Edwards often implores Americans to be "patriotic about something other than war." And when Al Gore accepted his Nobel Prize this week, he said, "We must quickly mobilize our civilization with the urgency and resolve that has previously been seen only when nations mobilized for war."

So, where is America the strong, free, brave, visionary? Where is America, defender of the world's climate?

The U.S. is not leading the charge at this week's U.N. climate conference in Bali. American delegates have insisted they would not be a "roadblock" to a new international agreement aimed at reducing greenhouse gases. Not be a roadblock? Was it irony or simply poor word choice?

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:
