Swing states need green manufacturing
Suppose you just became the presumptive presidential nominee of the Democratic party, and suppose you really could use some of those Midwestern swing states in order to win the general election. Suppose, further, that you have mentioned how it would be a good thing to have high-speed rail coming out of Chicago, and that "the fight for American manufacturing is the fight for America's future." And further, suppose that there is a Midwest Interstate Passenger Rail Commission that has plans in place to construct just such a network.

Well, whaddaya know, all of those things have actually happened! In fact, according to an excellent study I found called "High-speed Rail Projects in the United States," coming out of the Mineta Transportation Institute at San Jose State University, there are a whole basket full of such proposals, some further along than others, spread all over the United States -- and many plans are in swing states.
Consider the pathetic level of rail funding that the report highlights -- and transit isn't much better:

Climate change, deforestation, erosion take toll on African landscape
A new United Nations atlas depicts alarming changes to Africa’s landscape. On a continent that produces a mere 4 percent of the world’s greenhouse-gas emissions, significant landmarks are taking a hit from climate change: Lake Chad and Lake Victoria are shrinking each year, and Mt. Kilimanjaro could be snow-free by 2020. The deforestation rate in […]

How to green your kids this summer
Once more unto the beach! Photo: Tom Twigg Child-rearing may be the ultimate eco-conundrum: If you have a child, you’re adding to a population that’s already burdening the planet. And as you raise that child, you may be too tired and burdened yourself to care whether all your choices are green. On the other hand, […]

Senate Republicans block movement on two bills to spur renewable energy investment
With gas prices now averaging a record $4.04 a gallon in the United States, the Senate voted on two bills Tuesday that would have revoked tax breaks for Big Oil and extended tax credits to renewable energy. Proponents of the two measures touted them as vital for consumer relief and transition to new energy sources, […]

China …
… is heading for a wall. In the debate over climate and sustainable development, people often talk about China as though it is some sort of rapacious automaton, blindly dedicated to growing its economy no matter the cost. But while I’ve never been to China, I’m told it’s filled with intelligent people. They know how […]

The U.S. media discover how food production works without access to cheap oil
The story is legendary in peak-oil circles: Twenty years ago, the Soviet Union pulled the plug on Cuba’s cheap-energy, cheap-food era. (See Bill McKibben’s feature piece on the subject here.) No longer would the fading superpower accept the tiny island nation’s sugar as payment for crude oil. From then on, only hard currency would do. […]

Japan sets emissions-reduction goal for 2050 but not sooner
Japanese Prime Minister Yasuo Fukuda announced Monday that Japan will aim to cut greenhouse-gas emissions between 60 and 80 percent by 2050, but did not give in to strong pressure to set an emissions-reduction target for 2020. Fukuda gave a nod in the direction of a shorter-term goal, saying Japan’s emissions will likely drop 14 […]

Reflecting on his daughter’s future, a father says the green movement must diversify
The face of America is changing — is the environmental movement ready to face change too? “Kyra, do you know this is yours?” I ask, looking down at the skinny little girl with big, curly, dark brown locks. Her hair to body proportion resembles Thing One and Thing Two from Dr. Seuss’ Cat in the […]

Today’s gas consumption shows that price increases are only one part of the solution
As SUV sales plummet and gasoline use finally drops, one meme spreading around is, "Looks like people respond to price after all." The implication seems to be that any demand response other than zero proves that prices are wonderfully effective.
The problem, however, is not response is or might be zero. (I can think of few who ever claimed that.) The problem is that it takes a big price increase to produce a small response.
The current data support the conventional wisdom: 40 to 50 percent long-term elasticity, low enough to discourage us from relying on price as the main means of reducing emissions, high enough encourage us to use price as one among many means. At first glance, the raw data are even more discouraging than the conventional wisdom: Inflation adjusted gasoline prices have risen almost two-and-a-half times since 2000. Gasoline demand has dropped by slightly over 20 percent. But long-term elasticity is, by definition, a delayed response -- at least three years.
Also, if we are interested in price response as opposed to income response, we have to adjust for growth in GDP. So a rough calculation yields 45 percent long-term elasticity (with some biases that probably overstate the result). Here are two graphs, the first of raw data, the second after adjustment (click for larger versions):

Boxer op-ed argues the Climate Security Act vote was a big step forward
Environment and Public Works Committee Chair Barbara Boxer (D-Calif.) wrote an op-ed in today’s San Jose Mercury News on the failed Climate Security Act that she championed in the Senate. In it, she argues that last week’s vote was an important advancement. “[O]ur strong vote proves that we are moving in the right direction,” she […]
