Deep thoughts

On the International Conference on Climate Change

If only Congress would have signed on to the Manhattan Declaration years ago, we could have spent valuable resources wisely summarizing nonexistent reports, thereby avoiding the subprime crisis.

This just in: Hydrogen fuel cell cars are still dead

Years after everyone else, GM and Toyota execs skeptical about hydrogen cars

That Saturday Night Live-esque headline was inspired by a story in The Wall Street Journal yesterday: Top executives from General Motors Corp. and Toyota Motor Corp. Tuesday expressed doubts about the viability of hydrogen fuel cells for mass-market production in the near term and suggested their companies are now betting that electric cars will prove to be a better way to reduce fuel consumption and cut tailpipe emissions on a large scale. Really? Hydrogen cars of dubious viability? Who ever could have guessed that in a million years? And electric cars are "a better way to reduce fuel consumption and cut tailpipe emissions on a large scale"? I'm shocked, shocked that anyone could come to that conclusion.

The fixed vs. the negotiable

Rising electricity demand is a choice, not an inevitability

Discussions of public policy frequently take place inside frames that are difficult to discern clearly without effort. Which goals are fixed and which are negotiable? Which changes are acceptable and which are not? Take, oh, homelessness. The brute fact is that we could solve homelessness in the U.S. tomorrow if we so chose. We could house and feed every homeless person for the rest of their life. It would be expensive, but not that expensive, relative to what we spend on, say, defense, or Medicare, or Social Security. We are, after all, an extraordinarily wealthy country. I’m not recommending that …

Canadian federal court ruling could halt planned oil-sands project

A Canadian federal court has ruled in favor of environmental groups that sued in opposition to a massive planned oil-sands mine in Alberta. The 120-square-mile strip mine had recently been approved by a joint federal-provincial panel that found the project’s estimated annual greenhouse-gas emissions of 3.7 million tons to be insignificant. Yet no justification was given for the finding. “The panel dismissed as insignificant the greenhouse-gas emissions without any rationale,” the judge wrote, ruling that the panel must justify its conclusion. Environmentalists hoped the ruling would force stricter reviews of similar projects in the future. If it’s ultimately approved, the …

Here comes the sun -- again

Solar thermal plants make a comeback

Photo: nrel.gov As part of the Back to the Future alternative energy series, The New York Times has an article today about the rising demand for solar thermal power plants, which use solar panels to heat water and operate a steam turbine. Among the advantages cited: On sunny afternoons, those 10 plants would produce as much electricity as three nuclear reactors, but they can be built in as little as two years, compared with a decade or longer for a nuclear plant. Some of the new plants will feature systems that allow them to store heat and generate electricity for hours after sunset. In addition, solar thermal can provide energy more reliably than wind can, and it provides the most energy during mid-day, when energy usage peaks.
