Beak Truth to Power

Scientists question ivory-billed woodpecker evidence Conservationists and bird lovers have been enjoying their euphoric high from the rediscovery of the legendary, turns-out-not-extinct-after-all ivory-billed woodpecker. So leave it to a trio of meddling scientists to come along and harsh the buzz. Three biologists have written a paper questioning whether the evidence gathered to support the alleged […]

Between the Devil and the Deep Green Supercenter

Wal-Mart building two experimental green stores Mega-giganto retailer Wal-Mart is conducting an experiment. No, not the world-domination experiment, a different one: It’s constructing two “Supercenters” with green-building features designed to reduce energy and water use. The first, in Texas, will have solar cells embedded in skylights; runoff waste water will be captured and reused; heat […]

Denver U. law students work on green case against feds.

Did you know this?

Thirteen years ago ... Congress passed a law mandating that, by 1999, 75 percent of the federal fleet of light-duty vehicles (excepting emergency and tactical vehicles) be capable of running on alternative fuels rather than on gasoline. State governments were given until 2001 to meet the same mandate.

It's true.The law in question is Public Law 102-486, otherwise known as the Energy Policy Act of 1992. The bill begins with a bang:

Google expands its borders

Google Earth has been out for a while now, so I hesitate to post on it, since anyone who thinks it's a cool idea has probably already heard about it. But it hasn't been mentioned here yet, and this little treat today (make sure you zoom all the way in) seemed occasion enough.

People have also been using the software to look at large-scale impacts humans have had and continue to have on the environment, a la the UN atlas, only more interactive.

Wilson weighs in; corn withers

Kelpie Wilson, environmental editor of truthout.org, writes today on the possibility of corn as fuel. Fuhgeddaboutit, is the short answer.

Citing the Patzek/Pimentel paper mentioned in the lively comments section of biodiversivist's "Bad idea" post, Wilson notes that the current energy bill (great resource on that here) is going to have some interesting results if it's passed -- it will both encourage ethanol production and demand that less fossil fuels be used.

But increased ethanol production will actually lead to an increase in the amount of fossil fuels used: "We would use less fossil fuel and produce less greenhouse gas by burning the fossil fuel directly in the motor vehicle." Yet another reason to take a pass on this year's energy bill as the LA Times editorial board suggests.

Wilson actually concludes that we might be better off using corn for cars, because this would mean less high-fructose corn syrup, which she asserts has an even worse effect than the biofuel. However, it's clear that biofuel is not going to be a feasible solution for the global car fleet, even if demand is significantly reduced. There is certainly low-hanging fruit to be grabbed, but biofuel is going to remain a niche market.

Holmstead resigns

The Offal Truth

Promising clean-energy company may have to leave U.S. to succeed Certain folks take it as quasi-religious doctrine that strong green regulation is bad for economic growth. Tell it to Philadelphia’s Changing World Technologies, a burgeoning clean-energy company that may have to leave the U.S. precisely because of lax environmental laws. Every day, CWT turns 270 […]

Urbana Renewal

Illinois commission votes to expand state’s clean energy sources The Illinois Commerce Commission has approved a sustainable-energy initiative designed to increase the state’s reliance on renewables, especially wind power. The plan is voluntary, but if it is fully embraced by all of the state’s utilities Illinois could see 8 percent of its electricity produced via […]

Brussels Pouts

European Union commissioners duke it out over green legislation Today’s meeting of the E.U.’s European Commission is a make-or-break moment for the union’s sustainable-development policies, according to eco-advocates. Since taking office last November, commission president José Manuel Barroso has delayed initiatives on pesticides, the marine environment, air quality, and more, saying they might prevent the […]
