Adjustable rate mileage

Your fuel mileage is lower than you think.

Granted, that assumes you do not fastidiously monitor your own fuel mileage -- that instead you take the EPA's fuel mileage estimates at their word.

Turns out, the EPA calculates fuel economy with "straight" (100 percent) gasoline. However, in the consumer market a blend of 10 percent ethanol, E10, is nearly universal. Jonathan Welsh of The Wall Street Journal explains:

Fuel economy decreases by about 2% for vehicles running on E10, so a car rated at 25 miles per gallon will actually travel about 24.5 miles.

Okay, this decrease is peanuts if you're a lead-foot. And the EPA just started including air conditioning with this year's estimates. Nevertheless, even with perfect driving habits, the fuel economy of your brand new Prius will never match the sticker's claims.

The media’s central arguments for and against Gore’s challenge to the nation

Nearly a week after Gore unveiled his carbon-free challenge (sounds sadly kind of like a reality TV gimmick), the substantive reactions from the nation's editorial pages and blogosphere fit (for better of for worse) into two groupings: precedent versus vision.

Brushing past the naysayers (John Tierney and his "junk science" complaints) and the yes-men (Christine Pelosi and her Gorish platitudes), those in the "precedent" camp tend to disapprove of Gore's goal on the basis that United States continues to produce very little renewable energy, so these critics say ramping up to 100 percent renewable is impossible. Those in the "vision" group tend to applaud Gore's call on the basis that it offers a compelling vision for the future, even if it lacks details.

These divisions do not completely break down along political lines. It's true that those who tend not to like Al Gore tend not to like Al Gore's challenge and vice versa; yet, there are some notable exceptions.

Can the coal industry and an environmental blog find common ground?

In response to this post on the many varied reactions to Gore's energy speech, Behind the Plug (the coal industry blog for which we have strong language) contacted me regarding questions for Gore on "Meet the Press." The impetus: Coming from very distant sides of political and editorial spheres, could we find some common ground to collaborate on a question for Gore?

As Behind the Plug says in its post, "We all breathe the same air and we all have an interest in America's energy future." Thus, based on the blogosphere roundups and reader comments -- and without feigning scientific expertise -- the joint question that both of us would like to see answered:

Bloggers weigh Gore’s plan in advance of ‘Meet the Press’

Liberals love Gore's gall. Conservatives hate that he drove a gas-guzzler to the big speech. Politicians grumble over his timing. Climate policy wonks and science geeks admire the inititive, but want something a little more ... feasible ... say, 50 to 90 percent renewable electricity by 2020 with a little natural gas for good measure?

Across the blogosphere, however, certain questions about Gore's plan remain unanswered. What practical measures will we take to get to zero emission electricity in 10 years? Who will lead the charge? From where will the requisite funds come to finance this energy operation? Will Tom Brokaw grill Gore on "Meet the Press" this Sunday? Or will the Goracle leave the details to those in the political trenches and dodge the pragmatic bullet?
