A: The cropland area of several states

According to data released by the U.S. Department of Agriculture's National Agricultural Statistics Service (NASS), U.S. farmers planted 92.9 million acres of corn in 2007, exceeding last year's corn area by 19 percent and surpassing the USDA's earlier projection (in March) by 3 percent. To put that number into perspective, it is equal to the total arable (cropland) area of four of the nation's leading farm states: Iowa, Illinois, North Dakota and Oklahoma.

The Food and Agricultural Policy Research Institute (FAPRI) forecasts that some 2.18 billion bushels of that corn will be converted to ethanol this year. At an average expected yield of 149.1 bushels per acre, that translates into 14.6 million acres -- an area equal to the combined arable cropland of the entire northeastern United States (Delaware, Maryland, Pennsylvania, New Jersey, New York State, and New England).

The 6.9 billion gallons of ethanol thereby produced will displace, on an energy-equivalent basis (and not accounting for the energy consumed in producing the ethanol), roughly 3 percent of the nation's annual gasoline consumption.

I just thought some readers would find these numbers interesting.

Economist stuff

Two short articles of interest in The Economist. One describes the nascent attempts to conceive and build a network of high-voltage DC power lines across Europe, which would enable wind and solar to play the role of baseload power. The other is about compressed-air storage. This is nifty, but confusing: Meanwhile, General Compression, a small […]

Heath Row

London airport owner seeks injunction against weeklong climate protest We’ve got juicy legal goings-on from London, and while it’s probably not true that all involved are wearing long, white wigs, we like to picture it that way. Here’s the deal: in mid-August, an estimated 5,000 protesters will descend on London’s Heathrow Airport for a weeklong […]

Climate marches kick off in New Hampshire and Iowa

A scholar-in-residence at Middlebury College, Bill McKibben is the author of The End of Nature, the first book for a general audience on climate change, and, most recently, Deep Economy: The Wealth of Communities and the Durable Future. He serves on Grist’s board of directors. Thursday, 2 Aug 2007 LITCHFIELD, N.H. The climate movement is […]

It’s a thing

Tom Konrad ponders the ethanol situation and wonders: what if, instead of feeding most of our corn to cows, and then growing a bunch of grass to make cellulosic ethanol, we use all the cow corn for ethanol and feed the grass to the cows? Gimmicky hook, but quite a fact-filled, educational article.

It’s coming soon

Technology Review has an article on thin-film solar, mostly focusing on First Solar. This stuff is very, very close to competitive with conventional solar panels and on a clear path to being competitive with traditional fossil-based electricity sources. It’s an exciting time. Speaking of solar excitement: A team at the Univ. of Delaware has just […]

His new piece says so in downright shrill terms

Jeff Goodell (see Grist interview) is apparently incapable of writing anything I don’t love. The latest is a piece in Rolling Stone called "Ethanol Scam." It’s downright shrill! Here’s what Goodell has to say about the ethanol hype: This is not just hype — it’s dangerous, delusional bullshit. Ethanol doesn’t burn cleaner than gasoline, nor […]

Should we be surprised?

This post was written by Kari, the ClimateProgress assistant.

A year and a half overdue, the Bush Administration finally submitted its Climate Action Report -- 2006 (CAR) last Friday afternoon, with hardly any mention by government officials of the report or its shameful findings (like a 15.8 percent increase in U.S. emissions since 1990).

While the mainstream media has been either silent or blind to the report's release, major kudos are due to the blogosphere. The few adept, new media journalists to blog on the report include Kevin Grandia from DeSmogBlog and Rick Piltz at Climate Science Watch.

Stupid on smart meters

Southern California Edison wants to distribute smart meters to its customers. That’s a great idea. Consumer group Utility Reform Network is fighting it. That is, as Kevin says, immeasurably stupid. Argh.

No surprises here, please

The electricity grid doesn't like surprises. Sudden voltage spikes or sags do not a healthy grid make. So proponents of large-scale solar and wind are working to create tools to smooth over volatility issues, so these generating resources can be integrated seamlessly onto the grid. If we're going to be in a position to rely on more solar and wind power and use these to replace significant amounts of power generated from coal, the grid planning and dispatch issues must be addressed.

Which brings us to yesterday's announcement by Tucson Electric Power (TEP) that they have received a $100,000 federal grant to study the problem as it relates specifically to solar power. Under the grant, they will "evaluate how effectively solar energy systems can replace traditional utility generating resources."

TEP will also evaluate "the true costs and benefits" of the almost 400 photovoltaic (PV) systems their customers have already installed in their service area through their SunShare program.
