Harold McGee's article on "green" pasta cooking offers hope:
After some experiments, I’ve found that we can indeed make pasta in just a few cups of water and save a good deal of energy. Not that much in your kitchen or mine — just the amount needed to keep a burner on high for a few more minutes. But Americans cook something like a billion pounds of pasta a year, so those minutes could add up.
My rough figuring indicates an energy savings at the stove top of several trillion B.T.U.s. At the power plant, that would mean saving 250,000 to 500,000 barrels of oil, or $10 million to $20 million at current prices. Significant numbers, though these days they sound like small drops in a very large pot.
