Also on page C1, in another article, Soft Energy Prices May Be Costly Later, is a quote from T. Boone Pickens:

T. Boone Pickens, the energy-investment titan whose investment fund BP Capital Management bets big on higher energy prices, is adamant that oil prices remain on an upward trajectory and probably have bottomed for now. "I think you'll see $70 oil before $50," Mr. Pickens says in an interview. "We're depleting this natural resource. It's unavoidable."

Renewable Fuels May Provide 25% of U.S. Energy by 2025

WASHINGTON -- A new Rand Corp. study showing the falling costs of ethanol, wind power and other forms of renewable energy predicts such sources could furnish as much as 25% of the U.S.'s conventional energy by 2025 at little or no additional expense.

A second renewable-energy report soon to be released by the National Academy of Sciences suggests wood chips may become a plentiful source of ethanol and electricity for industrial nations because their forested areas are expanding, led by the U.S. and China.
