WASHINGTON, April, 25, 2006 - The industry is doing all it can to meet consumer energy needs, but it cannot meet U.S. energy challenges alone, API President and CEO Red Cavaney wrote in a letter to members of Congress. In the April 24 letter, Cavaney said the nation’s energy policy needs to focus on increasing supplies, energy efficiency, and encouraging responsible development of alternative and nonconventional sources of energy.
