14. 14 C. Bauer, Washington Coal Club, 05/14/08 “Meantime, as Asian buyers grab more LNG from the Atlantic basin, U.S. prices, though at 27-month highs, still look cheap.” “Overall, U.S. imports of LNG have slid over the past nine months to a five-year low, and natural-gas inventories are running relatively low... If the U.S. is unable to attract LNG supply this summer, prices could spike up sharply within a few months if a hot summer were to reduce the ability to build a cushion of gas going into next winter.” Wall Street Journal on LNG (April 18, 2008) Wall Street Journal, Surge in Natural-Gas Price Stoked by New Global Trade, Page1, April 18, 2008

16. 16 C. Bauer, Washington Coal Club, 05/14/08 Summary  U.S. power generation industry is at a critical juncture, with social pressures and pending legislation demanding massive changes  Competing demands for reliable, low-cost energy and climate change mitigation appear incongruent  Our Nation’s liquid fuel dependence on foreign resources continues to grow  Uncertainty of regulatory outcomes and rising costs impact industry’s willingness to commit capital investment, endangering near-term production capacity  The United States must foster new processes that address conflicting energy objectives simultaneously
