3. US Natural Gas SupplyIncreasing Reliance on Unconventional Production Shale Took 10 Years to Grow 8 bcf/d Unconventional: Tight Sands, CBM Offshore Conventional Decline Conventional Declines Offset by Increase in Unconventional production; Shale's forms about 10% of total supply Source: U.S. Energy Information Administration, Annual Energy Outlook 2009

29. Historical “Black eyes” for Natural Gas • Reserves – “We’re running out of gas” • Infrastructure • Price Volatility

30. What’s Changed • Shale Production: Historic • Infrastructure: More Pipelines • More Storage • LNG Capability • Cleanest Fossil Fuel (By Far!) • Price Volatility: CFTC Oversight / Congressional Actions??
