Final Thoughts…• Natural Gas is a clean, domestic, abundant and secure energy that
is the energy bridge to the future
• Natural Gas is available today and in the future to meet theincreasing demand for electrical generation
Th l f N l G i idl i i h h• The supply of Natural Gas is rapidly growing with the proventechnologies currently in place
• Technologies exist that can increase the use of Natural Gas as agcleaner burning transportation fuel
• Domestic Natural Gas used for transportation could displace asignificant amount of the crude oil the U S currently importssignificant amount of the crude oil the U.S. currently imports
• In order to develop and produce our abundant Natural Gasreserves, regulatory policy must encourage the drilling for moreNat al GasNatural Gas
