    4. 1. Alternative Energy Sources Strategic Overview Electric Utility Basic Mission: Provide reliable, affordable electric services to meet customers’ needs and community requirements

    5. 1. Alternative Energy Sources Strategic Overview Power Supply Options

    6. “Today I challenge our nation to commit to producing 100 percent of our electricity from renewable energy and truly clean carbon-free sources within 10 years.” Al Gore July 17, 2008 1. Alternative Energy Sources Strategic Overview

    7. 1. Alternative Energy Sources Strategic Overview The Man with the Plan? Build Wind to offset natural gas generation. Use natural gas as transportation fuel. “The United States is the Saudi Arabia of wind power.” “An economic revival for rural America.” “A cheap new replacement for foreign oil.” T. Boone Pickens

    8. 2. Why Alternative Energy? Rising Energy Prices/Future Construction Costs Environmental Drivers Energy Security/Independence Technology Advancements Government Emphasis Commercial Customers/ Community Focus Economic Development

    9. 2. Why Alternative Energy? A. Rising Energy Prices/Future Construction Costs

    10. 2. Why Alternative Energy? B. Environmental Drivers Biggest Concern: Climate change/greenhouse gases (GHG) Carbon emissions reduction – carbon footprints Key Question: Are alternative energy sources the “low-hanging fruit” to reduce carbon emissions? Other environmental concerns: Air Water Land-use

    11. 2. Why Alternative Energy? C.
