Global Warming Legislation
• Climate Security Act: Senate debate next week!– Cap and trade system for carbon– Energy cost assistance– Adaptation funds– Major investment in clean energy

The Need for a Balanced Energy Plan
• Rising costs of historically inexpensive natural gas
• Uncertain future fuel supply• Rising capital construction costs• Imminent pollution regulations

The Balanced Energy Plan: Modeled Renewable Energy Components
• Wind (e.g., Fire Island) 50 MW • Biomass (e.g., FBK co-firing) 4 MW • Landfill Gas (e.g., Anch) 3 MW • Tidal (e.g., Knik Arm) 0-5 MW• Hydro (e.g., Lake 330 MW
Chakachamna)

New Fuel Price Estimates
• Goldman Sachs: up to $200/barrel oil within two years
• This scenario may make a more aggressive renewable portfolio competitive . . . Stay tuned!

The Balanced Energy Plan: Advantages
• Decreased fuel price risk• Decreased regulatory risk• Decreased air pollution• Increased energy efficiency• But development sometimes
uncertain, e.g. Mount Spurr megasite

BEP vs. BAU Energy Demand
![Page 19: A Balanced Energy Plan for Alaska’s Railbelt Opportunities for End-Use Efficiency/Conservation and Renewable Energy 2008-2040 Prepared for the Alaska Clean.](https://reader031.fdocuments.net/reader031/viewer/2022020417/56649e355503460f94b23507/html5/thumbnails/19.jpg)
Evaluating the Plan• Energy savings under all projected
scenarios ranging from $38-581 million (2015-2040):
• Equivalent levels of electric system reliability
• Reduce CO2 emissions by roughly 25% for the Railbelt as a whole

Implementing the Plan: State Policies and Programs Needed
• Commercial Building Code • Expand EE Program to Commercial Audits, loans for improvements• Pay As You Save loans for
commercial ratepayers (Utilities/RCA)
![Page 24: A Balanced Energy Plan for Alaska’s Railbelt Opportunities for End-Use Efficiency/Conservation and Renewable Energy 2008-2040 Prepared for the Alaska Clean.](https://reader031.fdocuments.net/reader031/viewer/2022020417/56649e355503460f94b23507/html5/thumbnails/24.jpg)
Implementing the Plan: State Policies and Programs Needed
• Residential Building Code (BEES)• Smart Meter Program• Net Metering

Implementing the Plan: Federal Policy
• Renewable Energy Tax Credits• Renewable Portfolio Standard • Global Warming Legislation w/ large
investment in clean technologies
