What is Cool Counties?

Transcription

1 Hennepin County

2 What is Cool Counties? A pledge to take action on Climate Change Inventory greenhouse gas emissions from internal operations Implement policies and programs to reduce emissions Coordinate efforts with Minnesota State departments Support state legislation that is consistent with Hennepin County s goals Urge federal action to reduce GHG emissions

3 Why Join Cool Counties? Minnesota codified GHG reductions in 2007 Enhances HC policies & programs for energy efficiency Ensures measurement & documentation of HC s emission reductions Provides direction to county departments

4 Minnesota Goals Compared to Cool Counties GHG Emission Reduction Goals Cool County MN % Goal Year

5 Compile an accurate emissions inventory Create emissions baseline and past 3-5 years accomplishments 86 owned facilities, 57 leased facilities, 676 vehicles Establish recordkeeping requirements and protocols; identify responsible parties Recommend reductions from County operations Review & Assess GHG monitoring and reporting protocols Identify federal, state & other grant opportunities

14 Transportation 5% bio-diesel in 2004 increased to 13.5% in 2008 Shared E85 fueling station with City of Minneapolis Adopted new idling policy Downsizing vehicles 8 hybrids, 215 flex fuel, 175 biodiesel Experimenting with nitrogen filled tires Converted 50 signals to LEDs, saving over 400,000

15 Transportation ARRA Transportation Electrification stimulus project Ford to provide plug-in electric vehicles to participating metro-area government agencies Xcel Energy to provide enhancements to the electrical grid in support of usage by plug-in hybrid vehicles Participating government agencies to provide infrastructure to accommodate the vehicles (freestanding plug-in stations, outlets near parking)

16 HERC Steam line constructed to connect to downtown loop: Energy equivalent to heat & cool 1,500 homes Joint Energy Efficiency Plan with Xcel; conservation projects/annual savings potential include: Compressed air overhaul: 800,000 kwh Turbine replacement: 9,000,000 kwh Engineering assistance upgrades: 1,000,000 kwh Lighting upgrades: 1,200,000 kwh
