5 Our Energy Demands

6 ENERGY Impact of Increased CA Population

7 ENERGY …Yet Stabilized Per Capita Electricity Source: 2007 Integrated Energy Policy Report – IEPR Committee Draft, Report No. CEC CTD, October 2007, California Energy Commission

8 Source: 2007 Integrated Energy Policy Report – IEPR Committee Draft, Report No. CEC CTD, October 2007, California Energy Commission ENERGY Electricity Consumption by CA Sector Electricity consumption is dominated by the commercial sector, followed closely by residential.

9 Urban Water Use by CA Sector WATER Source: CUWCC

10 Energy Impacts of Water Use

11 Water & Energy Use Relationship ENERGY At Issue: Our region is in an extended dry period and needs to conserve our precious water resources Compounding the concern is the impact on electricity and natural gas use and its relationship to water use Our Objectives: An appreciation for the direct link of water and energy use and associated environmental impacts Opportunities to reduce water and energy use

12 Water & Energy Use Relationship ENERGY According to the California Energy Commission, water treatment and transport represent: 19% of Californias electricity consumption 32% of Californias non-power-plant natural gas consumption 88 million gallons per year of diesel fuel use Note that the energy component represents a significant portion of water rates

17 Environmental Impacts

18 Impacts from Water/Energy Use IMPACTS Energy and water end-use creates the following environmental impacts: Climate Change potential associated with greenhouse gases from fossil fuel power production and use Air Pollution related to smog, acid rain, particulates and reduced views Land Pollution with mining and operations for fuel extraction, power production, building dams/reservoirs Water Pollution affiliated with fuel extraction and thermal cooling for power production, building dams/reservoirs

19 Global Warming Headline – San Diego CLIMATE

20 Global Warming Policy – California CLIMATE Global Warming Solutions Act (AB-32) Signed by Governor Schwarzenegger on Sept. 27, 2007 Caps Californias GHG emissions at 1990 levels by 2020 The first such GHG enforceable state- wide program in U.S.

21 Resource Management Initiatives CLIMATE Various local, state, national, international initiatives that have stated climate change goals: Climate Smart Western Regional Climate Action Initiative San Diego Regional Sustainability Partnership* U.S. Green Building Council Step It Up Imperative Architecture 2030 Etc. *Co-Producer of todays Energy/Water Panel

22 Benefits of Less Energy/Water Use

23 Saving Water Offers Multiple Benefits WATER Preserves precious water resources Lowers operational costs Fosters economic development Protects from impending water shortages Reduces urban runoff minimizing pollution Rapidly implemented compared to supply additions Decreases energy consumption …which in turn

24 Saving Water Indirectly Saves Energy ENERGY Saves consumers and businesses money Helps with economic development Changes the energy supply and demand balance and puts downward pressure on energy prices Decreases reliance on energy imports Lowers air, water and land impacts from mining, production, transmission and use of energy sources Reduces carbon emissions, helping to temper gases that contribute to global climate change

25 Energy Use Reduction Model MODEL Efficiency Conservation Demand Response

26 Water Use Reduction Model MODEL Efficiency Conservation Demand Response

27 Overall Model for Decreased Impacts MODEL Reductions: Development: Smart Systems: Initiatives: Water, Materials, Waste, Energy, Fuel, Pollution, CO 2, CH 4 Green Building, Urban Infill, Design, Integration, Clean Clusters Automation, Smart Grids, Electricity Storage & Dispatch, Biomimicry Organizational, Government, Personal

28 Energy/Water Efficiency Opportunities EFFICIENCY Common areas of focus include: Site planning, landscaping & hardscaping Building envelope/shell (foundation, floors, walls, and roof) Mechanical (HVAC&R, water heating, pumping) Electrical (motors, transformers, etc.) Lighting (indoor and outdoor) Appliances Office equipment, electronics & plug loads

29 Design Integration: Green Buildings GREEN BUILDING

30 Definition of Green Buildings GREEN BUILDING Green Building is a process to create buildings and supporting infrastructure that… Minimize the use of resources Minimize harmful effects on the environment Create healthier environments for people

31 Definition of Green Buildings GREEN BUILDING Green buildings commonly address opportunities in the following five categories: SUSTAINABLE SITES WATER EFFICIENCY ENERGY & ATMOSPHERE MATERIALS & RESOURCES INDOOR ENVIRONMENTAL QUALITY

32 Green Building Savings GREEN BUILDING

33 Available Support Programs

34 Local, State and Federal Education Technical Assistance Financial Incentives Tax Rebates Depreciation Allowances Low-Interest Financing Permit Fee Reductions Mandates, Codes, Guidelines & Rating Systems Etc. Incentive and Support Programs SUPPORT
