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

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

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

Energy/Water Efficiency Opportunities
EFFICIENCY

• Common areas of focus include
• Site planning, landscaping hardscaping
• Building envelope/shell (foundation, floors,
  walls, and roof)
• Mechanical (HVACR, water heating, pumping)
• Electrical (motors, transformers, etc.)
• Lighting (indoor and outdoor)
• Appliances
• Office equipment, electronics plug loads

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
