Energy Impacts of Water Use

11

Water & Energy Use Relationship ENERG

Y

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 ENERG

Y

According to the California Energy Commission, water treatment and transport represent: 19% of California’s electricity

consumption 32% of California’s 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 UseIM

PACTS 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

Global Warming

Solutions Act (AB-32)

Signed by Governor Schwarzenegger on Sept. 27, 2007Caps California’s GHG emissions at 1990 levels by 2020The first such GHG enforceable state-wide program in U.S.

21

Resource Management InitiativesCLIM

Benefits of Less Energy/Water Use

23

Saving Water Offers Multiple BenefitsW

ATER

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 EnergyEN

ERGY

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
