Energy Impacts of Water Use

11

Water & Energy Use RelationshipEN

ER

GY

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 RelationshipEN

ER

GY

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

Impacts from Water/Energy UseIM

PA

CTS 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

WA

TER

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

EN

ER

GY

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
