Saving Energy by Saving Water

River NetworkOctober 2007

Page 52: 1 Webcast sponsored by EPA’s Watershed Academy Susan Kaderka, Director, National Wildlife Federation’s Gulf States Office Don Elder, President, River Network.

52

Saving Energy by Saving Water

• Savings potential surprising, substantial

• Quicker, cheaper and more reliable results than most potential strategies

• Only environmental impacts are positive

Page 53: 1 Webcast sponsored by EPA’s Watershed Academy Susan Kaderka, Director, National Wildlife Federation’s Gulf States Office Don Elder, President, River Network.

53

Perspective:

• In five minutes, a hot water faucet uses as much energy as a 60-watt bulb uses in 14 hours.

Source: US EPA

Page 54: 1 Webcast sponsored by EPA’s Watershed Academy Susan Kaderka, Director, National Wildlife Federation’s Gulf States Office Don Elder, President, River Network.

54

Municipal water/sewer plant energy use

• U.S. annual total* = 75 billion kilowatt hours per year

• 3% of total U.S. consumption of electricity

• Equal to entire residential electricity demand of California

• More than entire energy-intensive pulp/paper and petroleum sectors combined

• Public bill = Already $4B/yr. Increasing.

Sources: US EPA, Alliance toSave Energy, Pacific Institute & NRDC* 60,000 drinking water treatment plants +

15,000 sewage treatment plants

Page 55: 1 Webcast sponsored by EPA’s Watershed Academy Susan Kaderka, Director, National Wildlife Federation’s Gulf States Office Don Elder, President, River Network.

55

Other water-related energy use includes…

• Groundwater pumping• Interbasin transfers• Pumping water to drinking water treatment

plants and from there to homes• Heating water in homes, businesses and

institutions• Heating and cooling water in industries• Pumping water to sewage treatment plants and

discharge points• Etc.

Does not include:• Energy used by the more than

60% of homes that heat with gas instead of electricity.

• Energy used for pumping water uphill and between basins

• Any commercial or industrial use of energy to pump, treat, heat and cool water

• Any agricultural energy use to pump water

• Etc…

Public water treatment + residential water heating = about 180 billion

kWh/year in U.S. today

Page 59: 1 Webcast sponsored by EPA’s Watershed Academy Susan Kaderka, Director, National Wildlife Federation’s Gulf States Office Don Elder, President, River Network.

59

We estimate total current U.S. water-related energy use to be at least 300 billion kWh per year.*

* Includes energy other than electricity in approximate kWh

equivalent.

Easily achievable water use reductions could allow us to

• Retire hundreds of dirty power plants much sooner

• Give us cleaner, healthier air to breathe

• Significantly advance overall effort to reduce greenhouse gas reductions

• Keep much more water in streams and lakes where it belongs

Supply-side emphasis

“Must sell more water to generate more revenue!”

Page 71: 1 Webcast sponsored by EPA’s Watershed Academy Susan Kaderka, Director, National Wildlife Federation’s Gulf States Office Don Elder, President, River Network.

Demand-side emphasis

Revenue – Expenses = Margin

“It’s at least as good to reduce demand as it is to increase supply!”

Efficiency = Getting more performance out of every drop used

• No hardship at all

• Saves resources and money

• Payback periods quick

• Tremendous existing potential

Homes

• Toilets

• Faucets

• Showerheads

• Washing machines

• Dishwashers

• Hot water heaters*

* Tankless models save little or no water, but save a lot of energy

EPA Labeling Program

• Helps consumers ensure they are buying high-performing water-efficient devices

• Perform as well or better than water-wasting devices

• http://epa.gov/watersense/

Businesses & Institutions

• Efficiency potential usually as great or greater than residential

• Payback periods faster (because multiple users)

• Financing easier

Advancing Efficiency

• Education

• Standards

• Requirements

• Phase-outs

• Incentives

• Retrofit programs (utility-sponsored)

80

Efficiency potential(above and beyond conservation potential)

• U.S. Water efficiency potential: At least 25% (conservative estimate)

• Could achieve half this potential in next 10 years, most of rest in next 15

• So, with conservation and efficiency, we could reduce our urban water use by 35% or more within 25 years

• Small to large scale

• Simple to very sophisticated

• Rainwater harvesting meets >60% of entire facility’s water needs

• Saves >1.4 million gallons of drinking water per year

• Also keeps runoff from entering storm sewers

San Antonio wastewaterrecycling

• Already has large-scale reuse program

• Primarily commercial and industrial purposes today, served by 80 miles of delivery pipeline

• Source is cheaper and more reliable

• Already reducing demand on Edwards Aquifer and region’s rivers by 29 million gallons per day

San Antonio wastewaterrecycling program

• City committed in 1996 to major expansion

• Now building a 64-mile pipeline around entire city for broader delivery

• Also capturing gases in the process and generating power with it
