What is the Water-Energy Relationship where you live or work?

Slide12 l.jpg

California’s Energy Efficiency Programs’ Resource Value Compared to a Potential Water Use Efficiency (WUE) Program

How do your energy efficiency programs compare to the potential energy savings due to water use efficiency?

Water energy relationship synergies l.jpg

Water-Energy Relationship:Synergies

  • End-User Water and Energy Conservation

    • Saving water can save energy

    • Saving energy can save water

  • Improve Price Signals

    • Time of use water rates and meters

    • Time of use electric rates and meters

  • Water and Wastewater Utility Operational Efficiency

    • Increasing water and wastewater system efficiency reduces energy in the water use cycle

  • Water Storage

    • Increased water storage and more flexible water storage shifts peak energy requirements

    • Pumped storage increases peak electric generation and improves electric system efficiency

  • Renewable Generation by Water and Wastewater Utilities

    • Increase generation from in-conduit hydro and biogas. Add generation from solar and wind.

    • Assist in meeting California’s renewable generation goals

If we did all this,

what would be the combined impact on GHG emissions?

  • The Re-Training and Accreditation of Plumbers

  • GreenPlumbers® training programs are designed to assist plumbers in understanding their role in relation to Environmental & Public Health, and to provide their customers with up to date information and advise on:

    • Latest technology and energy saving appliances

    • Practical appliances & installation knowledge

    • Environmental impacts of plumbing services, appliances and household practices

    • Rebates, incentive programs, and consumer information

    • Energy/water/cost savings (short term and long term cost comparisons and environmental benefits)

Do you know l.jpg

Do You Know:

  • Anyone who waits a long time to get hot water somewhere in their house? At their job? In their favorite restaurant?

  • Any communities that have building or appliance energy standards or incentive programs? Green building programs?

  • Someone who has ever run out of hot water?

  • Any health inspectors who are enforcing compliance with hot water requirements in kitchens and restrooms?

  • Someone who is thinking about charging their kids for each shower they take?

  • Anyone who is tired of adjusting their lifestyle to the performance of their water heating system?

  • Any communities that have a “you can’t build unless you can guarantee a long term supply of water” ordinance?

  • Anyone who wants instantaneous hot water?

  • Someone who thinks that a tankless water heater is instantaneous?

  • Anyone who would like to learn how to get hot water to every fixture wasting no more than 1 cup waiting for the hot water to arrive?

The Challenge

Deliver hot water

to every fitting or appliance

wasting no more energy

than we currently waste and

wasting no more than 1 cup

waiting for the hot water to arrive.

Complete Culture Change For Plumbers

It’s not an option – It’s a necessity

GreenPlumbersUSA GOAL:

To Retrain 15,000 plumbers in California

and 40,000 in the United States


A Green Army of55,000 Plumbers

Saving Water in 165,000 Houses Per Day

= 33 Million Houses Per Year

Dr. James E. Hansen, continued

  • “Warming of more than 10C above today’s level will make the Earth warmer than it has been in a million years”.

  • “Business-as-usual, with fossil fuel CO2 emissions continuing to increase will mean an additional warming of 20C to 30C this century and will make the Earth a different planet.”

  • “At 20C to 30C the new equilibrium sea level is approximately 25 meters (80 feet) higher than today. Real world data suggest sea level changes in centuries rather than millennia.”

  • “Action must be prompt, otherwise CO2- producing infrastructure will be built within a decade that will make it impractical to keep further warming under 10C”.

  • “I refer especially to the large number of coal-fired power plants that China, the U.S. and India are planning to build…”

Adopt these Targets

  • All new buildings, developments and major renovations meet a fossil fuel energy-consumption performance standard of 50% of the regional (or country) average for that building type.

  • That at a minimum an equal amount of existing building area be renovated annually to use 50% of the fossil fuel energy they currently consume.

  • Increase Fossil Fuel Reduction Standard to:

    • 2010 – 60%

    • 2015 – 70%

    • 2020 – 80%

    • 2025 – 90%

      Goal is to be Carbon Neutral by 2030

      No Fossil Fuel to Operate our Buildings
