  • The Alabama Environmental Council, the Alabama Rivers alliance received funding from the World Wildlife Fund to develop a program to connect the dots between energy usage and water usage. The first step is the creation of this presentation. The presentation is strongly modeled after The River Network’s Saving Water Saving Energy (many of these slides came from them) developed by former Director, Don Elder.

    1. 1. Saving Water, Saving Energy The Alabama Environmental Council The Alabama Rivers Alliance World Wildlife Fund The River Network
    2. 2. The Alabama Environmental Council The Alabama Environmental Council works for a healthy environment with an emphasis on clean air, efficient and renewable energy, and improved waste reduction practices. We provide a voice for Alabama now and for the future. From the low and gentle mountains of the north to the pure white sands of the coast, we breathe Alabama's air, drink Alabama's water and depend on Alabama's land. We recognize the positive link between a strong economy, a clean environment and a healthy, proactive citizenry. www.aeconline.org
    3. 3. The Alabama Rivers Alliance Our purpose is to protect & restore Alabama's rivers. To do this, we advocate smart water policy, organize at the grassroots level, and teach citizens how they can protect their water. Our goal is to achieve healthy rivers, healthy people, and a healthy system of government for the state of Alabama. www.Alabamarivers.org
    4. 4. World Wildlife Fund Southeast Rivers and Streams Initiative It is the vision of WWF to protect and restore the ecological health of the region’s rivers and streams to safeguard natural processes, conserve native species and reach a balance between the needs of people and nature. www.worldwildlife.org
    5. 5. The River Network <ul><li>River Network’s vision is to improve the quality of all fresh waters in the U.S. and the health of all people and ecosystems dependant upon them </li></ul><ul><li>Through their new Saving Water, Saving Energy project, River Network is working to show how much water and energy we can save, how we can do it, and how everyone of us can get started today. </li></ul><ul><li>www.therivernetwork.org </li></ul>
    6. 9. <ul><li>Saving energy by saving water is one of the best strategies available to decrease climate change impacts! </li></ul>
    7. 10. Only 1% Fresh Water 97% Salt Water 2/3 of 1% is underground 1/3 of 1% is rivers, streams, and lakes 2% frozen in ice
    8. 11. According to data collected by NASA and the World Health Organization, 4 billion people will face water shortages by 2050.

    26. 35. Alabama’s Greenhouse Emissions - Carbon Dioxide (CO2) 1990 = 108 million tons 2005 = 142 million tons (13 th highest in the country) 23% increase in CO2 emissions since 1990 source: Federal Energy Information Administration

    91. 102. What could happen if we did all these things and if we quit thinking of stormwater and wastewater as problems and began thinking of them as resources ?
    92. 103. Imagine for a moment that Some day we will all have easy access to treated drinking water and 1-2 other sources of water...
    93. 104. Alternate sources already exist in some places <ul><li>Rainwater “harvested” on site </li></ul><ul><li>Stormwater detained near site </li></ul><ul><li>Graywater from dishes, washing machines, etc. </li></ul><ul><li>“ Wastewater” treated to levels adequate for re-use </li></ul><ul><ul><li>Sometimes higher levels </li></ul></ul><ul><ul><li>Often lower levels than required for surface water discharge </li></ul></ul>

    111. 122. So, we can easily imagine that some day we will all have easy access to treated drinking water and 1-2 other sources of water. How would we use it?
    112. 123. Highest quality water
    113. 124. <ul><li>Drinking, cooking and bathing account for less than 1/3 of indoor residential water use </li></ul><ul><li>Almost all other uses could be met as well with captured rainwater or other sources </li></ul><ul><ul><li>Other residential </li></ul></ul><ul><ul><li>All outdoor </li></ul></ul><ul><ul><li>Most industrial </li></ul></ul>

    122. 133. What else can I do? <ul><li>Talk to your water utility. Find out where your water is coming from </li></ul><ul><li>Talk to your friends about the water-energy connection </li></ul><ul><li>Identify groups to give this presentation to: churches, civic organizations, etc. </li></ul><ul><li>Write a letter to the editor </li></ul>
    123. 134. What else can I do? <ul><li>Let your elected officials know you care </li></ul><ul><ul><li>Tell the Joint Legislative Committee on Water Policy Management that we must make Conservation, Efficiency and Reuse a priority </li></ul></ul><ul><ul><li>Tell the Energy Committee that water is an important component in energy usage. (And that renewables must be a priority) </li></ul></ul>
    124. 135. What else can I do? <ul><li>Join efforts of a local environmental group </li></ul>www.aeconline.org www.alabamarivers.org
    125. 137. Climate change is the exact opposite <ul><li>We have the technology </li></ul><ul><li>We have the knowledge </li></ul><ul><li>Let’s get started </li></ul>Climate Change is no longer a technology or science issue. It is a matter social and political will.
