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.

The Alabama Rivers AllianceOur 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.

The River NetworkRiver 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

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.

Saving energy by saving water is one of the best strategies available to

decrease climate change impacts!

Only 1% Fresh Water

97% Salt Water

2/3 of 1% is underground1/3 of 1% is rivers, streams, and lakes

2% frozen in ice

According to data collected by NASA and the World Health Organization, 4 billion people will face water shortages by 2050.

Water is life.

There is no substitute.

It is our obligation to ensure its protection for the generations who will inherit our

planet.

Are Alabama’s water resources effected by the changes in our planet’s

climate?

Effects of Climate Change happening now:

•Sea levels are rising•Arctic sea ice is melting•Glaciers and permafrost are melting•Sea-surface temperatures are warming•Heavier rainfall cause flooding in many regions •Extreme drought is increasing•Ecosystems are changing•Hurricanes have changed in frequency and strength •Heat waves more frequent •Warmer temperatures affect human health

Hotter & dryerWarmer & wetter

Impacts:

More floods & erosion?More droughts & drinking water shortages?

Four simple questions

1. What are our greenhouse gas emissions in Alabama today?

2. Where do they come from?

3. How many of them are water-related?

4. How much energy could we save by saving water?

What is Alabama’s main electric utility company doing about its

CO2 emissions?

Not what you expect.

Here are some facts:

•Southern Company (Alabama Power’s parent company) is the top CO2 polluting company in the

US and the 4th worst in the world

•Spent $14,500,000 on lobbying expenses in 2007

•Strongest opponents of legal requirements to reduce air pollution.

Outdated, dirty, coal-fired power plants are a problem

About ½ of the nation’s power plants (548) are responsible

for emitting:

91% of CO2 emissions

98% NOx emissions

99% SO2 emissions

Some of the worst plants are in Alabama

Widows CreekColbert

Why are the old, dirtiest power plants

still in use? • The Clean Air act was

written in 1970

• Congress had a loophole which “grandfathered” these plants from new pollution standards

• They are still using pollution control technology from the 1950s and 60s, emitting 80-

90% more emissions than a new plant

Saving Energy by Saving Water

• Savings potential surprising, substantial

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

• Only environmental impacts are positive

Consider:

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

Source: US EPA

U.S. electricity used for residential water heating = More

than 104 billion kWh

US EIA 2001

U.S. electricity used for residential water heating = More

than 104 billion kWh

Comparison: All residential lighting, indoor and out =101 billion kWh

US EIA 2001

Municipal water/sewer plant energy use

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

• 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: Pacific Institute & NRDC* 60,000 drinking water treatment plants + 15,000 sewage treatment plants

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.

California’s annual water-related energy use

• 19% of all electricity

• 30% of natural gas*

• 88 million gallons of diesel fuel

Source: California Energy Commission

* Natural gas figure excludes that used by power plants

We estimate total current U.S. water-related energy use to be at least 360 billion kWh per year.*

* Includes water-related energy other than electricity (i.e., natural gas) in kWh equivalent.

How much is 360 billion kWh?

U.S. EIA

?


• 9% of all U.S. electricity use

• Entire residential electricity use of nearly 90 million Americans

(Alabama’s population times 20!)


• 33% more power than is generated by all U.S. dams in a year

U.S. EIA

How much is 360 billion kWh?• More than is generated by 100 typical coal-fired

power plants

• …So, if we only reduced our water-related energy use by 1% per year….We could retire (or leave unbuilt) one coal-fired power plant per year

• 720 tons of carbon monoxide

• 220 tons of hydrocarbons, volatile organic compounds which form ozone

• 225 pounds of arsenic

• 114 pounds of lead, 4 pounds of cadmium, and trace amounts of uranium

Thomas Edison once said that burning fossil

fuels for power production is like burning

your front door for heat.

Reducing our electricity use is crucial in addressing the Climate Change issue for

the health of our planet and ALL its inhabitants.

• If we cut our water use in half, we cut our water-related energy use by about half

• We can easily cut per capita water use – By well more than 10% in just a few

years– By well more than 50% over the next 50

yearsIf we set our minds to it…

National Water Use

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

What we aren’t talking about

We are talking about arevolutionary change in water use

and management in Alabama

In phases

3-5 years 5-25 years 25-50 years

Old water model

• Single large source in an entire region• All water from that source treated to drinking

water quality• Little of that water actually used for drinking• All “wastewater” (and a lot of rainwater too)

conveyed to central point for treatment• All discharged to single surface water point

Saving WaterA comprehensive, integrated approach

Conservation

ReuseEfficiency

Conservation

ReuseEfficiency

Conservation = Reducing Waste

• Does not have to mean hardship

• Does mean changing some behavioral habits

Drought Tool: short-term relief

Planning Tool: lessen gap between demand and available supply, lessen the system peak, provide water for future growth

Environmental Tool: provide more water for aquatic habitat and flows for water quality and reduce energy usage

Economic Tool: defer capital facilities for drinking water and wastewater treatment

Multiple Benefits of Conservation

Advancing Conservation

• Education• Incentives• Laws• Pricing

Significant conservation potential virtually everywhere

Should be the foundation of our water planning

To maximize, we should use all the tools

Penalize or prohibit profligate

waste

Encourage and reward

stewardship

Conservation

ReuseEfficiency

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/

Home efficiency potential

• “Water Sense” EPA-certified are at least 20% more efficient than similar devices currently in marketplace – and much more efficient than many older devices still in homes

• If just 10% of existing fixtures were replaced with devices just 20% more efficient, could save 128B gallons/year – enough to supply water to 3.5 million people

* Source: US EPA

Outdoor use• Better targeting of use

– Location– Timing

• Better methods of use– Drip irrigation– Etc.

Of the 7 billion gallons of water used outdoors on the average day, as much as 50% is wasted due to wind, evaporation, improper system design, installation or maintenance. – US EPA

Infrastructure efficiency

• Repairing, maintaining and operating systems– Leaks

• In U.S., more than 20% of water is lost in infrastructure leaks before it ever reaches homes or businesses

• In developing world, figure often more than 50%

– Pumps• Better pumps don’t save water, but save much energy

• Smaller-scale, decentralized systems– Appropriate technology in many situations– Can be managed centrally

Businesses & Institutions• Efficiency potential usually as great or

greater than residential

• Payback periods faster (because multiple users)

• Financing easier

Industry and agriculture

• Some industries have already improved dramatically

• Almost all still have significant potential

• Most still have enormous potential

Advancing Efficiency

• Education

• Standards

• Requirements

• Phase-outs

• Incentives

• Retrofit programs (utility-sponsored)

Water and energy utilities can help

• Many water utilities need paradigm shift– Purpose isn’t to sell more water– It’s to meet customers’ real water needs better

• Many energy utilities do too– Many have long run effective retrofit programs for

light bulbs, etc.– Water efficiency retrofits make at least as much

sense

• Water and energy utilities should work together on water efficiency programs

Conservation

ReuseEfficiency

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?

Imagine for a moment that

Some day we will all have easy access to treated drinking water and 1-2 other sources of water...

Alternate sources already exist in some places

• Rainwater “harvested” on site• Stormwater detained near site • Graywater from dishes, washing

machines, etc.• “Wastewater” treated to levels adequate

for re-use– Sometimes higher levels– Often lower levels than required for surface

water discharge

Problems with today’s stormwater approach in populous areas

• During/right after storms– Pollution– Flooding

• During dry spells– Lower flows– Higher pollutant concentrations

• In general– Less groundwater recharge– Radically altered flow regimes

Can we turnthese “problems”

intosolutions?

There are many home systems for rainwater harvest

• Small to large scale

• Simple to very sophisticated

SmartStorm

Rainwater harvesting system in Springville, AL Provides 100% of household use water

With strong conservation efforts, this family of 2 only needs rainwater!

Underground Rainwater Harvesting System in Argo, AL

Seattle’s King Center

• 1600 employees

• 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

Jenkins Brick Moody Facility

Detained stormwater

Treated wastewater

Many potential uses of treated “wastewater”

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

For more info: http://www.saws.org/our_water/recycling/

Dos Rios recycled water outfall

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?

Highest quality water

• Drinking, cooking and bathing account for less than 1/3 of indoor residential water use

• Almost all other uses could be met as well with captured rainwater or other sources– Other residential– All outdoor– Most industrial

What can I do?

What can I do? Remember to change your lightbulbs

What else can I do?

• Get your family involved – make a water use graph

• Start harvesting your rain water

What else can I do?

•Talk to your water utility. Find out where your water is coming from

•Talk to your friends about the water-energy connection

•Identify groups to give this presentation to: churches, civic organizations, etc.

•Write a letter to the editor

What else can I do?

•Let your elected officials know you care

–Tell the Joint Legislative Committee on Water Policy Management that we must make Conservation, Efficiency and Reuse a priority

–Tell the Energy Committee that water is an important component in energy usage. (And that renewables must be a priority)

What else can I do?

•Join efforts of a local environmental group

www.aeconline.org www.alabamarivers.org

Climate change is the exact opposite

•We have the technology

•We have the knowledge

Let’s get started

Climate Change is no longer a technology or science issue. It is a matter social and political will.
