Barriers to Public Sector Leaders?

One of the issues that arises in the public water utility sector is where are the leaders?  A recent online discussion of the issue identified a number of barriers to public sector leadership, which differentiates the public sector from the private sector.  The three issues were associated with risk tolerance in the public sector which stifles innovation, application of business principles to public sector efforts, and the lack of vision and understanding of consequences.  Related to the latter is the understanding of the various types and perspectives of expertise within the industry.  Over the next three blogs, we will talk about each.  Comments welcome of course.

So the first one.  For the most part, public officials, city managers, finance directors and elected officials, are particularly risk averse individuals as a group.  For one thing, their tenure in any given job is relatively short (city manager are aground 2-3 years).  Elected officials spend much of their time trying to stay in office, so clearly their leadership is guided by public opinion, never a strong point for leadership. Regulatory agencies can only be criticized, so why be innovative? For all three, plus the employees working beneath these folks, their performance is in the public eye and the public is rarely forgiving of continued or significant failures.  However, innovation is often correlated with risk, which suggests that the risk associated with failure may limit the pursuit or acceptance of innovation – instead keep doing what you have been doing because that creates no waves.  Nevermind that the same old way may be inefficient or outdated, the concern is the risk if a new idea fails.  The reality is to “stick with what works,” a mantra that has existed in the industry for many yeas, does not accept innovation easily.  Particularly of issue is organizations where many mid- and often upper division managers avoid decision-making, but may be particularly poignant in pointing out decision failures of others as a means to improve their own stock – “I’ve never made a bad decision.”  But as in baseball, sitting on the bench 0 for 0, means you have never had an at bat, so you have accomplished nothing, while the person who is 6/10 may have accomplished a lot.  It is successful risk taking that may lead to changes in the organization, changes in doing business, improvements in efficiency and new means to accomplish tasks or deliver services.  You need to think “outside the box,” to use an overused euphemism.

So the question is how do we get the public and the public officials to accept risk taking, and to relax their risk averseness?  For innovation to grow, we need leadership, which means risk tolerance.  After all doing the same thing over and over, and expecting different results is the definition of insanity isn’t it?

WHAT MAKES A GREAT LEADER?

WHAT MAKES A GREAT LEADER?

This a question that has puzzled researchers for some time.  Back in the 19th century we looked to enlightenment among people – mostly oriented to new ideas and processes that would move civilization forward.  That helped but did not provide full answers.  Of course we were still in the throes of the start of the industrial revolution.  We looked at psychology to show us how to find leaders at the turn of the 20th century, but that faded in favor of trying to determine traits that made good leaders in the 1920s.  The idea of traits faded as we started looking the style by which people managed (think all those tests out there), but soon found that management style, leadership perception and results were often not correlated.  In the 1990s we started looking at adaptation, but as Jim Collins points out the great companies seem to have leaders that are the opposite of the charismatic leadership many seek or seek to become.  It’s the plodders, who can adapt to changing facts or situations on the front lines, that seem to get results.  And we only tend to notice after the fact, or well into their leadership reign, not at the beginning.  In fact many of the best success stories received much criticism early on.

What this all seems to indicate is that leadership evolves, just as civilization evolves.  Those that can evolve and adapt to changing conditions appear to lead the most successful organizations, but are not often recognized as the best leaders.  No one set of characteristics in a person will fit each situation or challenge, but you need the ability to understand the context of the facts in order to chart a course and engage people in solutions.  Without buy-in, the problem will not be solved and most challenges require thought on the part of others who are committed to the same goals as the leader.  The leadership team concepts allows for the ability to delegate to those closest to the situation, or with the best skill set to resolve it, will achieve the best result and create personal accountability by creating a personal stake in the solution.

Engagement identifies another emerging hallmark of leadership which is that we all want to succeed and leaders tend to nudge their followers toward that success.  Good leaders always backstop their charges, and understand that not all situations will be resolved ideally and that there may be multiple means to resolve the problem.  That gives the followers the ability to “gamble” on innovative solutions without the fear of reprisals.  The fear of reprisals will eliminate innovation.  What you want is to lead your organization to be innovative.  Organizations that foster innovation can become more effective in their industry.  Isn’t that what we want?  Fostering innovation is how Google develops a lot of its applications.  They call it 20% time, where employees get to work on anything they want, with anyone they want, except their own projects.  Think GoogleEarth, gmail, and many others.  Dan Pink did an excellent discussion in his best seller “Drive.”  I recommend you check it out.  But then we need to ask, “When was the last time we tried something like 20% time in the utility industry?”

Should Coastal Utility Master Plans Include Sea Level Rise?

Planning is a process utilized by utilities in order to reach a vision of the utility as defined by the customers or the governing board, or to meet certain demands for service projected to be required in the future.  Understanding and managing the utility’s assets provides important information related to the ongoing future direction of the utility system.  However, the only method to develop that future direction is through the planning process.  Planning should be undertaken on a regular basis by all enterprises in an effort to anticipate in to anticipate needs, clarify organizational goals, provide direction for the organization to pursue and to communicate each of these to the public.  With water and wastewater utility systems, it is imperative to have ongoing planning activities, as many necessary improvements and programs take months or years to implement and/or complete.  Without a short and long-term plan to accomplish future needs, the utility will suffer errors in direction, build unnecessary or inadequate infrastructure and pursue programs that later are found to provide the wrong information, level of service or type of treatment.

Planning can provide for a number of long-term benefits – improvements in ISO ratings to lower fire insurance rates, renewal of improvements as monies become available, rate stability and most importantly – a “vision” for the utility.  In creating any plan for a utility system, efforts to understand the operating environment in which the utility operates must be undertaken.  Second, the needs of the utility must be defined – generally from growth projections and analyses of current infrastructure condition from repair records or specific investigations.  By funneling this information into the planning process, the result of the effort should be a set of clear goals and objectives needs to be defined (Figure 8.1).  However, the types of goals and objectives may vary depending on the type of plan developed.  There are 4 types of plans that may result from the planning process.

  • Strategic Plans – action oriented for management level decision-making and direction
  • Integrated Resource Plans – Actions for utility management to tie all parts of the system together
  • Facilities Plans – for SRF loans support
  • Master Plans – to support capital improvement programs

Any utility planning effort should start with a description (and understanding) of the local environment (built and otherwise).  An understanding of the environment from which water is drawn or to be discharged is important.  Both water quality and available quantity, whether surface or ground water, are profoundly affected by demand.  A reduced demand for surface water helps prevent degradation of the quality of the resource in times of low precipitation.  Reduction in the pumping of ground water improves the aquifer’s ability to withstand salt water infiltration, potential surface contamination, upconing of poorer quality water, contamination by septic tank leachate, underground storage tank leakage, and leaching hazardous wastes and other pollutants from the surface.  Over-pumping ground water leads denuding the aquifer or to contamination of large sections of the aquifer.  Planning for is necessary for surface water systems.  Therefore, source water protection must be a part of any water planning efforts, including the appropriate application sites and treatment needs for reuse and residuals.

So let’s toss sea level rise into the mix.  What happens when sea level rise inundates coastal areas with saltwater and increase freshwater heads inland?  How do we fix that problem and should be plan for it.  Clearly master planning should include this threat (as applicable), just as any regulatory issue, water limitation, disposal limit or change in business practices should be considered.  One means to reduce the impact of sea level induced groundwater levels is infiltration galleries that may operate 24/7.  These systems are commonly used to dispose of storm water (french drains or exfiltration trenches) but what happens if the flow is reversed?  Water will flow easily into the system, just as it does for riverbank filtration. The water must be disposed of, with limited options, but let’s toss a crazy idea out there – could it be your new water supply?  Just asking, but such a system would not be unprecedented worldwide, only in the coastal communities of the US.

Based on my last blog, his inquiry came to me.  And I think I actually have an answer:  when bakers and insurance companies decide there is real exposure.  Let’s see why it will take these agencies.  There is very little chance, regardless of good faith efforts, significant expertise, or conscientious bureaucrats to stop growth and development.  The lobby is simply too strong and local officials are looking for ways to raise more revenues.  Development is the easiest way to increase your tax base.  As long as there are no limits placed on develop-ability of properties (and I don’t mean like zoning or concurrency), development will continue.  But let’s see how this plays out.  Say you are in an area that is likely to have the street inundated permanently with water as a result of sea level rise (it could be inland groundwater, not just coastal saltwater).  For a time public works infrastructure can deal with the problem, but ultimately the roadways will not be able to be cleared.  Or say you are located on the coast, and repeated storm events have damaged property.  In both cases the insurance companies will do one of three things:  Refuse to insure the property, insure the property (existing) only for replacement value (i.e. you get the value to replace) but no ability to get replacement insurance, or the premiums will be ridiculous.  We partially have this issue in Florida right now.  Citizen’s is the major insurer.  It’s an insurance pool created by the state to deal with the fact that along the coast, you cannot get commercial insurance.  So Citizens steps in.  The state has limited premiums, and while able to meet its obligations, in a catastrophic storm would be underfunded (of course in theory is should have paid out very little since 2006 since no major hurricanes have hit the state, but that’s another story). 

As the risk increases, Citizens and FEMA, the federal insurer, have a decision to make.  Rebuilding where repeated impacts are likely to happen is a poor use of resources and unlikely to continue.  Beaches and barrier islands will be altered as a result.  The need will be to move people out of these areas, so the option above that will be selected will be to pay to replace (move inland or somewhere else).  Then the banks will sit up.  The banks will see that the value of these properties will not increase.  In fact they will decline almost immediately if the insurance agencies say we pay only to relocate.  That means that if the borrowers refuse to pay, the bank may not be able to get its money out of the deal on a resale.  We have seen the impact on banks from the loss of property values as a result of bad loans.  We are unlikely to see banks engage in similar risks in the future and unlikely to see the federal insurers (Fannie Mae, Freddie Mac) or commercial re-insurers like AIG be willing to underwrite these risks.   So where insurance is restricted, borrowing will be limited and borrowing time reduced.  That will have a drastic impact on development.  The question is what local officials will do about it?

There are options to adapt to sea level rise, and both banking and insurance industries will be paying close attention in future years.  Local agencies will need a sea level rise adaptation plan, including policies restricting development, a plan to adapt to changing sea and ground water levels including pumping systems to create soil storage capacity, moving water and sewer systems, abandoning roadways, and the like, and hardening vulnerable treatment plants.  Few local agencies have these plans in place.  Many local officials along the Gulf states refuse to acknowledge the risk.  What does that say about their prospects?  Those who plan ahead will benefit.  Southeast Florid a is one of those regions that is planning, but it is slow process and we are only in the early stages.

Groundwater Accelerates Sea Level Rise

Regardless of the causes, southeast Florida, with a population of 5.6 million (one-third of the State’s population), is among the most vulnerable areas in the world for climate change due its coastal proximity and low elevation (OECD, 2008; Murley et al. 2008), so assessing sea level rise (SLR) scenarios is needed to accurately project vulnerable infrastructure (Heimlich and Bloetscher, 2011). We know that sea level has been rising for over 100 years in Florida (Bloetscher, 2010, 2011; IPCC, 2007). Various studies (Bindoff et al., 2007; Domingues et al., 2008; Edwards, 2007; Gregory, 2008; Vermeer and Rahmstorf, 2009; Jevrejeva, Moore and Grinsted, 2010; Heimlich, et al. 2009) indicate large uncertainty in projections of sea level rise by 2100. Gregory et al. (2012) note the last two decades, the global rate of SLR has been larger than the 20th-century time-mean, and Church et al. (2011) suggested further that the cause was increased rates of thermal expansion, glacier mass loss, and ice discharge from both ice-sheets. Gregory et al. (2012) suggested that there may also be increasing contributions to global SLR from the effects of groundwater depletion, reservoir impoundment and loss of storage capacity in surface waters due to siltation. The loss of groundwater, mainly from confined aquifers, is troubling, and currently completely unknown. The contribution of carbon dioxide, commonly occurring in deep groundwater is also unknown. To gauge the risk to property in southeast Florida, Southeast Florida Regional Climate Compact and Florida Atlantic University reviewed twelve different projections of SLR and its timing. The consensus was 3” to 7” by 2030 and 9” to 24” by 2060. From the literature review and analysis, it was concluded that approximately 3 ft. of sea level rise by 2100 would a suitable scenario and time frame to illustrate the methodology presented in this article. To allow flexibility in the analysis due to the range of increases within the different time periods, an approach that uses incremental increases of 1, 2, and 3 feet of SLR was considered for risk scenarios. An issue normally ignored in sea level rise projections is groundwater. The importance of the groundwater table in the model is that it is responsible for determining the soil storage capacity. Soil is composed of solids, water, and air (voids). Soil storage capacity depends on physical and chemical properties, water content of the soil, and depth to the water table or confining unit (Gregory et al 1999). As the rain infiltrates the soil, unsaturated pores quickly fill up, effectively raising the water table (Gregory et al 1999). For example efforts, a groundwater surface elevation map was derived based well site information available from the USGS (http://groundwaterwatch.usgs.gov) that had a minimum of 35 years of continuous data. Using GIS, an inundation model was created in GIS by subtracting the groundwater surface model from the digital elevation model with the difference in elevation being the soil storage capacity. The photo shows the evolution of these features as applied to a section of northwestern Miami-Dade County. What this indicates it that the impact of sea level rise on low-lying inland areas may be far different that the projections using the bathtub models. It also means that wellfields, sewer mains, roadways and storm water systems will be affected far more quickly than projected from bathtub models. The method used here suggested that the estimated may be off by a factor of two of three.

OnSIte Power At Utility Plants?

Since Richard Nixon was President, the federal government has been talking about reducing our reliance of foreign oil.  Since 2008, our dependence has dropped from 57 to 42 percent.  The foreign oil has been replaced by domestic oil and gas, conversion of power plants to natural gas, and investments in renewable power like wind (4% US production and) and solar power.  Coal has remained a constant, although future regulations of coal plant emission may alter this.  Federal loans from DOE have included $13 billion for solar energy, 1.7 billion for wind and 10 billion for nuclear power.  All other renewables account for 1.2 billion.  Power companies have invested in the renewable technologies in part because of low loan rates from the federal government, and partly due to tax credits (2.2 cents/kW-hr), but power entities like NextEra Energy have made cleaner power a basis of their future.  So what does this have to do with water utilities?  First, water and wastewater plant are often the largest users on the power grind in communities.  This is why they are able to get load control agreements.  The peak demands are the load control agreements, which means power providers can construct fewer plants, and keep rates down.  At the same time water and wastewater utilities benefit fro reduced rates, but have construct backup systems (which are needed if the power grid fails anyway.  Benefit to both parties.  But as the demands for power on the grid increase, and as regional demands in areas that are substantially constructed already, locating new power is difficult.  Transmission losses are 6 or more percent, and involve complicated federal FERC regulations.  So the SMART grid issue is distributed power, and finding sites for distributed power might be tough.  Or maybe not.  Water and wastewater plants have land, so there is an obvious fit.  But the rub is that if the water and wastewater people own the facilities, it decreases the peak capacity, meaning the power entities must build more capacity.  So perhaps there is a means to get revenues (leases) to water folks, while helping the smart grid.  I am thinking about developing a project proposal for this.  Let me know if you are interested.  Meanwhile if you have a success story, I’d love to hear it.

Hi all

I am in the process of trying to develop a project on leadership in the water industry, focusing of who our leaders are now (individual), how we develop new leaders, barrier and incentives for leadership and issues. I thought the 3 biggest issues in the water industry post a couple weeks back was great. Share and let’s see if we can gain some traction. Looking forward to hearing from you all

What do you believe are the three biggest water challenges in the U.S.? Part 2

This question has been asked a couple times on on-line discussion groups.  It usually results in a short list of answers.  In the last post, I outlined the number one answer –  getting a handle on failing infrastructure.  The next issue has to do with water supplies.  You hear the argument that we need to get people to respect that drinking water as a limited resource, develop where water supplies are plentiful as opposed to arid regions that are water poor and protecting water sources instead of rendering it unusable in the process of using it. People (and their jobs) are moving to “more favorable” (read: warmer, more arid) climates, so people are now actually trying to grow rice and develop golf courses in the deserts of the Southwest US and complaining about “drought” conditions. The sustainability of groundwater supplies is often noted as a problem because much of the west relies on groundwater for agricultural irrigation. Having a 50 or 100 year management plan for an aquifer, which is how to insure there is water to last 50 or 100 years, is shortsighted, even though it doesn’t sound like it. Long term these areas could run out of water which will create significant economic impacts to these communities. More professionals should be involved in this discussion: regional growth planners; federal and state funders that offer ‘incentives’ to businesses to relocate their workers; city and county governments that accept these ‘incentives’ to beef up their budgets.

But just as cities market their community to developers and industry, it is interesting that marketing services is another issue.  I had a conversation where an elected official said it was inappropriate for government to market. Yet the bottled water industry does, power companies do, and cell phone companies do. Utilities ignore the people that put fliers on houses asking our residents to take a sample of their water, and then attacking the quality of our drinking water by explaining that having calcium and chlorine in the water is bad, should have been addressed long ago. Of course calcium and chlorine are in the water! Chlorine disinfects the water and then keeps the distribution system clean (especially an issue in warmer climates with TOC in the water). Our public is uneducated and we have been out-marketed for scare dollars for 40 years. That is an elected official, but also a water official problem.

This question has been asked a couple times on on-line discussion groups.  It usually results in a short list of answers.  The number one answer is usually getting a handle on failing infrastructure.  The US built fantastic infrastructure systems that allowed our economy to grow and use to be productive, but like all tools and equipment, it degrades, or wears out with time.  In addition, newer infrastructure is more efficient and works better. In many ways we are victims of our own success. People have grown used to the fact that water is abundant, cheap, and safe. Open the tap and here it comes. Flush the toilet and there it goes, without a thought as to what is involved to produce, treat and distribute potable water as well as to collect, treat, and discharge wastewater. Looking to the future, we should take education as one of our challenges.  Our economy and out way of life requires access to high quality water and waste water. So this will continue to be critical.  But utilities have not been proactive in explaining the condition of buried infrastructure in particular, and need more data. The same goes for roadways and many buildings.

Cities are sitting on crumbling systems that have suffered from lack of adequate funding to consistently maintain and upgrade.  In part this is because some believe that clean drinking water is a right instead of a privilege to be paid for. We gladly pay hundreds of dollars per month for cable television and cell phones, but scream at the costs for water delivered to out tap. The discussion usually continues along the lines of utilities are funding at less than half the level needed to meet the 30 year demands while relying on the federal government, which is trying to get out of funding for infrastructure for local utilities. Utilities are a local issue which is some ways makes this easier. Our local leaders to send help with the education (after we educate them), send less money going to the general funds and more retained by utilities.

Perhaps where we have failed is in educating the public. Public agencies are almost always reactive, as opposed to pro-active, which is why we continuously end up in defensive positions and at the lower end of the spending priorities. So we keep deferring needed maintenance. The life cycle analysis concepts used in business would help. A 20 year old truck, pump, backhoe, etc just aren’t cost effective to operate and maintain. We are not very successful at getting this point across.

Money is an issue, and will always be, but the fact that local officials are not stressed about infrastructure is in part because utility personnel are very good at our jobs, minimizing disruptions and keeping the public safe. We are not “squeaky wheels” and we don’t market our product at all. Afterall, is cable or your phone really more valuable that water and sewer?

Energy Leadership in the Water Industry

Water and energy systems constitute the foundation for modern civilization around the world.  Without water, societies never get started, and without power, it is difficult for economies to grow.  At the same time, modern power generating equipment needs water for cooling and processes, creating an interdependency between water and energy infrastructure and potential for conflict over water resources. As a result, the Energy-Water Nexus is a topic of great interest and discussion among federal policy-making and regulatory entities; private and public sector water and electric utilities; state and local governments, and many supporting technical, educational, professional associations. At the nexus of water and energy exists a host of societal issues, policy and regulatory debates, environmental concerns (local and global), technological challenges, and economic impacts that must be balanced or optimized to permit ongoing economic development for all (NETL, 2008).

Estimates indicate that from 1950 to 1980, demands for water increased steadily across all sectors, with 1980 being the peak water use year.  However, since 1980, withdrawals declined.  Despite the overall decline, the built environment demands continued increase. This of course ignore the natural environment demands, which may play a large part in the economic stability of some regions.  Unlike water demands, the total US power consumption continues to climb as a result of population increases.  The US Census Bureau (2004) projects that the national population will increase from 282 million people in 2000 to 420 million by 2050.  The Energy Information Administration (EIA) project, assuming the latest Census Bureau projections in its reference case, the U.S. population to grow by about 70 million in the next 25 years and electricity demand to grow by approximately 50 percent (EIA, 2006). More people, means more power.  More power means more water for cooling unless all new power is solar or wind, something highly unlikely.  On the current track, which suggests and expansion of fossil fuel plants, the power sector may be highly vulnerable to changes in water resources, especially those that are already occurring, and are likely to intensify, as result of climatic changes (Vorosmarty et al 2000, Bates et al 2008, Dai 2010, NETL 2010d).

Adding to the challenge is that planning by drinking water, wastewater, and electric utilities occurs separately and is not integrated. In the US, the energy sector uses 39% of the water withdrawals on an annual basis for cooling, immediately behind the 40% used by agriculture (Lisk et al, 2012; GAO, 2012).  Urban demands (12.6% of water use – Sanders and Webber, 2012) require clean water supplies to protect public health.  Both sectors need to manage supplies for changes in demands throughout the year, but because they are planned for and managed separately, their production and use are often at the expense of the environment (NREL, 2011). This separate planning occurs for a multitude of reasons, including tradition, regulatory limitations, ease, location, limited organizational resources, governance structure, and mandated requirements. However, as demands for limited water resources continue to grow among all sectors, and as pressures on financial resources increase, there are benefits and synergies that can be realized from integrated planning for both water and electric utilities and for their respective stakeholders and communities. The link between energy and water is important – water efficiency can provide a large savings for consumers and the utility.  Reduced energy consumptions benefits the consumer – but should always be considered as one of the first steps (Gould, 2011).  As a result, there is a need to move toward long-term, integrated processes, in which these resources are recognized as all being interconnected (NREL, 2011).  Only then can the challenges to fully to optimize management of water resources for all purposes be identified (Scanlon et al 2005).

The lack of planning creates the situation where competition for water between agriculture, power and urban uses will reach a tipping point (or beyond in many basins) as an expected increase in thermoelectric capacity by electric utilities, and an increasing prevalence of droughts could induce possible water shortages.  By 2025, Ciferno (2009) suggests the most vulnerable areas for water shortages are fast growing areas:  Charlotte, NC, Chicago, IL, Queens, NY, Atlanta, GA, Dallas, TX; Houston, TX, San Antonio, TX, and San Francisco.  Immediately behind these areas are Denver, CO; Las Vegas, NV; St Paul MN, and Portland OR (Ciferno,2009). Hightower (2009) notes that virtually all the states west of the Mississippi and many southeastern states will experience regional or statewide water shortages in the coming decade (2010-2020).  The South and the Southwest are particularly vulnerable (Glassman, et al, 2011) because they rely on air conditioning to provide a comfortable environment, which requires more power for a growing population, requiring more water for cooling power plants.

These projections come with recent experience that is likely to foretell the future.  The south, Texas and parts of the west have had repeated drought periods in recent history.  During the summer and fall of 2007, a serious drought affected the southeastern United States.  River flows decreased, and water levels in lakes and reservoirs dropped. In some cases, water levels were so low that power production at some power plants had to be stopped or reduced (Kimmel and Veil, 2009). The Tennessee Valley Authority (TVA) Gallatin Fossil Plant is not permitted to discharge water used for cooling back into the Cumberland River due to thermal pollution (water > 90 F) (WSMV Nashville 2007; Kimmel and Veil, 2009; NETL 2009c).  Nuclear and coal-fired plants within the TVA system were forced to shut down some reactors (e.g., the Browns Ferry facility in August 2007) and curtail operations at others. This problem has not been limited to the 2007 drought in the southeastern United States. A similar situation occurred in August 2006 along the Mississippi River (Exelon Quad Cities Illinois plant).  Other plants in Illinois and some in Minnesota were also affected (Union of Concerned Scientists 2007). The production of gas from oil shale and biofuels has exacerbated the issues in the Plains states (Kansas, Oklahoma, Texas), Upper Rocky Mountains, and the Ohio River Valley (Hightower, 2009; Kimmel and Veil, 2009).  DOE (2006) specifically identifies where new power plants have been opposed because of potential negative impacts on water supplies (Tucson Citizen, 2002; Reno-Gazette Journal, 2005; U.S. Water News Online, 2002 and 2003; Curlee, 2003). Recent droughts and emerging limitations of water resources have many states, including Texas, South Dakota, Wisconsin, and Tennessee, scrambling to develop water use priorities for different water use sectors (Clean Air Task Force, 2004a; Milwaukee Journal Sentinel, 2005; GAO, 2003; Curlee, 2003; Hoffman, 2004; U.S. Water News Online, 2003)

So what is currently happening?  Current legislation  is mostly silent on the power-water nexus.  This is not to say that little is being done. A number of federal agencies are actively involved with the power-water nexus, including DOE, via NETL, and NREL, NOAA, USEPA via water Wise and Energy Star, BLM though management of land and water resources in the west, USDA and Department of the Interior/USGS which inventories water supplies.  However, DOE (2006) noted that collaboration on energy and water resource planning is needed among federal, regional, and state agencies as well as with industry and other stakeholders.  GAO (2012a) notes that the growth in water and energy demands is occurring at a time when the nation’s supplies are stressed by a growing population, a variety of new and changing uses, and environmental challenges such as climate change, but none of the involved agencies consistently or strategically collaborate on to ensure a harmonized approach to energy and water resource planning.

Effective integrated energy and water policy planning will require identifying the individual and cumulative impacts that power plants have on water resources and the vulnerabilities of specific power plants to changes in water resources (Wilkinson 2007, Scott and Pasqualetti 2010;Stillwell et al 2011; Kenney and Wilkinson 2012). From a systems perspective, a sustainable society is one that has in place the institutional, social and informational mechanisms to keep in check the feedback loops that cause exponential population growth and natural capital depletion.  A sustainable world is not a rigid one, where population or productivity is held constant.  Yet sustainability does require rules, laws and social constraints that are recognized and adhered to by all (Meadows, 2005).   Integrated planning implies removing silos, working collaboratively, and using resources wisely. It implies using the combined intelligence of multiple parties in the planning and fulfillment of goals. It implies linking a vision, priorities, people, and institutions into a flexible system of evaluation and decision-making.  In other words, leadership.
