Benefits of Clean Power Plan Are Measureable – Drop for Drop

Hallisburg Texas power plantSince EPA released its proposed Clean Power Plan (CPP) in June of this year, the plan has been a hot topic in every state. In Texas alone, the state has held a joint regulatory agency hearing and two days of legislative hearings. Unfortunately, in both cases, the general tone of testimony was that of Chicken Little. But I prefer to view the CPP as a fantastic opportunity and certainly don’t think the sky will fall because of it. In fact, our skies should be considerably brighter without all that carbon pollution clouding them up.

I’ve written before about the opportunity for Texas to amplify current trends and increase our energy efficiency and renewable energy to meet these goals. And there’s an added benefit to transitioning away from coal-fired power plants and toward cleaner energy choices, one that will be critical in a state like Texas that’s in the middle of a multi-year drought: water savings and relief for our parched state.

What if I told you that with the CPP, the Electric Reliability Council of Texas (ERCOT), which controls the power grid for roughly 80 percent of the state, could save more than 60,000 acre-feet (or nearly 21 billion gallons) of water per year by 2030? Read More »

Sprung a Leak? Smart Water Meters to the Rescue

Source: freshserviceinc.com

A few months ago I logged into my online utility account and noticed it was more than twice the amount I usually pay, all of the excess going to water. Given the kind of work I do, I scour my bill every month, comparing electric and water usage month-to-month and over the course of the year. We are water and electricity savers in our household, so what on earth could this spike be?

I immediately called the City of Austin, and they sent someone out to check the meter. Nope, nothing on that end. Then we brought in a plumber, who spent many hours and many of our dollars searching and found a leak in the toilet. By the time we went through all of that and got the toilet fixed, we had to pay our enormous bill plus the plumber’s bill. Why should I have to go through that rigmarole just to find a leak?

Wouldn’t it be easier if a smart water meter could send my utility and me a message the moment the toilet starts leaking?

Unfortunately, water infrastructure in this country is sorely in need of a reboot. The American Society for Civil Engineers gave the U.S. drinking water infrastructure a grade of a “D” in its 2013 Report Card for America’s Infrastructure, stating there are 240,000 water main breaks per year. And we’re still using antiquated “technology” in much of the sector. Read More »

The First US City to Run Out of Water?

By: Rachel Finan, student at the Johns Hopkins University School of Advanced International Studies

Rachel Finan

Experts predict that by 2025 Sana’a, Yemen will become the first capital city to run out of water. They predict that by 2030 India will need to double its water-generation capacity or face the same fate, and water supplies in Istanbul, one of the world’s largest cities, is at just 28 percent. Yet before any of those cities run dry (in far off developing countries that most people in the US associate with water scarcity issues), it could be a US city that runs out of water. And it’s not just the usual suspects in the Southwest who face increasingly serious water concerns. Miami, FL is the second-most vulnerable US city in a drought according to a University of Florida Environmental Hydrology Laboratory study. Cities such as Cleveland, OH; Chicago, IL; and New York, NY follow not far behind.

Just last February, California state officials announced that 17 communities and water districts could run out of water in as little as 100 days. In Texas, that number more than doubles. Earlier this year state officials reported 48 communities were within 90 days of water interruptions; as of August 20th, there are 27 communities on that list. One small town in TX reportedly already has run dry.

This begs an obvious question; what are we doing about it? Additionally, what should we be doing about it – not just as a temporary fix, but as a long-term, strategic response? What would you do if water stopped coming out of your tap? Imagine if your town was one of the California or Texas communities with only 90 days of water left. As an EDF Climate Corps fellow, I’ve spent the last several weeks contemplating these questions and identifying opportunities for Texas-based institutions to not only conserve water, but to save money while doing so. I’ve been inspired by many examples throughout the state. Read More »

Estimates do not Meet Reality, Time to Improve Texas Water Planning

Recently, the Texas Center for Policy Studies (TCPS) issued its report examining Texas’ current water planning process. Founded in 1982, TCPS has pursed its theme of "Research for Community Action" by developing policy recommendations for sustainable growth and development in Texas.

Water has been a major topic for this work, and the current drought highlights the need for an effective state water planning process. TCPS’s report, however, finds fault with many aspects of the current planning process.

Overall, the report concludes that the projected need for water in 2060, according to the Texas Water Development Board (TWDB), is more than twice the amount that should be needed. As a result, the 2012 State Water Plan, developed by TWDB, recommends spending many billions of dollars on new reservoirs and other water projects that can be avoided. Read More »

Desalination can Help Solve our Water Woes, but not without Clean Energy

Source: Prodes Project

As drought continues to grip Texas and many other Western states, one of the solutions often discussed (and pursued) to overcome water scarcity is desalination. Simply put, desalination, or desal as it is most commonly called, is a process that removes salt and other minerals from salty (brackish) or seawater to produce freshwater for drinking and agriculture. This technology seems like a no-brainer option for addressing the state’s water woes, but the problem is that desalination uses a lot of electricity and the majority of Texas’ electricity comes from coal and gas power plants, which require copious amounts of water to generate that electricity. It doesn’t make much sense to use water to make water, especially when there’s an alternative in Texas’ abundant renewable energy resources.

Texas is the national leader in wind energy and has the greatest solar energy potential in the U.S., yet neither of these resources are being widely deployed for desal plants despite recent studies pointing to vast opportunities. Not only do these energy resources produce negligible carbon emissions, but they also consume little to no water, unlike fossil-fueled power plants. Furthermore, if we look at where brackish water sources are located compared to where the wind and solar energy potential is in this state, the overlap is pretty clear. This synergy should not be ignored.  Read More »

Early this week, the White House released the third National Climate Assessment (NCA). What’s the main take away? That Americans are already feeling the effects of climate change.

The NCA, authored by 300 experts and guided by a 60-member Federal Advisory Committee, analyzes the best available data in the U.S. on the observed and future impacts of climate change, and organizes its findings for specific sectors and regions. Texas falls under the Great Plains region and the state’s bustling economy includes many industries that will be affected by a changing climate, such as agriculture and energy.  Our water, ecosystems, transportation, and more will also be affected. It is clear from this report that heat and drought will intensify in Texas, putting energy, agriculture, and human health at increased risk. State leaders need to enact policies now to protect us and our livelihoods.  Read More »

Showtime Brings Realities of Texas Drought Home to Millions

It may seem like only yesterday that Texans were asked to conserve water after another scorching summer, but in reality it was four, dry years ago. The drought, which began in 2010 after La Niña altered sea level temperatures in the Pacific, continues to persist in the Lone Star State and promises to surpass the state’s record-setting multi-year drought from the 1950s. Ranchers have been forced to sell off cattle, town water supplies continue to go dry, and power plants struggle to provide a reliable supply of electricity due to water scarcity and long stretches of hot weather. Given these bleak conditions, it should not come as a surprise that 70 percent of Texans believe global warming is happening—and 52 percent said they have personally experienced the effects of global warming.

An all-star team of producers, including James Cameron, Jerry Weintraub and Arnold Schwarzenegger, intends to bring the Texas drought home to millions of televisions across the nation in the Years of Living Dangerously series premiering Sunday. Through this series, a host of celebrities, activists and journalists share the stories of those impacted most by our changing climate and what’s being done to save our planet. What is clear right now, in Texas and beyond, is that as climate change intensifies, we must adapt to more extreme weather conditions and make resilient changes that mitigate further stress.

Energy-Water Nexus Around the World and the Missing Link

IEA blog

As we have highlighted before, Texas is experiencing significant population growth, adding around 1,000 people a week to the state, which increases the need for both water and electricity. The US Energy Information Administration estimates that electricity demand in this region will increase by more than 30% by 2035, yet, like many states in water-strained areas, it is not taking full advantage of new policies to address the energy-water nexus, such as increased use of solar PV, wind and energy efficiency. 

The energy-water nexus is gaining traction with diverse stakeholders around the world and it is becoming increasingly clear that we cannot plan for our planet’s future if we do not consider energy and water together.

Most recently, the United Nations celebrated World Water Day, launching a yearlong effort to highlight the global energy-water nexus, the chosen theme for 2014. In honor of World Water Day, the International Energy Agency (IEA) released its annual World Energy Outlook report, the first analysis of its kind to look at the impacts of water scarcity on the global energy sector. This signals a big step in the global understanding of the importance of the energy-water nexus, and reveals important insights on how regions, nations, and industries must cope with less water in a changing climate.

Is Texas the Next Global Leader in Water? It’s Up to State Leaders to Decide.

Source: WATR News

Source: WATR News

The Texas Comptroller, Susan Combs, recently released the Texas Water Report: Going Deeper for the Solution, which proposes a sort of revolution to solve Texas’ water woes. As Combs notes, Texas is a global energy leader, but the state should be a global water leader too. And her initiative couldn’t come fast enough. Texas, already prone to cycles of drought, is facing new water pressures, including population growth and a changing economy, which only make it harder to preserve our diminishing water supply. To rouse the state’s water recovery plan, the report prioritizes water-saving technological innovations (while stressing the need for conservation) and lauds various Texas cities for water management practices. But the report misses some key elements that are essential to keeping our water flowing. In the same way that new energy technologies have brought us closer to a cleaner, more reliable electric grid, innovations in the water arena can seamlessly reduce our water use and set the state on a sustainable path.

The report says conservation is not enough, and it’s right. However, efficiency is the most significant first step and conservation achieved through technology is a welcome counter to the infrastructure-heavy plans typically heard at the Capitol and in the State Water Plan. (What good is a new reservoir, if there’s no water to put in it?) Some of the technologies evaluated in the report include aquifer storage and recovery, inter-basin transfers, low-water fracking technologies and desalinization – what some call “game changers.” These technologies could potentially relieve our future water woes, but these projects are expensive and don’t alleviate our immediate or even mid-term water stresses.

Energy And Water Utilities’ Unique Perspectives Uncover Joint Cost-Saving Solutions

This commentary originally appeared on EDF's Energy Exchange blog.

In the past, I’ve written a lot about the inherent connection between energy and water use and the need for co-management of energy-water planning. Most of the energy we use requires copious amounts of water to produce, and most of the water we use requires a considerable amount of energy to treat and transport. Despite this inherent connection, it’s actually uncommon to see energy and water utilities collaborating to identify best practices to save energy and water and even lower costs. Think of it this way: If energy and water utilities worked together, their unique perspectives could uncover joint cost-saving solutions, customers would save more money and utilities could share data to better understand their holistic energy-water footprint.

Identifying why there is a lack of collaboration and how to overcome these barriers was the motivation behind the American Council for an Energy-Efficient Economy’s (ACEEE’s) recent report.  The report goes beyond citing discrepancies, though, and provides solutions for energy and water utilities to create better, more resource-efficient programs for themselves and their customers.

The report highlights a number of ways U.S. energy and water utilities have collaborated to identify mutually-beneficial energy and water savings. It lists successful energy and water utility programs from a variety of different sectors, including residential, commercial, industrial, agricultural and municipal. Read More »
