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.

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

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.

We Can't Expect a Reliable Energy Future Without Talking Water

Kate Zerrenner

This commentary originally appeared on our EDF Voices blog.

It’s no secret that electricity generation requires substantial amounts of water, and different energy sources require varying amounts of water. Nor is it a surprise that Texas and other areas in the West and Southwest are in the midst of a persistent drought. Given these realities, it is surprising that water scarcity is largely absent from the debate over which energy sources are going to be the most reliable in our energy future.

Recent media coverage has been quick to pin the challenge of reliability as one that only applies to renewables. The logic goes something like this: if the sun doesn’t shine or the wind doesn’t blow, we won’t have electricity, making these energy sources unreliable. But if we don’t have reliable access to abundant water resources to produce, move and manage energy that comes from water-intensive energy resources like fossil fuels, this argument against the intermittency of renewables becomes moot.

Moving forward into an uncertain energy future, the water intensity of a particular electricity source should be taken into consideration as a matter of course.  Read More »

Texas Congressman Denies Climate Change While Texans Seek More Action On Global Warming

Sunflower solar panels, Austin TX

Last week, San Antonio Congressman Lamar Smith took a break from Washington’s budget battles to weigh in on the latest assessment report from the Intergovernmental Panel on Climate Change (IPCC). In his Texas Weekly guest column, Congressman Smith cast doubt on the link between global warming and extreme weather and criticized efforts to curb greenhouse gas emissions (GHGs), cherry-picking passages of the report to support his own arguments.

Let’s look at what the report really says. Based on mountains of evidence and an unprecedented scientific consensus from hundreds of the world’s best climate scientists, the IPCC finds that “warming of the climate system is unequivocal,” and “human influence on the climate system is clear.” Furthermore, the report settles that human influence has very likely affected frequency and intensity of daily temperature extremes and likely doubled the probability of heat waves. The report further predicts that extreme heat will only get worse from here, concluding it is very likely that heat waves will occur with a higher frequency and duration in the future. Sounds like extreme weather to me.

When you contrast these findings with Texas’ recent streak of scorching summers, it’s easy to understand why a majority of Texans say they have personally experienced the effects of global warming. Extreme temperatures, since 2010, have helped plunge the state into a historic, multi-year drought, which is expected to be the new norm. Both the National Oceanic and Atmospheric Administration (NOAA) and independent climate scientists, including Texas A&M’s atmospheric sciences department, have attributed Texas’ historic 2011 heat wave and drought primarily to climate change.

A Future Of Hotter Summers Will Stress Energy And Water In Texas

With Labor Day behind us, Texans can look forward to a welcome respite from the hundred-degree days of August. The pending arrival of fall may signal milder temperatures for now, but the latest report from John Nielson-Gammon, Texas’ state climatologist, tells a different story about Texas’ long-term climate trend. The study released last month indicates that peak summer temperatures may increase by up to five degrees by 2060. What we once thought of as a unique heat wave (think back to 2011) are likely to become the new normal, and will eventually – according to Nielson-Gammon – be replaced by even hotter temperatures.

At the same time, increasing temperatures would place further severe stress on the state’s energy and water systems. Texas’ recent extreme summers have already plunged much of the state into drought. The latest data released by the U.S. Drought Monitor predict water emergencies could occur in at least nine U.S. cities—five of which are in Texas. And experts expect the drought will persist for years to come as climate change intensifies.

Texas lawmakers must take these grim projections into account as they plan the state’s energy and water futures. Some Texas decision makers are already calling for more fossil-fuel power plants to cover the need for more power (to run all those air conditioners) in light of 2011’s historic summer highs, which will emit more carbon pollution into the air and add to the warming. These same Texas lawmakers insist we should keep our heads in the sand, ignore the mounting evidence pointing to a new climate normal and do nothing to alleviate or adapt to the problem. Read More »

Local Energy-Water Solutions Should Be A Model For The Nation

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

Over the past several weeks, I've written a lot about the intimate and inextricable connection between energy and water. The energy-water nexus involves a number of technologies, environmental factors and stakeholders. Thus, it’s no surprise that water and energy’s fundamental connection has eluded policymakers for so long. With this post, I review the lessons discussed so far, so that policymakers can understand the key issues surrounding the energy-water nexus and what’s at stake if we fail to act now.

The Bottom Line

Conventional electricity sources, like coal, natural gas and nuclear power plants, require an abundance of water — about 190 billion gallons per day. Because the majority of our electricity comes from these sources, high energy use strains the water system and contributes to Texas’ prolonged drought. Coincidentally, extreme drought could force power plants to shut down.

Climate change is having a profound effect on our weather patterns, making extreme heat and drought more common in Texas and throughout the Southwest. If we don’t set the energy-water system on a sustainable course, we risk a compounded problem.

NOAA Reports On Climate; Texas Politicians Stick Heads In Sand

This post originally appeared on EDF's Voices blog.

Last week, a coalition of environmental groups presented U.S. Senator Ted Cruz and other Texas politicians with “awards” for their persistent denial of basic climate science. In fact, climate change denial is all too common among Texas lawmakers. Governor Rick Perry, for example, calls climate change “a theory that has not been proven.”

In contrast, the international scientific community almost unanimously agrees that greenhouse gases associated with human activity are responsible for the global warming pattern we’ve seen since the mid-20 century. Earlier this month, the National Oceanic and Atmospheric Administration (NOAA) released its annual State of the Climate report. The report brings together leading scientists and academics to assess the state of the Earth’s climate. The 2012 report, which included contributions from 384 authors from 52 countries, is the most authoritative analysis of climate change and its global effects. Read More »

Energy-Water Nexus Spans Across Western United States

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

Source: feww.wordpress.com

Over the past few weeks, I’ve written a number of posts to help shed light on the fundamental connection between energy and water. Because many of our energy sources gulp down huge volumes of water, it’s imperative that we break down the long-standing division between energy and water planning — especially in drought-prone states like Texas. I’d like to take a step back and look at how Texas’ neighbors are addressing energy and water co-management. While Texas may be an extreme example, looking toward its immediate neighbors could provide ideas and best practices to improve the state’s situation.

A number of western states are facing many of the same challenges as Texas. Electricity production is a major drain on the region’s water supply. A study co-authored by Western Resource Advocates and EDF showed that thermoelectric power plants, such as coal, natural gas and nuclear, in Arizona, Colorado, New Mexico, Nevada and Utah consumed an estimated 292 million gallons of water each day in 2005 — roughly equal to the amount of water consumed by Denver, Phoenix and Albuquerque combined (and we’re talking water consumption, not just withdrawals). Like Texas, the western states face a future of prolonged drought. Scientific models predict climate change will increase drought throughout the Southwest, placing greater stress on the region’s delicate water supply.

Additionally, electricity production, numerous thirsty cities and widespread agricultural activity all strain the water system, too. Because so many flock to western states for fishing, kayaking, rafting and other recreational water activities, setting the region’s water system on a sustainable path is a critical economic issue. The exceptional challenges facing western states have already prompted some states to consider the energy-water nexus when planning to meet future water and electricity needs. Read More »

Energy And Water Are Running Out In Texas, But It’s Not Too Late

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

As we’ve highlighted in previous posts, water and energy regulators often make decisions in silos, despite the inherent connection between these two sectors. Texas is no exception.

Two very important and intertwined events are happening in Texas right now.

First, the state is in the midst of an energy crunch brought on by a dysfunctional electricity market, drought, population growth and extreme summer temperatures. An energy crunch signifies that the available supply of power barely exceeds the projected need (or demand) for electricity. Texas’ insufficient power supply makes the whole electricity system vulnerable to extreme weather events. An especially hot day (with thousands of air conditioning units running at full blast) could push the state over the edge and force the Electric Reliability Council of Texas (ERCOT), the institution charged with ensuring grid reliability, to issue rolling blackouts.

Second, Texas is still in the midst of a severe, multi-year drought, forcing state agencies to impose strict water restrictions throughout the state. The drought has already had a devastating impact on surface water and many communities are facing critical water shortages.

Although Texas has always had to deal with extreme weather events, we can anticipate even more intense weather as climate change advances. The new climate ‘normal’ makes extreme heat waves, like the historic 2011 Texas summer, 20 times more likely to occur. These extreme weather events heighten the urgency of the energy-water nexus.

Where Is All Of The Water Going? A Look At Which Energy Resources Are Gulping Down Our Water

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

If you’re like so many conscientious consumers, you’ve experienced the disappointment that comes when you realize the lean turkey breast you bought has 300% of your daily value of sodium, negating the benefits of its high-protein and low-fat content.  Instantly, food choices feel more complex; you’ve learned the hard way that the pursuit of a low-fat diet is not the same as a healthy diet.

The Energy-Water Nexus shows us that our energy choices are much like our food choices: The environmental benefits of an energy diet low in carbon emissions might be diminished by increased water consumption (or waste), and the unforeseen tradeoffs between the two resources (i.e. more sodium in lieu of less fat, can hurt us in the long run).

Water Intensity

As we have mentioned before, roughly 90% of the energy we use today comes from nuclear or fossil fuel power plants, which require 190 billion gallons of water per day, or 39% of all U.S. freshwater withdrawals (water “withdrawal” indicates the water withdrawn from ground level water sources; not to be confused with “consumption,” which indicates the amount of water lost to evaporation.)
