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.

Energy-Water Nexus Spans Across Western United States

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

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 »

Why Luminant Shouldn’t Get a Free Pass to Pollute

Yesterday, Luminant filed a motion in the DC circuit court to fight vital clean air rules that other utilities in Texas have been able to meet. Instead of working with EPA on a path toward cleaner air, Luminant abandoned recent talks with EPA and issued a press release that recused itself of responsibility, threatened possible plant closures and blamed EPA for potential job losses. Luminant's recent statement highlights a simple fact: closing plants is a business decision, plain and simple. Luminant isn’t closing these plants because of EPA regulations – that’s just their cover story.  They’re closing the plants because they did not begin to make reductions to meet the rule that anyone could see was coming.  The EPA just gives them a convenient way to shift blame. Moreover, Luminant is ignoring other viable alternatives to plant closures just to save some money in the short-term.  If anyone loses their job, they can blame Luminant’s management team for failing to plan accordingly to abide by the law.  We feel very bad for the workers whose company let them down.
