Energy-Water Nexus Spans Across Western United States

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

By Kate Zerrenner / Published: August 8, 2013

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.

New Warnings About Methane Emissions

By Steven Hamburg / Published: August 5, 2013

Concerns about the methane problem associated with the U.S. natural gas boom are mounting with each study released. This week scientists with the National Oceanic and Atmospheric Administration (NOAA) and the University of Colorado (UC) at Boulder published a new paper on methane leakage in the journal Geophysical Research Letters. It reports an alarmingly high level of methane emissions in the Uintah Basin of Utah — 6.2 to 11.7 percent of total production for an area about 1,000 square miles. Findings are based on readings from airplane flights that measured methane in the air on a single day and estimated the proportion of those emissions that came from the oil and gas infrastructure —production, gathering systems, processing and transmission of the gas out of the region. The authors calculated the uncertainty of their measurements, finding a 68 percent chance the leak rate is between 6.2 and 11.7 percent, and a 95 percent chance it is between 3.5 and 14 percent.

This follows two other regional studies conducted by scientists at the same organizations. One released last May in the Journal of Geophysical Research reported a 17 percent methane leak rate for the Los Angeles Basin, which has received quite a bit of attention although, as I’ll explain below, the figure can be misleading.  The second study, conducted over the Denver-Julesburg Basin in 2008, found 4 percent of the methane produced at an oil and gas field near Denver at that time was escaping into the atmosphere. Taken together, these studies are troubling. They should be regarded as alarm bells ringing in our ears. Action by policymakers and industry is needed now.

Any amount of methane lost from the natural gas supply chain should be eliminated whenever possible. That’s because methane retains heat much more effectively relative to carbon dioxide: Over the first 20 years, an ounce of methane traps in heat 72 times more efficiently. Even small amounts vented or released as “fugitives” – unintentional methane leaked as gas moves from the field to your doorstep – can reduce or eliminate the climate advantage we think we’re getting when we substitute natural gas for coal or oil.

Maryland’s Governor O’Malley Leads The Way On Climate And Clean Energy Policy

By John Finnigan / Published: July 29, 2013

John FinniganMaryland Governor Martin O’Malley continues to lead the way on climate and clean energy policy.  On Thursday, he unveiled Maryland’s new Greenhouse Gas Emissions Reduction Act (GGRA) Plan.  Gov. O’Malley’s plan raises the targets for renewable energy, energy efficiency and peak energy demand reduction, while re-affirming Maryland’s membership in the Northeast Regional Greenhouse Gas Initiative (RGGI).  The plan adds new climate programs relating to transportation and forestry, and a new aspirational goal to make Maryland a zero-waste state.

Maryland is particularly vulnerable to climate change with 3,000 miles of shoreline along scenic Chesapeake Bay.  The state ranks 42nd in total area, but 10th in coastline area.  Gov. O’Malley has addressed climate change since his early days in office.  In 2007, he established the Maryland Climate Change Commission to address the causes and effects of climate change in Maryland and develop an action plan.  The Maryland Climate Action Plan (Plan) was issued in August 2008, and Gov. O’Malley has labored diligently to implement the plan since that time.

The new Plan  calls for increasing the renewable energy portfolio standard from 20% to 25% by 2022, as well as the energy efficiency and peak demand reduction targets (with the new, higher targets to be announced at a later date).  Like a true leader, Gov. O’Malley aims high and is unafraid to be different.  His call to raise these clean energy standards comes at a time when some states have been unsuccessfully pressured by the fossil-fuel industry to consider lowering their clean energy standards.

America’s Aging Energy Infrastructure Needs An Overhaul

By Jim Marston / Published: July 19, 2013

No one likes being told “I told you so.”  But since DOE released its report last week, I’ve been tempted.

The report warns that the existing American energy infrastructure is highly vulnerable to climate change.  That increasing temperatures will stress the U.S. water system and enhance the likelihood of drought. That because conventional power plants require huge volumes of water to operate, lower water availability will mean less reliable power.  And that the changing climate will prompt more extreme and frequent storms, increasing energy demand due to extreme temperature changes and threatening our aging and already stressed electric grid with potential blackouts.

In essence, the affirms the many the calls-to-action that EDF and many other groups have been leading for years and the lessons we learned from Superstorm Sandy made painfully real and salient:  Our existing energy technologies and policies were designed for a 20th century climate.  To weather the extremes of a 21st century climate, we need to a 21st century energy system – one  that promotes energy efficiency, enables widespread adoption of homegrown, renewable sources of power and allows people to control their own energy use and reduce their electricity costs.

I have been very encouraged by President Obama’s recent movement on climate change, and the DOE report provides research backing the urgency of his Climate Action Plan.  Hopefully, this recent movement will translate into real national momentum, as our national approach to energy truly needs an overhaul.

States Stand Up To ALEC’s Assault On Renewable Energy: Clean Energy – 26 ALEC – O

By Marita Mirzatuny / Published: July 18, 2013

Back in March, I wrote about the American Legislative Exchange Council’s (ALEC’s) state-by-state attack on renewable energy. The attacks contribute to ALEC’s growing reputation as a “shadowy right-wing front group,” funded by the likes of Koch Industries, ExxonMobil and Peabody Energy, the largest private-sector coal company in the world. ALEC’s legislative efforts were aided by the Heartland Institute, a “free-market think tank” and notorious climate change denier.

ALEC has a clear motive: to serve the interests of dirty fossil fuel power plants and block progress towards greater use of clean, homegrown energy.

I’m happy to announce that ALEC and the Heartland Institute’s efforts to roll-back individual state’s renewable energy goals decisively failed in legislatures spanning from West Virginia to Kansas. In total, 26 bills designed to remove renewable energy standards (RPS) for eight states were denied, according to a report from Colorado State University’s Center for the New Energy Economy.

Now, Kansas, Missouri, Ohio, North Carolina, Texas, West Virginia and Wisconsin will continue on the path towards a clean energy future. Even better, some states increased their energy guidelines, namely Colorado, Connecticut, Maryland and Minnesota.

This news comes as a resounding victory for the climate, consumers, and Americans who care to see the U.S. progress into the global $ 2 billion clean energy economy. Read More »
