New Study: Solar, Energy Efficiency Can Help the Texas National Guard Save Money and Water

HeroBannerMain24 croppedThis year has seen historic flooding across the South. In addition to the devastating rains that recently hit Louisiana, severe floods pummeled Texas earlier this year. In both cases, the states’ National Guards were first responders, rescuing families, delivering meals and supplies to survivors, and providing local agencies with high-water trucks, boats, and helicopters.

As the frequency of extreme weather events like these increases, it is imperative that the National Guard can continue devoting resources to critical, first-responder services. But in Texas, those services could be threatened by the state’s dwindling water supplies.

A new study from CNA Analysis & Solutions, funded by Environmental Defense Fund and in collaboration with the Texas Army National Guard (TXARNG), shows many Texas defense facilities are in water-stressed counties. Over time, this could result not only in higher water costs, but also power production constraints, since it requires a lot of water to produce and move electricity from traditional energy sources like coal and natural gas. Both of these challenges pose a direct threat to the budget and operating capabilities of the TXARNG. Fortunately, the analysis also indicates these same areas have great potential for solar energy, which requires little to no water to meet power needs on-site.

By tapping into that potential and pursuing bolder energy efficiency initiatives, TXARNG could ease pressure on the electric grid and reduce utility bills, all while safeguarding residents and precious water supplies. Read More »

Going for the Green: Rio Olympics Show Link between Environment, Economy, Health

OlympicHandOlympic Games are historically about gold, silver, and bronze – not green. Even the “greenest” Olympics, held in London in 2012, used nearly 400 temporary generators, which release harmful pollution, including carbon monoxide and nitrogen oxides among many others. Nevertheless, when Brazil won its bid in 2009 to host the 2016 Olympics in Rio de Janeiro, the country pledged to host the "Green Games for a Blue Planet,” a festival with sustainability at its core.

Brazil, nearly as large as the U.S. and holding 60 percent of the Amazon rainforest, currently uses renewable energy to make about 85 percent of its electricity (compare that to the U.S., where only 13 percent of our electricity comes from renewable sources). With renewable energy success like that, who better to host the “Green Games?”

Yet, despite Brazil’s ambitious goals, years of planning, and an advantage in existing renewable energy resources, Brazil is falling short of its goal for a cleaner, greener Olympics. This is because serious social, political, environmental, and health challenges tangent to the Olympics have constrained the nation’s ability to realize the sustainability goals Brazil thought achievable in 2009.

3 Sure Signs of Texas’ Emerging Solar Market

solar flickr ricketyusAustin, my home for the past 35 years, is typically a pretty sunny place year-round. But summer is when I am reminded of the sun’s unwavering presence and strength.

Fortunately, Texas is beginning to put those rays to work, as evidenced by GTM Research and the Solar Energy Industries Association’s (SEIA) newest U.S. Solar Market Insight. Along with projected scenarios from the state’s main grid operator and a recent poll of Texas voters, the report confirms the Lone Star State’s solar power is on an unstoppable course. And the more we can take advantage of the sun’s energy, the less we have to rely on outdated, polluting coal plants – a good thing for our health and water.

Here are three reasons Texas solar is on the rise:

  • Texas solar is growing very quickly: The new Solar Market Insight report declares Texas to be the fastest growing utility-scale solar market in the country. In fact, by the end of 2016, SEIA predicts the state’s total installed solar capacity will more than double. And within the next five years, Texas’ solar market will be second only to California’s (although, considering California has one-fourth of the solar power potential of Texas, we could eclipse the Golden State in coming years).

On the Front Lines: Climate Action from Agriculture Can Help Defend a Texan Way of Life

longhorn-cattle-pixabayBy: Simone Ballard, energy-water nexus intern

Growing up in a rural community in Illinois, agriculture was a part of my everyday reality. My neighbors took pride in their livestock and centennial family farms. It wasn’t just a job for them, but a way of life. Sustaining farms and ranches is still a livelihood for millions of people in this country, putting food on our tables and fueling our economy. This traditional lifestyle is celebrated here in Texas too, but now it faces a unique challenge and opportunity presented by a shifting climate.

So, following the recent historic climate agreement in Paris, now is the time for agriculture to take a prominent role alongside other sectors in leading emission reductions worldwide. Why? The security of our food supply is at stake. The opening remarks of Paris’ COP21 Conference outline the reasons we must take action to mitigate the impacts of a changing climate: …safeguarding food security and ending hunger, and the particular vulnerabilities of food production systems to the adverse impacts of climate change.”

Climate change will impact every facet of human society, so it is critical that diverse groups like agriculture, industry, and municipal contribute new solutions to solving our growing emissions problem. Sometimes those of us who now live in cities – and that’s over half the human population worldwide – forget about agriculture’s critical and tangible role at the beginning of the discussion. However, that narrative is shifting in this pivotal moment of climate discussions, as shown in the above statement.

In Texas, where agriculture makes up a large part of our economy, we should be thinking creatively about how to reduce emissions alongside other major players, like energy industry innovators. If we want to protect our natural resources, keep our communities thriving, and create a healthy environment for many generations to come, we need each sector to play its part and act on climate.

Texas’ Evolving Energy Reality: Clean Energy Uses Less Water

wind water flickrIt’s been an interesting time for water in Texas. Beyond the incredibly wet and cool spring we’ve been having, Memorial Day saw the second year in a row of record-breaking floods.

And a few weeks ago, the Texas Water Development Board (TWDB) asked for comments on the draft 2017 State Water Plan. The TWDB is the state agency responsible for water planning, and every five years it produces a strategy that “addresses the needs of all water user groups in the state – municipal, irrigation, manufacturing, livestock, mining, and steam-electric power.”

In the five years since the last state water plan, Texas has gone from one extreme to the other in terms of water: from the throes of a devastating drought to historic flooding that resulted in some reservoirs being full for the first time in 15 years.

In this climate of feast or famine, we need to better understand our water supplies and conservation efforts, both of which have a strong tie to our energy choices. That’s why Environmental Defense Fund (EDF) weighed in on Texas’ draft water plan. Not only does the state significantly overestimate the amount of water needed to make electricity, but a more comprehensive view of energy in relation to water demand and supply would benefit the 2017 State Water Plan and future plans.

Forget Taco Wars – the Real Competition is Over Who is Using Water More Wisely

Guadalupe_river_Hunt_TXSan Antonio and Austin just called a cease-fire on a taco war over which city invented the breakfast taco. Both make excellent tacos: from the traditional chorizo and egg taco in San Antonio to a free-range egg and organic spinach taco in Austin. But this debate was about more than just tacos – it was about the history and culture of these two neighboring cities.

Only 80 miles apart, San Antonio and Austin have some significant differences. San Antonio is known as “Military City USA” largely due to its huge military bases, but it’s also known for other industries like biotech, military medical centers, and a dynamic business relationship with Mexico. The capital city’s economy, on the other hand, is based on high-tech, entertainment, state government, and the behemoth University of Texas at Austin. San Antonio is one of the largest Hispanic-majority cities in the country (at 63 percent in 2010), while Austin’s diversity comes in large part from people flocking to the Capitol from all over the state and country. As someone with roots in both San Antonio and Austin, I appreciate both – I’m an equal opportunity taco lover.

But both cities share an important commonality: exploding population growth. The population of the 13 counties that make up the Austin-San Antonio corridor is estimated to increase by 77 percent by 2050, to 6.8 million people. Extreme growth brings intense pressure on resources and services, particularly water in this drought-prone region. Both cities are standing up to that challenge through careful water conservation measures and by advancing clean energy. Read More »
