When you prepare the Thanksgiving meal, do you ask each person to make a dish of their choosing, with no coordination for an overall cohesive meal? Probably not. Most likely, you plan, because you want everything to fit together.
Now imagine a water utility with different departments like water quality, finance, and administration. Most water utilities have high energy costs, so each department needs to manage and reduce its energy use – but typically there’s no plan to synchronize these efforts. With such a piecemeal approach, the utility may get overall energy savings, but it’s not maximizing the potential to meet ambitious efficiency goals or reduce power costs.
Enter the Energy Management Plan (EMP), a tool that sets up an organization-wide strategy for energy use. By creating a coordinated vision, an EMP establishes clear efficiency goals and gives departments the flexibility and direction for meeting them. That’s what this summer’s EDF Climate Corps fellow focused on at Tarrant Regional Water District (TRWD), which supplies water to 2 million users in the Fort Worth area. The TRWD fellow found opportunities where an EMP could improve the utility’s energy efficiency and management, leading to potential savings and less wasted water. Read More

Have you ever thought about how much water your dryer needs to dry your clothes? (And no, I don’t mean your washing machine.)
Every appliance in your home has a water intensity, or the amount of water needed to make and send the electricity that powers it. On the flip side, all water – like in your faucet, toilet, and irrigation system – has an energy intensity, the amount of electricity needed to treat, distribute, or heat the water. Chances are, you probably haven’t given much consideration to the water intensity of your home energy, or the energy intensity of your water. There hasn’t been any data at the household level – until now.
Environmental Defense Fund (EDF) recently teamed up with Pecan Street, Inc. to examine these combined metrics in a new study. Pecan Street, a research group running the most extensive energy-tracking in U.S. history, analyzed the energy and water costs of a group of Austin homes and their appliances.
By gathering granular data on how much energy and water households use, as well as their associated energy and water intensities, this study reinforces the need for smart technology to help us better understand and manage energy and water. Moreover, in order to safeguard water supplies, the analysis demonstrates the importance of powering our lives with low-water clean energy resources. Read More

This 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
Olympic 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.
Austin, 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).

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.
