What would a world powered by clean, low-water energy look like? If you visit Israel’s southern region, you don’t have to imagine.
In 2011, Arava Power in the southern Israeli desert launched a 4.9 MW solar field (enough to power more than 3,000 U.S. homes). Since then nearly 200 times as much capacity – both fields and rooftops – has been installed in the region. By 2025, it’s likely solar will provide 100 percent of daytime electricity, plus excess, along the border with Jordan.
With solar technology more advanced and cheaper than ever, solar power can take off quickly in Texas, as it has in Israel.
The Arava Desert, where many of Israel’s solar fields are located, averages about 360 days of sunshine per year. Austin, where I live, averages about 300 days per year, and it’s not even as sunny as West Texas. But in January 2016, solar provided just 0.4 percent of power across the vast majority of the state. There is huge opportunity for solar growth in Texas. Read More
On a warm December day, I stood in a jojoba field in the Negev Desert in southern Israel and watched water slowly seep up from the ground around the trees. First a tiny spot, then spreading, watering the plants from deep below. This highly efficient system is known as drip irrigation, and I was there to meet with the world’s leading drip irrigation company, Israel-based Netafim.
Naty Barak, the Netafim director who I met on the visit, notes that if the world’s farmers increased their use of drip irrigation to 15 percent (up from just under 5 percent now), the amount of water available for use worldwide could double.
Drip irrigation saves more than water. Whereas traditional irrigation typically uses quite a bit of energy, drip reduces the pressure (and power) needed to get the water to the crops while reducing the need for energy-hungry fertilizers. Plus, due to the inextricable link between water and power, saving water results in further saved energy.
Texas has already enhanced its water efficiency, but it could go further and take a page out of Israel’s book. By investing in thoughtful drip irrigation now, Texas could lead the nation on expanding this innovative technology and significantly reduce the energy footprint of its irrigation sector, while protecting water supplies for our growing cities and creating more sustainable farming practices.

There’s an old expression that whisky is for drinking and water is for fighting over. The Legislative Session is upon us again in Texas, and count on water being an issue, as it always is in this drought and flood-prone state.
To start, this Session will see the approval of the 2017 State Water Plan (SWP), which is done in five-year cycles. In the five years since the last plan, Texas has gone from the throes of a devastating drought to historic flooding, which resulted in some reservoirs being full for the first time in 15 years.
Moreover, as more people move to Texas and climate change advances, there will be greater strain on the state’s water supplies. According to the SWP, Texas is already in a tighter situation than it was just five years ago: Surface water and groundwater availability will be 5 percent lower in 2060 compared to predictions in the 2012 plan, and existing water supplies are expected to drop by 11 percent between 2020 and 2070. Where are we supposed to get the water we need? Read More
A solar array at the Arava Institute.
Deep in the Israeli desert is an academic institute that is building peace in the region by putting nature at its center. The Arava Institute, in partnership with Ben Gurion University, brings students from Israel, Palestine, Jordan, and around the world to find common ground around environmental problems and build trust – and peace – from there.
On a recent trip to Israel, including to the Arava Institute, I was told many times by many people, “Everything is political here.” Water and energy are no exception. In a region where water can be scarce and oil has long reigned as king, the politics of environmental issues are even more extreme than what people in many parts of the world can wrap their heads around.
Of course, environmental issues in Texas – and across the country – can be highly divisive. But polls consistently show Americans want to protect and defend the health of our children and the well-being of our communities. And clean energy can play a critical role: Our nation’s power sector accounts for nearly 40% of U.S carbon emissions – causing health problems such as asthma attacks, heart attacks, and a staggering number of premature deaths every year.
Today, Texas opens its 85th Legislative Session. Wouldn’t it be refreshing if, instead of fighting over taking action on climate change, leaders sat down with a common starting point: to ensure clean, available water and clean air through renewable energy, while maintaining a robust economy? Perhaps we can learn from the Arava Institute and start with our commonalities, like the desire for clean air and clean water, to build cooperation and achieve clean energy progress. Read More
At my household, a new year means a new energy and water-use baseline. By that I mean, every month, I look at how much electricity and water I used in comparison to the same month the previous year – so I can try to be as efficient as possible. But I work in the energy field, and I know that’s not a typical New Year’s tradition. Most people don’t examine the trends of their energy-use or spend much time thinking about how to reduce it.
So, what motivates the “average” person to take action and be more energy-efficient? It depends.
A recent study by the Pacific Institute for Climate Solutions and the American Council for an Energy Efficient Economy (ACEEE) looked at the psychology behind individuals’ energy efficiency behavior, and how that information could be used to design more effective programs.
The study came away with some fascinating findings that show electric utilities need to be strategic in the way they create, as well as communicate about, their efficiency programs. Moreover, it led me to believe showing how energy efficiency relates to water – the quality and availability of which many people care about – could help encourage people to be more mindful about their energy use.

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
