Saving Energy and Doubling Worldwide Water Supplies – One Drip at a Time

Netafim HQOn 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.

Lowering Desalination’s Energy Footprint: Lessons from Israel

IMG_8244

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 »

Why Clean Energy is Center Stage on International Day of Peace

poster-largeEach year since 1981, the United Nations (UN) recognizes an International Day of Peace on September 21. The day is intended to strengthen peace both within and among nations.

As an environmental advocate, I can’t help but think about the effects of climate change on the current state of global peace. And while there are a few climate deniers out there, those who have looked at the science are saying climate change poses a serious threat to global security and peace.

Fortunately, the UN agrees – which is why they chose to focus this year’s International Peace Day on Sustainable Development Goals. Unanimously adopted by all 193 UN member states, the Sustainable Development Goals are broken down into 17 focus areas and are part of a broader agenda to fight inequality, injustice, and climate change by 2030.

Goal 7 – “ensure access to affordable, reliable, sustainable, and modern energy for all” – is a hugely important part of fostering global peace. The world needs affordable, reliable electricity to heat, cool, and power our homes, and to encourage economic growth. But we also need this electricity to be clean, modern, and efficient, so it doesn’t pollute our communities and exacerbate climate change.

Here are four ways the U.S. is doing our part to achieve an affordable, reliable, sustainable, and modern energy system for all:

2 Ways El Paso Just Upped Texas’ Solar Game

SolarPanelArrayThe city of El Paso has many nicknames, but “The Sun City” is probably the most well-known. After two important energy updates this summer, West Texas’ largest city has even more reason to call itself that.

First, El Paso Electric, the public utility that serves nearly half a million customers, reached a major milestone: It is now officially 100 percent coal-free and has pledged to increase its solar investment. Second, the utility agreed to eliminate its proposal that would have resulted in different electricity prices for customers with solar panels at their homes. Such a pricing structure would have placed an unnecessary burden on El Pasoans with solar.

Sunny El Paso has incredible potential for solar power, and both of these developments are positive signs for the city’s clean energy future. Let’s take a closer look at each.

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.

Why 10,000 Spills From Oil and Gas Development Can’t Be Ignored

THe "Texon Scar" A massive release of produced water from an oil well in West Texas caused a vegetative dead zone that can be seen from space

The "Texon Scar"
A massive release of produced water from an oil well in West Texas caused a vegetative dead zone that can be seen from space.

Oil and gas development produces massive amounts of air and water pollution that can have severe impacts on our communities and ecosystems.  And data in a recent investigative article could help us understand more about where and how much oil, wastewater, and other fluids are spilled across the country.

According to an EnergyWire  article by Pamela King and Mike Soraghan, in 2015 industry reported more than 10,000 cases of spills across the country.  That amounts to 42 million gallons of harmful fluids – 12 million gallons more than previously reported.
