New Technologies Deliver Data That Can Make Gas Pipelines Safer

By Virginia Palacios and Holly Pearen

The tragic 2010 San Bruno pipeline explosion served as proof of how a small pipeline leak combined with human error can cause a devastating disaster.  This has led the Pipeline and Hazardous Materials Safety Administration (PHMSA) to propose new regulations for gas pipelines across the country in order to prevent another major pipeline catastrophe.

At the same time, utilities are beginning to adopt advanced technologies and methods that provide better data to experts —  helping to prevent accidents that threaten public health and safety.  If PHMSA requires operators to use these emerging leak detection technologies and quantification and analytical methods, we could see improved utility safety programs and a decline in incidents related to human error.

When the oil and gas industry spills or leaks harmful fluids – whether toxic oil or chemical-laden wastewater – the damage to local ecosystems can last for decades.

Understanding the most common causes of accidental releases could help stakeholders take corrective measures to avoid them. Unfortunately, many regulators don’t collect and make transparent critical information about how many accidents are happening, and what causes them. Read More »

In Win for Environment, Court Recognizes Social Cost of Carbon

Co-authored with Martha Roberts

If someone was tallying up all the benefits of energy efficiency programs, you’d want them to include reducing climate pollution, right? That’s just common sense.

Thankfully, that’s what our government does when it designs energy efficiency programs—as well as other policies that impact greenhouse gas emissions. And just this month, this approach got an important seal of approval: For the first time, a federal court upheld using the social cost of carbon to inform vital protections against the harmful impacts of climate change.

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.

Smart Policies to Stop Disastrous Natural Gas Leaks

Infrared footage reveals massive methane emissions from a gas storage facility in California’s Aliso Canyon

Last fall, a massive leak from a natural gas storage facility in California’s Aliso Canyon released nearly 100,000 tons of methane pollution into the atmosphere — the largest uncombusted release of this potent greenhouse gas in U.S. history, and seen by many as the industry’s worst environmental disaster since the BP oil spill.

Facilities like Aliso Canyon inject gas pumped in from elsewhere and withdraw it when needed for electric production or heating. Aliso Canyon is the largest field of its kind west of the Mississippi River. There are around 400 such facilities across the U.S., about 14 in California. Until recently, regulatory oversight of these facilities has been uneven at best.

The exact cause of the Aliso Canyon incident is still being investigated, but all signs point to a problem in the aging, corroded casing of one of over a hundred individual wells at the sprawling site. Neither the utility’s maintenance programs nor the state’s lax enforcement of 1980s-era policies were sufficient to prevent this disaster. But now that’s about to change. Read More »

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 »
