Over the past century, the electric grid in the United States has experienced only minor changes. There is evidence, however, the power sector is changing. We are moving away from traditional coal generation and toward alternative, cleaner energy sources. And despite our state being primarily known for oil and gas, Texas is no exception.
In fact, Texas’ electricity sector has been trending cleaner over the past decades, driven by deregulation of the electricity market, the development of the massive highway of transmission lines built to carry West Texas wind to cities throughout the state – the Competitive Renewable Energy Zone (CREZ), and technological progress. Basically, once the market was opened up to competition, the more economic options – which also happen to be cleaner – began to gain a foothold. And there’s no stopping this train.
Where we are and where we’re going
To start, the declining use of fossil fuels to power our lives is perhaps the most significant change in Texas. As shown in Figure 1 below, fossil fuels’ (coal and gas’) proportion of the state’s electricity generation mix shrunk from 88 percent in 2002 to 82 percent in 2013. Read More

Here we go again.
A new set of peer-reviewed scientific papers pointing to 50 percent higher than estimated regional methane emissions from oil and gas operations in Texas were published this week. And like clockwork, the oil and gas industry’s public relations machine, Energy In Depth, proclaimed that rising emissions are actually falling, and that the industry’s meager voluntary efforts are responsible.
This is, of course, wrong on both counts. In fact, it’s a willful misrepresentation of the findings.
First, the assertion that emissions are going down is flat wrong. EPA’s latest inventory released in April reports that in 2013 the oil and gas industry released more than 7.3 million metric tons of methane into the atmosphere from their operations—a three percent increase over 2012—making it the largest industrial source of methane pollution. So much for those voluntary efforts. Read More

Methane emissions from vast oil and gas operations in the densely populated Barnett Shale region of Texas are 50 percent higher than estimates based on the Environmental Protection Agency’s (EPA) greenhouse gas inventory, according to a series of 11 new papers published today in Environmental Science & Technology.
The majority of these emissions are from a small but widespread number of sources across the region’s oil and gas supply chain. These emissions come from the sort of leaks and equipment malfunctions that are relatively easy to prevent with proper and frequent monitoring and repair practices.
The sprawling Barnett region, fanning out westward from the cities of Dallas and Fort Worth, contains about 30,000 oil and gas wells, 275 compressor stations, and 40 processing plants. It is one of the country’s largest production areas, responsible for 7 percent of total U.S. natural gas output.

When I landed in Las Vegas last week, the weather was a broiling 108 degrees. Ouch.
I braved the Las Vegas heat for one of the most inspiring convenings of Latino leaders in the country, the Annual Conference of the National Association of Latino Elected Officials (NALEO). We had a chance to hear from established and rising Latino leaders, as well as from Presidential candidates, about the challenges facing Latino communities and the many paths forward for creating a brighter future.
What we did not hear about was a vision for places like Las Vegas, where summer temperatures are bound to get hotter and water will become even more scarce in the face of climate change. In fact, there was no formal conversation about what climate change means for the U.S., and specifically for Latinos.
Here’s the short version of the missing conversation on climate: climate change presents challenges to everyone but it has, and will continue to have, a disproportionate impact on Latinos in the United States. Read More
Every year, SXSW Eco – one of the most high-profile environmental conferences – selects its programming based on votes from the public. This means anyone, regardless of whether you submitted a panel, can cast a vote.
This year, seven experts from Environmental Defense Fund are featured on dynamic panels that cover everything from solar equity and new utility business models to innovative building efficiency programs and the threat of methane pollution. To make sure EDF and energy-related programming is represented at the conference in Austin, TX this October, we are asking our readers to please vote for your favorite EDF panels and presentations.

This Saturday, the Texas Air Quality community will celebrate the life of Bill Gill. Most of us knew Bill either as Air Quality Program Manager at the Capital Area Council of Governments (CAPCOG) or as the Emissions Inventory Section Manager at the Texas Natural Resources Commission (TNRCC). Bill dedicated his life to public service and improving air quality in Texas, and every day of his 42-year career in air quality put the principles of the Environmental Defense Fund into action – guided by science and economics, he found practical and lasting solutions to Texas’s air quality problems.
His career was extraordinary. In 1972, the State of Texas submitted its first State Implementation Plan under the Clean Air Act. Bill may not have known it at the time, but his career would become a major part of the state’s air quality plans over the next four decades. That same year, he started working in enforcement at the Texas Air Control Board (TACB), which was part of the Texas Department of Health at the time. A decade later, he helped establish the state’s Emissions Inventory section, and later served as the Emissions Inventory Section Manager until he retired in 2002 from the TACB’s successor agency, the TNRCC. In his time at TACB and TNRCC, he built one of the premier programs in the world for assessing emissions and ensuring that decisions on air quality had the best information available. Bill’s work won him national recognition: as the TNRCC’s Emissions Inventory Section Manager, he also co-chaired the national point source committee of the Emissions Inventory Improvement Program for the U.S. Environmental Protection Agency (EPA).
