Powering Texas: Big, Clean, Market-Driven Changes are Already Underfoot

By: Peter Sopher, policy analyst, clean energy, and Sarah Ryan, clean energy consultant

wind-364996_640 pixabayOver 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 »

Reducing Drilling Pollution—Wyoming Did It, No Big Deal. Will Texas?

ozonegraphThe technological advances that led to the “shale revolution” have undoubtedly had a large economic impact on the Texas economy – something state leaders and the oil and gas industry are never shy about pointing out. But the impact drilling has on air quality and public health, that’s something energy-friendly Texas has not been so quick to recognize.

When not managed responsibly, drilling operations can contribute to the formation of ozone, also commonly known as smog. At certain concentrations, this pollution can trigger asthma attacks and cause other severe respiratory illnesses.

San Antonio is one place that’s seeing the clear connection between drilling and lower air quality, thanks to increased drilling just south of the city from the Eagle Ford Shale region. Before 2008, ozone levels in San Antonio had been steadily dropping, but when the shale revolution hit and drilling increased, regional ozone readings started going up.  In fact, based on air quality monitor readings from the last three years, San Antonio’s air quality is the 2nd worst in the state.  This correlation between drilling and ozone levels has been documented by The University of Texas and the Alamo Area Council of Governments, both of which concluded oil and gas activity in the Eagle Ford Shale is materially impacting ozone levels in San Antonio.

Texas Leaders Defy All Logic, Side with Sen. McConnell on “Just Say No” to EPA Campaign

pinwheel-pixabayGovernor Greg Abbott and Texas Senators John Cornyn and Ted Cruz recently met in a meeting with Kentucky Senator Mitch McConnell to discuss how they could sabotage the Environmental Protection Agency’s (EPA) proposed (CPP). The CPP would place the nation’s first-ever limits on carbon pollution from existing power plants – the rules for which are expected to be finalized this summer.

The reason for the meeting is simple: Sen. McConnell is currently touting a “just say no” approach to EPA’s regulations, advocating states refuse to create a compliance plan, which is clearly to protect his coal-producing state. He also supports legislation to let states opt-out of the pollution reduction program. After the closed-door meeting, Governor Abbott announced he is siding with the Senator from Kentucky on the CPP.

What the press release didn’t say: By aligning himself with Sen. McConnell, Governor Abbott is hurting Texas. Read More »

Want to See EDF at SXSW Eco 2015? Cast Your Vote!

Vote-croppedEvery 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.

What Tesla’s Powerwall Home Energy Storage Battery Means for Texas

There is enough solar energy potential in Texas to power the world twice over. Yet currently we rank 10th in the nation (behind New Jersey) with 330 megawatts (MW), which is enough to power about 57,000 homes. Texas is a state of almost nine million households. That’s a lot of rooftops, and when you add the number of commercial and industrial rooftops, parking lots, and garages, we are talking about a significant amount of surface area.

Meanwhile, the cost of solar panels has dropped 80 percent since 2008 and prices for rooftop photovoltaic (PV) systems have declined markedly in recent years, dropping 29 percent from 2010 to 2013. Moreover, jobs in the solar industry are booming –SolarCity is hiring significantly more people than leading tech companies like Twitter.

So, what will it take to energize rooftop solar growth in Texas? Well, a recent announcement from one of Texas’ “frenemies” may be part of the solution. Read More »

A Promise to Our Children to Save Water in Texas

Earlier this week, I testified at a hearing of the Texas House Committee on Environmental Regulation, specifically on how Texas will respond to U.S. Environmental Protection Agency’s (EPA’s) proposed Clean Power Plan (CPP), the nation’s first-ever limit on carbon pollution from existing power plants. But before I went to the Capitol, my three-year-old daughter asked me where I was going. I told her I was going to work, and she asked me, “Mommy, what are you going to save?” I replied that I was going to save water, and she said, “Good job, Mommy.”

That’s exactly what the CPP could do for Texas: save millions of gallons of water each year by encouraging the state to switch from polluting power sources (like coal plants) to non-polluting sources (such as wind and solar farms) and increase no-water solutions like energy efficiency.

Virtuous cycle

It’s no secret that Texas is currently in the midst of a multi-year drought – yet the vast majority of our electricity comes from sources that contribute to this prolonged drought, namely coal, nuclear, and natural gas. All of these energy sources require copious amounts of water to produce electricity. Read More »
