Texas State Climatologist on Politics, Weather, and Setting the Facts Straight on Climate Change

John Nielsen-Gammon, Texas State Climatologist, is a tried and true Texan. As a professor in the Atmospheric Sciences Department at Texas A&M University, he observes Texas weather patterns, monitors the state’s multi-year drought and air pollution climatology, and makes improvements to the climate data record. I recently had the chance to pick his brain over weather, climate change, and the state of affairs in Texas.

For those of you unfamiliar with the Lone Star State, Texas is a state of extremes. We have a history of extreme weather patterns and extremes between our climate zones. We also have extreme views about Texas’ climate and whether it is changing. Unfortunately, polarized views can distort perceptions on important issues. Regardless of the scientific data that confirms our changing climate, the subject has become so politicized that it’s nearly impossible to discuss. However, there shouldn’t be a debate over whether to use all of the available data to ensure that Texas is appropriately planning for its viable economic, natural, and demographic future.

Here is what Dr. Nielsen-Gammon had to share: Read More »

How will Texas Fare in the New Climate Future?

Early this week, the White House released the third National Climate Assessment (NCA). What’s the main take away? That Americans are already feeling the effects of climate change.

The NCA, authored by 300 experts and guided by a 60-member Federal Advisory Committee, analyzes the best available data in the U.S. on the observed and future impacts of climate change, and organizes its findings for specific sectors and regions. Texas falls under the Great Plains region and the state’s bustling economy includes many industries that will be affected by a changing climate, such as agriculture and energy.  Our water, ecosystems, transportation, and more will also be affected. It is clear from this report that heat and drought will intensify in Texas, putting energy, agriculture, and human health at increased risk. State leaders need to enact policies now to protect us and our livelihoods.  Read More »

Demand Response: People, not New Power Plants, are Driving the Clean Energy Future

By: Cheryl Roberto, Associate Vice President, Clean Energy

Clean energy resources, like wind, solar, and energy efficiency, have certain key advantages over traditional, fossil fuel-based resources: they don’t require expensive, polluting fuels or large capital investment, consume little to no water, generate negligible carbon emissions, and are easily scalable. To take full advantage of low-carbon, renewable energy sources, we need a power grid with enough flexibility to harness clean energy when it is available and abundant. That’s where demand response, a people-driven solution, comes in.

On a hot summer day, for example, electricity use rapidly increases as people turn on air conditioners to avoid the heat of the late afternoon. A decade ago, the grid operator’s only option is to turn on another fossil fuel power plant to meet the increased need for electricity. But, at any given time, there are thousands of light switches left on, idle water heaters, cycling swimming pool pumps, and forgotten thermostats that people could temporarily turn off or down, if only they were offered the right incentive. If asked, people can adjust their power usage in exchange for a financial reward. We call this “demand response,” and it is increasingly helping to balance the flow of electricity with our energy needs at a given moment.

Demand response diverts money that would generally go to a fossil fuel power plant to homeowners and businesses instead. In this scenario, a utility or demand response provider sends a message for participants to reduce electricity use at key times in exchange for a credit or rebate on their utility bill, in addition to the cost savings they will earn through conservation. Of course, participants always have the option to opt-out with the tap of a button on their smart phone or thermostat. Read More »

Showtime Brings Realities of Texas Drought Home to Millions

It may seem like only yesterday that Texans were asked to conserve water after another scorching summer, but in reality it was four, dry years ago. The drought, which began in 2010 after La Niña altered sea level temperatures in the Pacific, continues to persist in the Lone Star State and promises to surpass the state’s record-setting multi-year drought from the 1950s. Ranchers have been forced to sell off cattle, town water supplies continue to go dry, and power plants struggle to provide a reliable supply of electricity due to water scarcity and long stretches of hot weather. Given these bleak conditions, it should not come as a surprise that 70 percent of Texans believe global warming is happening—and 52 percent said they have personally experienced the effects of global warming.

An all-star team of producers, including James Cameron, Jerry Weintraub and Arnold Schwarzenegger, intends to bring the Texas drought home to millions of televisions across the nation in the Years of Living Dangerously series premiering Sunday. Through this series, a host of celebrities, activists and journalists share the stories of those impacted most by our changing climate and what’s being done to save our planet. What is clear right now, in Texas and beyond, is that as climate change intensifies, we must adapt to more extreme weather conditions and make resilient changes that mitigate further stress.

Freezing, Scorching, or Not, Texas Needs More Demand Response

MaritaHeadshotAs we thaw out this week from our most recent arctic blast, Texas’ inexperience with ice and snow has been met with Internet memes and jokes. But dealing with extreme temperatures causes serious strain on our current energy system and exacerbates our “energy crunch,” signifying that the available supply of electricity barely meets the demand for that power.

However, as is typical of Texas, last week our weather was quite pleasant – in the 70s – and strains on the system due to weather events weren’t too much of a concern. Yet the Electric Reliability Council of Texas (ERCOT), the state agency charged with managing the flow of electricity for most of Texas, alerted an emergency situation despite mild temperatures. To avert disaster, ERCOT initiated demand response, “ask[ing] customers to raise thermostat settings to 78 degrees, typically a summer response intended to reduce demand from air conditioners.” A single malfunctioning power plant caused the problem. ERCOT declined to identify the plant involved.

Demand Response Helps Texas Avoid Rolling Blackouts in the Face of Polar Vortex

MaritaHeadshotAs we begin a new year, the outlook for 2014 looks bright.  But as the Polar Vortex has descended upon the U.S. over the last few days, we have been reminded of the past, specifically the winter of 2011 when Texas’ electricity grid stuttered under the extreme cold.

Monday, as a record-breaking cold snap whisked over the U.S., the Electric Reliability Council of Texas (ERCOT), the state’s grid operator, warned of possible blackouts, just as they did in 2011.  We were lucky this time, but in February of 2011 we were not, and blackouts occurred throughout the state.

ERCOT’s warning meant that the grid's power reserves “dropped below a comfortable threshold,” and the "system was just one step away from rolling blackouts” as the need for energy outpaced supply.  As these blackout threats loomed, two power plants succumbed to the cold and went down.  The loss in capacity amounted to about 3700 megawatts (MW), with 1800 MW lost due to the cold.  According to Dan Woodfin, ERCOT’s Director of System Operations, “if we had lost another unit it would have put us into an Energy Emergency Alert Three” – the stage that prompts rolling blackouts.  This is unnecessary and unacceptable.
