The earthquakes that have shaken Dallas and Irving, Texas the last several months have people looking into whether oil and gas activity in the area plays a role. Some of those people work at the Environmental Protection Agency. But EPA researchers say they’re not getting the data they’ve requested from Texas state oil and gas regulators to investigate the possible link.
Philip Dellinger is head of the EPA’s Underground Injection Control Section in Dallas. At a conference of the Groundwater Protection Council Tuesday, he showed early results from a study his team conducted on earthquakes around Irving.
The group looked at the use of wastewater disposal wells closest to Irving earthquakes. Dellinger does not necessarily believe the recent quakes are related to disposal wells, where wastewater from oil and gas drilling is pumped underground. But these types of wells have caused other earthquakes, so his team wanted to see what wells were close to the Irving events.
His choice for where to look was simple. There are only two wells near the recent quakes, and one had been plugged up.
James Tour leads research at Rice University to develop smaller, more powerful batteries.
One of the nation’s leading researchers who’s trying to make batteries better is James Tour and his colleagues at Rice University.
“Everybody’s investing billions. If you say millions they scoff at you,” Tour told News 88.7.
Tour says there are three categories of things that need better batteries: portable electronic devices, electric vehicles, and a use we wanted to learn more about: batteries to store huge amounts of electricity to power homes and businesses.
“We are not there yet to be able to store large amounts of electricity. So in other words you have huge banks where you can store electricity at night while people are sleeping.”

The SMAP satellite will monitor drought levels around the globe.
A satellite launched by NASA over the weekend could help people around the world tackle the challenges of drought. Researchers at the University of Texas will play a part in that mission that could also help forecast flooding and allow officials to better manage reservoir water supplies.
The SMAP (Soil Moisture Active Passive) satellite that launched on Saturday will carry two devices to track drought. One to measure heat from the earth’s surface and the other a radar sensor to help pinpoint the location of the land surveyed. Researchers say that by using the two different technologies, they will get a clearer understanding of where the soil is parched and where it is well-saturated around the globe.
That information will be complimented with data gathered by soil moisture monitors, some of them installed around the Texas Hill Country by UT’s Bureau of Economic Geology. These on-the-ground sensors will help validate and improve the satellite’s readings.

The financial markets may be betting that the Keystone XL pipeline is a done deal.
The U.S. House and Senate have now both passed bills to force approval of the controversial pipeline. The southern leg of the project already delivers oil from Cushing, Oklahoma to the Texas Gulf Coast. But approval of the full build-out would link existing pipe to the Canadian border, allowing more crude from the tar sands of Canada to reach Texas refineries via Cushing.
President Obama has vowed to veto the bills, but one expert says the fate of the project may already be written in futures contracts for crude oil.

By now, the initial surprise over low gas prices has worn off. But people looking for the very best deals might have noticed a trend: small, unbranded gas stations are often the first to cut prices. Many of them continue to stay competitive even when larger brand-name stations cut their prices as well.
To understand why stations offer different prices for essentially the same product, it helps to take a trip from the pump back to the pipeline, to see exactly how gas is bought, sold and transported.

This map from the USGS shows the approximate location of a recent quake near Irving, Texas.
Updated 1/6/14 with more comment from Railroad Commission and information on Tuesday January 6th earthquake.
A team of seismologists headed to the North Texas town of Irving Monday. Like some other Texas towns, Irving has experienced scores of small earthquakes lately, 20 since last September, including a magnitude 3.5 quake that struck on January 6th. And the city is hoping to figure out what’s behind the shaking.
The upsurge in quakes started in Texas around the time the oil and gas boom took hold several years ago. Residents in many parts of the state blame the them on wastewater disposal wells, where fluid byproducts of oil and gas drilling are pumped deep into the ground. Scientists have shown how injecting fluid into the ground can cause earthquakes.
After a spate of quakes in the North Texas town of Azle, the Railroad Commission of Texas, the state’s oil and gas regulator, hired a seismologist, Dr. David Craig Pearson, and passed new regulations for disposal wells. The Commission says it is not investigating the Irving quakes.
“The Railroad Commission is not investigating seismic activity around Irving,” Ramona Nye, a spokesperson for the Commission wrote in an email to StateImpact Texas. “Specifically, there are no disposal wells in Dallas County, and there is only one natural gas well in the vicinity, and it is an inactive well.”
Cyclist commuting in the Copenhagen neighborhood of Norrebro.
Rain or shine, in the light of summer or the early afternoon darkness of winter, under heavy sleet, unrelenting winds or drifts of snow, people in Copenhagen just bike. They bike in fur coats, they bike in suits and ties. They bike old, they bike young. They wheel their kids around on a cargo bike with a wooden box carrying the children up front, taking them to and from school; this is Copenhagen’s take on a minivan. People just bike, and after arriving in the city myself, I soon found out why: it’s usually the fastest way to get around. So I rented a bike, too.
Today, 60 percent of people in the city’s core commute by bike. In the greater Copenhagen area, over 40 percent do. “We see the same numbers [of commuting by bike] all year round,” says Copenhagen Environmental and Technical Affairs Mayor Morten Kabell.
“It’s not something that’s in Copenhagen’s genes, or that we’re weirder or stranger than any other people on earth,” Kabell says. “Every city can do this.”
Copenhagen has had enormous success getting people out of their cars and onto bikes, public transit and their own two feet. But this development has less to do with Danes wanting to save the planet, and much more to do with saving their own sanity.
Standing on the shore of the Baltic sea a few miles outside of Copenhagen, Denmark, the view’s about what you’d expect. Rocky shore, grey horizon, a boat here or there. But this shore is special. Look up, and you’ll see — and hear — three giant offshore wind turbines cutting through the air. Each stands 500 feet tall, with three blades (each close to 200 feet long), spinning non-stop.
“The blades look quite thin, but don’t be cheated,” says Rune Birk Nielsen, with DONG Energy, which runs the turbines. “They each weigh about twenty tons. They are massive.” Each turbine has a capacity of 3.6 megawatts, or enough to power 3,000 Danish homes.
Nielsen guides me through the small offshore wind park — well, technically it’s offshore. The turbines aren’t actually too far from land — each is connected to the shore by a short footbridge about ten yards long.
“For us, it’s kind of a demonstration park,” Nielsen says, “where we are able to test all sorts of things.” With turbines close to shore, they’re easier to fiddle with or repair. The company can safely train their workers without sending them far out to sea, where most of the country’s offshore turbines are.
Denmark is booming when it comes to wind energy. To understand how and why, you have to go back a few decades. Continue Reading
Cathy McMullen and Tom Giovanetti debate a proposal to ban fracking at a meeting of the County GOP Womens Club.
Update, Nov. 5: Denton voters passed a local ban on “fracking,” an oil and gas production process. 59 percent of voters said “yes” to the ban, with 41 percent voting against. The Texas Oil and Gas Association (TXOGA) wasted no time in filing a request to overturn the vote, saying it violates state law.
Original story, Oct. 21: For Cathy McMullen, the reasons to ban fracking in Denton are as obvious at the drilling rig that sits on the corner of Masch Branch and Hampton Road on the northwest side of town. It’s big, it’s noisy, and she believes it vents toxic emissions into the community. The site is, however, not very close to any houses.
“I’ll show you where this exact same thing was sitting by someone’s home,” she says.

A recent drop in carbon emissions in the U.S. could only be temporary, a new report warns.
Texas will need to make big cuts in carbon emissions over the next 15 years under a mandate from the Environmental Protection Agency. You can expect to hear complaints about the EPA rule at a two-day meeting of the House Environmental Regulations Committee starting Monday.
The federal agency and state leaders have been at odds for years and many conservatives worry that limiting carbon emission to fight climate change will hurt the economy.
But there are some in Texas who see an upside. Click the player to learn more.
