A Texas farmer's battle to keep the Keystone XL oil pipeline off her property is only the most visible of what some legal experts describe as a rising tide of property-rights cases across Texas.

Starting last year, federal regulators began urging pipeline operators to replace aging systems. Nowhere may that be more critical than in Texas, which is experiencing a major change in how crude oil is flowing up and down the state.

Texas lags in solar-power development, and lawmakers have been reluctant to promote it with incentives. Nonetheless, solar power can play a role in aiding Texas’ strained electric grid, industry officials and regulators said at a meeting in San Antonio.

UPDATED: Al Armendariz, a former EPA regional administrator, said a court's ruling overturning the EPA's cross-state pollution rule "only delays the inevitable." Texas Attorney General Greg Abbott called the ruling a "victory for federalism."

Oil and gas production has soared in Texas since the introduction of the mining technique called hydraulic fracturing, or "fracking." But the boom in production has also raised concerns about air pollution.

The former EPA regional administrator on his decision to resign, why he joined the Sierra Club and why he views climate change as the biggest environmental problem facing Texas.

The state-regulated maximum price for wholesale electricity takes a big jump on Wednesday, but whether the cost of higher prices will be passed on to Texas consumers remains unclear.

A judge this week reversed the air permit for a proposed coal plant in Corpus Christi called Las Brisas, handing environmental groups a victory and dealing a major blow to one of the few such plants still being planned in Texas. 

A surge in oil and gas production has been a boon for the state's economy, but it has come at the expense of the safety of oilfield workers, who not only face physical injury but also long-term health issues like fibrotic lung disease.

A University of Texas at Austin professor who led a report that denied a link between fracking and groundwater contamination has come under scrutiny for not disclosing financial ties to the oil and gas industry.

The four Republican Railroad Commission candidates sound remarkably similar on the big-ticket topics. But that doesn't mean they will vote the same way on everything once they get into office.

Population growth has strained energy resources in Texas, leading state officials to raise prices in an attempt to encourage new power plant construction. But some utility companies say the increases may not be nearly high enough to meet Texas' growing needs.

Midland lies at the heart of the Permian Basin, a region that produces 14 percent of the nation's oil — and with oil prices high, the place is booming. But the rapid growth has also strained this once tight-knit community as never before.

Midland has always thought of itself as a small town, but an oil boom is rapidly reshaping the area. Housing as expensive (and hard to find) as New York City's has become the norm, and the strain is evident on schools and roads.

The Public Utility Commission approved a 50 percent increase for the cap on wholesale electricity prices on the Texas electrical grid. That will mean higher prices for ordinary Texans, consumer advocates fear.

Much of the discussion at a Wednesday House committee hearing centered around efforts by drilling companies to recycle water or reduce their water consumption. Environmentalists questioned whether they are doing enough.

Texas’ efforts to stave off future blackouts could cost ordinary households hundreds of dollars per year, a filing by a Texas industrial group suggests. Texas regulators are due to vote on the proposal next week.

As summer begins, the spotlight will be on the dunes sagebrush lizard (will it get an endangered listing or not?), former EPA regional head Al Armendariz (who's testifying in Washington) — and, of course, the perpetual question of whether the electric grid has enough juice.
