The U.S. power grid could become less reliable if too much electricity comes from renewable energy and natural gas, according to a study from the Department of Energy.

But not everyone is buying it. Environmentalists suspect the Trump administration is just trying to prop up an ailing coal industry.

Energy Secretary Rick Perry called for the study in the spring. The report doesn't say there is a grid reliability problem now — only that one could develop if more coal and nuclear power plants shut down.

Billionaire Warren Buffett has been outbid in his effort to buy Texas’ largest transmission utility.

From Texas Standard:

The nation's electrical grid is an interconnected system that powers homes and businesses across the country. But a recent report by the National Academy of Sciences, Engineering and Medicine indicates the grid is vulnerable and more needs to be done to protect the system from the growing threat of blackouts.

From Texas Standard:

President Donald Trump addressed thousands of people in Warsaw, Poland, Thursday, focusing, in part, on the nation's dependence on Russian energy. He said Poles will not be "held hostage" anymore by the Russian energy market, and pitched U.S. energy as an alternative.

Solar power is one of the fastest growing energy sources in the world. Whether from massive utility-scale solar farms or residential rooftop panels, you can expect to see more solar in the future.

But scientists have identified something that can really hurt the performance of those panels: air pollution.

After an explosion at a fertilizer plant killed 15 people in West, Texas, in 2013, the EPA created new safety protections for the storage of dangerous chemicals. Now, at the urging of the industry, EPA Administrator Scott Pruitt is delaying those rules until 2019.

THOMPSONS — In his first public appearance in Texas since being sworn in as U.S. energy secretary, former Gov. Rick Perry on Thursday heaped praise on a new, first-of-its-kind energy project that captures climate-altering emissions from the state’s largest coal plant and uses them to boost production in a flagging oilfield.

Texas is trying to take the federal government to task for failing to find a permanent disposal site for thousands of metric tons of radioactive waste piling up at nuclear reactor sites across the country.

Have oil and gas companies injected toxic materials into Texas groundwater sources?

In the U.S., we guzzle down data – on our phones and computers – and generally don’t think much about where all that content is stored. It’s stored in places called data centers, and they’re a fundamental part of the infrastructure of the 21st century. The problem: Many of them are stuck in the past. A few companies building data centers in Texas though are trying to boost energy efficiency.

Transforming Dallas Into Something Called A 'Smart City'

Efforts are underway to transform Dallas into a Smart City. That designation involves building an advanced network that can monitor everything from a city's energy consumption to when a garbage can needs to be changed.

Summer school’s now in session for science teachers. It’s being run by the Perot Museum of Nature and Science and Kosmos Energy. The classes target teachers who want to get their students excited about science.

Texas Wind Capacity Is Number One In The Country

From the top of El Centro College, there’s no escaping a skyline that is – in part – a tribute to the fossil fuel industry. Not exactly the place you’d expect to find a wind farm.

Commercial wind turbines stand more than a hundred feet tall, with blades nearly as long. The wind turbines developed by engineers at the University of Texas at Arlington are a bit smaller… just half than the size of an ant.

North Texas Struggles To Improve Air Quality

When the Dallas County Medical Society asked Texas environmental regulators in October to increase pollution controls on coal-fired power plants, they knew it would be a tough sell.

But the association of more than 6,500 physicians said it was fed up with seeing patients suffering from the region’s air quality problems, which are among the worst in the nation.

In Letter, Perry Faults Obama's Energy Policies

Gov. Rick Perry has reminded President Obama – again – that he is no fan of his energy policies.

In a letter sent to the president Friday, Perry accused Obama of “waging a war on coal; kicking the can down the road on the Keystone XL pipeline and creating obstacles to onshore and offshore oil and gas production.”

A Staples distribution center in Coppell has saved more than $65,000 on its energy bill annually, thanks to green measures, employees, and a little help from the U.S. Department of Energy.

The city of Denton is seeking a restraining order against a driller, alleging the company is working on two natural gas wells without the city’s permission. 

The Texas Tribune reports that a complaint was filed Friday in the Denton County District Court. Denton says the Dallas-based EagleRidge Energy ignored the city's demands to stop working on wells about 5 miles southwest of downtown. The city never permitted the development, the complaint says, and the wells lie too close to housing development, violating city rules.

The largest federally-owned wind farm is about to be built at the Pantex Plant in Amarillo, Texas, the Department of Energy (DOE) announced today. The five-turbine project will power more than 60 percent of the plant once it is complete.

Fracking hasn't only boosted natural gas production in Texas, its also raised oil production in Texas to unprecedented levels. In March, Texas oil production reached its highest level since 1984.

Scientists say there’s enough wasted energy in Texas to power our lights for centuries. KERA’s Bill Zeeble reports on SMU researchers and a business who are turning waste heat from oil and gas wells into electricity.
