Texas Clean Air Matters

It’s not too late to improve Texas plan for VW money. Here’s how.

Texas recently put forth a spending plan for its $209 million share of the settlement from VW’s emissions-cheating scheme, with the goals of reducing smog-forming emissions and protecting people’s health through the repower or replacement of the biggest polluters on the road.

Yet the plan’s author, Texas Commission on Environmental Quality, or TCEQ, ignored some of the oldest, dirtiest engines and equipment. That is a glaring omission because we are learning that these pollution sources—marine tugboats and switcher locomotives that operate at railyards—stay in service for much longer than previously thought. TCEQ’s plan also highlighted that the agency has failed to leverage federal funding for emissions reduction projects for several years.

The good news is that TCEQ can remedy both of these missed opportunities. Read More »

How farms can tend to the energy-water nexus, reduce costs and help their communities

By Kate Zerrenner, Senior Manager of Energy-Water Initiatives, Environmental Defense Fund, and Dylan Dupre, President and CEO, CalCom Energy

Across the country, farmers face unrelenting pressure to conserve both water and energy. From California to Texas, recent droughts and declining groundwater levels require more pumping to provide irrigation water for crops. Pumping water takes energy, as do many other precision agriculture tasks involved in running a successful farm today. This symbiotic relationship between water and energy use – often called the energy-water nexus – is taking its toll on America’s agricultural industry.

For most operations, the result is higher costs, tighter margins and, unfortunately for everyone, a less sustainable food supply.

Demand for food is expected to surge by more than 50 percent as the global population grows to 9 billion people by 2050. In light of this, how can farms adequately manage water and energy to ensure their survival and the security of our food supply?

The answer is not simple, but it is clear: integrated resource management. Farms must consider their use of water and energy together to ensure the optimal use of both. Doing so isn’t just good for the sustainability of our food systems, it’s good for the bottom line. Read More »

Taking shortcuts won’t protect our families from air pollution

We know that air pollution is bad for our families. Science makes that abundantly clear. Studies, for example, show that mercury can damage the nervous system of children and fetuses, while ground-level ozone, or smog, can trigger asthma attacks.

Even pollution levels below those generally considered safe increase the risk for premature death, according to a study of more than 60 million Medicare recipients published in The New England Journal of Medicine in 2017.

Remarkably, when faced with evidence that pollution kills, the Trump administration has attacked science rather than do the necessary work to protect public health and save lives. This excising of science deeply concerns me, as a mother and scientist. Read More »

Houston neighborhood maps decades-old pollution problem, paving way for communities nationwide

Bridgette Murray, a retired nurse, lives in a predominantly black neighborhood on Houston’s east side, where small houses grace tree-shaded streets, all built around two schools and a city park.

Its name is Pleasantville, a postwar version of the American dream. But the reality is something different.

Warehouses, metal recyclers, salvage yards, Anheuser-Busch’s Houston brewery and an interstate push hard against the neighborhood, proof and product of the city’s light-on-regulations approach to land use. Trains and trucks rumble through the area day and night. It can be difficult to breathe.

“Playing victim has never been one of my personality traits,” said Murray, whose family moved to Pleasantville in 1957, years before industry’s arrival. “I am here to work with the residents for solutions.”

As founder of the nonprofit Achieving Community Tasks Successfully, or ACTS, Murray is working with Environmental Defense Fund to fully understand Pleasantville’s air pollution and its associated harmful health effects. She wants to map a fair, just and sustainable path forward for her community. Read More »

A little flexibility can go a long way to maximize renewables

By Jamie Fine, Director, Energy Research & Sr. Economist, Clean Energy

Greentech Media’s Power & Renewables Summit takes place November 13-14, 2018 in Austin, Texas. The conference will gather industry views on how renewable integration, decarbonization and sector electrification are impacting electricity systems.

In the last month, a new report from the U.N. Intergovernmental Panel on Climate Change heightened the urgency of climate threats and the need for decisive actions to avoid them. The report “describes a world of worsening food shortages and wildfires and a mass die-off of coral reefs as soon as 2040.”

As I and other renewable energy insiders plan our talking points for Greentech Media’s “Power & Renewables Summit” in Austin next month, this report should serve as inspiration. The need for a clean, resilient energy economy just got a lot more salient. Read More »

3 reasons Texas’ electric grid survived a summer that pushed its limits

As the hot summer approached, state leaders expressed concern about potential blackouts and brownouts. Yet, thoughtful planning, a functional electricity market, and clean energy helped ensure the lights stayed on.

Power outage concerns­­

Hotter temperatures and continued population and commercial growth drove record electricity demand this past summer. Additionally, in early 2018, Luminant (now Vistra) shut down three large coal plants – all inefficient and highly-polluting – with a combined capacity of 4,200 megawatts (MW).

The shutdown of these power plants and other changes in the electricity market initially led the state’s electric grid operator, the Electric Reliability Council of Texas (ERCOT), to forecast a reserve margin of 9.3 percent for summer 2018. The reserve margin is a measure of whether the Texas grid has extra energy capacity to satisfy periods of strong customer demand, and ERCOT traditionally had targeted a 13.75 percent margin. Potential outages remained a concern even after ERCOT updated its final projections and the reserve margin rose to 11 percent.

As it turned out, even when ERCOT set a new system-wide demand record (73,308 MW) in July, no electricity shortages occurred. ERCOT didn’t initiate any Energy Emergency Alerts, and it didn’t issue any appeals for customers to conserve electricity. Read More »
