Texas’ Evolving Energy Reality: Clean Energy Uses Less Water

By Kate Zerrenner / Published: June 13, 2016

And a few weeks ago, the Texas Water Development Board (TWDB) asked for comments on the draft 2017 State Water Plan. The TWDB is the state agency responsible for water planning, and every five years it produces a strategy that “addresses the needs of all water user groups in the state – municipal, irrigation, manufacturing, livestock, mining, and steam-electric power.”

In the five years since the last state water plan, Texas has gone from one extreme to the other in terms of water: from the throes of a devastating drought to historic flooding that resulted in some reservoirs being full for the first time in 15 years.

In this climate of feast or famine, we need to better understand our water supplies and conservation efforts, both of which have a strong tie to our energy choices. That’s why Environmental Defense Fund (EDF) weighed in on Texas’ draft water plan. Not only does the state significantly overestimate the amount of water needed to make electricity, but a more comprehensive view of energy in relation to water demand and supply would benefit the 2017 State Water Plan and future plans.

3 Clean Energy Ideas the Left and Right Agree On

By Diane Regas / Published: June 13, 2016

6964013353_e7ec857740_oAmericans across the political spectrum support clean energy. They know it’s good for our economy, our environment and our health. And they know that for too long it’s been held back by partisan politics.

That’s the message from groups that announced the Clean Energy Commitment this week. The broad spectrum of groups – from Mom’s Clean Air Force to Young Conservatives for Energy Reform – rolled out a set of proposals to promote clean energy, give consumers more choices, save taxpayers money, and reduce carbon pollution.

While Washington sees nearly everything through the lens of partisanship, most Americans don’t.

It’s an agenda that can unite us in the cause of giving our kids a healthier future, and producing jobs today. Read More »

Keeping an Important Methane Research Question in Proper Perspective

By EDF Blogs / Published: June 9, 2016

 

By Mark Brownstein and Steve Hamburg

An organization in North Carolina this week asked the U.S. Environmental Protection Agency to examine questions about the accuracy of measurements from a device used in two of the large and growing list of studies published in recent years quantifying the enormous amounts of methane released into the atmosphere by the U.S. oil and gas industry each year.

That long list of studies is a major reason why EPA recently increased its official estimates of industry emissions by 34 percent, and why the agency is pursuing new rules to start fixing the problem.  In fact oil and gas methane emissions have moved from obscurity to center stage with remarkable speed, thanks to rush of compelling data.

The particular papers at issue were written by a team of scientists led by Dr. David Allen of the University of Texas. They are among of a group of studies on oil and gas industry methane emissions organized and coordinated by EDF. Possible complications involving a piece of sampling equipment (among several that were used) have been discussed by researchers in both academic literature and the news media for more than a year. You can read the blog that EDF wrote on it back in 2015 here. Read More »

Industry Study Applies Own Numbers to EDF Study, Strengthens Our Case for Regulation

By Mark Brownstein / Published: June 3, 2016

The natural gas industry group Our Nation’s Energy (ONE) Future Coalition released a paper yesterday applying their own set of assumptions to an earlier analysis commissioned by EDF, which had shown that oil and gas methane emissions can be dramatically reduced for about a penny per thousand cubic feet of gas sold. Both analyses were carried out by ICF International.

We always welcome new points of view, but it’s important to note the new calculations change key variables in ways that boost the cost of reducing methane emissions while significantly understating benefits of these reductions. An even bigger problem comes when others in the industry public relations machine start to mischaracterize the study.

Despite these changes, the results still end up making what we think is a strong case for sensible regulatory standards to make sure that best practices become the standard practice industry-wide in order to reduce the oil and gas industry’s nearly 10 million metric tons of yearly methane emissions.

New York Takes a Major Step toward Rethinking Utility Economics

By Rory Christian / Published: June 2, 2016

NY Lights BridgeThroughout the United States, utilities earn a profit through a tried and true regulatory model that has worked well for over 100 years. This model was built on the assumption that customers would use ever increasing amounts of electricity, and it worked for some time. But, as the need to save power and make electric systems more efficient becomes essential to adapt to climate change, this and other assumptions no longer hold true. Without changing how utilities are compensated, we run the risk of experiencing a true irony: utilities, the cradles from which our modern civilization rose, may become the chains preventing us from advancing toward a clean energy future.

Last week, the New York State Public Service Commission (PSC) – which regulates the state’s utilities – took action to transition to a new model aligned with Reforming the Energy Vision (REV), the state’s initiative to transform the electric grid into a cleaner, more efficient and affordable system. By issuing the “Order Adopting a Ratemaking and Utility Revenue Model Policy Framework,” the PSC is changing how New York’s utilities will be compensated, taking a major step to break the chains holding utilities back, and moving from a system where utilities get paid according to how much electricity they sell to one where utilities are compensated for producing environmental benefits aligned with the public good.

3 Key Energy Policies that Can Help Us Turn the Corner on Climate

By Diane Regas / Published: June 1, 2016

We know we need massive decreases in greenhouse gas emissions by 2050 if 177 countries are to meet the goals of the Paris climate agreement.

But before emissions go on a steep decline, we need to turn the corner. At Environmental Defense Fund, we have analyzed what it would take to turn the corner by 2020, and zeroed in on a few key actions that will halt the rise in global emissions and make them start to go down. For good.

Christiana Figueres, the United Nations official who led the Paris climate talks, rightly talks about technology, finance and policy – technologies to store and distribute energy, financing to scale the technology we have, and policies to reward innovators who deliver results. Read More »
