National Academy of Sciences urges collective research improvements to track U.S. methane emissions

By David Lyon / Published: March 30, 2018

This week the National Academy of Sciences, Engineering and Medicine (NAS), the nation’s most prestigious scientific organization, issued a report calling for a stepped-up nationwide research effort to develop a gridded and verifiable inventory of U.S. methane emissions.

The NAS report, sponsored by the U.S. EPA, Department of Energy (DOE), National Oceanic and Atmospheric Administration (NOAA), and NASA, noted atmospheric methane has risen dramatically in the 20^th century, hitting a spike in 2016 that has tripled since pre-industrial times. Methane is a potent greenhouse gas responsible for about 25% of current global warming.

The report discusses all the major U.S. sources of anthropogenic methane emissions, including petroleum and natural gas systems, agriculture, landfills, and coal mines. Researchers acknowledged the rapid increase in natural gas production in the U.S. during the past decade has triggered the need for a better understanding of the energy industry’s methane footprint. The NAS report classified oil and gas as one of three primary research priorities for the future, along rice farming, and livestock.

Meet the women of the clean energy and sustainability workforce

By EDF Blogs / Published: March 27, 2018

By Ellen Shenette, Manager, EDF Climate Corps

I remember some of the first interactions I had with companies working in the clean energy industry. I was an analyst at the time, which meant the conversations were more often than not, very technical, wonky, and with men. At first, this was overwhelming. But my all-women MBA program prepared me for the male-dominated business world. I turned these initial concerns into motivation, and I built my technical expertise so that I could hold my own in conversations. If my knowledge was questioned, I was ready with an answer.

I’m not alone in this experience. Like many other STEM industries, women are underrepresented in the energy workforce, counting for only roughly 20-35 percent. The good news is that this trend is changing, and clean energy is leading the way. The clean energy sector is the farthest along in closing this gender gap compared to other energy sectors, opening up numerous opportunities for women looking to start their careers in this field, and I’m proud to be helping to make this possible.

EDF Climate Co rps is working to build the next generation of sustainability leaders, and we’re making sure that includes women. Why? Research has found that more gender equity leads to higher performing companies, and female leaders rank the highest in their ability to take initiative and drive results.

Since EDF Climate Corps started in 2008, women have represented 41 percent of our fellows. I decided to reach out to these women from our alumni network, a group of nearly 850 sustainability experts, and learn more about their jobs and gather any advice they have for women looking to join the industry.

Still cheaper than coal – a report on the economics of solar power in Colorado

By EDF Blogs / Published: March 27, 2018

By Rama Zakaria, Graham McCahan

A newly-updated report is shedding light on what President Trump’s solar trade tariffs may mean for one state – and underscoring a tremendous opportunity to move forward toward clean energy, with all the benefits it can bring.

Xcel Energy filed its 30-day bid report update with the Colorado Public Utilities Commission on March 1. The update follows Xcel’s filing at the end of last year, in response to an “all-source solicitation,” as part of its Electric Resource Plan and its proposed Colorado Energy Plan.

Xcel’s plan would shut down two units at the Comanche coal plant in Pueblo, Colorado, and replace the capacity with a mix of lower-carbon resources. Earlier results were unprecedented, with more than 80 percent of the bids coming from renewable energy and storage at incredibly cheap prices.

Xcel then provided bidders an opportunity to refresh their bids following President Trump’s final decision in the Suniva/SolarWorld trade case in January, which imposed tariffs on imported solar equipment.

The refreshed bids in Xcel’s updated report show minimal change relative to last year’s results and confirm that new wind and solar power in Colorado continues to be cheaper than existing coal plants – despite the trade tariffs. Read More »

New England’s energy future lies in the balance

By N. Jonathan Peress / Published: March 23, 2018

As recent and ongoing activity regarding fuel security, renewable energy procurement and natural gas infrastructure make clear, the energy system in New England is at a critical juncture, the responses and solutions to which will shape the region’s economy for the next 30 years or more.

ISO-NE, the regional electricity grid operator, released its fuel security study raising legitimate reliability concerns based largely on the sufficiency of pipeline infrastructure and expanding deployment of renewable energy. Meanwhile, the Federal Energy Regulatory Commission (FERC) initiated a comprehensive review of electric system resiliency, including reliability and fuel security. Read More »

Federal rollbacks + huge new oil and gas project = trouble for Wyoming

By EDF Blogs / Published: March 23, 2018

This blog was co-authored by Jon Goldstein and Sara Brodnax

Last week, the U.S. Department of the Interior’s Bureau of Land Management collected comments from citizens and groups concerned about the impacts of a proposed 5,000-well oil and gas project in eastern Wyoming.

The situation has a troubling irony, because as BLM reviews the project’s environmental risks, it is simultaneously working to roll back its own commonsense standards to stop oil and gas companies from venting, flaring, and leaking away pollution and valuable natural gas.

It’s the same story for the greater sage-grouse, which without strong mitigation measures will likely abandon critical breeding sites in the area set to be impacted by the planned oil and gas project. Here, too, BLM has signaled several attempts to unravel the collaborative, decades-forged plans to protect the imperiled bird.

The combination of weakening policies while expanding development could have disastrous consequences for Wyoming and other western states if methane pollution goes unchecked and the greater sage-grouse continues to decline.

New research shows Canada’s methane emissions problem is even worse, but it’s not hopeless

By Drew Nelson / Published: March 22, 2018

This post was co-authored by Dr. Daniel Zavala-Araiza.

New direct emissions data from oil and gas fields in Alberta should be a warning to regulators in Ottawa and Edmonton as they each prepare their methane regulations. A new study concluded that oil and gas methane emissions are 15 times higher than industry reports for 60 production sites measured in Red Deer. The discrepancy highlights the importance of strong federal and provincial regulations to address a problem science is continually showing to be much worse than industry claims it is. Strong regulations will show the world that Canadian gas can compete with lower-carbon gas supplies.

The research, published today in Elementa, uncovered that methane emissions from the oil and gas industry in Red Deer, Alberta are larger than companies estimate and that methane “super emitters,” a phenomenon we found in the U.S. oil and gas industry, may be just as much of a problem in Canada.
