Fayetteville Shale methane emissions dominated by manual unloadings; National methane emissions are still too high, and avoidable

By David Lyon / Published: November 1, 2018

A new study in the Proceedings of the National Academy of Sciences (PNAS) offers new granularity and insight into a study appearing earlier this year in Science, which found that higher-than-reported methane emissions across the U.S. oil and gas industry methane emissions are largely the result of abnormal operating conditions at a variety of oil and gas facilities across the supply chain.

The new paper, led by researchers from Colorado State University, Colorado School of Mines, the National Oceanic and Atmospheric Administration and others, zeros in on the phenomenon of super emitters, with a specific focus on Arkansas’ Fayetteville Shale.

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

By Kim Rainwater / Published: October 31, 2018

As the hot summer approached, Texas 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 few electricity-making resources would be available beyond the amount customers would likely demand.

A little flexibility can go a long way to maximize renewables

By Jamie Fine / Published: October 30, 2018

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 »

Amendment 74’s multi-billion dollar threat to Colorado taxpayers and our environment

By Matt Garrington / Published: October 26, 2018

With ballots arriving in mailboxes across Colorado, it is time to address Amendment 74, a seemingly innocuous amendment to the Colorado Constitution that would create a nightmare of litigation and severely limit the ability of state and local governments to protect our clean air and water, develop renewable energy, and conserve our treasured landscapes.

As former Colorado Supreme Court Justice Rebecca Love Kourlis pointed out, Colorado’s constitution already protects private property rights. Amendment 74 would create new entitlements that ultimately benefit polluters. It’s no wonder that 99.7 percent of the money backing Amendment 74 comes from an oil and gas group.

The measure would amend Colorado Constitution as follows: Read More »

Sacramento leads by example on cleaner energy with help from electrification

By Lauren Navarro / Published: October 25, 2018

Good news for California’s clean energy fans. Last week the Board of Directors of the Sacramento Municipal Utility District (SMUD) approved an aggressive new plan that will help push California’s capitol city and its surrounding area closer to meeting, and beating, the state’s deep carbon reduction goals. Once implemented, SMUD will help create a cleaner energy and transportation system for the region.

The importance of SMUDs proposed investment shouldn’t be understated, nor should its impact. Between now and 2040, the utility plans to invest nearly $7 billion toward projects that generate renewable energy and help switch consumers’ energy use away from fossil fuels like natural gas and gasoline. This powerful commitment goes above and beyond the greenhouse gas reforms required by the state, and will enable the region to be net zero for climate pollution in a little more than 20 years.

This year’s Greenbuild works to make sustainable buildings accessible to everyone

By Ellen Bell / Published: October 25, 2018

This is my fifth year attending Greenbuild and I am excited that my hometown of Chicago will again host the green building conference. I have come to appreciate the educational value and community that Greenbuild provides more and more each year, and I’m delighted Chicago will get to add to the tradition once more.

Greenbuild’s theme this year, Humans by Nature: The Intersection of Humanity & the Built Environment, covers a wide array of topics that define how we relate to the world we live in. One of these topics is enhancing building efficiency and performance, an ongoing mission that is at the very core of the U.S. Green Building Council (USGBC) and Greenbuild.

Moreover, the mission statement highlights the importance of making sustainable buildings and environments accessible to everyone. As one of the founding cities of the BIT Building energy efficiency program, Chicago reflects these ideals, and the BIT Building program is a clear example of accessibility in action.
