Fostering Effective Energy Transition 2022 5/11/2022

Fostering Effective Energy Transition 2022

Payne Institute Director Morgan Bazilian contributed to this World Economic Forum report on how the global energy transition builds on the trends from the Energy Transition Index to provide perspective on the current challenges and recommendations on how to navigate the transition through a turbulent macroeconomic and geopolitical environment. A series of compounded shocks pose short-term risks to energy affordability, sustainability, and energy security. However, the window to prevent the worst consequences of climate change is closing fast.  May 11, 2022.

Estimating global economic well-being with unlit settlements 5/5/2022

Estimating global economic well-being with unlit settlements

Payne Institute Earth Observation Group writes about how it is well established that nighttime radiance, measured from satellites, correlates with economic prosperity across the globe.  For 49 countries spread across Africa, Asia and the Americas we are able to predict and map the wealth class obtained from ~2,400,000 geo-located households based upon the percent of unlit settlements, with an overall accuracy of 87%.

Power Outage in Afghanistan as Seen by DNB 4/20/2022

Power Outage in Afghanistan as Seen by DNB

Payne Institute Earth Observation Group Research Associate Tilottama Ghosh writes about how the economic and humanitarian crisis in Afghanistan following the withdrawal of the US Armed forces, which was completed on August 31st, 2021, can be viewed from ‘space.’ Areas which were lit before become dimmer or become completely dark because of the loss of electricity.  April 20, 2022.

Project Canary Adds to Independent Stature with 3rd Party Assessment of ESG Data by Big Four Accounting & Payne Institute

The Payne Institute is happy to partner with Project Canary on methane and emissions monitoring and data science to ensure independent verification and assessment of data and operating standards.  The Payne Institute will also perform a third-party assessment of all Project Canary internal controls and data analysis.  March 23, 2022.

Colorado clean energy policy landscape: A case study 3/11/2022

Colorado clean energy policy landscape: A case study

Eliza Hotchkiss, Payne Institute Director Morgan Bazilian, William Toor, and Keith Hay write about how for decades, countries, states, and municipalities have established energy policies to address local air pollution and global climate change goals. The thousands of policies and measures enacted globally take various forms but are aimed at different sectors of the economy. These policies are the result of a complicated process of analysis, budgeting, management, and politics.  This paper provides an overview of the recent legislative sessions, and how the policies enacted support the Colorado Climate Change Roadmap.  March 11, 2022.

The VIIRS Day/Night Band: A Flicker Meter in Space? 3/9/2022

The VIIRS Day/Night Band: A Flicker Meter in Space?

Payne Institute Earth Observation Group Director Christopher Elvidge, Researcher Mikhail Zhizhin, David Keith, Steven D. Miller, Researcher Feng Chi Hsu, Researcher Tilottama Ghosh, Sharolyn J. Anderson,Christian K. Monrad, Director Morgan Bazilian, Jay Taneja, Paul C. Sutton, John Barentine, William S. Kowalik, Christopher C. M. Kyba, Dee W. Pack, and Faculty Fellow Dorit Hammerling write about how the VIIRS day/night band (DNB) high gain stage (HGS) pixel effective dwell time is in the range of 2–3 milliseconds (ms), which is about one third of the flicker cycle present in lighting powered by alternating current. Thus, if flicker is present, it induces random fluctuations in nightly DNB radiances. This results in increased variance in DNB temporal profiles.  Over time, there is a trend towards the reduction of flicker in outdoor lighting through the replacement of HID with low-flicker LED sources. This study indicates that the effects of LED conversions on the brightness and steadiness of outdoor lighting can be analyzed with VIIRS DNB temporal profiles.  March 9, 2022.  

Mines to support new U.S. Department of Energy entrepreneurship program 3/8/2022

Mines to support new U.S. Department of Energy entrepreneurship program

Payne Institute Fellow Werner Kuhr, Director of the Center for Entrepreneurship and Innovation(E&I) at Mines, will support West Gate, the Department of Energy Advanced Manufacturing Office new lab-embedded entrepreneurship program, at the National Renewable Energy Laboratory. West Gate will provide mentorship and technical resources for promising cleantech innovators, and Mines will be supporting the effort with office space at the Beck Venture Center. Additionally, West Gate innovators will have the opportunity to participate in E&I programs like Innov8x, where they can pose problems that Mines students from all departments can brainstorm and help define, as well as come up with new potential solutions.  March 8, 2022.

Most Downloaded Paper Award 2021

Payne Institute Earth Observation Group Director Christopher Elvidge received the 2021 Most Downloaded Paper Award from the Journal of Environmental Management (JEM) for the co-authored article titled Light Pollution in USA and Europe: The Good, the Bad and the Ugly.  The Award recognizes papers published in JEM in a given year (2019 in this case) that received the highest numbers of downloads (Web of Science) in the following three years including the year of publication (2019-2021 in this case). Dr. Elvidge’s contribution to the scientific advancement of resources, conservation and recycling fields has been highly recognized.  March 6, 2022.

Satellite imagery shows Ukraine going dark 3/3/2022

Satellite imagery shows Ukraine going dark

The Payne Institute Earth Observation Group provided the satellite images for this article about how as Ukraine defends against a Russian invasion, lights across the country have dimmed.  Before Russian forces invaded Ukraine on February 24, nighttime satellite imagery captured the bright lights of Kyiv, Kharkiv, Rivne and other urban areas. Now that same imagery shows a country that has gone dark, steeling itself against a brutal and unprovoked military attack.  We compared the average nightly lightscape of Ukraine in January to February 25, the night after the invasion began, and found a dramatic reduction in lights across the country.  March 3, 2022.
