Virtual Energy, Joel B. Eisen, Felix Mormann, Heather E. Payne Jan 2024

Virtual Energy, Joel B. Eisen, Felix Mormann, Heather E. Payne

Faculty Scholarship

From employment to education, many areas of our daily lives have gone virtual, including the virtual workplace and virtual classes. By comparison, the way we generate, deliver, and consume electricity is an anachronism. And the electric industry’s outdated business model and regulatory framework are failing. For the last century-and-a-half, we have relied on ever larger power plants to generate the electricity we consume, often hundreds of miles away from the point of production. But the outsized carbon footprint of these power plants and the need to transmit their output over long distances threaten the electric grid’s reliability, affordability, and long-term …

Feminizing Decentralized Renewable Energy Programs: A Study Of A Community Renewable Energy Project From India, Aritra Chakrabarty Jul 2023

Feminizing Decentralized Renewable Energy Programs: A Study Of A Community Renewable Energy Project From India, Aritra Chakrabarty

Michigan Tech Publications, Part 2

The increasing impact of global forces on local communities in the 21st century has necessitated a shift in focus from macro narratives to the micro-politics of planning. One of the critical areas of such micro-politics is energy policy-making in the Global South. It is argued that a bottom-up approach to energy intervention would increase the control and access of the end consumer to the sites of production, shift away from colonial energy production systems, and create more avenues for equitable community development. Within this context, this study critically evaluates a community-based renewable energy project from a feminist perspective. The study …

Research outputs 2022 to 2026

Bangladesh’s railway system mostly uses typical manual railway crossing techniques or boom gates through its 2955.53 km rail route all over the country. Accidents frequently happen at railway crossings due to the lack of quickly operating gate systems, and to fewer safety measures at the railway crossing as well. Currently, there are very few automatic railway crossing systems available (without obstacle detectors). Additionally, all of them are dependent on the national power grid, without a backup plan for any emergency cases. Bangladesh is still running a bit behind in generating enough power for its consumption; hence, it is not possible …

As governments and non-state actors strive to minimize global warming, a primary strategy is the decarbonization of power systems which will require a massive increase in renewable electricity generation. Leading energy agencies forecast a doubling of global hydropower capacity as part of that necessary expansion of renewables. While hydropower provides generally low-carbon generation and can integrate variable renewables, such as wind and solar, into electrical grids, hydropower dams are one of the primary reasons that only one-third of the world’s major rivers remain free-flowing. This loss of free-flowing rivers has contributed to dramatic declines of migratory fish and sediment delivery …


Assessing Compressed Air Energy Storage (Caes) Potential In Kentucky To Augment Energy Production From Renewable Resources, J Richard Bowersox, John B. Hickman Jan 2023

Assessing Compressed Air Energy Storage (Caes) Potential In Kentucky To Augment Energy Production From Renewable Resources, J Richard Bowersox, John B. Hickman

Report of Investigations--KGS

Fossil fuel power plants in Kentucky have some of the highest emissions of greenhouse gasses in the United States. One potential strategy for mitigating greenhouse gasses from electric power generation is the co-installation of Compressed Air Energy Storage (CAES) and a renewable source such as photovoltaic solar electricity generation (PV solar generation). CAES with complementary co-installed PV solar generation enhances stand-alone PV solar generation because CAES power is available at night.

CAES, however, requires both a site where large volumes of compressed air can be stored in the subsurface, and a heat source to prepare the stored air prior to …

Meeting Clean Energy Goals Will Require The Grid Of The Future, Ken Berlin, Rob Gramlich, Alexandra B. Klass, Josiah Neeley

Articles

The transmission grid is the critical superhighway that connects energy supply and demand. But our grid was designed for the power plants of the past—not for the diverse range of resources and technologies of our clean energy future. Over 70 percent of the nation’s transmission infrastructure is more than 25 years old, and in many areas of the country constraints have already been an impediment to renewable power. To meet greenhouse gas reduction goals, we will need to expand electric transmission systems by 60 percent by 2030 and possibly triple the capacity of these systems by 2050. The Infl ation …
