Circular Power System: A Transformative Shift for Electrical Engineers

For far too long, the electrical power industry has operated within the constraints of the linear economy (LE) - a take make-consume-dispose model that has led to staggering amounts of waste and unsustainable resource extraction. This outdated approach is no longer tenable in the face of pressing environmental challenges and the urgent need for more sustainable practices. The time has come for electrical engineers to spearhead a fundamental shift towards a Circular Power System. I first coined this phrase Circular Power System in my Ph.D. thesis[1] and explored novel applications considering the technological changes as well as social sciences landscape in the power and energy sector[2]. Later, this concept even got picked by practitioners in industry and eventually resulted in white papers. Very recently, we have heard about the electric power sector going circular from companies like Mitsubishi[3], PwC[4], and Enel[5]. The key focus was on improving resource efficiency throughout the value chain by promoting recycling, use phase extensions, and product substitution by a service.

If we explore this in a more detailed way, firstly, the linear economy has resulted in a concerning accumulation of waste from decommissioned power system components, such as solar panels, wind turbines, and batteries, sometimes even the traditional energy assets also fall under this category. Rather than simply disposing of these materials, the Circular Power System approach emphasizes the importance of recycling, reuse, and extending product lifespans. By closing the loop on resource flows, electrical engineers can significantly reduce waste and mitigate the environmental impact of the power sector. Secondly, the LE model is exacerbating the problem of dwindling resource availability. As global demand for energy continues to rise, the strain on finite natural resources is becoming increasingly unsustainable. The Circular Power System approach offers a way to address this challenge by promoting more efficient resource utilization, material substitution, and the development of innovative technologies that enable or even facilitation of the reuse and repurposing of power system components[6]. Furthermore, the transition to a Circular Power System aligns with the growing momentum towards sustainable business models and the widespread adoption of the circular economy (CE) concept. While CE principles have been slowly trickling into the power and energy sector, the time has come for a more concerted and comprehensive effort led by electrical engineers. By pioneering the Circular Power System, electrical engineers can position themselves as champions of environmental stewardship and catalysts for a more circular future that is sustainability and resilience. This research direction holds the potential to transform the industry, minimize waste, optimize resource use, and ultimately, pave the way for a more resilient and environmentally responsible power
infrastructure.

The speaker's early work in coining the term "Circular Power System" and exploring its novel applications underscores the importance and timeliness of this research direction. As the power sector embraces the circular economy, electrical engineers must seize this opportunity to lead the way towards a more sustainable and resource-efficient future.
