Legal responses to energy security and sustainability in Nigeria's power sector amidst fossil fuel disruptions and low carbon energy transition.

Fundamentally, energy could be refer to as the cornerstone for progress of most nations, as a lack of unswerving energy sources perpetuates poverty and impedes economic development. In Nigeria, there exists an abundance of low-carbon energy resources that hold immense potential for fostering sustainable growth. Regrettably, Nigeria has yet to fully harness these resources to drive its economic expansion and bolster its power sector. This study undertakes a thorough exploration of the untapped capacity of low-carbon energy bases in the country, with the aim of ensuring a consistent and dependable electricity supply. The research methodology employed in this study encompasses both empirical and doctrinal legal research approaches, drawing upon a wide range of primary and secondary sources, including authoritative energy law textbooks and peer-reviewed journals. In order to gain valuable insights into achieving a stable electricity supply in Nigeria, a meticulous comparative legal analysis of low-carbon energy practices was conducted, focusing on the experiences of China, Spain, Germany, and Nigeria. By applying legal theories and empirical procedures, the study estimated carbon emissions using the auto-regressive distributed lag model. The data exploited in this study were acquired from the World Bank's World Development Indicator (WDI, 2021), a renowned public domain repository of economic development data encompassing numerous countries worldwide. The findings of this study demystify the positive association between electricity consumption and substantial fluctuations in CO2 emissions, as demonstrated by both short-run and long-run model estimations. Significantly, the presence of hydroelectric power sources emerged as a pivotal factor in curbing carbon emissions. Moreover, the study's error correction model findings unveil a noteworthy mechanism of systemic convergence when confronted with external shocks. To facilitate the adoption of low-carbon energy sources, the study proposes a hybrid model that combines various approaches, while underscoring the urgent need for reforming Nigeria's energy laws to address environmental concerns and promote security and sustainability. The practical implications and policy applications of this research highlight its potential to provide policymakers in Nigeria and beyond with invaluable insights for formulating effective measures aimed at reducing carbon emissions arising from electricity generation and consumption.
