Tackling economic policy uncertainty and improving energy security through clean energy change

In the present economic environment, economic policy uncertainty is one of the most critical concerns, which can adversely affect the economy and prevent sustainable development simultaneously. Energy security is an essential factor that affects the stability and well-being of a country. In this regard, through clean energy change, governments can work on these two challenges to enhance energy security, stimulate the economy, and manage the effects of climate change. This paper examines the link between policy uncertainty, energy security, and cleaner energy transition in BRICS countries from 1990 to 2021. This research seeks to use fossil fuel energy consumption and renewable energy consumption as control variables. The evidence reveals that institutional factors such as economic policy uncertainty and energy security are linked to promoting clean energy transitions. On the other hand, fossil fuel's historical and current use reduces such change, while renewed resources have the opposite effect. Therefore, economic policy uncertainty and energy security deserve enhanced attention from policymakers if the efficient transition to clean energy is to be achieved across the BRICS nations. BRICS countries are advised to invest heavily in renewable energy technologies and diversify their energy sources to improve energy security and reduce economic uncertainty.
