This thesis investigates the impact of access to clean energy on the Human Development Index (HDI) across 24 countries over the period from 2010 to 2021 in East Asia and Pacific region. The study uses panel data analysis to explore both the direct effects of clean energy access and the broader implications for human development. The primary aim of this research was to assess the correlation between HDI and energy access, specifically determining whether increased energy access contributes significantly to human development. Additionally, the study sought to identify the most influential independent variables affecting HDI and ensure the findings' robustness through various econometric tests. Unit root tests indicated that the variables were stationary, justifying the use of panel data techniques. Pedroni's cointegration test confirmed an extended timeline balanced relationship between HDI and access to energy, highlighting the sustainable impact of energy access on HDI. The analysis was conducted using panel data techniques, employing both FE and RE models to control for unobserved heterogeneity among the countries. The different models revealed that access to energy has a comprehensive beneficial and statistically relevant effect on HDI.
