EnergyEnergy accessibility and social inequality are inextricably linked, where energyEnergy growth usually improves overall welfare and socioeconomic equality of a country. However, the impact that energyEnergy type, energyEnergy diversity, andRenewable energy renewableRenewable energyEnergy use have on countries’ socioeconomic levels has not been well understood or comprehensively analyzed. This article investigates the interconnection between energyEnergy expenditure per capita and quality of life in both the developed and underdeveloped countries. EnergyEnergy consumptionEnergy consumption per capita and inequality-adjusted human development index (IHDI) are assessed for 102 countries. The IHDI defines development in the health, wealth, and educationEducation context. Each country’s inequality coefficients are compared in the context of energyEnergy access. Also, an energyEnergy diversity factor is created to quantitatively analyze the energyEnergy diversity within a country. A general trend is found where highly developed countries not only have ample energyEnergy access but also use a high percentage of renewablesRenewable. Using these findings, a foundation for future energyEnergy policies focused on providing clean and accessible energyEnergy for societal development can be developed.
