The influence of renewable energy use, human capital, and trade on environmental quality in South Africa: multiple structural breaks cointegration approach.

Recent economic and environmental literature suggests that the current state of energy use in South Africa amidst rapid growing population is unsustainable. Researchers in this area mostly focus on the effect of fossil energy use on carbon (CO) emission, which represents only an aspect of environmental quality. In contrast, the current study evaluates the influence of renewable energy use, human capital, and trade on ecological footprint--a more comprehensive measure of environmental quality.
