TL;DR: The study revisits the position of the environmental Kuznets curve (EKC) hypothesis in India by incorporating the role of energy consumption and democratic regime in the environmental degradation function for the period 1971–2014 and finds a long-run causality between the fundamental variables and environmental degradation.

TL;DR: The results established the existence of an upward EKC dynamics, which bear a major linkage from the excessive fossil fuel energy use in South Africa and advocates the need for conservative energy policies and pollution-free energy mix.

TL;DR: In this article, the authors investigated the dynamic effect of renewable energy consumption, economic growth, biocapacity and trade policy on environmental degradation in the United States from 1985Q1 to 2014Q4.

TL;DR: Investigating the dynamic effect of oil production on carbon emissions in 15 oil-producing countries by accounting for the role of electricity production, economic growth, democracy, and trade over the period 1980-2010 found an inverted U-shape relationship between economic growth and CO2 emissions only at median and higher emission countries, validating the environmental Kuznets curve hypothesis.

TL;DR: The results demonstrate that renewable energy and energy prices exert negative pressure on CO2 emissions while trade volume exerts a robust positive pressure onCO2 emissions.
