The objective of the present study is to explore the impact of public-private investment in energy, foreign direct investment, urbanization, and renewable and non-renewable energy consumption on environmental degradation in major investment countries during the period 1998Q4-2018Q4. In doing so, the cross-sectional dependence test and CIPS panel unit test were employed to identify the cross-sectionally dependency and the integrational properties/stationarity among the variables. Furthermore, we opted for Westerlund (2007) panel cointegration test to check the long-run association among the variables.

The present paper investigates the effects of hydropower energy consumption on economic growth and CO emissions in the BRICS countries, spanning the period 1990-2016. To achieve this aim of the study, we employ the panel autoregressive distributed lag (ARDL) model and panel quantile regression (PQR) estimations. The results confirm that hydropower energy consumption has a positive association with economic growth in the long run and short run, and negative association with CO emissions in the long run.

For the last three decades, both China and India are considered as the largest emerging market economies in the world. Both of these economies play an essential role in the global economy in terms of economic output and CO emissions. Hence, these countries are expected to play an important role in setting up environmental and sustainable development policies.

The present study empirically investigates the impact of hydropower energy consumption on economic growth and CO emissions in China, spanning the period 1965-2016. Using the ARDL bounds testing approach to cointegration, this study confirms the existence of a long-run relationship among the variables. Moreover, hydropower energy consumption has a positive impact on economic growth, while CO emissions have a long-run negative impact on economic growth.

This study aims to examine the impact of renewable and non-renewable energy consumption on the agriculture, industry, services, and overall economic activities (GDP) across a panel of G20 nations. The study makes use of annual data from 1980 to 2012 on 17 countries of the G20. To achieve the study objectives, we apply several robust panel econometric models which account for cross-sectional dependence and heterogeneity in the analysis.
