Global export flow of Chilean copper:The role of environmental innovation and renewable energy transition

Copper is one of the most important minerals that has extensive use in environment-friendly technologies and renewable energy generation.The global urgency for environmental and ecological conservation through renewable energy transition has considerably enhanced the importance of copper and articles thereof.Chile is a major producer of copper.It contributes more than one-third to global supply.Therefore,this study explores the export flow of Chilean copper in response to increasing demand side conditions in major 24 trading partners from 2002 to 2020.This objective is realized by constructing an augmented model for import demand that incorporates bilateral real exchange rate along with real GDP,environmental innovation,and renewable energy transition in major import markets.The estimated results of panel quantiles via moments techniques reveal a significant positive impact with increasing coefficients at higher quantiles,while environmental innovation and renewable energy transition in trading partners show significant positive impact with decreasing values of coefficients at higher quantiles.The findings urge Chile to enhance production capacity of copper and other critical mineral and improve participation in global value chain to meet sharply increasing copper demand from environmental innovation and renewable energy transition.

Impacts of nuclear energy,greener energy,and economic progress on the load capacity factor:What we learn from the leading nuclear power economies?

The worldwide tremor of environmental degradation commonly represents the escalation of emissions levels and ecological footprints that harm the planet’s biocapacity.This is because of using gigantic non-renewable energy resources,urbanization stream and massive economic activities in the major industrialized nations.Amid this situation,we investigate the influence of disaggregated energy measures,e.g.,renewable,and nuclear energy,income growth and urbanization on the load capacity factor(biocapacity divided by the ecological footprint)of major nuclear power countries,such as France,the USA,Canada,China,and Russia during 1990-2021.To this end,we utilize the CS-ARDL procedure because of the endogeneity,common correlation,non-stationarity in data and heterogeneity in panel units.We contribute to considering the supply side dynamic of environmental degradation parameter,the load capacity,from the perspective of the top nuclear power nations that deviates our analysis from the prevailing scholarly works.However,our findings confirm a significantly positive impact of renewable and nuclear energy on the load capacity factor in improving environmental safety.Besides,economic growth and urbanization negatively affect the load capacity dynamics in spurring environmental degradation.Our findings are robust across an alternative estimation technique,namely the Dumitrescu and Hurlin(DH)causation analysis.Therefore,we recommend formulating pragmatic policies to deter the detrimental effects of income and urbanization by properly utilizing sustainable energy resources to conserve the natural environment.
