Clear results were achieved from studying the electric power generation mix of renewable, coal, natural gas, nuclear, etc., across the nine selected nations (USA, Turkey, Japan, India, China, Brazil, Morocco, Chile, South Africa) from 2000 to 2021. That gave data and specific indicators that can be cross-examined with other research for comparison value and fact-checking. In addition, comparing the carbon intensity of BEVs across different national grids, identifying which countries achieve the greatest emissions reductions, gave us useful insight into the situation of each country. That gave way to assessing the potential for future emissions reductions in each country based on projected changes in their electricity generation mix over the years.46enCarbon emissionBattery electric vehiclesEnergy efficiencyEnergy conversionEnvironmental ScienceHozzáférhető a 2022 decemberi felsőoktatási törvénymódosítás értelmében.
