Electric and plug-in hybrid vehicles in a European region mainly rely on electricity stored in batteries for power. The key focus is on how this energy is produced, as if it's mainly from not-so-environmentally friendly sources, electric cars might not be as eco-friendly as they seem. The research looks at the current charging options like home or public charging stations in Central and Eastern Europe, highlighting the importance of sustainable energy production for electric vehicles to truly be green alternatives to regular cars. Issues like building charging infrastructure and recycling used batteries also play a role in shaping the future of transportation in the region.
