In India, researchers are looking into using renewable energy like solar and wind power to charge electric vehicles in smart cities. They want to reduce pollution and CO2 emissions by combining solar panels and EVs to charge the vehicles. By using renewable energy sources at charging stations, they aim to cut down on harmful gases and increase energy efficiency. This can help in extending the reach of electric vehicles, which are cars that run on electricity stored in batteries. The study suggests that combining solar or wind power with EVs can lead to a more eco-friendly way of charging vehicles in India.
