This lesson covers the concept of electric vehicles, particularly in the Indian context. It discusses the benefits of electric vehicles, such as reduced pollution and decreased dependence on imported petrol. The lesson also highlights the energy efficiency of electric vehicles, which is four times greater than petrol vehicles. However, it also addresses the challenges faced by electric vehicles, such as energy storage issues due to the weight, volume, and cost of batteries. The lesson further delves into the economics of using electric vehicles, including the depreciation and interest costs, and the environmental impact of battery disposal.
