Energy Conservation

300

What is 1 pro & 1 con to electric cars?

• Produce fewer greenhouse gas emissions compared to traditional cars, They help reduce dependence on fossil fuels, Electric cars have lower operating costs due to cheaper electricity compared to gasoline.

• Electric cars have limited driving range, Charging infrastructure is not as widespread, A higher purchase price compared to traditional cars, Electric cars may rely on electricity generated from non-renewable sources, reducing their environmental benef
