Comparison of typical electric and petrol cars |
Social sustainability is about meeting people's needs.
Electric cars are not as fast as petrol cars. They have a short range before their batteries need to be re-charged (which takes 5-6 hours). Practically, electric cars can only be used for short journeys inside cities.
Petrol cars are faster, easier to re-fuel and generally a lot cheaper than electric cars.
The current technology means that electric cars are not popular.
Manufacturers cannot afford to make them if they will not sell. |
