Kim: Some people claim that the battery-powered electric car represents a potential solution to the problem of air pollution. But they forget that it takes electricity to recharge batteries and that most of our electricity is generated by burning polluting fossil fuels. Increasing the number of electric cars on the road would require building more generating facilities since current facilities are operating at maximum capacity. So even if all of the gasoline-powered cars on the roads today were replaced by electric cars, it would at best be an exchange of one source of fossil-fuel pollution for another. The main point made in Kim's argument is that ['gasoline-powered cars will probably remain a common means of transportation for the foreseeable future', 'a significant reduction in air pollution cannot be achieved unless people drive less', 'replacing gasoline-powered cars with battery- powered electric cars will require building more generating facilities', 'battery-powered electric cars are not a viable solution to the air-pollution problem']
