This is the second time I have talked about this interesting topic this month, because my electric car suprised me yesterday. I drove my car on a short trip yesterday. The place we visited only has one access road, which meandars around a mountain. I thought that it would be a challenge for an electric car, but in actual fact we got there very easily. When I checked the dashboard, it showed that it had only used 1.0 litre gas per 100 kilometres (actually my car is a hybrid car). It was a big surprise! When my car goes downhill, it is charged by gravity, when it goes uphill, the electricity powers my car. The computer system in my car is really good at using any power both from gas and nature. You know that when you step on the brake pedal in a moving gas-powered car, the extra energy from burning gas is spread into the air, which causes air pollution. But for a hybird car, the energy is collected and stored in the battery. The efficiency of using the extra energy for a hybrid car can be around 40%, But for a gas-powered car, all the extra energy wastes.So, which is better?
