Now the development of many companies has stalled at using traditional energy resources like coal. For many years they have been high-consumption, high-emissions and low-productivity energy sources. The environmental problems we're facing are getting more serious every day.

That's right, those heavy-polluting firms release so much polluted water and waste gas every day, seriously polluting what was once the blue sky and crystal-clear water, should have been dealt with long ago.

Think about it. First, coal-fired power plants do not only emit carbon dioxide, but also other harmful gases; for example, nitrogen oxide and sulfur dioxide. The amount of emissions from these harmful gases is much higher than what comes from gasoline cars. Secondly, the damage to the environment is greater when manufacturing electric cars. First you need to produce a lithium battery. The volume of these lithium batteries is huge, so it is costly to manufacture them. Tesla's batteries are even more expensive as they are bigger and stronger than the competitor's. Many electric car batteries use rare earth elements, that are scarce, and which are costly to extract. Tesla's AC induction motor doesn't use rare earth materials, but the company's engineer also admits that when producing Model S cars, the consumption of energy is more than for a Camry. Therefore, in the beginning, before you get on the road, Model S cars have already caused much more severe pollution that other cars. The longer you drive it, the greener it will then become.

Whether it is environmentally friendly in the end or not, I still think people will have differing viewpoints. If you view it from the long-term, perhaps it is fairly green; but for the present, it isn't that green. Electric cars don't burn gas, so they are quite green. That's true. There is no engine, no gas tank, no exhaust emission. It has basically zero emissions. But if you consider the effect of the car on the environment, you can't just look at exhaust pipes. Tesla doesn't run on air, it uses electricity. And electricity comes from different fuels: for example, nuclear power, natural gas, and coal, which pollutes the environment the most.

Haha, you could understand it that way. When you drive this car, you're using the engine's power and what's being burned is gas. But then, when you're waiting at a red light or stuck in a traffic jam, the power is supplied electrically. This way, you not only save fuel, you're also reducing exhaust emissions in a major way.

Environmental pollution is definitely a serious problem these days. But the government has consistently done more to strengthen its protection of the environment. Recently, a lot of chemical companies were closed to reduce the release of pollution. The country has also put a lot of financial resources into developing water purification and recycling systems to solve the problems of water pollution and shortages. And then there's all kinds of ``greening," and measures to protect the ecological environment are getting started. That goes to show that everyone takes environmental protection more seriously all the time. I think that as common citizens, I think we just need to take care of our own business. You can count that as making a contribution to environmental protection.
