Environmental protection is still not environmentally friendly, we can look at the data.
“Electric vehicles mean green, meaning low-carbon, electric vehicles are synonymous with environmental protection. Now the global climate is warming and the haze is so serious. It is a merit for Tesla BYD to do electric vehicles. This is saving the earth. Save human beings balabala..." We often hear the electric car supporters around us send such "Amway". On the surface, all electric cars are powered by electricity, do not emit any exhaust gas, and seem to be very green and low carbon. However, a recent online commentary program in the United States disagreed with this point of view and used a whole program length to discuss "electric cars are not as green as you think."
"Adam Ruins Everything" is an online commentary program in the United States that specifically refutes ideas that people take for granted, exposing scams created for commercial purposes and having a strong influence on the US Internet. force.
In the latest installment, host Adam Conover explained to more than 11 million viewers that "electric cars are not as green as you think." He used Tesla as an example to elaborate on why electric vehicles are not environmentally friendly. In fact, the fossil fuel industry has attacked electric vehicle companies for many years from his point of view, which makes us have to doubt whether Adam Conover is impure.
Adam Conover throws a more "special" view, which is also a long-standing view of traditional car companies: "you are just shifTIng emissions from the tailpipe to the power plant." - (buy electric cars) just put The exhaust from the car was transferred to the power plant.
This view seems to be very reasonable, but it does not explore the facts, always thinking about making a big news. When people look at it, they will take it for granted that the pollution of electric vehicles is more serious than that of traditional vehicles, because power plants have always been a big source of pollution.
Is that true? Let's take a look at how Tesla CEO Elon Musk looks.
At the TED conference two years ago, the host asked Musk: At present, the large share of power generation in the United States depends on fossil fuels. What is the significance of your electric vehicles? The meaning of the above is similar to that of Adam Conover above. .
Msuk was shocked and it was not easy to find the problem. Ha, actually, Musk calmly gave his answer:
“The same type of fossil fuel, such as natural gas, will be sent to the power plant to generate electricity, which will have a comprehensive combustion efficiency of 60%. However, if it is placed in a natural gas-filled internal combustion engine, the highest comprehensive combustion efficiency so far is only 20%, even Considering the loss of electricity during transmission, the electric vehicle plus power plant mode also has obvious advantages for direct combustion of the internal combustion engine, which does not consider the energy consumed by gasoline, diesel and natural gas from the oil refining process. In addition, wind power hydropower solar energy The use of these sustainable energy generation methods has been a significant increase in the utilization of energy. In other words, they account for a larger share of the total power generation, and the combustion efficiency of internal combustion engines has increased many years ago. I have encountered a bottleneck."
This last sentence made the traditional car manufacturers feel full of malice. So is Elon Musk lying about selling electric cars? Is his data true?
A notice from the Xiamen Energy Conservation Center entitled "Comparative Energy Conversion Efficiency between Pure Electric Vehicles and General Motors" seems to support Musk's point of view:
"The efficiency of the traditional internal combustion engine is 38%. Because of the frequent parking and low-speed driving of the car in the city, the internal combustion engine is idling or in the low-efficiency zone. The final efficiency is only 12%. The inertia of the electric vehicle is idle when parking. More than 95% of the battery energy can be converted into the power of the car. Even considering the power generation efficiency, power transmission and distribution efficiency, and battery charging and discharging efficiency of crude oil, the final efficiency can reach 19%.
In this way, although the thermal power plant is very polluted, the overall combustion efficiency is still more environmentally friendly.
In addition, foreign media Greentech Media survey shows that in the United States, 30% to 40% of consumers who purchase electric vehicles install solar panels at home, further reducing the pollution of the use of electricity to the environment, which is far from Higher than the general population. In other words, electric car owners are generally more environmentally conscious.
Well, electric car fans can safely drive their own electric cars to fly, electric cars are not as environmentally friendly as diesel locomotives? Nothing!
