21 Critical thinking of electric car sustainable development

Following the electric car and energy company, Tesla sold the Model S electric car, the electric vehicle becomes a hot topic for the general public. It is necessary to consider the future development of the electric vehicle, whether it is really environmentally friendly. 

Today, I only talk about the electric car, no other type of vehicles. There are two types of the electric car, one is the fuel cell cars and the other is pure electric cars. First and foremost, the fuel cell cars have more energy conversion links, and the pure electric cars dominate energy conversion efficiency. A pure electric car needs 20 mins even if it is fast-charged, and the hydrogen-fuel car will be hydrogenated for 5 mins, and the fuel cell vehicle dominates from the energy supply rate. However, the fuel cell cars are faced with difficulties in hydrogen production, transportation, storage, and manufacturing of low-cost fuel cells. At present, Japanese engineers and other companies are making great efforts to research and develop technical accumulations and barriers. In addition, pure electric cars have many difficulties in terms of battery life. Nowadays, most countries are taking the electric vehicle route, and a large number of scientists and companies are making technical breakthroughs. 

Whether it is really environmentally friendly? I think it isn’t now, but it will in the near future. Many countries, including the United States, mostly use fire thermal power. Coal is the main source of electricity. Well, in fact, it is a process that generates electricity by burning coal, then charges electric vehicles, and then converts electricity into power. Regardless of the efficiency of sub-transformation, coal mining and coal burning must have a negative impact on the environment, so that the American investment risk writer Vinod Khosla said: The so-called electric vehicles are actually coal-powered cars. However, the sources of electricity are diverse, including wind, hydro, solar, hydrogen, bioenergy, geothermal, and nuclear. As above, some seem to be environmentally friendly, and the level of existing technology cannot be ignored. In short, no matter where it comes from, the “fuel” of electric vehicles must be clean.


In conclusion, one-third of the CO2 emissions of an electric vehicle is equivalent to the life cycle emission of a gasoline vehicle. This may be a bit exaggerated, but it is an indisputable fact that electric vehicles need to break through many bottlenecks.
