What are the advantages and disadvantages of new energy vehicles?

Advantages of new energy vehicles: 1. Low usage cost: The electricity cost per 100 kilometers is about 8 yuan, similar to the price of 1 liter of fuel; 2. No license plate restrictions: In large cities where license plate restrictions are common, new energy vehicles do not have this issue; 3. Smooth driving: No gear shifting impact. Most new energy vehicles use single-speed transmissions, eliminating gear shifting impact; 4. More environmentally friendly: Contribute to environmental protection efforts; 5. Saves fuel energy: Typically powered by natural gas, petroleum gas, hydrogen, or electricity; 6. Reduces exhaust emissions, effectively protecting the environment: Electric vehicles produce no exhaust and no pollution; hydrogen-powered vehicles emit only water, causing no environmental pollution. Disadvantages: 1. Slow charging: As new energy vehicles are still in the early stages, the technology is not yet mature. Charging is relatively slow, taking several hours. 2. Low vehicle ownership makes charging, refueling, and maintenance less convenient: Charging is difficult due to limited popularity. 3. Short driving range: Generally, the vehicle displacement is small, with insufficient power, making them unsuitable for long-distance travel. 4. High price: Currently, new energy vehicles priced between 50,000 to 100,000 yuan are mostly pure electric vehicles with limited production options.
