Electric Cars versus Gasoline Cars
Did you know that you can save a lot of money using an electric car instead of a gasoline car? Some people think that electric cars will not be successful because they are weaker cars, but the truth is that some electric cars have more power and speed than gasoline power. Sooner or later, gasoline cars will be history. What are the main differences between these cars that could lead to the extinction of the gasoline engine? First, efficiency, and second, emissions.
The reason that electric vehicles are a lot more efficient than gasoline cars is because their electric engine is very small and does not need oil changes and the transmission just has one gear instead of eight or ten gears. They are also more efficient because they can recycle energy. For example, when you are going down a hill or braking, the car absorbs that energy, and sends it to the main battery. Buying electricity is also a lot cheaper than gasoline, so people can save money on fuel. In the world efficiency ranking, electric cars are in the top of that list, as you know, efficiency is the key to success.
The second reason why electric cars will become highly popular is because people prefer to buy cars that are good for the environment, and their emissions are not dangerous for people and animals in the environment. Smoke and oil waste are some of the dangerous pollutants that gasoline cars are producing right now. Gasoline engines release harmful chemicals like carbon monoxide and carbon dioxide into the air constantly, so the air quality is worse because of gasoline engines. Electric cars on the other hand, do not have dangerous gas emissions or use oil, so oil pollution is also eliminated. Electric cars don’t leave smoke behind or let out dangerous exhaust. Electric cars are friends with the ecosystem; consequently they are the top one in zero pollution in the world.
In conclusion, electric cars are more efficient and produce fewer emissions than gasoline engines do. These are major differences between the two types of vehicles. These differences may lead to future changes in the popularity of these vehicles, especially as people become more environmentally concerned, or as people are looking to save a little extra money on gasoline.
