I want to talk about severals factors of electric machines. The poor autonomy is one of the major weak points of sustainable mobility, that can be resolved with the diffusion of charging infrastructure. Can be also be created stations to replace the batteries, but it would be a difficult job. In addition, the position and the form of batteries should also be standardized, since every electric machine is realized differently.
Another important issue is the cost of the electric vehicles. To decrease the costs is needed that the sustainable mobility is developed and become a widespread technology. In effect, only when the output of electric machines from the auto makers will raise, the purchase costs of these means can reach those of conventional vehicles.
The cost of batteries is high (a third of the price of the machine) and do not have a long life. Presently, it is believed that they can last around five years, then every 5 years you will have to cover a considerable expense to replace the batteries that have been depleted.
The electric vehicle can also pollute. In fact, although electric machines do not emit carbon dioxide in the air, there are other factors to take in consideration. In first place you have to know that the production of an electric mean involves some consequences on the environment, particularly with regard to the batteries, which require the use of various chemicals, such as lead or lithium.
You must also know that an electric machine has the need to be recharged and then it needs great amount of electric energy. In effect, the majority of the electric energy produced globally comes from coal plants that are highly polluting. In conclusion, we must to remember that to fill millions of electric machines we have the need to generate more energy and the more convenient and fastest way it is coal, that is a very polluting solution for the planet. The only way is the employement of alternative energy sources such as solar and wind.
Finally, an electric vehicle has a different mechanical that might lead to a loss of some professions, particularly the mechanic, that would not be required anymore. Anyway, the simplicity of its structure will decrese the number of devices and then the number of failures of the vehicle.
A company that has invested with success in electric means is the note Alke, that deals in the production of professional electric means which, thanks to their efficiency they can be used in different sectors (trade, industry, agriculture, etc..).
