Much is said about electric vehicles save the environment; however, it should be taken into account that, for example, the energy matrix of Europe uses a significant amount of mineral coal and fossil fuels. In order to speed up electrification, CO2 emissions will be increased in procedures prior to the use of electric vehicles. At the same time, in Brazil there is an equally interesting approach to the conservation initiative: alcohol machinewhich is often less polluting than the process to make an electric car viable on the European continent.

Many are waiting for electric cars accelerate the energy transition matrix, which means that in the long term, emission reductions will be tangible, but this is still not an easily predictable scenario. Electric motors are actually less polluting, but emissions prior to this stage should not be ignored. Coal fired power plants are an important part of the process.

Alcohol car used in Brazil and environmental benefits

alcohol machine emits CO2 during combustion, but the CO2 captured by the sugarcane still in the field compensates for this characteristic. Unlike European electrification, the path between the field and the vehicle produces other important resources such as chemicals, sugar and others. Sugar cane waste is equally important in the production of second-generation ethanol, and even incineration.

This procedure is considered more suitable for environmental protection efforts than zero emission technology, however, in order to achieve its final form “dragproblematic. Does this mean that the ethanol car used in Brazil is less polluting than many electrification-based alternatives? In some cases, yes.

In this way, all points explained indicate that Brazilian realities offer more alternatives. The path to transition to low-emission energy can be achieved by other paths than those taken by the major powers. – in the end, the technologies of electric vehicles are interesting, which significantly reduce harmful emissions; however, procedures prior to the final technology should not be ignored.
