POLLUTION AND ELECTRICITY

Pollution and electricity
In 2009, the transport sector was blamed 39 percent of final energy consumption in Spain, with an energy intensity by more than 40 percent of the European average (EU-27). The transport sector remains heavily dependent on petroleum products (98 percent). In the case of road transport, it represents more than a quarter of total CO2 emissions by 25.4 per cent -the Spain, accounting for around 80 percent of energy consumption in the transport sector and 90 percent of its CO2 emissions.

From an environmental perspective, there is no doubt the effectiveness of electric vehicles, both to reduce the emission of greenhouse gases and to reducing both local air pollution and atmospheric sonora.2

Contamination of any vehicle (electric or not) should be accounted for by adding the direct emissions, which are emissions produced by the engine of the vehicle itself, and indirect emissions, which are emissions produced in systems outside the vehicle but fundamental to this by providing the energy required for operation. Although an electric vehicle produces no emissions during operation, the generation of electrical energy required to move the electric vehicle emissions results and the consumption of non-renewable resources to a greater or lesser extent, depending on how the electricity has been generated , as was seen above. A particular case is that of vehicles using renewable electricity as a source of primary energy (this is the case recharged by solar electricity, vehicles also known as a solar-charged vehicle). Also, during the generation, transmission and transformation of electricity of the energy it is lost, so the useful energy is below the primary energy, as seen before. The same applies to oil, in addition to transport costs due to the geographical difference of places of production and consumption, we need to transform refineries in different petroleum products, including fuels.
