To make electric cars truly attractive for the future, the electricity for them must come from local renewable sources of energy and a way can be found to recycle the batteries. For example, approximately 27.4 gallons (104 liters) of oil are required to produce four tires for an electric vehicle alone. These also cause CO2 emissions and can quickly lead the energy balance of a "clean" electric car into the negative. What should not be forgotten, however, is the amount of energy - as well as their origin which is necessary for the production, transport, sale and disposal of electric vehicles and their batteries. The advantages of electric cars are, above all, their efficiency, their almost emission-free performance as well as their torque characteristics. Currently, however, the chargeability of such batteries is still limited to about 16 kWh, which corresponds to a range of approximately 62 miles (100 km). These are convincing in comparison to other accumulators by a lower self-discharge as well as a higher power density. At present the batteries mainly used are lithium-ion batteries.
The issue of electricity and mobility is not just the question of the presence of sufficiently large quantities of clean electrical energy but also the amount of raw materials required for around 800 million car batteries. If the distance between the dam, the solar park or wind turbines and the place where the electricity is needed is too far, it will result in a huge loss of energy. However, the distance between production and destination must be considered. For it to be attractive as an energy form, it must come from renewable energy sources.Įlectricity is suitable to transport electrical energy. Electricity thus appears to be the future of mobility.īut many people forget that electricity is not a source of energy but merely a form of energy. Especially in the USA - and increasingly also in this case - these vehicles are very popular. These combine conventional combustion units with electric motors and are thus something like the precursor to pure e-mobile. Every major automobile manufacturer now has at least one hybrid model in its vehicle portfolio. Especially in the automobile sector, there seems to be no getting around electricity neither now or in the foreseeable future. In the eyes of the public, electrical energy is the great alternative to petroleum par excellence.
