Many cars use fossil fuels, such as petroleum and diesel, to move. But now that there are machines that run on electricity it’s believed traditional cars should be abandoned. However, I think fully switching to electric cars isn’t possible for now, since the capacitances of available batteries aren’t sufficiently high for long distance coverages and they are hardly disposable.
A low capacitance lowers the distance a car can travel. Any machine in order to move has to do some work. In a combustion engine the work is done by squeezing and expanding a gas inside of a cylinder with a mix of some petrol droplets and air. This process generates way more power and the fuel can be stored in small spaces, which can’t be achieved for electricity in huge batteries. For example, on average a normal car can generate 85 kWh of energy and cover more distance than typical electric ones with 65 kWh
The batteries are not biodegradable, can be recycled, though, for a huge cost. The accumulators are made of lithium and other components and arranged in such a way that makes it hard to be taken apart and reused. These materials, compered to fossil fuels, aren’t abundant in nature. For this reason, making even more batteries without having a practical method for reusing and recycling them would firstly make it unlikelly to produce enough machines to fully replace traditional cars and secondly be too expensive.
In conclusion, due to some technological and economical limitations, the idea of fully replacing normal cars with electric ones is clearly inefficient.
