The future of cars is electric

I have no doubt about it, although there are still some who maintain resistant and deny the evidence of climate change and defend fossil fuels. Every day they are less but they are still very powerful and they have money and means of communication at their expense to expand their theories.

The main reason is very simple, the electric motor has an efficiency of 85% compared to 15% of the explosion motor. Those who deny this future argue, among other reasons, that if an electric car is charged with “dirty” coal energy, it pollutes. This is true, but even in this hypothetical case, the superior efficiency of the electric motor would make better use of the energy generated.

Arguing with the denialists makes no practical sense, they have their preconceptions and particular interests (those of the oil companies that support them) and will defend them to the end.

On our planet there have always been changes in climate, and it is true that a certain warming is taking place naturally, which worsens very significantly with the pollution we generate. Then we have to take concrete actions.

I have read (I do not know to what extent it is true) that in the beginning of the automotive industry at the beginning of the 19th century, electric cars emerged in the USA as well as an explosion engine.

But over time those of explosion prevailed due to their ease of refueling. In the electric cars the batteries had to be interchanged and that was a nuisance.

More than 100 years later, we return to the same dynamics, with the exception that electric vehicles have a greater range today, and recharging times are decreasing, although much remains to be improved.

Despite what those that are ill omened say, with the electricity grid installed today it could charge between 50 and 70% of the cars if they were all electric, and they could be charged at night, which is when more energy is left over.

It is not a network problem, but rather having sufficient charging centers close to the needs of users.

I have not quoted anything about the hydrogen powered car because it is less efficient than electric, with an efficiency between 30 and 50%.

I am clear that the future is electric, but it will take time to arrive because there are many and powerful interests interposed, and because changes are never rapid. I do not know if the Covid-19 will encourage some to change their lives and their cars.
