| Electricity must produce somewhere |
Kimmo Huosionmaa
Many times before I have written about technology, what is used in electric cars, and why those cars are ultimate challengers for normal cars. But as you know there is no product, what is without environmental problems. Here come the critics against electric cars, what somebody has been waiting. There are a couple of environmental problems with electric cars, and one of those problems is, what happens to used batteries, and in those vehicles is used many synthetic materials. So what would those wrecks happen, when they are removed from traffic? They are similar wrecks as other cars, and that makes them problematic for the environment, and those composite materials are hard to recycle.
So here I must say that the electric motor would just transfer the pollution to another place, and if the electricity would not produce by using clean methods would the environment load of that car even bigger than the normal car. The major problem is, that electricity must produce somewhere if it wanted to use in cars, and that would increase the need to build more power plants. And that is very bad for the environment. In this case, I'm talking about the situation, that the electricity would be produced in some power plant, what uses brown coal to make the electricity. Or that would not have properly cleaning systems for the smoke gases. Electric cars have also environmental problems, and that means they are not without problems.
That type of vehicle would not create pollution itself but producing the electricity makes pollution, and this is the biggest problem with electric cars. Some persons, who argue against electric cars says that in those devices the pollution is just transferred to another place like power plants, and that's why the environmental load, what those devices causes are even bigger than normal cars, what uses the gas or some other environment-friendly combustion fuel.
If the power plant would use some dirty stuff as the fuel, the environmental load will be very big, and if we are talking about the environmentally friendly way to use automobiles, the only way to make that true reality is to use fuel-cells, what are using hydrogen and oxygen, what is produced by using solar power or Earth thermal systems, what is environmentally friendly way to produce electricity for electrolysis. But there is another thing, what causes problems with electric cars in the city environment. That is the loss of space and parking areas.
The problem with cars is that they are one of the most dangerous things in the city area. If the driver is drunk, there are many people, who are in danger in the area of the car. And the limited road capacity is problematic for every car in the city area. The electric car has also problems with the battery waste. This waste is sometimes very toxic and involves the heavy metals like cadmium, what makes those waste very problematic.
Over one hundred years the city areas are made for first the carriages and then this advantage turned straight to the cars, and the most important point of view in the environment-development was, that the cars were allowed to come near people and markets doors. And this is now visible in the loss of space. Here are too many cars in the city areas, and this is the thing, what we must realize.
