Oil will not last forever—that’s a fact everyone knows. So what can make the cars run instead of that? Well, there are two options: electricity and natural-gas. In the 79th International Motor Show at Geneva, there were examples for both.
My personal favorite is the Dodge Circuit EV; even journalists were given one of these to try out for three days (check this link for details). Using electric motor only, these cars have no CO2 emission at all. They are a little expensive to buy, but there is no added cost of refueling. Here is a list of electric cars that will be or already are available for purchase.
The other group was the natural-gas power. This is similar to gasoline, but first, it is 20-30% cheaper. Second, it has a negligible CO2 emission that has absolutely no effect on the climate. There are already a growing number of these in Switzerland; you can read more about these here.
I can only hope that the change from gasoline to alternative fuel will take place in my life.
