Here in my Country the most economic option for the vehicles is the use with GNC (compressed natural gas). But really it's economic becauseis the same gas of the houses, that is compressed in the gas stations, which has the price subsidized by the government, and autonomy does not exceed 200 km.

The problem for purely electric vehicles in my country is that the electrical supply to the homes, it is not very safe and every so no interrupts, especially when there are very high or very low temperatures.
The other problem is if used as the only vehicle, due to long distances, it is impossible to use it to go on holiday to points far from cities.
