As for now, I think the presence of electric vehicles will not be a great threat for the oil industry because only a few electric vehicles are being produced added by the fact that many people tend to use vehicles that uses oil because electric vehicles are time consuming when it comes to charging although there are solar panels but still oil generated vehicles can do a lot of works compared to electricity generated vehicles so it is not that much threat for the oil industry on the other hand of it, I am thinking that those two features will be fused as one so that when a vehicle runs out of oil, it will still function because it has a feature of being electrically powered to still start working even without oil.
