@onedaysoonish you are correct. Any form of electrical energy storage is a conversion from another form of energy beit solar (via photovoltaic cells), mechanical (via turbines). There is an efficiency with conversion from each form of energy to another. This means that you never end up with the same amount of energy that you started out with. New EV technologies are coming out all the time. We used to have Lead-Acid cells, then we got Ni-Cd, then we got Li-ion. The latest thing is storing electrical charge with capacitors and slow release. Combined with superconductivity where some alloys when supercooled will continue to flow current when the current is removed (don't ask me about the fine detail of this) are in the future. But fossil fuels continue to hold a high amount of energy per unit mass and this is their attractiveness in applications where low weight is essential (aerospace, space, etc.) We are progressing towards technologies which are comparable but some way off. Additionally, oil (and it's distillates) are requried to produce many chemicals and so demand will continue for some time.
