The real blocker of going electric on everything is the capacity of rechargeable technologies and their lifetime, not some global conspiracy. Even the high price of batteries/capacitors might not be a problem if lifetime and capacity would be great. In that sense Musk might be onto something, but I think it takes a lot more than 20% improvement over current technologies for batteries to become feasible for storing electricity on large scale. If a smartphone could be done with a battery, that lasts a week and is not dead within a year in winter conditions, it probably would have been done allready.
