Experts, meanwhile, are concerned that the system's efficiency could be affected, and some argue that only vertically integrated systems can guarantee a reliable electrical power supply.
U međuvremenu, eksperti izražavaju zabrinutost da bi to moglo da utiče na efikasnost sistema, a neki od njih ukazuju da samo vertikalno integrisani sistemi mogu da garantuju pouzdano snabdevanje električnom energijom.
