This is not correct actually. Simpler ISA often requires bigger instruction caches, but consumes less energy because of simpler decoding logic. VLIW theoretically can be super efficient, because it discards decoding stage altogether.

In theory, yes. This is the case when you have small cores, which is why a lot of GPUs used VLIW.
But in practice the whole decoder stage is basically a rounding error because cores got so big.
