Too much energy consumption makes PoW consensus non practical and not suitable for real world system. We need to find out other innovative consensus where transaction and network remains de-centralised but without much energy consumption.

We need to find out innovative solution to replace PoW Consensus with other Consensus which gives more efficiency, speed and less energy consumption.
