Sorry but you've still got this all wrong. Again, number of transactions has no relation to the amount of energy used for mining. There is zero relationship there.
Let's say a block can accept exactly 1000 transactions. Imagine we have two forks Bitcoin1 and Bitcoin2 both of which are valued at $10 per coin and have the same supply.
Bitcoin1 has blocks with a single transaction along with a coinbase output.
Bitcoin2 has blocks with 1000 transactions all paying the minimum fee to cover their transaction size.
Which one do you think secures more energy per block?
