The miner hash power secures the blockchain and is independent of transaction rate. Increasing the transaction rate does not require any additional energy expenditure and transaction rate (block size) has already been increased twice since Bitcoin's inception. Dividing the total power consumption of bitcoin by the relatively small transaction rate makes for good headlines so I'd expect it to continue even though the two are unrelated.
