Transaction fees are not just proportional to usage. They are a price set by demand (usage) and supply (block space). Currently Bitcoin limiting the block size to 1MB is artificially lowering supply. Recently, Bitcoin Cash has surpassed Bitcoin in transactions per day: https://bitinfocharts.com/comparison/transactions-btc-bch.html#log&1y https://bitinfocharts.com/comparison/transactions-btc-bch.ht... Their blocks are larger, so there is more room for transactions, so miners are not so well rewarded, so they can afford to waste less electricity in total. Of course, this reduced waste implies reduced security (instead of securing >$700k/h, it's "only" $8.5k/h - https://www.crypto51.app/ https://www.crypto51.app/).
