Kind of a self-defeating list. As a PoW cryptocurrency becomes more popular, the value of a single coin goes up, so the mining reward will go up in terms of USD. As a result, the equilibrium energy usage in mining goes up proportionally to the increase in value. So if people start using a cryptocurrency because it is more efficient, it will stop being efficient.
