Some cryptocurrencies use lots of energy as they are proof of work. It's undoubtedly a weak point and something that can be improved on but it's also often used as something to target by naysayers. Paper currencies may use a lot less energy in terms of production but in others ways they are a lot less environmentally friendly, these calculations exclude many things which are incalculable
