Considering the fact you can mine bitcoins via special cloud mining services, I wouldn't say that it always consumes as much energy as mentioned above. For example, I have a friend who tries to make a living off crypto and to maximize his income he uses hashflare codes such as these http://hashflare-redeem-code.n... for his contract and it works quite well for him. Basically he kills 2 birds with one stone, no extra costs for electricity and consistent profit from his contract.
