The more these critics press the energy issue on bitcoin, the more people will ignore it. It is not the miner's fault that they are using energy that comes from fossil fuels, but rather the providers that supplied them with such. Some operators have already stepped up their game and used hydroelectric power on their operations, and these critics don't even care to include those on their reports. Nuclear energy is always available to be used, but the amount of building an infrastructure would cost much, that's why most energy companies tend not to do it. It's greener and cost-efficient in the long run, but then fossil fuels and coal are still being used for most of the world's power.

The blame has to be thrown somewhere, and bitcoin is the perfect candidate for that.
