Adding more interesting recent information to this topic because I think bad news propaganda against Bitcoin is going to get worse in near future, so we need to have more debunking information about this topic.

Nic Carter wrote and posted interesting new article for HBR Harvard Business Review explaining how much energy Bitcoin actually consumes.
We hear people talk a lot about Carbon Emissions (btw we are all made of Carbon so think about that) for Bitcoin and confusing it with energy consumption, but various research are showing that between 39% to 72% of all energy used for mining Bitcoin is actually hydro energy.
Interesting thing is that Bitcoin mining consumes energy that can be spent anywhere in the world and Bitcoin doesn't have that limitation like all other applications that need to be near energy sources.

In other article written by Hass McCook we can see great comparison made for energy consumption for Bitcoin, Gold, paper currencies and banks.
We can see that much more energy is spent and much more CO2 is produced with combined gold mining, making of gold jewellery and gold recycling  than for Bitcoin mining.
If we look at all Banking system and ATMS than we can see multiple times higher numbers according to McCook research with 400 milllion CO2 produced and 700 TWh energy used.
Maybe we still do need to use current banking system everyday but imagine how much energy would be saved if we didn't have ATMS anymore and if we stop making more gold jewellery.
