We can estimate the energy consumption, based on the complexity of bitcoin. Complexity is the value calculated by the protocol and attached to each block. Complexity measures the average number of hashes left by the miner to search for one real block.
I think that to calculate how much the entire network uses bitcoin and compare with the amount of energy that a particular country uses can only be done with special skills in the field of electricity
Even though how skilled the person is,still no one can calculate the usages of bitcoins electricity the whole world.and besides i believe that what you have said in the OP above wasnt the right volume of whats the true electricity needed,you should have drop some links on where did you get that idea
Bitcoin needs a lot of power so you can maintain it, it's pretty high
What maintaining youre talking about?you noob speaks when you really have idea abiut the topic but if not stop talking as if there's an understanding about issue
