Energy used by BTC

[simbax]

Good afternoon
In my country the main news channels are not for BTC, but they have to talk about it

The biggest point agains BTC is that every transaction uses a huge amount of energy.
Some main newspaper said that one trasaction uses the same amount of enegery neede to warm up a flat for a week.

To me it doesn't make much sense

Are the some real data about power use?
How can we know how much pover BTC uses?

Yes, there are power uses when earning bitcoins, especially if you're one of those miners. Mining requires high powered computers in the first place.
