The whole "mining is a huge waste of electricity" motion is just completely wrong.
Mining currently uses between 105MW and 150MW.
However, the act of mining is the act of keeping the Bitcoin payment system alive and secure.
Do you know how much electricity all the banks in the world use for their "services" to the people?
Hint: It is most likely much more.
Nonsense, the comparison between mining and the banking network is specious.
You don't have to mine fiat the power consumption of the banking system is to provide the layer above the currency, the accounting, recording, lending and other services. Bitcoin still needs those infrastructures as well, it's just that it's not widely accepted so that part of the infrastructure is currently quite small, but growing every day. If Bitcoin becomes mainstream and adopted by banks and credit card providers, you wait and see how much total power is used then!
Mining uses a
miniscule amount of energy compared to all the wasteful use of electricity in the United States alone.
How come the electricity consumption per capita is more than 2.5* that of Germany?
If everyone of the 318m US citizens would reduce power consumption by only 10% (easily achieved by switching lightbulbs...), it would save
25 700 MW of generation capacity alone.
You can do all the bitcoin mining of your hearts´content with that, and then some.
