OP is idiotic.
The current financial system uses around 10,000 times more energy then bitcoin.
Think about how much oil you burn when you have brinks trucks driving around to fill up ATMs and move cash around.
Switching to Bitcoin would save the environment.
and Bitcoin uses around 3,000 times more energy then Nxt. That is what OP wanted to say
And Solarcoin is more efficient than Nxt.
Bitcoin wastes electricity in it's process while Solarcoin generates electricity in it's process. Asics are also terrible because it results in centralization which makes mining a losing activity for most of the people doing it.
Compare it to Bitcoin or Nxt
