Today I read this article.....

https://www.ccn.com/bitcoins-electricity-usage-could-power-all-of-austria-in-the-future/

It says in 2018 Bitcoin mining may consume 0.5% of worlds electricity in 2018.
I think this is because the mechanism "PoW" of Bitcoin. It costs a lot of power. And it looks like this statistics only includes Bitcoin, but there are still other coins can be mined.
I am sure for some people this is not environment-friendly and this could be used as the reason to restrict Bitcoin.

Will this affect the future of Bitcoin? or will there be any new energy-saving mining method for Bitcoin or other coins? How do you think about this?

Nowadays less energy spent on bitcoin mining..
But not because new-invented technology, it's because people are leaving bitcoin mining due to no more profitable..
Sad truth..

People leave bitcoin mining for good? No, it cannot happen long term. It is a self-regulating feedback loop. You see, when the profitability drops, people leave mining, hashrate drops, then as a consequence difficulty drops and profitability rises. What you may have been seeing are short term fluctuations. Even the halving didn't hurt profitability long term.
