Today i saw a paper reporting that Bitcoin will eat all the electricity of the world , when it will be upgraded to mass level.  Although i think  Bitcoin may not be a total environmental disaster, the Earth would certainly be a greener place if the Bitcoin network didn't consume so much electricity to process a relatively small number of transactions. I think there are still something to develop.

There are few ways we can try :

• Right now there are basically three ways this could happen. One way, i got in this forum, is for Bitcoin's price to decline. Because the way of mining Bitcoin needs huge power costing , may be that is one of the reason of price hike. I actually wants Bitcoin as a stable currency rather than gambling.
• Another option would be to reduce the network's 12. 5 bitcoin-per-block reward sooner than the scheduled 2020 reduction. But that's easier said than done. Bitcoin mining companies are not going to go along with this willingly, and Bitcoin fans are likely to oppose such a move as well.
• A third choice is change the Bitcoin mining process fully. Bitcoin's present mining calculation depends on figuring a super massive number of cryptographic hash capacities. However, different digital forms of money have been investigating options and other ways. Bitcoin Gold is an as of late made variation of Bitcoin that uses a "memory-hard" mining calculation that may turn out to be less power hungry—however it would even now devour tremendous measures of juice. More fascinating mining calculations exist that could drastically decrease control utilization.

Government are helpless
Government authorities can also be are often powerless here. When any country tries to force a change, mining operations would simply flee to another jurisdiction. Changing Bitcoin by regulatory fiat would require a coordinated global regulatory effort, which does not seem to be  happen any time soon.

Changing to an elective mining calculation would likewise be questionable among traditionalists and would be unequivocally contradicted by mine workers. It would wipe out mining organizations' multi-million dollar interests in custom mining equipment. Such a stage isn't outlandish, yet it appears to be probably not going to happen at any point in the near future.
