Bitcoin  is  a  form  of  crypto currency.Crypto currencies  are a  kind of  currency  just  like other  that  serves  as  a  means   to  facilitate  trading.However,it  is  special  in  that,it  is  not  by  any  centralized bank or  government. Bitcoin  has  radically changed the  payment   model for  worldwide transactions.So  far  in  2018,the  number of  transactions has  ranged between the  150,000  and  400,000  per day  level,but now,as  more and  more people worldwide  start   using  Satoshi Nakamoto's  controversial creation,serious questions are  being raised about the  bitcoin  environmental  impact.Mining today reqiures  specialized application  specific integrated circuit [ASIC]hardware to  handle  the   computationally  intensive  processing  needed  to''solve  blocks''  or  verify  transactions  and  add them  to  the  blockchain. These machines run  hot  and  use  a  significant amount of  electricity to  perform  the  complex  calculations  involved in  mining.As a result,the  Bitcoin network uses an  increasingly  substantial   amount  of  electricity to maintain the  blockchain by  some  estimates around 32TWh per  year.There  is  no  question that  the  Bitcoin  Network is  indeed using a  huge  amount of  electricity.The  environment impact of this  however has  much  less  to  do  with the  amount  of  electricity being used than  it  does  with how  that  electricity is  being generated.While  it is  difficult  to  get  specific  numbers,it  is  widely  known  that  a  significant   majority  of  the  world's Bitcoin  mining  happens in  China,where  electricity  is  cheap  and  comes  primarily  from  burning  coal,and it b is  due  to  the high  demand of  electricity that Bitcoin  mining  demands,individuals  who  want  to  start bitcoin farms do  this  in  regions  where energy is  cheap like in  China  and  Russia,the  energy  productions  in  these regions  is  not  clean  as  they  are  primarily  created through the  burning of  coal  and  other  fossils fuels,which  is  what makes the  energy  cheap.However  with the  likelihood of  cracking  down  on  the  access  to  cheap  non-renewable energy,it  is  easy  to  imagine that mining  will  do  just  as  many  other technologies have  done  and  evolve to  changing  standards,adopting   more sustainable methods and  more  efficient  machines,as long  as  there are  still  profits  to  be  made.There already  are  innovative approaches to  using renewable  energy such  as  solar,wind and  hydro-electric  power to  operate mining  equiptment .Scientist worldwide  have been  sounding  the  alarm for  years in  relation  to  humanity Carbon  Footprint.The environmental  impact of  technology as  a whole is  something  that  the  international community will  almost  certainly be  struggling with  for many  decades to  come.While  it  is  important to  acknowledge Bitcoins role  in  contributing  to  the  much  larger  issue of  energy  consumption,society  should also  recognize that  the unpresidented rise in  Bitcoins popularity over the past  years has  forced this  issue  to  fore front  only  very  recently. So far,it  appears that  the  growing  global interest in  mining may  create a new  avenue to  innovation for  renewable energy as  manufacturers compete to  develop  and  optimize efficient mining equiptment. The world  is  already  seeing action  from  governments,Entrepreneurs,Environmentalists and  members of  the  Bitcoin community  to  develop more  sustainable solutions.Ref themarketmogul.com
