Bitcoins would create environmental problems soon
Data consultant and blockchain specialist Alex De Vries believes that the amount of energy Bitcoin mining consumes is problematic. 
In a recent research study published in Joule, De Vries found that the average amount of electricity consumed per Bitcoin transaction is 300 kwH, and at the rate new miners are joining the network – and the mining difficulty increases – this number has the potential to reach 900 KwH by the end of 2018.
This is just one more thing added on to the list of why renewable energy is so important. We must fund, research, and discover improvements to our renewable energy production. That would help make this environmental issue go away. Excellent share!
