Nowadays, cryptocurrencies use the same electrical power as Argentina but sooner the technology will operate by means of renewable sources of energy as the analytics confirm. Bitcoin has run the 9-th place at total market value in the world that is demonstrated at BitMix The explosive growth of cryptos has made millionaires and started an industry of billion dollars. However, it has also downsides to cryptocurrencies. 

The energy issue

The computation power is so enormous that draws criticism about the environmental impact. The Cambridge University has researched that the bitcoin net requires approximately 120 terawatt-hours a year. This suggests that if it were a country it would come into 30-ty major electricity users in the world. The demand for electricity has been caused by the bitcoin price increase as a result it has advanced from 5.000 dollars to 50.000 dollars. Charles Hoskinson is an executive general manager of a company IOHK claims that energy usage has increased fourfold from the 2017 year and it will go downhill through the years. 

The carbon foot print of Bitcoin will increasingly worsen because of the big price. Therefore, there is high competition for the currency and major consumption of energy. Besides, most miners are located in the People’s Republic of China where electrical power works out coal that is rated two-thirds of the total electricity. 

That is why, the miners are searching the locations where electrical power is the cheapest, incidentally the significant issue is in default of producing inexpensive renewable energy. The miners are making use of inexpensive geothermic and hydroelectric energy for the power supply of machines in Norway and Iceland. Moreover, intense cold cuts down expenses by the effect of free-cooling of computer host. The research of the Cambridge University has demonstrated that 75% of cryptos miners take advantage of renewable sources in the activity.
