Comparative Analysis of Energy Consumption of Cryptocurrencies with Experimental Study Approach in the Scope of Green Computing
Öz
Many technologies enter our lives with the great advancement in information technology. These technological developments affect and change our life directly. According to affection of our life, cryptocurrency is the most popular technology. This technology, which is a relatively mixture of currency and cryptology, is used all over the world with increasing acceleration. So, cryptocurrency technology is still used to make payments without banks and is considered as virtual currency. Besides of this opportunity, cryptocurrency has few challenges. Most dangerous and critical challenge for environment is energy consumption in mining of cryptocurrency. Blockchain is the technology which is used in mining process and it consumes more and more energy. According to this critical challenge, Ethereum which is one of the popular cryptocurrencies, was used in an experimental study to analyze energy consumption. Experiment examined the data from Mar 30, 2017 to Dec 30, 2019. These data were compared with another popular cryptocurrency which is bitcoin in order to find the better one for environment. In this study, the data from 196 GPUs were examined and electricity consumption and gain were analyzed. Totally, 3 different types of GPU brands were used, and the brand of the units, the power consumed, and the electricity unit price in the country where it was tested were analyzed respectively.
