Explanation:
A research into the energy usage of Data centers was released in 2020 and showed that even though there has been a 550% growth in the demand for data centers, the energy needed to power them has only grown by 6%.
According to the scientists who conducted the research, the reason for this is that the data centers have a relatively high efficiency rate when it comes to energy usage such that data centers use only around 1% of the world's electricity.
