Abstract

Since the rapid development of information age and information technology might be considered to cause environmental problems, Green IT is perceived as core technology for low carbon green growth and the minimum waste of electricity. In this vein, Green IT is becoming new paradigm of focusing on natural environment. This study examines current various IT required for green growth, and studies various methods for diminution of carbon discharge in Korea and other countries. Especially, it focuses on the diminution effect of carbon discharge by using Green PC, and compares the difference of voltage, voltaic current, and the use of electricity between Normal PC and Green PC by using HPM-300A, and measures carbon discharge of Normal PC and Green PC. The result shows that the diminution effect of $CO_2$ discharge of Green PC is amount to 11.5Kg per year, and the effect of green growth is up to the conservation of 2 or 3 pine trees.

정보화와 IT의 급속한 발전으로 iT가 환경 문제를 유발하는 요인으로 작용하고 있으나, 그린 iT기술이 저탄소 녹색성장을 실현할 수 있는 핵심 기술로 인식되어 전력소비를 최소화하는 연구가 진행되고 있다. 이러한 상황에서 그린 iT가 자연환경에 초점을 맞춘 새로운 패러다임이 되고 있다. 본 논문에서는 녹색성장을 이루기 위해 요구되는 다양한 iT 기술현황을 조사하여 국내외의 탄소 배출량 감소를 위한 다양한 방법을 연구하고 그린 PC를 이용한 탄소배출량 감축효과를 연구하기 위하여 일반 PC와 그린 PC의 전압, 전류, 전력사용량을 HPM-300A 측정기를 이용하여 일반 PC와 그린 PC의 전력사용량차를 측정하여 그린 PC가 배출하는 $CO_2$의 배출량과 일반 PC의 $CO_2$ 배출량의 차이를 계산하여 $CO_2$ 배출 감축효과를 측정하였고, 녹색성장효과를 측정하였다. 그 결과 그린 PC의 $CO_2$ 배출 감소효과는 1년에 11.5Kg의 감축효과를 가져올 수 있으며 녹색성장효과는 1년에 소나무를 2.3그루를 적게 심는 효과를 얻을 수 있다.
