2 Question! Byte = 8 bits ASCII Code American Standard Code for Information Interchange

3 Apple II -> Year 1977 My First personal Computer, year 1985!!! 1 Byte = 8 bits X 2 ^ Byte = 1KB 48KB Question! How many times bigger? USD 1 = KRW 1150 USD 214= KRW 247,000

4 Electric Power & Tariff How much of electric power to be consumed if this computer is ‘power on’ for one whole month? 500W x 24Hour x 30Days = 360,000Wh = 360kWh

5 Korea Nuclear Power Plants (Kori) One Nuclear Power Plant Capacity 1GW = 1,000MW = 1,000,000kW

6 Photovoltaic 6 East Sun Power Gen. Co. - 24MW, 0.7Mil m 2, US 200Mil. 1 Nuclear Power Plant => 1GW = 1000MW 24MW x 40 approx. 1000MW Capacity : to be equivalent to 1 Nuclear Power Plant (x 40 times) -> 28 Mil m 2, US 8,000 Mil. (US 8 Bil.) Power Generation: to be equivalent to 1 Nuclear Power Plant (x 5 times) (with capacity factor of 20%, tracking device) -> 140 Mil. m 2, US 40 Bil. ** Still we don’t get power during the night, rainy days,…

23 Introduction GCAM is a global integrated assessment model of interactions among the global economic, energy, agricultural and land use, climate, and technology systems. IA models are not predictive - but should be used as research and analysis tools to aid understanding of the complexities and interactions. GCAM was one of four models chosen to create the representative concentration pathways for the IPCC’s AR5 South Korea is already a separate region Long-term model (runs through 2095) Dynamic and recursive model Technologically detailed 23

24 GCAM(PNNL) 에너지 시스템, 농업&토지이용, 기후, 경제 부문이 연결되어 있음 에너지와 농업&토지이용의 공급측면에 있어 여러 기술의 적용이 가능 전력 부문에 있어 화석연료 이외에 원자력, 수력, 태양에너지, 풍력, 지 열을 포함하고 각각의 원별 시장에서 건물, 산업, 수송 부문으로의 투입 구조 Energy Demand is determined by the GDP and the energy demand technologies Energy Supply is determined by the Resource Bases and Energy Conversion Technologies The flow of energy from supply side (primary and secondary fuels) and end- use sectors (buildings, industrial, transportation) 24 자료 : Calvin K., 2010
