Unless you need to edit, it's safer to stay in Protected View Enable Editing Imagine a country geographically located Mediterranean region and has the following values by the year 2020. 1. Population 80 million, GDP = 750 billion USD, Total Primary Energy Supply (TPES)=120 Mtoe/year, Energy Produced inside the country = 20 Mtoe/year, Total Energy Export=0.5 billion USD. The shares of the imported prime energies are Coal 25%, Natural Gas 40% and Petrol 35% a) Calculate the cost of net energy import b) The ratio of energy exports/energy imports c) Obtain Energy Intensity d) Obtain TPES per capita 2. You are planning an Electrical Energy Policy for this country for 2022. In 2021 electric power stations are constructed, thus no additional energy is produced by them. Electricity Consumed in year 2020 = 350 TWh/year. Increase rates per year :Population = 1.5%, GDP = 5%, Electricity = 6 %, The Increase of Power Mix would be planned for 2021 as follows: Natural Gas Power Stations............... 20% of the increase of energy for 2021 Coal Power Stations ............................ 10% On Shore Wind Power Stations....... 25% Off Shore Wind Power Stations......... 15% Photovoltaic Solar Power Stations..... 20% River Hydraulic Power Stations......... 10% a) Calculate the Power of each electric power stations defined above b) Calculate the cost of each electric power stations construction cost + running cost +operation & maintenance cost) c) Add the financial cost considering 10 % loan interest and obtain Total Cost d) What is the ratio of Total Cost / GDP e) If the price of electricity to be sold at 10 cent/kwh, how many years required to compensate the cost? f) Calculate the consumed electricity per capita in 2022 For solar radiation, assume Mediterranean level. For onshore wind assume only 90 days per year the rated power is possible. For offshore wind assume 180 days per year the rated power is possible

Answer 1

u pego solution ③ Giren population = Bomillion. GDP = 150 billion Totul primary energy supply (TRES) = no Mitbe (year. Energy produce inside country = 20 Mkoe fyear Totul energy Export = .0.5 billion Usi). or cost of Export = 0.5 billion USD. We know that. in USD - Rea 19 X Cost of Export = Rate of Energy & Energy Produce . 8.5 billion USD = Rate of energy x 20 Merel year Rate of energy = 0.5/10 E 0.015 billion Usi) Energy cost of het Energy Import = Date of energy & Energy import Energ Import = Tres – Energy produce - = 100 I + - 120 - 20 = 100 ort= 0.025 xloo last of het energy Inpost a billion viD. Ratio of energy export (Energy import - Energy roduce P 20 -0.2. Too loo
