5 | Page - MATH 123-ONLINE-2023 Spring NAME: 6 | Page --MATH 123-ONLINE.2023 Spring NAME: For Solar power produced in 2020 we take the 97,835 Megawatts of installed capacity (taken from the above table]. In 2020, electricity accounted for 19.97 quads, or about 21.5% of all energy used. In 2050 electricity will grow to about multiply it by 9.8 hours a day of sun and then multiply that by 365 days in a year. This gives us 349,955,795 megawatt 31.2 quads, as electric demand is expected to increase by 1.5%% per year (estimates vary and are highly impactful). hours of power in a year. From the above conversion: According to the US Energy Information Administration (EIA) the total energy demand in the United States will increase to 349,955, 795 megawatt hours . 343,071043 megawatt hours = 1. 19 quads 108.66 quads by 2050. In 2050, electricity will make up 31.2 quads or 28.7%% of the total energy usage. This should closely match your answer to 6a. This is a massive transformational shift from petroleum-based energy to non-petroleum based electricity that will be occurring in your lifetime. In order to dramatically reduce greenhouse gases, mainly Carbon Dioxide, electric power For Wind power produced in 2020 we take the 590,915 Megawatts of installed capacity, multiple it by 3.91 hours a day of generation will need to be derived from sources that do not emit greenhouse gases. These include wind, solar, nuclear, suitable wind and then multiple that by 365 days in a year. This gives us 843,324,342 megawatt hours of power in a year. hydroelectric, geothermal, etc. From the above conversion: 843, 324, 342 megawatt hours * 1 quad 295,071083 megawatt hours = 2. 88 quads 1 quad = 293,071,083 megawatt hours This should closely match your answer to question 6c. Important: A megawatt is a unit for measuring power that is equivalent to one million watts. One megawatt is equivalent to the energy produced by 10 automobile engines. Finally, you are now going to use linear models to project how much Solar and Wind might contribute to the United States energy picture in the year 2050. A megawatt hour (Mwh] is equal to 1,000 Kilowatt hours (Kwh). It is equal to 1,000 kilowatts of electricity used You must watch this short video first: https://youtu.be/ErekIDMUL_G continuously for one hour. It is about equivalent to the amount of electricity used by about 330 homes during one hour. Short video on energy (watts or kilowatts) vs power (watt hours or kilowatt hours): The data from the above graphs are in the accompanying Excel file. The tab is called Solar and Wind Tables. https://www.youtube.com/watch?v=|Be3FGpix3Y 7a.) From the data and the linear equation in the Excel file determine the projected installed megawatt (MW) capacity for The following two graphs detail the cumulative amount of installed Solar and Wind. They only generate power when the Solar in 2050 assuming the rate of change remains the same. sun is shining or when the wind is blowing. Most large-scale Solar installations are placed in very sunny areas. Most large-scale Wind installations are placed in very windy areas. The number of hours of sunlight and suitable winds are an average across the county, used here only for demonstration purposes. 7b.] Using the calculations shown above determine how many quads are projected to be produced by Solar based on your answer in 7a.

Cumulative Installed Wind Power Cap By Year, 2000-20, Choose any ONE (1) of the topics. MW 700.000 Extra Credit is worth up to 5 points. 600,000 Is Climate Changed a settled fact? 500,000 it is a fact that humans exert an influence on the environment. Many people think Climate Change is an existential threat. 500-915 and argue the science on the topic is settled. Steven E. Koonin, a lead scientist in the Obama administration recently 523,771 460,000 471,144 published a book called Unsettled. In this interview he examines the current science around Climate Change. 423 219 300.000 Watch the interview: http:://www.youtube.com/watch?v=-OFLIQyWilM 340.544 In a paragraph or so summarize the arguments made and then state what you learned or state your opinion with some 306 897 200.000 141 AM reasonable justification. 271.908 121 013 94.113 234, 120 74,130 59,091 100.000 10431 47,620 199 807 23 900
