35. A refrigerator consumes 294 kWh of electricity per year. Determine the primary energy requirements in units of MMBTU for the refrigerator assuming: a. The electricity came from a coal power plant with an efficiency of 32%. n = (e/e1) x 100 32 = (294/e1) x 100 e1 = 918.75 kWh per year e1 = 918.75 x 0.003412 MMBTU = 3.1349 MMBTU b. The electricity came from a natural gas plant with an efficiency of 44%. n2 = (e/e2) x 100 44 = 294/e2 x 100 e2 = 668.1818 kWh e2 = 668.1818 x 0.003412 MMBTU = 2.279 MMBTU 36. Determine the kilograms of carbon emitted per year in both scenarios of the previous problem. Coal: 0.027 gC/BTU, Natural Gas: 0.016 gC/BTU.
