Consider a light fixture A "efficacy=40" to be replaced by light fixture B "efficacy-88" where there are 20 fixtures are used in a 16 m x 18 m x 3 m room with resulting illuminance of 454 Lu/m for both types, lights are used for 5400 hours per year and the grid efficiency is 35%. What is the annual amount of fuel reduction "Liters", if the power plant uses fuel with heating value = 25.56 MJ/Liters?

Problem 18 %. The overall efficiency of an electric system, coal pile to lights a lamp is What fraction of a kg of coal containing 10250 KJ/kg must be consumed to light a 1350 W lamp for 45 minutes? Ans. 1.976 KJ
C. Suppose that a certain fraction of the power produced by a 350 MW coal plant is offset by wind power. Assume that when the coal plant runs at its constant rated power it has an efficiency of 37%, but that when it needs to be ramped up and down to compensate for the wind power variations its efficiency is reduced by according to e=0.37-0.00001p², where p is the amount of wind power. Find the percentage increase in emissions that results when 90 MW of the 500 MW is generated by wind power instead of coal. What will be the maximum power of the plant?
