Typical replacement for a 100 W incandescent bulb is a 20 W LED bulb. The 20 W LED bulb provides a comparable light output to the 100 W incandescent light bulb. Assuming the average energy rate charged by the power company is RM0.10/ kWh and the bulb is turned ON for three hours a day, determine the cost savings for using the LED bulb instead of the incandescent bulb for one year.

Suppose the cost of an incandescent bulb is 28 cents and that electricity costs 10.5 cents/kWh. Compact fluorescent lightbulbs (CFL), while they are more expensive, use 1/10 of the power for the same amount of illumination. What would be the maximum cost (in dollars) of a CFL such that the total cost (investment plus operating) would be the same for both CFL and incandescent 60 W bulbs? Assume both lightbulbs run for 1000 h.
1.) An incandescent lamp, rated at 100 watts, gives a certain amount of light when placed across the 120V ac power line. Would the amount of light increase, decrease or remain the same, when the lamp is placed across a 120V dc power line? Discuss. 2.) Explain what is meant by effective current and effective voltage.
A small plant has been constructed and the costs are known. A new plant is to be estimated with the use of the exponential (power sizing) costing model. Major equipment, costs, and factors are as shown in the shown table. (Note MW = 106 Watts.) If ancillary equipment will cost an additional $200,000, find the cost for the proposed plant.
a compact fluorescent lamp uses less energy than its equivalent incandescent bulb.how much will a person save if he/she uses a 20 cfl instead of a 100 w incandescent lamp for 6 h in 30 days? electricity is priced at p 8.17/kwh
A no. 000 AWG wire is 100 meters long. For no. 000 wire, it has a wire resistance of 0.0618 ohms per 1000ft. Determine the power loss if the current flowing through the wire is 18 amperes.How much must you pay for the loss in the previous problem due to the voltage drop if during the whole month, you used the wire for 300 cumulative hours? Assume a rate of 5 pesos per kWh. Can you solve for it? If yes, solve the value in php. If not, type (unsolvable).
Question 5 A natural gas plant with a 50MW operates at an average loading of 75% year round. How many kWh does the plant to supply to the grid? Question 6 For Question 5, the natural gas power plant costs $175,000,000 to build and costs $20M a year to operate. What is the average cost per kWh or MWh for the power produced if the estimated plant life is 20 years? Assume a discount rate of 5%.
A 65000-kW thermal power station uses coal of calorific value 15000 kcal per kg. if the coal consumption per kWh is 0.5 kg and the load factor of the station is 40%, calculate (i) the overall efficiency (ii) coal consumption per day.
What is the thermal efficiency of a coal fired thermal plant having a coal consumption of 0.48 kg/kWh and the calorific value of coal used is 6200 kcal/kg?
A 100 W CFL light manufactured by Buyer’s Choice consumes 23 watts andhas an illumination rating of 1600 lumens and service life of 8000 hours andcosts $1.81. As an alternative, a generic 100 W incandescent light bulb costs$0.38 and produces 1500 lumens and has a service life of 750 hours. Let uscompare the performance of each light bulb by calculating the efficacy foreach light, and also estimating how much it would cost to run each light for 8hours per day for 220 days in a year. We will assume electricity costs 9 centsper kWh.For the Buyer’s Choice 100 W CFL light:
Compute for the time it takes for an electric stove to consume 60 kJ for a 220-V line drawing 30 A of current.
Assuming that the Philippines is consuming 3.5×10^20 kWh of electrical energy in one year and the power plant has a conversion efficiency of 32%. Determine the mass of fuel consumed in kg for one day operation if the fuel used is anthracite coal with heating value of 30080 kJ/kg. Express the answer in 4 significant figures.
Should You Buy an Electric Car? Do the math. This article says that the EPA rating for the Nissan LEAF is exactly 30 kWh per 100 miles Assume you drive 15,000 miles per year Assume you pay 7.8 cents per kWh (kilowatt-hour) Assume your current vehicle gets 32 miles per gallon and gas cost $2.50 per gallon Which is cheaper to drive, your current vehicle or the Leaf?* What else should you consider before purchasing an electric vehicle? Ready to decide? Make an argument for either keeping your current vehicle or for getting an electric vehicle. Don't have a car? Make an argument for using public transportation and ride-sharing services.
