Problem 2 If the cost of electricity in your area is 12 cents per kWh, what is the total cost (capital plus operation) of using a 60-W incandescent bulb for 1000 hours (the lifetime of that bulb) if the bulb cost 25 cents? If we replace this bulb with a compact fluorescent light that provides the same light output, but at one- quarter the wattage, and which costs $1.50 but lasts 10 times longer (10,000 hours), what will that total...

Problem 8.14 A house is heated with electricity at a cost of $0.10 per kWh. The building has 20 m² of double-glazed windows with an Rsı value of 0.4. A mechanism is constructed that covers the windows with 10 cm of polystyrene foam at night (i.e., for 12 hours per day) during six months of the year. If the outside temperature is constant at 0°C and the inside temperature is kept at 20°C, calculate the annual savings from this approach.

US government website says the following interesting information: In 2017, the average annual electricity consumption for a U.S. residential utility customer was 10,399 kilowatthours (kWh), an average of 867 kWh per month. Louisiana had the highest annual electricity consumption at 14,242 kWh per residential customer, and Hawaii had the lowest at 6,074 kWh per residential customer. Let us compute the electricity usage and the bill for last month by asking a few questions to a homeowner. Here are the input...

The lighting needs of a classroom are met by 30 fluorescent lamps, each consuming 80 W of electricity (Fig. 2-52). The lights in the classroom are kept on for 12 hours a day and 250 days a year. For a unit electricity cost of 11 cents per kWh, determine annual energy cost of lighting for this class- room. Also, discuss the effect of lighting on the heating and air-conditioning requirements of the room.
