Lab 14 Electricity Bill Worksheet Background knowledge. The power of an electrical appliance is measured in watt (W). One watt is a measure of the energy used up in one second. The unit used for calculating power consumption is the kilowatt-hour (kWh). In order to calculate power consumed by an electrical appliance, we first convert the power to kilowatt (kW). For example, 800 W=0.8 kW, 2000 W = 2.0 kW and so on. One unit...

4. For an energy source with constant energy production and no operating cost, the levelized cost of energy (LCOE) per kilowatt hour (kWh) can be calculated as: annualized capital cost annual kWh production The annualized capital cost is like a mortgage payment, an annual cost that includes paying both the principle and interest (or opportunity cost of capital) over the life of a project. This can be calculated as: Annualized capital cost = K where K is the capital cost,...

An air-conditioner with air-cooled evaporator costs $50,000. With EER of 2.16 kcal/h W it is estimated to use 140 kWh of electricity daily on an average day requiring cooling. Similarly, a new type of air-conditioner employing evaporative cooling condenser costs $120,000. The EER of this air-conditioner is 4.66 kcal/h W and is estimated to use 75 kWh of electricity and 750 liters of water daily on an average day requiring cooling. The former air-conditioner would have a useful life of...

Great Eastern Inns has a total of 1,200 rooms in its chain of
motels located in eastern Canada. On average, 65% of the rooms are
occupied each day. The company’s operating costs are $20 per
occupied room per day at this occupancy level, assuming a 30-day
month. This $20 figure contains both variable and fixed cost
elements. During February, the occupancy rate dropped to only 45%.
A total of $399,600 in operating cost was incurred during
February.

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.
