Project: Energy Yearly Projections Using Electricity, Coal, and Oil Assignment Instructions

Overview

Ever wonder how your electricity bill is computed? The following tables gives the watts of power that are typically required by several major (and not so major) appliances and an approximate number of hours each day the appliance is used. This project will focus on various calculations of energy and cost of commonly used appliances using electricity, coal, and oil.

Note: The source of the data located on the below table has been rounded. A direct link to the original data is located under the Project: Energy Yearly Projections Using Electricity, Coal, and Oil Resources section entitled How Much Power Do Your Appliances Use?

Instructions

Using the information in tables 1 & 2 and the Project: Energy Yearly Projections Using Electricity, Coal, and Oil Data Setspreadsheet answer questions 1 - 7. You will submit the finished spreadsheet as the project in Canvas.

You can locate the Project: Energy Yearly Projections Using Electricity, Coal, and Oil Data Set spreadsheet under the Project: Energy Yearly Projections Using Electricity, Coal, and Oil Resources section.

Table 1:

Appliance	Central Air Conditioner	Water Heater	Clothes Dryer	Oven	Dishwasher	Fridge	Ceiling Fan	LCD TV
Watts	3800	4500	3000	1200	1500	1400	120	150

Assume that the number of hours that the aforementioned appliances run during an average day is given in the table below:

Table 2:

Appliance	Central Air Conditioner	Water Heater	Clothes Dryer	Oven	Dishwasher	Fridge	Ceiling Fan	LCD TV
Hours	8	3	2.5	2	1.5	24	6	6

Add columns to the Project Data spreadsheet that show the following for each appliance (where applicable round to at least two decimal places):

1. The number of kilowatts of power required by each of these appliances (1 kilowatt = 1000 watts).
2. If the appliance runs the number of hours specified in Table 2, compute the kilowatt-hours (kWh) of energy that each appliance consumes during an average day. Note: kWh are found by multiplying the power of an appliance by the number of hours that it is in use.
3. The number of kilowatt-hours used by each appliance in the entire YEAR.
4. Assuming that electricity costs $0.14 per kWh, find the electricity cost of running each appliance for the entire year.
5. According to the US Energy Information Administration, it requires 0.00057 tons of coal to generate 1 kWh of electricity. Use this conversion to find how much coal would be required to run each of these appliances for a year.
   1. Note: A direct link to this data is located under the Project: Energy Yearly Projections Using Electricity, Coal, and Oil Resources section entitled How Much Coal, Natural Gas, or Petroleum is Used to Generate a Kilowatt-Hour of Electricity?
6. The same source also states that 0.00173 barrels of oil will generate 1 kWh of electricity. Like question 5, find how much oil each appliance would consume on an annual basis.
7. Add a "Total" row to the spreadsheet that shows how much electricity is consumed by all 8 appliances combined in the course of a day and of a year. Also, find the cost, the amount of coal that would be required, and the barrels of oil that would be required in order to run all 8 appliances for a year.
