Calculating a Personal Energy Budget

Introduction:

The Energy Information Administration (EIA), a branch of the U.S. Department of Energy, regularly conducts a Residential Energy Consumption Survey to provide information about household energy use in the U.S.  For the most recent survey (2015), data were collected from 5,686 households statistically selected to represent the 118.2 million housing units that are occupied as a primary residence. The survey consisted of household interviews, as well as actual energy consumption obtained from household billing records maintained by the energy suppliers. Statistics on energy use cited throughout this lab were obtained from survey results from the most recent Residential Energy Consumption Survey.

According to the latest survey results, average U.S. energy consumption in homes has decreased by approximately 25% over the past over the past 20 years, with the average household consuming 77 million British thermal units (Btu) per year. This decrease is mainly due to improvements in energy efficiency for lighting, space heating, air conditioning, and major appliances. Newer homes also tend to feature better insulation and other characteristics, such as double-pane windows, that improve energy efficiency and prevent waste.

This lab consists of a survey of energy use in your household.  Daily energy use will be calculated for the following categories: electricity and transportation.  In addition, you will calculate potential energy savings associated with energy-efficient technologies. Please type all your numbers and answers in RED, so they can easily be found.

  1. Electricity Consumption
  2. Home Light Usage

Artificial lighting consumes approximately 10 -15% of a household’s electricity use (www.eia.gov). The Energy Independence and Security Act of 2007 established new efficiency standards, requiring lightbulbs to use about 25% less energy than traditional incandescents. Energy-efficient lightbulbs typically use about 25%-80% less energy than traditional incandescents, and include halogen incandescents, Compact Fluorescents (CFLs), and Light-emitting diodes (LEDs). The new bulbs provide a wide range of choices in color and brightness, and many of them last much longer than traditional lightbulbs (www.energy.gov). Replacing incandescent lightbulbs with energy efficient bulbs can save a typical household more than $50/year (www.energy.gov).

 

On an average day at home, record in Table 1 the time in usage and wattage of all lights turned on in the house.  If you are using incandescents, the wattage ranges from 40-150 watts and is usually printed on the bulb. For compact fluorescents or LED bulbs, the approximate wattage equivalents are given in this chart:

 

LED Wattage                            CFL Wattage             Incandescent Wattage

6 – 7W 8 – 12W 40W
7 – 10W 13 – 18W 60W
12 – 13W 18 – 22W 75W
14 – 20W 23 – 30W 100W
25 – 28W 30 – 55W 150W

Calculate kilowatts used in each room and for the whole house using the following formula:

 

 

Wattage x hours per day  = KWh used

1000

 

 

For example, if you have two 40 watt lights in the living room that are on for an hour and 45 minutes:

 

 

1.75hrs x 2bulbs x 40watts = 0.14 KWh used in living room

1000

 

Table 1. Data collected on light usage.

 0.14KWh
         
         
         
         
         
         
         
         
         
         
Total Lighting  
  1. Describe two changes in your lighting usage that would result in the greatest energy savings.

 2.How much energy would you save by switching to LED bulbs throughout your house? (from the table, LED bulbs consume energy at about 1/6 (0.17) the rate of incandescents. So, to calculate energy saved by switching from incandescent LED, first multiply total energy used by incandescents X 0.17. That’s the energy consumption with LED bulbs. Subtract that number from the total to find energy savings.

                           

                                 ____________KWh   saved

 

 

  1. Electrical Appliances

Heating and cooling homes consumes the greatest amount of energy, and accounts for almost half of total energy use in U.S. homes (www.eia.gov).  Appliances account for the second-largest use of energy and consume 35% of the total energy used in U.S. homes.  To calculate annual energy consumption from appliances, you must do the following:

 

  1. Estimate number of hours per day an appliance runs. For most appliances, you can do this by

recording how much time per day an appliance is used (record in Table 2). For those appliances that

cycle on and off, like a refrigerator, divide the total time the appliance is plugged in by 3.

 

  1. Find the wattage of the appliance. There are three ways to do this:

– it may be stamped on the appliance (look on bottom or back if possible).

– if amps are provided, multiply that by 120volts to get wattage.

– use an online table to estimate wattage of common appliances, such as

http://www.energy.gov/energysaver/articles/estimating-appliance-and-home-electronic-energy-use

Scroll down the page to find a link to Home Energy Saver which lists wattages.

  1. Describe three changes in appliance use or heating/cooling that would result in the greatest energy savings in your household.

4How many KWh would these changes save? ______________KWh (You may estimate here. For example, you may decide to lower the thermostat, and you may estimate that this would save 20% of your heat pump cost. You can then subtract this from the total. Or, you may decide to ditch the hot tub, if you have one. You can then subtract this from the total.)

 

III.  Transportation

An average U.S. household travels 20,000 miles per year, and consumes over 1,000 gallons of gasoline per year (U.S. EIA, 2009). With gasoline prices at $2.50 per gallon, that equates to $2,500 spent per year on  gasoline.

 

  1. a. Estimate the miles you travel by car in a typical day. ____________ miles/day

 

  1. Calculate yearly mileage (answer in 5a x 365days/year) =  _________________ miles/year

 

  1. How many miles/gallon (mpg) does your car get? _______________ miles/gallon

  1. 5e – 6a = ____________ gallons/year saved

 

 

  1. Gas hybrid cars can average 50 mpg. How many gallons of gas would you save per year if you drove such a gas hybrid car?

 

  1. Gas used with hybrid:    5b    = __________gallons/yr used with hybrid

50mpg

 

  1. 5e – 7a = ______________gallons/yr saved with hybrid
  2. Assume gas is $2.50/gallon. What is the cost difference in gas among the three vehicles?

 

Your Car             Car getting 10 mpg more          Gas Hybrid

 

Total gallons consumed per year:    ________________      _________________       _______________

 

Total cost per year:                             ________________      _________________       _______________

(gallons consumed X $2.50)

 

 

  1. Refer back to your estimation of daily mileage (5d), and convert this number to BTU’s using the following equation:

 

gallons/day  x 114,100 BTU/gallon  = __________BTU’s/day

 

 

  1. Convert this to kilowatts and add to your daily grand total in Part IV.

 

BTU’s  =  ___________KWh/day

3412

 

 

  1. Total Personal Energy Consumption

  1. How much are you spending on energy use per year? In Maryland, the average cost per kilowatt/hr. is approximately $0.115. (https://www.eia.gov/electricity/state/maryland/)

 

 

KWh per day X $.115 =  $_________  per day  X  365 = $____________ per year
