Appliance Energy UseMost consumers do not look at their energy use data from month to month, however most utilities provide some information on the monthly bills that consumers would find useful. It only takes a minute to review your usage to see if there is something unusual going on.

The picture on the left shows the annual usage data for our own electrical energy usage data for the past year. It shows the usage for the past six months and the same month from the previous year. The number of days for each measurement are shown along with the kilowatts used in that period. Our utility also offers time of use metering, with peak times, mid peak and off peak usage measurements.  There is also a total number of kilowats used for the period.

Our time of use metering stopped working for some reason in May and although we have reported this to the utility, they have yet to send someone out to fix it. The rates for each period are quite different with the peak rates almost double of that for the off peak periods. The utility implemented this approach to encourage consumers to use energy during off peak periods in an effort to reduce their peak usage during times of high use. Drying clothes, running the oven and turning up the air conditioning during the peak periods can reduce the overall amount of energy that is used and reduce the energy bill received each month.

Energy Use Data – Energy Periods

On Peak – energy use is measured from 11 am until 5 pm on weekdays excluding holidays

Mid Peak – energy use is measured from 7 am until 11am and from 5pm until 7pm on weekdays excluding holidays

Off Peak – energy use is measured from 7pm until 7am every day and on weekends

Consumers are encouraged to run appliances during these off peak periods to conserve energy and save money. It has worked extremely well for many utilities and pushed high usage activity into lower usage hours.

Data You Can Use to Manage Your Energy Use

The data we have just reviewed is pretty typical of what is provided to consumers by some utilities. The companies that provide heating fuel also provide similar reports as well which can be used to help consumers monitor their energy use.

While it is excellent data, and consumers can use this information to monitor how they are doing, it does not help them save money unless they take action and implement energy use reduction techniques and then look for the results on these reports. For example, the following steps should be taken to reduce energy use:

  • Turn down your thermostat during heating season
  • Turn up your thermostat during cooling season
  • Run your clothes dryer after 7 pm
  • Use your microwave instead of the oven to cook and heat food
  • Cook food in the oven after 7 pm
  • Turn off lights and / or convert to LED’s to reduce energy
  • Run pool motors and spa motors for a few hours every day during off peak times
  • Turn off all unused electronics to further reduce energy

If you take these steps to reduce your energy use, you should be able to see the difference quickly when you look at your energy use data provided by your utility. Some utilities will also provide daily use charts, to help you monitor usage on a daily and hourly basis.

 Graphing Your Usage

Although most utilities will not provide a graph of your energy data, comparing year over year usage on a graph can be helpful to compare your savings and monitor time periods when you are using more energy such as during the summer time when the air conditioning is being used.

We have focused on the energy use data for consumers, however business’s can demand much more information due to the higher level of usage and bills. In fact large companies will even schedule shifts to take advantage of lower rates during the day or weekends.

This is useful information that can be used by all consumers and business owners to monitor the usage and their subsequent energy bills. Monitoring your energy use data is important to control expenses, since it is information that allows you to see what level of energy is being used and allows you to take steps to control how much is used. Take action now by examining your latest bill from your utility.
