Measure Energy Use

 

Measuring and recording your energy use is a key aspect of energy management and the first step in identifying possible savings. There are various ways to monitor your energy use:

Energy Bills

Reviewing your energy bills e.g. electricity, natural gas, liquid petroleum gas (LPG), heating oil or wood pellets, is the quickest and easiest way of determining your annual energy use. It is a good idea to keep track of your energy bills in your co-ordinators workbook and to collect as much information as possible from them. See below for a bill tracker tool and a factsheet on understanding your bills.

Meter readings

You can also use readings from electricity or gas meters to look at usage on a daily, weekly or monthly basis. This information allows you to measure the success of the energy saving measures you are implementing. You can involve pupils in this task if the meter can be accessed safely by them. See below for a spreadsheet to record and graph readings and a film clip of pupils reading the meter. See also the following factsheets for guidance on reading meters:

Display energy monitors

Display energy monitors can be used to give you a reading of how much electricity you are using at a given time. You can track the electricity used by various appliances and compare different appliances’ energy use as they are switched on or off. This will assist you in identifying how to save money simply by using these appliances less or turning them off. This can help you compare your daily habits and to track the savings that you are making. See below for a case study on how a school used these monitors for energy management.

Keeping track of energy use

The information you collect from bills and meter readings can be recorded using the workbooks for co-ordinator’s and pupils in the Energy Education Pack or you can download and use the spreadsheets below. The different types of energy you use such as electricity, oil or gas may be measured in different units such as kilowatt hours(kWh) of electricity or litres of oil. It is best to convert all units into kilowatt hours and this can be done using simple conversion factors. See below for a fuel conversion calculator.
