Monitoring and metering your energy use

Analyse and monitor energy use

Once you have collected your energy usage data you can analyse the energy spend for the business as a whole by:

  • converting all energy sources to the same unit (kilowatt hours)
  • using a spreadsheet to analyse the use of each energy source on a month-by-month basis
  • calculating energy costs at different intervals to use as a benchmark to measure energy-saving improvements
  • identifying and measuring the factors, such as weather conditions, that cause your energy use to vary

From this you can see:

  • if you're using too much energy
  • how your current energy use compares with past figures
  • how your business compares with the industry average if benchmarks are available
  • the impact of the factors that affect your consumption

You can also do a more complicated analysis to show the impact of the factors that cause your energy consumption to vary. Read guidance on analysing your consumption data with worked examples on the Carbon Trust website.
