  4. How much energy do electronics and computers consume?

    Consumer electronics and computer equipment now represent 15% of home electricity consumption. Energy used by these devices is expected to triple by 2030 unless actions are taken to increase energy efficiency.
  5. How many units of energy (kWh) do I consume annually and how much does it cost?

    We suggest you refer to your quarterly electricity and/or gas bill. As well as informing you how much you need to pay, the invoice/statement will also indicate you how many units of energy you have used in the last quarter. As there will likely to be seasonal changes in your usage, your bill in the winter is likely to be more than your bill in the summer. We suggest therefore you keep all 4 quarters bills to calculate how many energy units you're using in a year. If in doubt, please call your energy provider who will have a record of how much you have used and spent.

    If your property is heated by oil, to calculate the number of energy units (kWh), simply multiply the number of litres of oil you use in a year by 10.35 which is the conversion factor of litres into kWh. So a property which consumes say 2,000 litres of oil per year will have an energy requirement for space and hot water heating of 20,700 kWh.
