Domestic Sector Energy Requirements

Ellie Dodds

2E02

Group D

February 24th 2005


Assumptions and other factors

  • Replacement Rate of houses:

    • 50,000 -100,000 new, more efficient houses built each year

    • Conservation effects from this not seen till after 2010

  • Conservation measures:

    • In 1987 only 3% of homes had full insulation

    • In 2002 this had gone up to 15% of all homes

  • Lighting and appliances have all made homes use more energy

    • More homes have central heating


Factors Affecting Future Energy Use in the UK Domestic Sector

  • Size of population and number of households

  • Average Area of each household

  • Comfort level desired by each household

  • Demand for non-space heating process (water heating, cooking, appliances) by each household

  • Efficiency with which energy is used to meet space and water heating demand


Projection of UK population and number of households 1985-2010

From Energy Use and Energy Efficiency in the UK Domestic Sector up to year 2010.


Electricity Consumption by household Domestic Appliances by broad type, 1970-2002

  • Key

  • Lighting

  • Brown: TV, VCR, DVD player, Satellite, Cable

  • Cold: Freezers, Fridges etc

  • Cooking: Ovens, Microwaves

  • Wet: Washing machines, Dishwashers, Tumble Dryers

  • Miscellaneous: Vacuums, Irons, Electric Showers, Central Heating pumps

  • From www.DTI.gov.uk


    Domestic Sector Split into fuel type

    • Coal, Oil, Gas and Electricity are all used in the domestic sector for various purposes

      • Coal is used in homes for heating-open fires

      • Oil is used in Central heating

      • Gas is used for Central heating, both oil and gas consumption are dependent on external temperatures

      • Electricity is used for running domestic appliances
