Energy in the home-personal energy use-energy efficiency

Energy in the home personal energy use and home energy efficiency.

Estimate your personal Annual Energy Usage for the following - list all data in kWh (KiloWatt hours):

Space Heating (Central heating, room heaters etc. - if you share a central system, e.g. in a flat or Hall, estimate your personal use).

Space cooling (if you have air conditioning at home)

Cooking (Gas cooker, microwave, sandwich toaster, toaster etc.)

Lighting (All lights in your house/flat)

Other domestic use (TV, Electronics, including computers, X-box etc)

Transport (Public transport/car/motor cycle, including air travel if used)

Total ______________kWh

Then convert this figure to kg of CO2 (Carbon dioxide) and Tonnes of Oil Equivalent (TOE). State clearly the basis for your calculations.

If you use a web based calculator you should check that the conversions are appropriate for your location.

(If the calculator does not state conversion factors, you can usually determine them by putting single inputs (e.g. 1000kW electricity) into calculator and seeing what the output is).

TOTAL (kg of CO2)........................................

TOTAL (TOE)...................................................

The average UK per capita consumption is ~4TOE/annum,

The average UAE per capita consumption is ~11TOE/annum

Suggest why your figure might differ significantly from this.

(You may want to list, but not quantify, some major indirect uses of energy) 3

NOW:

(a) Identify one item of energy saving equipment which you could incorporate in your house/flat/room or apartment block to replace one of your existing items mentioned above.

(You will receive higher marks, in general, if you successfully address a more sophisticated energy saving measure than low energy light bulbs!)

(b) Estimate the installed cost of the item and the annual savings (energy and financial) which would result.

(c) Hence estimate the simple payback period.

(d) Why have you not installed this equipment? (Note: if you live on Campus or rent a room, imagine you are the owner the flat apartment block etc. when answering this question). 4
