Introduction

This report is based on the investigation and research on reducing electricity consumption of certain appliances and to improve energy usage at home. The demand for electricity in South Africa is increasing and it is exceeding electricity supply, research has shown that households contribute 15% to the countries total electricity consumption [1]. Efficient energy usage is very critical; electricity can be used very inefficiently in households during peak load times. In order to tackle this problem the country is facing, this report will give a brief analysis on the usage of domestic electrical appliances and the energy they consume and also identifying the household service using a large amount of electricity so that the service can be modified to reduce the energy usage by 30%. Electricity is high in demand during the peak time loads of 5 pm – 10 pm, and so this research will also focus on efficient electricity usage and how usage can be avoided during peak time loads.

...for the design modifications to be implemented the hot water in the evening has to be used efficiently. The money saved per month will be able to cover the cost of installing the geyser blanket, pipe insulation and the automated timer and some extra money will be saved.
