PURPOSE To highlight the potential of alternative energy solutions and implementation.

BACKGROUND South Africa is one of the role players in the marathon to reduce carbon emissions and develop green economies that are sustainable. This can be achieved by allowing alternative energy resources to co-exist and to be utilized by communities in a sustainable manner. The communities must directly benefit from the development of green economies.

Interventions Retrofitting of traffic lights with LED bulbs Retrofitting of streetlights with HPS and ultimately LED luminaires. Installation of low pressure SWH in the low cost houses (subject to funding). Installation of high pressure SWH in the middle and high income households (subject to funding and/or at cost).

Interventions cont…1 Develop sustainable communities through harnessing a combination of energy resources such as: Solar water heating LP Gas for cooking (should be regulated and aimed at cooking) Energy efficient lighting for public lighting and traffic intersections. Improving the CoT buildings to be more energy efficient.

Approach Coordination: Maximize the potential in using technologies concurrently Encourage community participation through training, employment and SMME support. Improve on consumer education to ignite voluntary migration to renewable and energy efficient technologies. Regulations and by-laws for control.

Energy Savings ProjectPrevious Consumption (Watts) Current Consumption (Watts) Potential Energy Savings (kWh) Streetlight Retrofit12570*0.55 kWh per light per day Traffic Lights Retrofit50 and 75 9Subject to performance routine Solar Water Heaters (Low Pressure at RDP houses) 00**61.9 kWh per month * This is an indication of how much less electrical power is required to operate the new technology. The kilowatt-hour saving is yet to be confirmed by Measurement and Verification experts. ** The consumption of the geyser is non existent as various equipment is used for water heating in the households. This figure excludes energy potential of the entire system and it is seasonal. The above also applies.

Conclusion The savings of the project are measured and verified by the University of Pretoria and Tshwane University of Technology. The reduction in energy demand and efficient utilisation of Eskom energy purchases Reduce energy cost Create employment opportunities through on job training.
