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.

SWH System

Energy Savings

Project Previous Consumption (Watts)

Current Consumption (Watts)

Potential Energy Savings (kWh)

Streetlight Retrofit 125 70 *0.55 kWh per light per day

Traffic Lights Retrofit 50 and 75 9 Subject to performance routine

Solar Water Heaters (Low Pressure at RDP houses)

0 0 **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.

Traffic Lights

Traffic Lights & Streetlights

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.
