- Description: Efficient energy use, sometimes simply called energy efficiency, is the goal to reduce the amount of energy required to provide products and services. Lack of efficient process skills, education and training has become a major issue in recent years regarding the up-stepping of energy efficiency in steel industries. This paper highlights the overview of the current state of energy efficiency in South African foundries, improvements made and challenges faced by the foundry industry in South Africa upon implementation of energy efficiency. In this paper we acknowledge the need for studying the current energy consumption and the improvement that has been done in order to analyse the problems of implementation. Barriers studied are: lack of capital, resistance to change, uncertainties and attitude. An active interaction between the academia and foundry industry (men) will further enhance suitable skills to move South African steel foundries in to an energy efficient industry.

- Description: Mitigation of CO2 emission is the Lessing of CO2 produced that have or could have a serious threat on climate change. South Africa is known to have a coal addiction. This paper attempts to identify the major opportunities for climate change mitigation through foundry energy efficiency. It does so by analysing key areas of carbon and energy efficiency policy in South Africa. The report further considers a number of important areas concerning future carbon and energy efficiency policy development in the country. Electricity generation and renewable energies are clearly discussed with their advantages and dis advantages in the operation of foundry industry; furthermore it highlights the effect of burning of coal on climate change raising regulation such as carbon tax to be proposed to reduce the growth of CO2 emission. Mitigation of CO2 through foundries by using best energy efficiency practices is highlighted as part of assisting in fighting excessive CO2 emission.

- Description: Due to the low reserve margin on the electrical grid in South Africa many energy initiatives were introduced by the utility over the last decade. One such initiative was to roll out identified energy efficiency technologies at residential homes. The utility aimed to achieve a 90MW evening peak (18h00 to 20h00) demand reduction by distributing free CFLs, LEDs, geyser timers, pool timers and low flow shower roses to residential electricity customers throughout the country. This paper presents an overview of the process and methodology used to measure and verify (M&V) the energy and demand impact of the programme. The verified saving achieved was 87.2MW. This includes both an energy efficiency and a load shifting component. The project was M&V’d using the International Performance Measurement & Verification Protocol (IPMVP) and SANS 50010 standard for determining energy savings.
