Dr. Goto publishes a paper on how Developing Countries can use Energy Efficiency to obtain energy Independence

Dr. Goto, an expert on DSM and energy efficiency programs, has published a paper entitled ‘Establishing Strategic Energy Assessment Indicators for Zimbabwe: A Key to Improving Electrical Energy Efficiency’. This paper focuses on establishing and evaluating indicators that guide correct implementation of energy assessments into Zimbabwean industry. The paper proposes steps that Zimbabwe and other SADC for the alleviation of both shortages in power supply and the capital constraints of building new generating capacity.

Zimbabwe, like most developing countries, can implement high level engineering approaches to identify, calculate, measure, compare and optimize targeted energy efficiency measures – the same strategy being used in the United States and elsewhere. To accurately calculate the extent of energy inefficiency in any plant (or groups of plants) before energy assessments are implemented, energy comparisons in the form of benchmarks may be used. Statistical benchmarking provides indications of sub-sectoral plant-level energy utility by using functional relationships between different levels of energy use. These relationships are used to compute the extent of energy efficiency in a plant before implementing energy assessments, ensuring that the proposed assessments will address specific factors of inefficiency. Using variations of Stochastic Frontier Regression analysis, calculations to the difference in pre and post-energy assessment impact on specific plants can be made. Stochastic frontier analysis is ideal to evaluate the application of energy assessments in particular subsectors within Zimbabwe because it eliminates the need to aggregate diverse industry outputs. For those industrial companies that have clearly defined production outputs, it is desirable to measure energy use relative to a physical measure of production. There are fewer industrial companies that satisfy this criterion in Zimbabwe because of varied product mix and diversity of nontraditional technical approaches employed. Such variations do not easily allow the energy use in these subsectors to be measured relative to diverse measures of physical production, without any assumptions regarding aggregation across those products….

Three impact areas have been identified to create a significant national energy reduction - which Lighting, Motors and Compressed air. Each impact area achieves the highest least-cost savings potential of electricity. A combined savings potential of these three impact areas is shown to be 15.73% power reduction for Zimbabwe’s total industrial consumption.
