The conservation of energy is an essential step we can all take towards overcoming the mounting problems of the worldwide energy crisis and environmental degradation. In particular, developing countries are interested to increase their awareness on the inefficient power generation and energy usage in their countries. However, usually only limited information sources on the rational use of energy are available. The know-how on modern energy saving and conservation technologies should, therefore, be disseminated to government and industrial managers, as well as to engineers and operators at the plant level in developing countries. It is particularly important that they acquire practical knowledge of the currently available energy conservation technologies and techniques. In December 1983, UNIDO organized a Regional Meeting on Energy Consumption as well as an Expert Group Meeting on Energy Conservation in small- and medium-scale industries for Asian countries. During these meetings, it was brought out that, for some energy intensive industries, savings up to 10% could be achieved through basic housekeeping activities, such as auditing and energy management. All these experiences brought UNIDO to prepare a regional programme on the promotion and application of energy saving technologies in selected subsectors, since the rational use of energy calls for a broad application of energy conservation technologies in the various industrial sectors where energy is wasted. One of these energy intensive industrial sectors to be considered to improve efficiency through the introduction of modern energy conservation technologies is the cement industry. The cement industry consumes much energy. The cement industry is also noted for great percentage of the energy cost in the total production cost. In the cement industry, appreciable amounts of energy could be saved or conserved by preventing of leakage in the kilns, modifying the equipment to recover heat from the preheater and cooler in the process of cement-making and effective use of industrial waste materials. Currently, UNIDO is implementing this programme with the financial support of the Japanese Government, in selected Asian developing countries. This programme aims at adapting these innovative energy conservation technologies, developed in Japan, to the conditions of developing countries.
In this programme, we are considering that the transfer of these technologies could be achieved through: (i) (ii) (iii) (iv) Conducting surveys of energy usage and efficiency at the plant level; Preparing handy manuals on energy management and energy conservation/saving technologies, based on the findings of the above survey; Presenting and discussing the handy manuals at seminars held for government officials, representatives of industries, plant managers and engineers; Disseminating the handy manuals to other developing countries for their proper utilization and application by the industrial sector. The experience obtained through this programme will be applied to other programmes/projects which involve other industrial sectors as well as other developing countries and regions. UNIDO has started this programme with the project US/RAS/90/075 - Rational Use of Energy Resources in Steel and Textile Industry in Malaysia and Indonesia and the project US/RAS/92/035 - Rational Use of Energy Saving Technologies in Pulp/Paper and Glass Industry in Philippines and Thailand. These were followed by project US/RAS/93/039 Program for the Use of Energy Saving...
