fuel wood provides the main source of energy for cooking and space heating for over 80 percent of households living in kenya. the heavy reliance on the biomass energy has exerted an imbalance in demand and supply consequently resulting in adverse environmental effects in kenya. as part of innovation efforts, several energy-conserving technologies have been developed. a unique cook stove named m...

energy crisis, global warming and other environmental issues are what motivate researchers to find new strategies to reduce energy consumption in buildings. recently, using phase change materials (pcm) in the building’s envelopes has drawn significant attention as an energy-saving method, which helps in increasing the building’s thermal capacity. in the present research, the effects of the main...

This paper presents the energy saving methods and energy storage system to be required for the highly efficient cargo system in container terminal. The best proper method of energy saving is decided by the operation method of cargo handling system and the saving effect of this method is studied. The advantage and disadvantage of battery as energy saving system is studied. The battery in several...

Dumps of a mining-metallurgical complex of post-Soviet Republics have accumulated a huge amount of technogenic waste products. Out of them, Kazakhstan alone has preserved about 20 billion tons. In the field of technogenic waste treatment, there is still no technical solution that leads it to be a profitable process. Recent global trends prompted scientists to focus on developing energy-saving a...
