The quest for other alternative and sustainable energy prompted the feasibility assessment of Zobe dam meant for irrigation to  produce electricity; In this write-up the scheme is designed to operate with two turbines; turbine T1 to operate all year round to take account of the irrigation need downstream, The second turbine T2 will operate on a spill discharge, and to be available for four months with a generation capacity of 0.969 MW. T1 is expected to discharge 55,500,000m3 within six months to cater for irrigation need with an average discharge rate of 3.6m3 /s. it was found that, the dam has the potential to generate a minimum 0.671MW all year round and a maximum of 1.5MW of power during Peak discharge period. The scheme was designed with minimum modification of the existing infrastructure at site which translate to minimum cost implication in construction, system operation and maintenance.

The potential for mining companies to contribute to sustainable energy development is characterized in terms of opportunities for energy efficiency and support of electricity access in mining-intensive developing countries. Through a case study of the Central African Copperbelt countries of Zambia and the Democratic Republic of Congo, energy efficiency opportunities in copper operations and environmental impact of metal extraction are evaluated qualitatively, characterized, and quantified using principles of industrial ecology, life cycle assessment, and engineering economics. In these countries the mining sector is the greatest consumer of electricity, accounting for about 53.6% in the region. Energy efficiency improvements in the refinery processes is shown to have a factor of two improvement potential. Further, four strategies are identified by which the mining and technology industries can enhance sustainable electricity generation capacity: energy efficiency; use of solar and other renewable resources; share expertise from the mining and technology industries within the region; and take advantage of the abundant cobalt and other raw materials to initiate value-added manufacturing.

Gauging Station

In August 1979 a glacier outburst from Flood Lake, British Columbia, released 150 × 106 m3 of water. The resulting flood was routed through the Stikine River and yielded a maximum discharge rate of 1200 m3 s−1 at a gauging station 90 km downstream from the glacier dam. We have used a computer model to simulate this outburst in order to test the usefulness of the model as a predictor of flood magnitude. The predicted peak discharge is 2160 m3 s−1 at the outlet tunnel of the ice dam and 1700 m3 s−1 at the gauging station.

City Water

We evaluated the feasibility of waste-generated heat using a 100-kW digestion gas engine at the Karatsu City Water Purification Center by evaluating its disaster resilience through four indicators. We achieved the best outcome, i.e., a power generation rate of 1,122 kW and a power self-sufficiency rate of 22% when two or more digestion gas engines were installed to supply waste-generated heat to the absorption chiller/heater of a water-pool. Additionally, we evaluated the environmental and economic aspects of a Mechanical Biological Treatment (MBT) system installed in Karatsu City. The results suggested that by installing an MBT system, the annual cost could be reduced by ∼100 million Yen and the power generation capacity could be increased to 4,310 kW; this could also help reduce 19,000 tons of annual CO2 emissions with increased power generation. The environmental and economic feasibility assessment tool developed here is configurable; hence, applicable to other regions.
