The objectives of the study are to: determine solar energy, biomass based fuels, small hydropower schemes and wind energy sources that can be used to replace the regular fossil based fuels. An experimental model was established using the Bayesian decision model to ascertain the econometrics of the said energy technologies & applications for the communities in Ogor Kingdom, southern region, Nigeria. The model formulated was gotten from the data derived from Bill of Engineering Measurement and Evaluation on net benefits to the community persons after the projects were designed & constructed for...

The Book investigated; Human related activities, burning of fossil fuel, greenhouse gas emissions and construction activities that led to variability in rainfall, temperature and other climatic conditions; organizational inadequacies to manage uncertainties, projections and scenarios in climate change; financial constraints, lack of logical cost sharing in multipurpose dam projects resulting to food insecurity, deforestation, flooding, erosion induced gullies, unbalancing of the ecosystem, pollution of air, land and water, human suffering, loss of lives and properties at the south-eastern...

The Book is aimed at studying solid waste, recovery, reduction & recycling to wealth at Enugu Urban using indirect method of Newton-Raphson algorithm. The objectives of the study are: to review existing municipal solid waste management in Enugu urban, to quantify solid waste volume in Enugu urban, to determine the characteristics of solid waste generation in Enugu urban, to apply Jacobi's Iteration Model as the best waste management system for Enugu urban, to develop the optimization models and the cost effective solid waste planning & management system for Enugu and to convert waste to...
