Abstract: The paper offers an outline of Gasification technology, starting from basic aspects of the process and arriving to a comparative examination of Gasification and Incineration and the environmental applications of Gasification technology for Municipal Solid Waste management (MSW) and also considered limitations of Gasification Technology. Gasification is waste to energy technology that is able to convert a variety of waste materials into renewable and alternative energy products. The technology can process nearly any carbonaceous material, transforming it into forms of usable energy that can be consumed or sold easily. This review paper indicates that Gasification technology can help the world both manage its waste and produce the energy and products needed to fuel economic growth. It is able to meet existing emission limits and can have a remarkable effect on reduction of landfill disposal option.

Abstract: The positive-negative parity states, potential energy surfaces, V(β, γ), transition probabilities, B(E1), B(E2), staggering effect and electric monopole strength, X (E0/E2), values of 154Gd have been calculated within the frame work of the interacting boson approximation model (I BA − 1). The results obtained are compared to the available experimental, theoretical data and reasonable agreement has achieved. The potential energy surfaces, levels energy and transition probability ratios show that 154Gd is an X (5) candidate.

Abstract: The energy and exergy efficiencies of a stationary solar cooker equipped with an asymmetric compound parabolic concentrator (CPC) were experimentally evaluated. Experiments were conducted with different water load and at different ambient temperature. It was found that it is preferable that the cooker is directed 30° east of south for an exploitation during morning at a lower ambient temperature with sufficient solar radiation on its intercept area. Also exergy efficiency together with energy efficiency is used to define the optimum water load of the solar cooker. This optimum load is calculated according to 5 kg water/m² intercept area.

Abstract: Population growth, technological advances and increased demand for energy, has been made the world faced with a major crisis which called energy crisis. Using renewable energy as a permanent and proper solution is to deal with this crisis issue. The Environmental sustainable availability, diurnal fossil fuel reducing and increasing emissions from fossil fuels, has been actuated world to use renewable energy sources. Economic growth, innovation in technology and public health undoubtedly is dependent on the manner and extent of energy consumption of countries. In this article we will briefly review the amount of produced energy from renewable energy sources in the world and finally the use of these energy sources as a major step forward for community health and energy crisis and shortage of fossil fuels will be introduced.

Abstract: The aim of this study is to establish the wind power potential for the wind energy resource in Enugu, south east Nigeria. For this purpose, monthly wind speed data were obtained at 10m height from Nigeria Meteorological station NIMET, Abuja for the period (1990 – 2006). The monthly average values of wind speed, standard deviation, Weibull parameters and wind power were determined. The Weibull and Rayleigh probability density function and the cumulative distribution function respectively were also evaluated. The results show that this region, according to wind power classification is in wind power class II because values of wind power density is greater than 100W/m2. From the results obtained electricity generation from wind power is quite promising for the installation of wind turbines.
