Cellular networks are now rapidly evolving to the renewable heterogeneous network (HetNet) architectures, where a mixture of macro base stations (BSs) and small cell BSs coexist. Particularly, these BSs are partly-powered or self-powered by renewable energy sources (RES). In this context, joint user association and resource allocation is challenging. In addition, wireless backhaul is rapidly be...

Woody biomass is an abundant renewable energy resource in Sweden, and the Swedish government has been promoting research and development programs for the exploitation of this resource as a means to meet the targets on the reduction of the carbon dioxide emissions from the industrial, energy and transportation sectors. This thesis aims at expanding the knowledge on the efficient utilization of t...

Abstract Step by step the energy request is broadening and in this way necessities for a manageable source that won’t hurt climate are of prime significance. Several projections express 2050 requesting will basically increase. In any case bigger part fulfilled oil subordinates yet utilization innocuous to environment power designs could help giving requests. As we general understand feasible wh...

The aim of this article is to review issues related to the incorporation of scarce natural resources in the theory of economic growth and development. More specifically, we shall concentrate on the role of non-renewable resources. A nonrenewable resource is a natural resource the amount of which on earth is finite and which has no natural regeneration process (at least not within a relevant tim...

This work is about an appropriate choice of a renewable energy source between a wind turbine and a solar power plant. The selected renewable energy source should supply electricity to a site, part of the University Alioune Diop of Bambey, in Ngoundiane, Thies region. The work is based on analysis of meteorological parameters (wind speed, ambient temperature, solar irradiation). According to thi...

A recent trend in the design of hybrid energy systems is the development of standardised systems, which can support a variety of applications. The performance of parallel hybrid energy systems can be improved through the application of advanced control methods implemented by a centralised system controller. Optimum resource allocation based on load demand and renewable resource forecast, promis...

PURPOSE We have experienced a major fall in the economy in the recent past. We need something to help boost the economy. Our non-renewable sources of energy are also running out. We desperately are in need of an alternate renewable clean resource for energy. In doing this project, the researcher hopes to find the most efficient combination of blade angle and width on a wind turbine. HYPOTHESIS ...
