Use of Distributed Electricity Generation Technologies in Hotels
- Authors: John Vourdoubas
  First page: 1
  Abstract: Distributed electricity generation technologies have increasing applications worldwide in various sectors due to their environmental and economic benefits. In the present study the use of these technologies in hotel industry is investigated. Various distributed electricity technologies, including co-generation of heat and power systems, are examined. Some of them are using renewable energies like solar energy, wind energy and biomass for electricity generation. Others are related with various co-generation systems including fuel cells. Many hotels require almost equal amounts of heat and electricity in their daily operations. Co-generation technologies have the advantage that they can cover almost all of their requirements in both electricity and heat. Some distributed electricity generation technologies including solar photovoltaic energy, co-generation systems, wind turbines and fuel cells are already used in hotels. Their energy efficiency varies in the range of 10% to 90%. Technologies using renewable energies generate carbon-free electricity while others fueled by natural gas generate electricity with low carbon impacts. Each technology has advantages and drawbacks while the possibility of using each technology depends on hotel’s characteristics as well as on the local availability of renewable energy sources. The results of the present study are important in hotel industry since they indicate the possibility of using the environmentally friendly distributed electricity generation technologies for covering their electricity as well as, in some cases, their heating requirements reducing their carbon footprint due to energy use and increasing their energy and environmental sustainability.

Exploring Plantation Development and Land Cover Changes in the Meme-Mungo
Corridor of Cameroon
- Authors: Cletus Fru Forba, Jude Ndzifon Kimengsi
  First page: 15
  Abstract: There is an apparent nexus between the development of plantations and changes in landcover. The Meme-Mungo Corridor is an example par excellence of a tropical plantation corridor in Cameroon which has witnessed significant expansion in tropical plantations of cocoa, banana, rubber and oil palm, among others. This paper analyzes the connection between land cover changes and plantation development over a 42-year period (1960 and 2012). A total of 100 households were sampled using the systematic sampling technique. Furthermore, multispectral data, obtained from the Global Land Cover Facility (GLCF, 2005) were used in the classification of the study area. These images were processed using Geographic Information System (GIS) and Remote Sensing (RS) software and further compiled into a GIS database using ESRI ArcGIS software. The results showed that between 1960 and 2012, a more than 50% increase in the surface area of plantation crops was registered, leadingto a corresponding change in the land cover situation. Based on this, the study probed into the implications of further plantation development on land cover; further land cover changes could be attributed to the extension of plantations. This paperrecommends among others, the need for intensive agriculture to be encouraged so as to ensure an increase in agricultural output against the backdrop of a decline in agricultural space. Furthermore, augmenting agro-product value chains will stem the loss of agro-produce due to perishability. This will contribute to regulate extensive plantation development in the area.
