Recently, the technology of floating photovoltaic panels has demonstrated several advantages over land installations, including faster deployment, less maintenance cost, and higher efficiency. Lake Nasser is the second largest man-made freshwater lake in the world with a surface area of almost 5000 square km. Being in one of the hottest areas in the world, evaporation of water causes loss of very precious and scarce resources: freshwater. Fortunately, the lake is also located in a very rich area in solar energy. This paper presents a study to utilize Lake Nasser’s surface for massive production of solar energy, while significantly reducing the loss of water by evaporation from the lake surface. The project has the potential to be one of the largest producers of low-cost clean electric energy in the world for Europe and the Middle East and North Africa (MENA) region, especially with the ongoing efforts to connect the North African countries with the European super power grid. The study shows that the first phase of the project is expected to deliver about 16% of European need of electricity and save about 3 billion m3 of freshwater. The subsequent phases will provide low-cost green energy to replace the combustible fuels in Europe by 2045, while saving up to 10-12 billion m3 of freshwater lost by evaporation from Lake Nasser.

Global warming affects everyone, and the effects will be more dangerous all over the world in time. Therefore, it is very important to use our world's limited resources and to prefer the renewable resources such as solar energy and wind energy. In this study, the authors consider an elevator system, which includes a solar-powered and conventional one with some new Internet-of-Things (IoT) features. The elevator may be operated by both electric energy and solar energy. Solar energy, as being a renewable energy source, leads to various benefits. Internet-of-Things-enabled elevator has a global system for mobile communications (GSM) module to send messages to pre-specified receivers in case of a power failure. The target performance measures are defined, and the advantages of the solar-powered smart elevator are explained.

Water pumping for irrigation has a relatively high energy demand, depending on the applied irrigation method. At the same time, there is a considerable energy from the sun during the irrigation period. The solar PV (photovoltaic) technology may be suitable to ensure electric energy for pumping in many cases in agriculture, where the electric network is not available or reduction of the energy costs is wanted. There are some pilot plants for water pumping on the base of solar energy in the world and the spreading of these solar technologies is predictable. The solar energy based pumping process can be approached both in theoretical and experimental ways. In this paper, both the theoretical questions of the solar based pumping process and the experimental results of a model testing pump station powered by PV panels are shown.

Strictly speaking, all forms of energy are derived from the sun. However, our most common forms of energy, fossil-fuels, received their solar input eons ago and have changed their characteristics so that they are now in concentrated form. It is apparent that these stored concentrated energy forms are now being used at such a rapid rate that they will be depleted in the not-toodistant future. It would be useful to utilize the incoming solar energy directly. The effective use of the sun's energy in agriculture by any economically possible means will help the farmers continue their work with no disruption because of the lack of concentrated form of energy. The fluidyne heat engine utilizes solar energy to pump water. The simplicity, reliability, and low cost of this engine are of primary importance for the farmers in the part of the world whereas solar energy is abundant such as Puerto Rico.

Renewable And Sustainable Energy

The present work aims to exemplify a renewable and sustainable energy source as such the energy from sunlight to drive mobile coverage as a clean source of energy that does not cause damage to the environment, taking advantage of solar energy as a source of heat and light being one of the most propitious and reliable energies in the world. With the installation of solar panels at the roof top of houses, industries and plantations, the energy captured by the photovoltaic solar panel is sent to the load controller that powers the battery and the frequency inverter energizes the motor , allowing the activation of the cover with the objective of bringing greater comfort and satisfaction of our final client, people who want to have comfort in relation to their roofs, taking advantage of more than nature has to offer us, not only in homes but also in areas of leisure and entertainment, sheds, plantations and many other places that needs a roof, with the purpose of taking advantage of the sunlight, also saving the electric energy by making people aware of a more sustainable and renewable country. It is worth mentioning that in case of rain-sensitive plantations with the mobile cover, it will not be necessary to move to totally enclosed sheds, but in sheds using a structure such as that of the moving roof

Energy-efficient technologies provide chances for money savings and reducing environmental damages related to energy use. This paper aims to assess the energy efficiency in Libya and tools to promote its implementation. In addition, it seeks to present measures and programs that could be foreseen in the transformation sector and some end users. Data of energy intensity in Libya was taken from different recognized sources such as World Development Indicators (WDI) - World Bank, and Enerdata web site. The data was collected, assembled, and analyzed using Ms Excel sheets. Results were plotted and compared to World average and Africa or with (Middle East and North African) MENA countries where ever data is available. The main indicators over almost quarter of a century (1990-2014) were presented and changes over this period were indicated. It could be concluded that primary energy intensity for Libya during (2000- 2014) is comparable to world average values and for Africa and the final energy intensity has increased at only 0.7% per year during the same period. As an oil producer and exporter country, the ratio of final enrgy intensity to primary energy intensity in Libya has increased at a rate of 1.1% during (2000-2014), which is greater than the World average and African countries.  The rate of energy intensity of transport has increased by 6.9 % per year for the period (1990-2014) and 7.8% per year for the period (2000-2014) compared to the world improvement (-1.8%) per year and for Africa (-0.3) % per year for the period (2000-2014)). This is due to lack of regulations and measures concerning this sector and increased number of private cars. Suitable measures and policies should be taken towards this sector to improve its performance since it contributes to the highest share of energy consumption. The highest share of electric energy consumption is at residential, then commercial and service end use, followed by street lighting. There is a good potential for energy saving at these sectors.

Development Gap

Since the 1980s, the world has changed because of the globalization in every aspect of life. Globalization has some impacts, both in positive and negative. Globalization makes it easier to trade between countries, investment, the expansion of MNCs, low-cost travelling, communications, information access, and other things. Globalization also makes easier for the MNCs to build up their factories and sell their products across the world. But, on the other side, globalization resulted in the development gap between Northern countries (US, UK, Japan, and Australia) and the Southern countries (Latin America, Africa, South Asia, and the others). The impacts mentioned earlier happened because of globalization, which is conducted mostly by the Northern countries that built factories in the Southern countries to push the production cost, get a lot of resources, and cheap labour wages. By the impacts of globalization and the formation of MNCs that led into the North-South development gap, the writer aims to analyze by using the dependency theory on explain about the case as a general.
