This study presents an outlook on the renewable energies in Iraq, and the potential for deploying concentrated solar power technologies to support power generation in Iraq. Solar energy has not been sufficiently utilized at present in Iraq. However, this energy source can play an important role in energy production in Iraq, as the global solar radiation ranging from 2000 kWh/m2 to a 2500 kWh/m2 annual daily average. In addition, the study presents the limited current solar energy activities in Iraq. The attempts of the Iraqi government to utilize solar energy are also presented. Two approaches for utilizing concentrated solar power have been proposed, to support existing thermal power generation, with the possibility of being implemented as standalone plants or being integrated with thermal power plants. However, the cost analysis has shown that for 50 kW concentrated solar power in Iraq, the cost is around 0.23 US cent/kWh without integration with energy storage. Additionally, notable obstacles and barriers bounding the utilization of solar energy are also discussed. Finally, this study proposes initiatives that can be adopted by the Iraqi government to support the use of renewable energy resources in general, and solar energy in particular.

Photovoltaics (PV-also called solar photovoltaic devices) are used to harness the power of the sun via the electronic process that occurs within semiconductor cells. The solar energy is absorbed by the cells, which causes the electrons to break away from their atoms, allowing them to flow within the material to produce electricity. This electricity will become the renewable energy for Kentucky, as the generation of coal will but come to a stop within the near future. Like Denmark who is running on 100% renewable generation we must stride to become fully operational on solar. In the present work, we systematically studied about renewable energy resources, in particular, solar energy for the application of photovoltaic panels in Eastern Kentucky. By analyzing data from our PV cells at Morehead State University designed to follow the direction of the sun for optimized output and by incorporating MPPT charge controllers, we have constructed a maximum power algorithm that performs best for the location. Utilizing these, measurements of daily electricity production in comparison to the average power needed for household use has validated our research. With the advancements in solar cell technology what was once impossible is now reality, as solar power can easily power this region based on our data. Knowing this, being a prime location we can now push to enable the advancement of renewable energy production and become less dependent on fossil fuels, thus creating an infrastructure that will run off solar power.

As the Egyptian population is increasing at a huge rate, the yearly housing demand is increasing in an equivalent rate. In addition, the whole world is suffering from an energy crises caused by the rapidly increasing consumption of world’s traditional energy resources, so the obvious solution is to go green, and depend much more on renewable energy resources. According to the statistical data available in Egyptian governmental authorities, the accumulated housing demand till 2014 was about 2,400,000 units. On the other hand, the yearly housing supply from private and public sectors is about 150,000 to 200,000 unit, Egyptian authorities declared that at summer 2010 air-conditioning devices increased to reach 3.000.000 ( three million) devices all over Egypt, mostly working from early mornings till 2 am next day to adjust temperatures that reach up to (45C) and more outside buildings to reach (25 C) or less inside. This behavior increased electricity consumption rapidly. Consequently, the electricity consumption rate in Egypt had increased by 13% more than 2009, which exceeds the maximum capacity power of the high dam by 7% to 8%, ministry of electricity announcements declared that to fill that gab we need 3000 megawatts at peak hours which costs the electricity sector up to 16.000.000.000 l.E. Accordingly, a new architectural design concept is proposed (Zero-Energy Housing Unit) to rely on the surrounding environmental conditions and new Green Architecture Techniques in order to provide human comfort based on renewable energy sources, provided that the common current governmental energy sources will be a backup system for the meanwhile.

Owing to rising population and increasing energy demand, renewable energy resources become the most convenient and promising solution. Hence, solar power plant investments and photovoltaic module numbers have risen sharply. Turkey is one of the tight followers of the energy trends, thanks to its rising energy demand and economic power. However, the consequences of the massive plant wastes importance in term of economically and environmentally have not been understood yet. Almost 70% of the modules are formed by glass and the rest accumulates economically valuable metal materials, which are silver, aluminium and copper. These three main materials are substantially important in the overall waste. Not only the economic value, but also the environmental impacts of the mining effluents to excavate these metals are causing emission problems. As a chain reaction, the higher energy demand triggers a search for new and renewable energy resources. This is why popularity of solar energy has increased. Solar energy can be absorbed and transformed through photovoltaic modules, which contain glass and three main metals. In order to respond for the production of modules, metals are fundamental. This need triggers the need of metals mining excavations and emissions. In this respect, in the near future, thanks to the rising investments on photovoltaic modules and the CO2 emissions coming from mining, the wastes of photovoltaic modules and the need of recycling will become more important. That is why, in this study it is aimed to present environmental benefits and economic recoveries of recycling photovoltaic module in Turkey.

Electricity is the engine for the growth of economy of any country. Total installed electricity generation capacity of Pakistan is presently approx 20,000 MW as given in Table-1. Despite this, almost 40% of the population is without electricity. Pakistan has been blessed with tremendous resources for electrical power generation with hydel, coal, renewable energy resources and Nuclear power. Hydel, coal potential of more than 40,000 MW and 10,000 MW are available but only 15% of hydroelectric potential has been harnessed so for where as only 150 MW power plant on indigenous coal has been set up. To exploit Pakistan hydel and coal resources for power generation large investments are needed which Pakistan economy can not afford. Govt. of Pakistan has created an organization of private power and infrastructure board (PPIB) to facilitate private sector in the participation of power generator. PPIB is tapping the resources and facilitating the private sector for establishment of power projects. Pakistan is collaborating with China for establishment of Nuclear Power Plants and plan to generate up to 10,000 MW by year 2025. Renewable energy resources are also required to be tapped. This paper will focus on the Pakistan power generation potential by utilizing local resources keeping in view the next 20 year supply and demand position.

Starting Point

Just as with other Southern African Development Community (SADC) countries, Mozambique faces severe, interrelated problems of energy and environment linked, with massive consumption of fuel wood biomass. The conventional power grid provides less than 7% of the energy needs for the country’s 17 million inhabitants, and about 83% of the energy consumed in the country comes from biomass. Renewable energy resources can play an important role in the process of development of the country. From the vast renewable energy resources available in the country, solar energy represents one of those with the highest potential. Thus, the evaluation of the potential of solar energy systems in small-scale applications suitable for villages is a strategically good starting point for promotion of sustainable rural development. One of the major impediments in carrying out such studies is the fact that the exact behaviour of solar energy resources throughout the country has not been well studied. In this paper a general characterisation of the global, diffuse and direct solar radiation fields in Mozambique is presented. The study is based on experimental data measured by the National Institute of Meteorology (INAM) in the period 1970- 2000. For these analyses global, diffuse and direct solar radiation data from three stations along the coast line and three stations in the interior of the country have been used. The six stations were representative of the three main regions of the country, namely south, centre and north. Furthermore, sunshine hours data of one selected station was analysed.

In this paper, we conclude that Indonesia has vast potential for generating and balancing solar photovoltaic (PV) energy to meet future energy needs at a competitive cost. We systematically analyse renewable energy potential in Indonesia. Solar PV is identified to be an energy source whose technical, environmental and economic potential far exceeds Indonesia’s present and future energy requirements and is far larger than all other renewable energy resources combined. We estimate that electricity consumption in Indonesia could reach 9000 terawatt-hours per year by 2050, which is 30 times larger than at present. Indonesia has abundant space to deploy enough solar to meet this requirement, including on rooftops, inland reservoirs, mining wasteland, and in combination with agriculture. Importantly, Indonesia has a vast maritime area that almost never experiences strong winds or large waves that could host floating solar capable of generating >200,000 terawatt-hours per year. Indonesia also has far more off-river pumped hydro energy storage potential than required for balancing solar generation.
