Recent patents on water desalination by using renewable energy technologies are critically reviewed with highlighting on environmental impacts and sustainable development. An overview of using wind, hydroelectric, wave and tidal, wind/solar, geothermal, and solar renewable energy technologies for desalinated water production are assessed. Solar energy is the mother of all other renewable energies; it does not pollute, it is free and available everywhere. Several patents have been invented systems and methods that collected and converted solar energy to electrical energy via solar energy which can be used for water desalination. Wind farm with wind-driven pressurizing devices is used to desalinate salt water by reverse osmosis. Geothermal has been used as an effective method for water desalination. It is highly recommended to provide seawater desalination powered by a renewable energy source in remote areas. On the other hand, sequentially staged of energy conversion steps operate at low efficiencies.

Proposed Model

The purpose of this study is to identify the most relevant renewable energy technologies for buildings and to assess the effectiveness of their implementation in the long term for Kuwait. Methods of analogies and comparisons were used to determine the features of energy efficiency based on the technologies under study. The study proposes the methodological approach to assessing the effectiveness of the introduction of renewable energy technologies, determining the direction of increasing the energy efficiency of buildings and the investment efficiency of introducing these technologies. Renewable energy efficiency analysis for buildings in Kuwait confirms that solar energy systems have been the most widely available for widespread use of solar energy over the past three years. An increasing level of energy efficiency with a decrease in the notional cost of increasing energy savings is characteristic of solar collectors with booster reflectors. The proposed model for assessing the level of energy saving provides an opportunity for economic justification of introducing renewable energy technology in buildings.

This research investigates the factors that potentially affect public attitudes and their adoption of renewable energy technologies for electrical energy production in Afghanistan. The study is carried out with a survey from Kabul and its neighboring provinces including Logar, Maidan Wardak, Nangarhar, Ghazni, Parwan & Kapisa provinces. We used a random sampling process to collect data using a web-based questionnaire. The survey was well designed to highlight conveniently the public understanding, willingness, and attitudes toward adopting renewable energy technologies (RETs). The outcome of the survey is then evaluated to discover the most potential factor affecting public acceptance of RETs. The results declared that the educational level, expertise in RETs, and income of respondents are positively related, while the age of respondents is negatively related to the public willingness on the use and investment in RETs. The majority of respondents have used one type of RETs, however, 23 % of respondents have not used any type of RETs. Study shows that the RETs use and access to grid electricity are reversely related, where the access is lower, the RETs use is higher and vice versa. Most of the respondents were not well informed and most disagreed with the government policies on RETs, therefore, public awareness programs on RETs and government policies are recommended. The majority of respondents were willing to invest in RETs, therefore, the government should commit itself and support private sectors to invest in RETs and take part in its development.

Hotel accommodation in Nigeria is comparatively more expensive than its neighbours in the sub region of West Africa. It is one of the most expensive globally. This is attributable to its operating environment. Any sustainable means of reducing running costs would be most welcome. A study on adoption of renewable energy technologies (RET) was conducted in Osogbo and Olorunda Local Government Areas of Osun State, Nigeria. Data were obtained from registered hotels in the two local government areas through structured questionnaires. Results were presented descriptively. Knowledge and awareness about RET were high among the managers of the hotels with 82.5%. Solar energy technology was the most popular among the respondents with 65.0%, while radio and internet constituted the highest sources of knowledge and awareness with 30.0% and 22.5% respectively. Among the hotels, 30.0% have adopted RET with the level of adoption stated to be moderate and low with 41.7% respectively. Solar energy technology was the most RET adopted with 83.3% of respondents. Among the hotels that have not adopted RET, 92.9% were willing to adopt RET, with all of them (100%) willing to adopt solar energy. However, 7.1% of those currently not adopting RET had previously adopted solar energy technology. Cost of maintenance of the technology, lack of expertise in maintenance and lack of spare parts were ranked first, second and third respectively as reasons for discontinuance of adoption of the technology.  For the hotels that have adopted RET, appreciable savings (15%) on cost of running was made, encouraging the provision of gym and outdoor recreational facilities, thereby leading to physical wellness of their customers. There is need for major policy shift by government in favour of solar energy technology and adoption. This policy should not be on awareness alone, but also in the provision of solar energy backbones and infrastructures, training and capacity building in installation, equipment parts and maintenance of the technology in order to increase and sustain adoption in tourism sector.

Significance Once completed, the Noor project will be the largest solar energy facility in the world, producing 580 MW. The expansion of renewable energy in Morocco is essential to reducing the country's growing dependence on imported energy. Impacts Successful expansion of renewable energy technologies will lead Morocco to re-evaluate coal import growth and its need for imported gas. If Morocco's renewables succeed, this would also demonstrate a low carbon pathway for North African states based on domestic industry. In the longer term, it is likely to revive European interest in potential electricity imports from North Africa's solar resources.

Economic Trends

Desalination is becoming a practical option to meet water demand in an increasing number of locations that are facing water scarcity. Currently, more than 150 countries in the world are already using desalination technologies, which account for about one percent of the world’s drinking water. Although for specific regions, desalination is the only feasible solution to close the supply–demand gap (for example the production of desalinated seawater in the Middle East is predicted to rise almost fourteen-fold by 2040), the sustainability of desalination systems is still remarkably under question. This review aims first to investigate the technical and economic trends and environmental and social aspects of desalination systems and then, in the second stage, to give an overview of the role of renewable energy technologies in the sustainability of the future water systems with an increasing share of desalination.

Forecasting the microeconomics of electricity will turn into a challenging process when electricity is produced through renewable energy technologies (RET). These technologies are mainly sunlight-based photovoltaic (PV), wind power, and tidal resources, which vigorously rely upon ecological conditions. For a reliable and livable energy supply to the electricity grid from renewable means, electrical energy storage technologies can play an important role while considering the weather effects in order to provide immaculate, safe, and continuous energy throughout the generation period. Energy storage technologies (ESTs) charge themselves during the low power demand period and discharge when the demand of electricity increases in such a way that they act as a catalyst to provide energy boost to the power grid. In this paper, we presented and discussed the renewable ESTs for each type with respect to their operational mechanism. In this regard, the renewable energy scenarios of Pakistan and Turkey are first discussed in detail by analyzing the actual potential of each renewable energy resource in both the countries. Then, policy for the EST utilization for both the countries is recommended in order to secure sustainable and reliable energy provision.
