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.

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.

As many programs of scientific and technical cooperation of various fields are being successfully implemented between Ukraine and the EU, the author has set the goal of intensifying relations between Ukraine and Chile in the field of green energy. The cooperation Ukraine has had with the EU serves as an example of future cooperation between Ukraine and Chile. The text explores Chile’s experience in the field of green energy and, through the comparative example of such cooperation between Ukraine and the EU countries, shows that such interaction is a worthwhile endeavor. Based on an analysis of research materials, one of the priority areas of scientific and technical cooperation is the use of non-traditional renewable energy technologies. In Ukraine, and the EU, as well as Chile, there are objective factors (natural, resources, socio-economic, environmental- technological) that concern their development. It is interesting to note Ukraine’s scientific experience and implementation of these technologies and the organizational and economic support of them as priorities in the context of national and regional policy. All aspects of international scientific and technical cooperation, including through the exchange of intellectual products, make it possible to increase the effectiveness of forms of state support, the innovation, production and business activities of Ukraine and the corresponding development of producers and consumers' motivation towards using non-conventional forms of renewable energy technology.

The rural electrification is the most needed pill for equitable economic and environmental development of Nepal. However, it comes with great challenges. The cost involved for grid extension, availability of power in grid and pre-condition required for alternate energy options for affordable rural energy supply significantly hinders the process of rural electrification. The low-head Pico-hydro is a promising technology which has positioned itself in a special niche of renewable energy technologies and is very important to address the problems Nepal is currently facing.DOI: http://dx.doi.org/10.3126/hn.v11i0.7166 Hydro Nepal Vol.11 2011 pp.64-66

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.

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.

<p>The research presented here is based on an extensive data set of five distinct nationally representative surveys in Austria sampling an average of 1.008 respondents per year. The surveys ran from 2015 to 2019 and were designed to measure respondents’ perceptions and attitudes towards various renewable energy-related issues, including perceptions of and attitudes towards electric vehicles and photovoltaic panels for private consumers but also renewable energy technologies in general and renewable energy production sites, specifically wind turbines, large-scale photovoltaic power plants and small-scale hydropower. Particular attention was paid to the question of local acceptance, or better, support for infrastructure in respondents’ local community. The data presented will thus offer a variety of perspectives. Firstly, longitudinal trends in the acceptance of small-scale hydropower will indicate the relative development of small-scale hydropower in terms of both regional differences but equally with respect to the two other surveyed renewable energy technologies. Comparisons on an aggregate level also offer an in depth and robust multiple regression analysis of the various predictors of social acceptance. Again, comparing these results to the results for both wind and photovoltaic energy technology. From an applied perspective, results are then discussed with respect to their implications for future renewable energy technology scenarios with respect to social acceptance and the role small-scale hydro power can play in these. Equally the rather novel scholarly effort to investigate social acceptance of small-scale hydropower and the potential for comparisons with more extensively studied renewable energy technology forms will offer an interesting ground for debate among academics and practitioners.</p>
