In transition to a low-carbon economy, the adoption of renewable energy (RE) technologies by energy investors, power utilities and energy consumers is critical. In developing countries like Kenya with a high rate of urbanization, this transition requires urban and rural residents’ proactive responses to using renewable energy sources. In this regard, a better understanding of residents’ perceptions about renewable energy investment, RE sources availability, climate change, environmental conservation and other factors can lead to more efficient and sustainable implementation of renewable energy policies. This study investigates the role Kenya’s household energy consumers in urban and rural areas can play in adopting renewable energy technologies. To achieve this, a questionnaire survey was administered among 250 household consumers in Nairobi County, Makueni County, and Uasin Gishu County. Our survey analysis shows that about 84% of the respondents were interested in adopting renewable energy for their entire energy consumption mostly because of solving frequent power outages and high energy cost from the grid system. This perception did not have any correlations with income levels or any other socio-economic factors we identified. Furthermore, about 72% of the respondents showed their interests in producing and selling renewable energy to the national or local grids if government subsidies were readily available. Rural residents showed strong interests in adopting renewable energy technologies, especially solar PV solutions. However, the main impediment to their investment in renewable energy was the high cost of equipment (49%) and the intermittent nature of renewable energy (27%) resources.

Primary Energy Supply

The study analyzes the economics of renewable energy sources into electricity generation in Tanzania. Business as usual (BAU) scenario and renewable energy (RE) scenario which enforce a mandatory penetration of renewable energy sources shares into electricity generations were analyzed. The results show total investment cost for the BAU scenario is much lower as compared to RE scenario while operating and maintenance variable costs are higher in BAU scenario. Primary energy supply in BAU scenario is higher tied with less investment costs as compared to RE scenario. Furthermore, the share of renewable energy sources in BAU scenario is insignificant as compared to RE scenario due to mandatory penetration policy imposed. Analysis concludes that there are much higher investments costs in RE scenario accompanied with less operating and variable costs and lower primary energy supply. Sensitivity analysis carried out suggests that regardless of changes in investments cost of coal and CCGT power plants, the penetration of renewable energy technologies was still insignificant. Notwithstanding the weaknesses of renewable energy technologies in terms of the associated higher investments costs, an interesting result is that it is possible to meet future electricity demand based on domestic resources including renewables.

Renewable energy can contribute to adaptation to climate change, mitigation and development and may play an important role in resilient development ambition of Nepal. It has been emphasized in Nepal's Nationally Determined Contribution (NDC) and climate change policy but its potential impact on SDGs era has not been fully explored and implemented. The study used employed energy system modelling by using optimization software, reviewed literature and interacted with various experts. It has been found that renewable energy technologies (RETs) provide socio-economic and environmental benefits to people that contribute to adopting and ensuring a better adaptation to climate change based on the local context. They contribute to adaptation processes by contributing to reducing the vulnerability of people, improving adaptive capacity, and minimizing climate change risk in line with SDG 7. But these are not without challenges either. Financial, technical, institutional, policy and legal issues are major challenges to promote RETs. This study shows that theoretically altogether 4.45 million tons of CO2e of the GHG emission can be mitigated per year if all the remaining technical potential of deploying seven major RETs consisting of biogas, improved water mill, stand-alone micro-hydro plants, mini-grid micro-hydro plants, solar PV home systems, mud-ICS and metal-ICS were installed after 2012. Considering the average annual installation of these RETs, altogether 30.71 million tons of CO2e can be mitigated between the periods of 2013 to 2030 at an annual additional installation equal to average installation done in recent past three years. The initial technology investment required for implementing the above mentioned RETs ranges from NRs 97 to NRs 23,247 per ton of CO2e mitigation. This indicates that though a moderate level of the initial investment is required for promoting RETs, the GHG mitigation potential seems to be quite promising. There is no liberty of inaction, so RETs can be a good case for a triple win strategy to address mitigation – adaptation – development nexus for climate compatible development in Nepal.

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.

Key Indicators

In recent years, renewable energy sources have played an increasingly important role in potential energy production. The integration of renewable energy technologies into existing national energy system has therefore become a major challenge for many countries. Due to the importance of this matter, this paper deals with the comprehensive analysis for implementation of a power plant on biomass (straw). The analysis is conducted regarding several key indicators: availability of biomass, regulation, reduction of greenhouse gas emissions, location, land use, electricity price and social impacts. The analysis also includes favorable price for electricity produced from biomass relevant to national feed in tariffs. In order to demonstrate all above mentioned indicators, the region in Serbia (Province of Vojvodina) with significant potential in biomass, especially in straw, is selected. The results of the analysis are validated trough environmental and social aspects. Special attention is given to identifying risks for this application.

Renewable Energy Generation

Marine renewable energy has the potential to solve both the energy-security and coastal-protection problems affecting coastal societies. In this article, the potential benefits arising from the combination of marine renewable energy technologies with infrastructural needs for coastal protection and other local needs are analysed. Classifications of technologies are developed to inform future coastal planning. Explanations of the resources and technologies are presented in layperson’s term. The threat of coastal inundation under climate-change scenarios is a major global issue. The investment in new infrastructure demanded by cities, ports and communities at risk of inundation could very substantially reduce the levelised cost of electricity from renewable sources, provided the infrastructure is designed with the dual purpose of power generation and coastal protection. Correspondingly, the sale of electricity from such infrastructure could defray the long-term cost of installing coastal protection. Furthermore, many marine renewable energy technologies provide a platform on which other forms of renewable energy generation could be mounted. It is noted that the complex geophysical and engineering issues arising from this opportunity must be assessed considering socio-economic factors.
