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.

The Impact

Our study concentrates on the impact of public research and development (R&D) as solar PV market matures. This paper tried to distinguish the concepts of market maturity and technology maturity and to approach them measurably. Considering the concept of cost reduction rate and number of patent change rate, we estimates maturity indicator respectively. Next, we estimate how market and technology maturity interact with public R&D. Finally, we examine whether the R&D effect varies depending on market maturity. This study suggests the implications of the R&D policy of renewable energy technologies at various maturity levels by making the concept of market maturity which is commonly used and measuring the R&D effect according to market maturity.

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.

Development Goals

The European Union (EU) is committed to tackling the issue of climate change, which poses serious risks to the global environment and human well-being. Supporting renewable energy is a key policy direction for the EU to lower its contributions to climate change. However, renewable energy technologies have diverse effects on the environment and on society. These effects can be considered a complex system of interacting elements and are challenging to assess. Conceptual models are a way of synthesizing this information to obtain an overview of the system and essential insights. We present the results of an activity to assess the impacts of EU renewable energy policies on overseas biodiversity and the United Nations (UN) Sustainable Development Goals (SDGs). This was carried out as part of the EKLIPSE (EKLIPSE (Establishing a European Knowledge and Learning Mechanism to Improve the Policy-Science-Society Interface on Biodiversity and Ecosystem Services) mechanism to synthesise environmental knowledge in response to specific requests by decision-makers at the European level. We carried out a participatory process to collate expert knowledge into a conceptual model using a Fuzzy Cognitive Mapping Approach (Özesmi and Özesmi 2004), with the Mental Modeler software for mapping (Gray et al. 2013). The participants were guided to connect significant EU policies associated with renewable energy, the technologies they support, and known impacts of these technologies on biodiversity and the SDGs, drawing on a preliminary review of the literature. The individual models obtained were integrated into a single model (see Suppl. material 1 for images). This was then subject to network analysis, which reveals the collective effects of different renewable energy technologies (RETs) on the wider socioecological system. Our findings highlight that RETs have complex and at times disparate effects on biodiversity and the SDGs, acting through a variety of mediating processes. They benefit the SDGs on balance, particularly climate-related SDGs. Mitigation of biodiversity impacts remains a concern, and processes such as habitat change were found to be influential here. Our results suggest that policymakers must focus on implementing appropriate environmental impact assessments, guided by these mediating processes. This would minimize any negative environmental impacts of RETs, while maximizing the benefits.
