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.

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.

Carbon Neutral

In this paper, a general methodology for designing carbon-neutral residential communities is presented. Both energy efficiency measures and renewable energy technologies are considered in the design approach. First, energy end-uses for the buildings within the community are optimized based on a set of cost-effective energy efficiency measures that are selected based on a life-cycle cost analysis. Then, renewable energy technologies are considered to meet the energy needs for the residential community and ensure carbon-neutrality on an annual basis. The methodology is applied to design optimal and carbon-neutral hybrid electrical generation systems for three Kuwaiti residential communities with different sizes and energy efficiency designs. For Kuwait, it is found that wind turbines can cost-effectively generate significant electricity to meet most of the energy needs for the residential communities and thus reducing the country's reliance on fuel-based power plants. Specifically, it is found that wind turbines can generate electricity at a cost of $0.068/kWh well below the current grid power production costs of $0.103/kWh. Moreover, the analysis indicates that concentrated solar power (CSP) can be utilized to achieve carbon-neutral residential communities but at a levelized energy cost of $0.13/kWh slightly lower than the current grid power generation and distribution costs of $0.133/kWh.

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.

The Impact

With the increasing concerns regarding fossil fuels and nuclear energy, greater attention is being placed on alternate renewable energy technologies (RETs) such as wind, solar, and bioenergy. However, implementation of modern RETs has become controversial, as adverse health effects are a major concern. Although local case studies have suggested a relationship between wind turbines and health, there is a gap in the scientific knowledge. Epidemiological studies with adequate data collection tools and analyses are needed, particularly in the Canadian context. We reviewed surveys used in relevant environmental health literature, created a data collection tool for use in populations exposed to wind turbines, and piloted the survey content and distribution method. Our pilot response rate was 25.5% (45/200). The mean age of survey respondents was 57.6 years (SD: 12.76) with 57% of the respondents being female; respondents were not significantly different than the target population with respect to age or sex. The survey and methods presented here can be used in future studies to assess the health impacts of renewable energy technologies.

AbstractThe progress towards climate neutrality and sustainable development of the national economy is increasingly challenging. At the European Union level, the target for renewable energy set by Directive 2018/2001 is at least 32 %. Industry is not only an essential part of the national economy but also a field of opportunity for increasing the share of renewable energy in the total final energy consumption balance of the country. The paper evaluates renewable energy technologies using a combination of AHP and TOPSIS methods using technical, economic, environmental, and social criteria. In order to indicate the needs, potential barriers, and position of enterprises on renewable energy, an enterprise survey is conducted. Both the survey and multi-criteria decision analysis ranks solar PV as the technology with the highest potential. The results of the survey overall show that enterprises are open to renewable energy technologies, especially if incentives such as financial support are available, for example, in the form of a grant.
