Energy transitions are complex and involve interrelated changes in the socio-technical dimensions of society. One major barrier to renewable energy transitions is lock-in from the incumbent socio-technical regime. This study evaluates Energy Product–Service Systems (EPSS) as a renewable energy market mechanism. EPSS offer electricity service performance instead of energy products and appliances for household consumers. Through consumers buying the service, the provider company is enabled to choose, manage and control electrical appliances for best-matched service delivery. Given the heterogenous market players and future uncertainties, this study aims to identify the necessary conditions to achieve a sustainable renewable energy market. Simulation-Based Design for EPSS framework is implemented to assess various hypothetical market conditions’ impact on market efficiency in the short term and long term. The results reveal the specific market characteristics that have a higher chance of causing unexpected results. Ultimately, this paper demonstrates the advantage of implementing Simulation-Based Design for EPSS to design retail electricity markets for renewable energy under competing market mechanisms with heterogenous economic agents.

Agrivoltaic systems (AVS) offer a symbiotic strategy for co-location sustainable renewable energy and agricultural production. This is particularly important in densely populated developing and developed countries, where renewable energy development is becoming more important; however, profitable farmland must be preserved. As emphasized in the Food-Energy-Water (FEW) nexus, AVS advancements should not only focus on energy management, but also agronomic management (crop and water management). Thus, we critically review the important factors that influence the decision of energy management (solar PV architecture) and agronomic management in AV systems. The outcomes show that solar PV architecture and agronomic management advancements are reliant on (1) solar radiation qualities in term of light intensity and photosynthetically activate radiation (PAR), (2) AVS categories such as energy-centric, agricultural-centric, and agricultural-energy-centric, and (3) shareholder perspective (especially farmers). Next, several adjustments for crop selection and management are needed due to light limitation, microclimate condition beneath the solar structure, and solar structure constraints. More importantly, a systematic irrigation system is required to prevent damage to the solar panel structure. To summarize, AVS advancements should be carefully planned to ensure the goals of reducing reliance on non-renewable sources, mitigating global warming effects, and meeting the FEW initiatives.

Renewable energy has become the buzzword in the 21st century especially during the United Nations declarations of the Submit 21 in which world leaders renewed their efforts in achieving the seventeen sustainable development goals. One of the challenges of the developing world is achieving a reliable energy supply for industrialization and energy security. Thailand is one of the countries with the highest energy consumption within the ASEAN region and hence, several policies have been implemented to deploy a clean source of energy for both domestic and manufacturing purposes. However, there are many institutional factors that seem to impede this drive for a greener energy supply in the country. This study sought to investigate the institutional factors that support sustainable renewable energy policy development in the Thai context. The study selected 400 respondents from renewable energy producing companies in Bangkok and Ayutthaya using a survey instrument. The results were analyze using SPSS version 22.0 with multiple regression technique. The results showed that institutional variables such as stakeholder involvement, government R&D framework, regulatory procedures, and government subsidies had an influence on sustainable renewable policy development. The study recommends that future government policies should engage key stakeholders in the policy dialogue and implementation process.
