Summary: This study analyzed the development of renewable energy policies in China and examined the impacts of different types of policies on provincial renewable energy development. The results showed that technology development policies have a positive effect on renewable energy, while market management policies may inhibit its development in provinces with abundant resources. Comprehensive planning policies and support policies such as finance and tax had no significant impact on renewable energy development. Therefore, the Chinese government needs to strengthen the control of market management policies and enhance the execution and supervision of planning management in provinces with limited resources.

Summary: The EU aims to be a global leader in renewable energy, but the technological development in the sector is hindered by the "valley of death", where promising technologies are trapped due to lack of cost competitiveness. This paper suggests policy solutions to support the EU renewable energy industry, including increased public funding, improved synergies between funding programs, and introduction of an EU risk insurance and guarantee fund to boost deployment and commercialization of new technologies.

Summary: Understanding the effectiveness of government policies in promoting renewable energy technology innovation is crucial for global energy transition. This study develops a patent quality index for renewable energy technology, incorporating time change factors to better capture technological innovation. By categorizing policies based on regulation intensity and technological characteristics, and using a sysGMM model, the study evaluates the policy effectiveness in enhancing technology patent quality. The analysis highlights the heterogeneous effects of different policies on diverse energy technology types and regions, with economic incentive and guiding demonstrative policies showing greater improvement in patent quality. The findings suggest that local governments should carefully consider the use of high regulatory strategies, and policy design should account for policy effects, technical, and regional heterogeneity.

Summary: The study finds that fossil fuel utilization has a significant positive impact on environmental degradation in the selected OPEC countries, while the negative impact of renewable energy utilization and urbanization on carbon dioxide emissions is insignificant in both the short and long run. The current energy transition policy of OPEC states is not sufficient for environmental sustainability, and the Environmental Kuznets Curve is not valid in the panel of OPEC countries. The research also shows a uni-directional causality from income level to renewable energy consumption, and urbanization strongly Granger causes fossil fuel use and CO2 emissions among the countries.

Summary: South Korea has heavily invested in marine and ocean technologies to achieve renewable energy goals. However, there is a lack of understanding regarding the environmental benefits of innovation in marine energy generation. This study finds that there is a long-term relationship between international collaboration, GDP, commercial policy, renewable energy use, marine energy technologies, and CO2 emissions in South Korea. Increasing marine energy technologies assists in generating low-carbon renewable energy and improving environmental quality.

Summary: This study examines the effectiveness of environmental policy in reducing ecological footprint while considering the roles of renewable energy and innovation. Employing a cross-sectional autoregressive distributed lags to analyze panel data of 29 OECD countries from 1990 to 2020, the study finds that environmental policy significantly reduces ecological footprint among OECD countries, with its efficacy contingent upon bio-capacity surplus/deficit and the level of industrialization. The study also reveals that renewable energy has a favourable impact on ecological footprint reduction, while innovation improves the environmental quality of OECD countries. However, population density and industrialization were found to decrease and increase ecological footprint, respectively. The study's findings demonstrate bi-directional causation between ecological footprint and all variables except for economic growth, and are robust under the conditions of short-run heterogeneity, long-run homogeneity, and cross-sectional dependence.

Summary: Countries are utilizing local municipalities as a pillar for the development of renewable energy systems, requiring them to expand innovation policies to support the transition towards renewable energies. The triple helix model plays an important role in establishing local RES policies, with government and the private sector being crucial in all three policy criteria. Universities contribute primarily to knowledge generation and transfer in the context of RES innovation.

Summary: This study examines the impact of government ideology on renewable energy consumption in EU member countries. The results suggest that an increase in the power of right-wing parties is associated with a decrease in renewable energy consumption, while an increase in the power of left-wing or center-wing parties is associated with an increase in renewable energy consumption. Green parties and Christian democratic parties play a significant role in driving renewable energy consumption.

Summary: The aim of this research is to create a theoretical framework for a local energy innovation system based on renewable energy sources. Four types of clusters were outlined based on energy-generation capacity and socio-economic factors, revealing diverse features in terms of energy-generation capacity and innovation abilities in areas of Poland. For each type of area, energy potentials combined with innovation abilities were established. The concept of the regional innovation system has been adjusted to support areas with insufficient energy and innovation capacities in their development of local energy sovereignty. The results of the research can aid in the development of national and regional energy policies focused on the specificity and capacity of energy generation and innovation of each area.

Summary: Due to the increasing emission of greenhouse gases and global warming, the development of renewable energy has become crucial. Policies supporting renewable energy play a significant role in increasing the deployment of renewable energy technologies, regardless of a country's group. Developed oil countries have more capacity to support renewable energy projects than oil developing countries due to their higher efficiency in renewable energy policy.

Summary: Complementary renewable technologies can help balance the intermittency of solar and wind generation. Previous research shows that environmental policies targeting renewable energy can drive innovation in solar PV and wind technology. This study examines the impact of renewable policies on innovation in complementary renewable technology, including combustion, transmission and distribution, and enabling technologies. The findings suggest that policies solely targeting renewable energy may not incentivize innovation in complementary fields and that policymakers need to go beyond these policies to drive innovation in these areas.
