Renewable energy investments in Poland: goals, socio-economic benefits, and development directions
Renewable energy sources (RES) will play a key role in the transition to clean energy. Financial and socio-economic benefits determine the investment management in these energy sources. This article aims to indicate current energy policy goals, present socio-economic benefits resulting from renewable energy investments, and review further development directions in Poland. The research was carried out using desk research, case studies, and literature review methods to provide a broader economic context for RES investments. The scope of the research included both the Polish and the European Union contexts. The authors examined the Polish objectives of investment in renewable energy contained in strategic, planning, and other legal documents compared to EU targets, reviewed possible investments in renewable energy, and indicated wind farms and photovoltaic investments as the most effective ones from the point of view of further development which aims to meet the EU’s goals by 2030. The authors also demonstrated a wide range of socio-economic benefits based on literature reviews, analysis of policy documents, and regulations regarding the energy sector, and examined a specific example of investment implementation and identified the ecosystem of beneficiaries and their benefits.
Examining Key Barriers and Relevant Promotion Strategies of Green Buildings Adoption in Tanzania
Green buildings (GBs) offer significant potential to address environmental challenges and support nations to meet their sustainable development goals. Numerous developed countries have prioritized green building technologies (GBTs) adoption in their construction industry, whilst other nations are still hampered by several issues that slow down the level of their adoption. To effectively promote the adoption of GBTs, it is crucial to identify the key barriers and to prioritize relevant promotion strategies suitable to be emphasized towards specific geographic locations. This study aims to examine the key barriers hindering the adoption of GBTs and recommend suitable strategies to promote GBT adoption in the context of Tanzania. A questionnaire survey was carried out with 61 experts (architects, engineers, urban planners, economists, and green technologists) from Tanzania working in the field related to green buildings. A ranking analysis technique was used to rank the barriers and relevant promotion strategies to be prioritized. Measures of descriptive statistics, including mean and standard deviation, were carried out to sort the barriers and promotion strategies in the order of their potentiality. A Spearman’s rank correlation test was conducted to verify the consistency of the mean scores and derived ranks, and cluster analysis was also performed to group factors that share similar characteristics into the same clusters. Unfamiliarity with GBTs; a lack of expertise or few professionals in the GB field; the presence of few successful demonstrative projects to convince clients; and a low promotion of GBTs together with limited user knowledge were noted as the most critical barriers hindering the adoption of GBTs in Tanzania. Cluster analysis shows that knowledge-related barriers are majorly hindering the adoption of GBTs in Tanzania. Thus, a multi-faceted approach of institutional interventions and broadening public awareness should majorly be taken into account simultaneously to enhance adoption rates. The analysis also revealed that the establishment of an institutional framework; educational programs for policymakers, developers, and contractors related to GB guidelines; providing awareness to clients through advertisements; and imposing mandatory regulations in shifting towards GBTs are the most relevant promotion strategies to widen the adoption of GBs. The findings of this study provide valuable insights to various stakeholders for policy development in the construction industry and the future implementation of GBs in Tanzania.
