Recent movements for the decarbonization of the electricity sector have become a priority for many countries around the world and will inevitably lead to the sharp decline of fossil-fuel-based energy. Energy from fossil fuels is to be replaced by renewable energy sources (RES), although the transition will neither be cheap nor smooth. One sustainable and environmentally friendly alternative to fossil fuels and which will take a considerable share in the increasing supply of renewable energy resources is biofuels. There are various types of biofuels used in practice; however, biodiesels represent one of the most popular and widespread ones. This paper focuses as a case study on the byproducts of Jatropha curcas, a crop and a plant that is already used for biofuel production and which is subsequently employed in electricity generation in Jatropha curcas producing regions. This paper identifies the limitations and prospects of Jatropha curcas utilization. Also, Jatropha curcas is compared to other materials suitable for biomass generation. An economic analysis for a 2 MW biofuel powerplant was conducted incorporating various market-related risks. The study shows that at current prices, net profitability can be achieved using Jatropha curcas byproducts for producing electricity.

“…The thermal energy produced with biogas positively affect evaluation outcome. The RE policy incentives can attract investors for biogas and improve biogas plants' viability if the policy is amended and independent projects are allowed as a renewable plug-in (Govender et al, 2019). In Pakistan, the biogas power plant can be benefited from the economic conditions.…”

The extensive need for energy has become a global issue due to the enormous population growth and demand for electricity-based products. Energy crises are rapidly increasing, which have destructive impacts on the industry in Pakistan. Biogas technology adoption is a challenge in a developing country like Pakistan. The government sector has taken initial steps to eliminate the energy crisis and promoted biogas plants. The primary objective of this study is to explore the satisfied and unsatisfied ratio of farmers who have adopted biogas plants in the country. The sample size was identified through the snowball sampling method. A total of 51 biogas adopters participated in this study. The structured questionnaires were used to collect data through online interviews. The results indicate that 34% of biogas plant respondents were satisfied with their plant feedback. The partially satisfied respondents were 24%, whereas 42% showed unsatisfaction. More than half (58%) of the respondents expressed that biogas plants are in good working conditions; however, 42% of biogas users were unrestrained for several causes. The findings of this study indicate that major maintenance and day-to-day operations of biogas plants are expensive due to lack of skilled operators, untrained or partially trained owners, and unavailability of technicians. The results suggest that the government needs to plan a clear policy, technical support with skilled technicians to biogas plant owners, all through an integrated and coherent way.

“…Biogas produced from organic matter is increasingly becoming a renewable energy solution in relation to growing energy and organic waste concerns to mitigate the environmental and public health concerns of organic waste (Govender et al, 2019;Garcia and You, 2018). Compared to other renewables such as wind, solar and hydroelectric, Biogas offers end-user multifaceted benefits (Hakawati et al, 2017).…”

“…In addition to the above, for renewable energy systems, biogas has the second smallest life cycle emissions (LCE), with wind energy having the smallest LCE. Compared to conventional energy systems such as coal, gas, and oil, Biogas LCE is also more than 3 times smaller (Govender et al, 2019). Deducing from the aforementioned elucidation, it can be also noted that the inputs for biogas such as manure, crop residues, and food scraps are freely available and will always be available which makes it be a sustainable energy alternative at household level in rural areas.…”

This study examined Zimbabwe's energy access situation and suggests that Zimbabwe's energy access solution goes beyond providing biogas energy alone but needs addressing the root causes of Zimbabwe's inability to access renewable energy. The paper also challenges biogas fuel prospects and shortcomings. A mixed-method methodology has been used. Next, the qualitative data analysis was carried out using thematic analysis. The themes emerging from the findings include lack of knowledge about biogas power, difficulties in accessing start-up capital, and lack of resources needed. From a quantitative viewpoint, it was discovered that lack of adequate funds, high installation costs, lack of adequate data and negative attitudes to the community are some of the challenges that block biogas to be considered as renewable energy for the poor in rural Domboshava, Zimbabwe at household level. Based on the findings of the article, organizational consequences are explored, and recommendations are made for shortcomings and future directions for analysis. Broadly speaking, this study adds enormously new knowledge to the existing energy economics literature in Africa-a context that some scholars in developing countries still ignore most.
