Currently, renewable energy development is emphasized for sustainable development goals accomplishment and the better realization of sustainable development globally. Tanzania, like other developing countries, is striving to adopt different ways of ensuring affordable and accessible energy supply to its socioeconomic and political sectors to achieve renewable energy development. To secure affordable and accessible energy in the country, renewable energy is termed as an alternative energy source because of it is environmentally friendly. If renewable energy is produced and utilized in a modern and sustainable manner, it will help to eliminate energy problems in Tanzania. Thus, this study aims to review the current potential renewable energy for the achievement of sustainable development in Tanzania. Moreover, challenges of renewable energy development are examined.

“…Production of ethanol from various sources, including algae, has certain limitations [63]. Efficient ethanol production from algae completely depends on their growth, accumulation of biomass levels, types of sugars in the feedstock and process of fermentation, which in turn depend on the species and various physicochemical conditions [64].…”

Overuse of non-renewable fossil fuels due to the population explosion urges us to focus on renewable fuels such as bioethanol. It is a well-known fact that ethanol is useful as a blending product with common fuels such as petrol and diesel. This reduces the cost besides bringing down environmental pollution. Apart from chemical methods, bioethanol is generated from photosynthetic plants including algae, plant-based products, microbial organisms and their waste. Specifically, the production of ethanol from microalgal sources has been an attractive method in recent days. The reason behind using microalgal species is their simple structure with photosynthetic ability. In contrast, certain algal species often go disused in some regions. Hence, the production of ethanol from algal sources is one of the best waste management practices. Moreover, it is easy to improve the biomass in microalgal species by altering the physicochemical conditions such as light, pH, temperature, external supply of nutrients, vitamins, nano-sized particles, gene alterations etc., which will enhance ethanol production. In this review, the methods used for ethanol production are discussed. In addition, the factors involved in algal growth and ethanol production are emphasized. Overall, this review focuses on ethanol production from various algal species. This information will be useful for industrial-level production of ethanol and future renewable energy research.

“…The share of hydro will increase from around 24% in 2015 to 40% by 2030 and then decrease to 25% in 2040. The share of hydro and geothermal are limited due to potential constraint of 4700 MW and 650 MW respectively despite their low operating cost advantages (Dincer, 2000;Kihwele et al, 2012;Kusekwa, 2013). Power generation is expected to almost triple by 2025.…”

Modelling of energy demand and supply patterns in Tanzania

Energy is an important element in realizing the interrelated socio-economic development of countries. In an attempt to develop long term energy demand and supply patterns that would enable the country meet her growing energy demand sustainably using the current and future available energy resources, a study of its own kind was carried out. The analysis of the influential indicators in the determination of energy demand based on the selected socio-economic and environment indicators preceded the study. Artificial neural network-multilayer perceptron (ANN-MLP), multiple linear regression (MLR), and support vector machine for regression (SVR) techniques were employed in the analysis. The findings depicts a strong relationship between energy indicators and energy demand for Tanzania. The energy indicators model showed greater accuracy in the prediction of energy demand as compared to economic and environment indicators models. ANN-MLP, MLR and SVR techniques reached satisfactory prediction results though ANN-MLP produced the most accurate predictions. The long-term energy demand simulation for a study period 2010-2040 was done using the Model for Analysis of Energy Demand (MAED). The simulation involved case study scenarios to mimic possible future long-term energy demand based on socio-economic and technological development. Simulated results suggest an exponential growth of the total final energy demand with electricity demand shift from household dominance towards industry and service sectors describing changes in the lifestyles. Nevertheless, the electricity demand growth rate has been shown to be greater than that of energy demand describing more mechanisation in the industry and service sectors. Final energy demands per capita shows an increasing tendency while there is a decrease in energy intensity suggesting energy efficient measures. Long-term energisation plan was achieved through a bottom-up modelling approach using Model for Energy Supply Strategy Alternatives and their General Environmental Impacts (MESSAGE). Least-cost results showed dominance of hydro, coal, geothermal and natural gas as possible supply options for future electricity generation. Though these energy resources are locally available and give least-cost advantages, their combinations is heavily skewed to the non-environmental friendly resources. Optimised results indicate, without interventions in promoting renewable energy, its influence in power generation will remain insignificant and therefore recommends policies ii formulations to ensure significant contribution. Finally, the results have established that it is feasible to have a sustainable and economical supply of energy for Tanzania that will meet her energy demand and ensure an optimized option for short, medium and long term energisation plans using currently available energy resources.
