The study was carried out among Ilese-Ijebu residents southwestern Nigeria, to assess their perceived health and environmental problems associated with different sources of household energy use for cooking, then their perception and acceptability of adopting other alternative source of energy (biogas). A focused group discussion and self-structured questionnaire administration methodologies were adopted to elicit information on their current energy sources and adoption for alternative energy source (biogas). The researchers randomly selected twenty five (25) households to include the total sample size of one hundred (100) and organized an interactive session on the subject matter, during which three prepared forms were given out to the participants to filled their demographics characteristics, sources of energy for household cooking with associated health and environmental problems and perception and acceptability of biogas, descriptive statistics and likert scale technique were used to analyze the results obtained. The results of the analysis showed that, the respondents do make use of more than one source of energy for cooking, kerosene stoves (95), firewood (63), charcoal stove(32), while lesser people made use of liquefied gas (12) and electricity (5). Average numbers of respondents 50-60 are aware of associated health and environmental problems with firewood and charcoal, but not ready to use electricity and liquefied gas because of bills and fire hazards when the energy sources is  not properly handled. However, the likert scale results of the positive score of 227 and the negative score of 598 on the acceptability of use of biogas for domestic cooking indicating that, presently, the residents are not ready to adopt the biogas as the alternative energy. Therefore, there is need to organize massive awareness campaign, health education talks among the residents on the effect of air pollution associated with household energy sources and consumption, health and financial benefits of adopting other alternative clean energy source.

The supply of electrical energy in Tarakan City, North Kalimantan, still relies on diesel power which uses a limited number of petroleum energy sources. There is a need for research related to renewable energy sources that have the potential to become alternative energy for the people of Tarakan City. Water is an energy source that has great potential to generate electricity. The energy source that should be taken into account is micro-hydro which can be used as a Micro-hydro Power Plant (PLTMH). A survey of micro-hydro sources in Tarakan City, precisely in the Karungan area, East Mamburungan Village, has been carried out with the direct measurement method of water discharge and the relationship with the power generated. The result shows the water source has a discharge 0.00034 m3/ s, the water velocity of 0.035 m/s and generates power only up to 1.1 watts. Based on the power obtained, the water source in this place cannot be used as a source of micro-hydro energy, but has the potential as a source of pico-hydro energy.

In the recent attempts to stimulate alternative energy sources for heating and cooling of buildings, emphasise has been put on utilisation of the ambient energy from ground source heat pump systems (GSHPs) and other renewable energy sources. Exploitation of renewable energy sources and particularly ground heat in buildings can significantly contribute towards reducing dependency on fossil fuels. The study was carried out at the Energy Research Institute (ERI), between September 2016 and November 2017. This paper highlights the potential energy saving that could be achieved through use of ground energy source. The main concept of this technology is that it uses the lower temperature of the ground (approximately <32°C), which remains relatively stable throughout the year, to provide space heating, cooling and domestic hot water inside the building area. The purpose of this study, however, is to examine the means of reducing of energy consumption in buildings, identifying GSHPs as an environmental friendly technology able to provide efficient utilisation of energy in the buildings sector, promoting the use of GSHPs applications as an optimum means of heating and cooling, and presenting typical applications and recent advances of the DX GSHPs. It is concluded that the direct expansion of GSHP are extendable to more comprehensive applications combined with the ground heat exchanger in foundation piles and the seasonal thermal energy storage from solar thermal collectors. This study highlights the energy problem and the possible saving that can be achieved through the use of the GSHP systems. This article discusses the principle of the ground source energy, varieties of GSHPs, and various developments.

Purpose For India, with its low agricultural productivity and huge population, land acquisition has always been a serious policy challenge in the installation of land-intensive power projects. India has experienced a large number of projects getting stalled because of land conflict. Yet, there is a paucity of literature pertinent to India that tries to estimate future land requirements taking into consideration of land occupation metric. Design/methodology/approach In the present study, the dynamic land transformation and land occupation metrics of nine energy sources, both conventional and renewable, are estimated to further determine the magnitude of land requirement that India needs to prepare itself to fulfil its Intended Nationally Determined Contribution (INDC) commitments. This is illustrated through two different scenarios of energy requirement growth rates, namely, conservative and advanced. Findings This analysis suggests that, while nuclear energy entails the lowest dynamic land transformation when land occupation metric is taken into account, waste to energy source possesses least land requirement, followed by coal-fired source. Hydro energy source has highest requirement both in terms of dynamic land transformation and land occupation. It is also seen that land requirement will be 96% and 120% more in INDC scenario than business as usual (i.e. if India continues with its current share of renewables in its energy portfolio in 2030) considering a conservative and an advanced growth rate, respectively. Research limitations/implications Some policy recommendations are provided that may aid policymakers to better address the trade-off between clean energy and land and incorporate it into policy planning. This study has not been able to consider future technical efficiency improvement possibilities for all energy sources, which can be incorporated in the proposed framework for further insight. Originality/value This paper provides a framework for estimation of future land requirement to fulfil India’s INDC energy plans which is not available in existing literature. The authors confirm that this manuscript is an original work.
