The paper uses a range of sustainability-measuring indicators to define and measure sustainable energy in a rural context. The use of fuel wood and charcoal in rural areas has consequences on the environment and human health and ultimately, climate change. Fuel wood and charcoal consumption for example pose threats in through carbon emissions. Though Ghana and most African countries are not heavy carbon emitters, it is important to recognize that fuel wood and charcoal are major sources of residential and industrial energy resource. From the study, it was estimated that household and industrial/commercial fuel wood and charcoal consumption, emitted 24,171 tCO2/year and the net carbon capture was about 112billion tCO2/year. The balance between carbon emitted and capture provides an indication of more room for carbon sequestration in the area and its environs; however high growth in fuel consumption coupled with increasing forest reduction and water evaporation (refer to section 4.6.3 on data on evaporation) presents a case for concern over the years.

Access to modern energy services is one of the pre-requisites to improved livelihood, yet the poor, particularly in developing countries, remain tied to unhealthy and inefficient traditional fuels. Renewable energy technologies are increasingly popular energy supply alternatives to fossil-based fuels in many countries. This study presents sustainable energy system implementation options for increasing energy access in developing countries, with special emphasis on Sub-Saharan Africa. A feasibility case study and various implementation options are presented for possible deployment of these systems. Hybrid optimization of multiple energy resources software was used to simulate and validate the proposed hybrid system design and performance. The simulation results indicate that hybrid systems would be feasible options for distributed generation of electric power for remote locations and areas not connected to the electricity grid. Such a hybrid energy system, through providing modern energy services, gives promise to free-up rural communities to engage in productive activities. The opportunity to power or facilitate productive activities such as agro-processing, fabrication and services can potentially reduce poverty.

A study was conducted in the rural communities of the Giyani district in Limpopo Province, with the aim of identifying types of energy resources used and the patterns of utilization of such energy sources. Surveys were conducted in three villages and semi-structured questionnaires were used to interview 20 randomly selected households per village. Focus group discussions were also held in each of the surveyed villages. Data obtained in all surveyed villages showed that fuel wood is the main source of energy for cooking and heating while paraffin and candles are mainly used for lighting. Wood in these villages is very scarce and communities spend 5 to 6 hours per trip collecting fuel wood. Women using the loadhead method of carrying wood and occasionally wheelbarrows are the main source of labour used in collecting fuel wood. The paper concludes that there is a need to promote sustainable energy resources and technologies such as the use of improved wood and charcoal stoves. Furthermore, the paper recommends the promotion of solar photovoltaic (PV) systems, which have a potential of being adopted in the area. It is also argued that policies which enhance integrated rural development and promote sustainable energy utilization in rural communities need to be put in place and implemented.

Living cells naturally maintain a variety of metabolic reactions via energy conversion mechanisms that are coupled to proton transfer across cell membranes, thereby producing energy-rich compounds. Until now, researchers have been unable to maintain continuous biochemical reactions in artificially engineered cells, mainly due to the lack of mechanisms that generate energy-rich resources, such as adenosine triphosphate (ATP) and reduced nicotinamide adenine dinucleotide (NADH). If these metabolic activities in artificial cells are to be sustained, reliable energy transduction strategies must be realized. In this perspective, this article discusses the development of an artificially engineered cell containing a sustainable energy conversion process.
