The global demand for energy has been on the rise. Most of this demand has been satisfied through hydrocarbons. The exploration, exploitation and growing consumption of hydrocarbon have had great impact on the environment. At the rate energy demand is rising and the disappearance of cheap hydrocarbon, other sources of energy would have to come into the energy mix to meet this growing demand. Despite ready availability of energy being desirable and a key to economic progress, energy development has to be done in a way that ensures our environment can continue to exist and support life. As energy development is putting stress on the environment and the need to sustain the environment is putting constraints on conventional energy development, policy development and technological innovation especially towards the development of renewable energy have come to play a big role. This paper uses quantitative and qualitative approaches to show the roles of technological innovation and policy development in achieving a balance between the sustainability of the environment and meeting energy demands.

This article identifies the agenda of decoloniality as a call to seek solutions to Africa’s problems from within herself (Africa). This call has its hold in colonial and post-independent attempts by African Nationalists, writers, freedom fighters and philosophers to defend Africa’s cultural heritages, even against its underestimation by scholars of other climes of the world. It further argues that, though justice done to this quest would afford Africa to regain her existential humanism in a global setting, the defence of African cultural heritages has not yielded much-desired efforts due largely to methodological error. This article observed that African scholars often, in the attempt to free their intellectual outputs from European ethnocentric postulations, overbears the indigenous idea in the decolonial projects. This error is noted to be a consequence of the tendency to deify African worldviews and thought processes. Employing the conversational method of philosophising Chimakonam (2015, 2017a, 2017b, and 2018), this article attempts to interrogate the agenda for decolonisation and re-Africanisation. It argues for the idea of conversational decolonisation. This article concludes that a conversational decolonised process would, among other things, be appropriate for a scholarly response to colonial denigrations and underestimations of African cultures and traditions. It would also be a framework for achieving African self-definition in the modern world without compromising African identity.

With its envisioned benefits of increased productivity, enhanced decision making with digital-based tools, qualitative and efficient processes, improved life expectancy rate, etc., the Fourth Industrial Revolution (4IR) is a desideratum for contemporary society. The need to prioritize skills and knowledge needed for the participation of Africa in the 4IR thus becomes imperative. This paper argues for indigenous knowledge systems (IKS) as a possible approach to enhance African participation in the 4IR. Consequently, the paper examines the methodical perspectives that would be appropriate for framing African Indigenous Knowledge Systems (AIKS) as a tool for advancing science and technology. It argues for the process form of ideating IKS against the content forms implicit in the various views on IKS. It is concluded that the process form of ideating IKS – which essentially focuses on the critical analysis of the systematic formations and development of IKS – unearths the epistemological basis for scientific postulations and technological advancement in Africa.
