Abstract

Purpose

This study aims to present preliminary results from an integrated evaluation of electricity supply systems for rural areas using renewable energy technologies by means of a multi‐objective decision making method

Design/methodology/approach

Goal programming is applied to obtain the optimal system configuration meeting the electricity demand, based on the location's resource availability and taking diesel generation as the alternative of reference. The performance of the system is evaluated through four attributes: electricity generation costs, employment and two environmental impacts (CO2 emissions and land use). The model is designed for isolated rural area belonging to the non‐interconnected zones of Colombia.

Findings

Application of the method showed that biomass conversion technology has the highest potential and that renewable energy systems offer better performance than diesel generation. Reductions of more than 10 percent in unit electricity costs, land use rates and CO2 emissions can be achieved.

Research limitations/implications

Inclusion of additional attributes and sensitivity analysis are matters of future research.

Originality/value

The methodology used in this study is an alternative means to perform evaluation of electricity supply systems integrating several aspects of technology and which is flexible enough so as to enable the inclusion of a wider scope of interests towards energy access targets.

Abstract

This chapter provides a critical discussion of challenge-based learning (CBL) within future trends in higher education (HE). It explores how CBL may address challenges facing higher education institutions (HEIs) in response to these future trends by using a framework of common CBL characteristics. Clear recommendations for CBL practitioners to succeed in CBL implementation within the ever-changing HE landscape are presented. It complements previous chapters on CBL case studies by situating CBL in the broader HE space. A discussion on the interrelationships between these characteristics and predictions on the future integration of CBL in HE concludes this chapter. These macrolevel discussions of CBL will be of interest to government officials, managers, business stakeholders, teachers, policy advisors, and academic teachers. Insights on the future institutional impact of CBL, how it may improve business and academic collaborations, how it aligns with sustainability and transversal skills policies, and where CBL is situated in the post-COVID-19 landscape are discussed. Ultimately, it argues that CBL is part of a pedagogical toolkit to meet future trends in HE.
