Abstract
Small and medium-sized enterprises (SMEs) are crucial in every economy, comprising ninety-nine percent (99%) of
enterprises and providing about sixty percent (60%) of employment. They contribute about fifty percent (50%) of global gross
value addition and between sixteen percent (16%) to about eighty percent (80%) of gross domestic product (IEA, 2015).
Individual SMEs use small amounts of energy, but their collective energy demand is considerable. The International Energy
Agency (IEA) estimates SMEs to consume more than thirteen (13%) of total global energy demand i.e. about 74 exajoules (EJ).
Effective energy efficiency measures can save as much as 30% of consumption, namely 22 EJ, which is more than the energy
used by Japan and Korea per year (IEA, 2015). Therefore, the increase in energy efficiency offers a substantial value for
economies, societies and SMEs. This research looks at how SMEs in the Sunyani Municipality take seriously their energy
consumption and how energy management can help reduce energy cost through efficiency improvement and increase
profitability and growth of their businesses. The study was designed into two forms. Firstly, the energy use practices of the SMEs
were investigated. Secondly, the study applied energy auditing method to identify energy reduction strategies that can help
reduce the energy consumption of the SMEs. The results reveal that, majority of energy consumers in SMEs do not pay attention
to their energy consumption patterns as indicated by 92% of the respondents interviewed. The increase in energy consumption
among SMEs could be attributable to the increase in electricity bills. The energy audit identified energy conservation
opportunities that can help reduce energy usage in the various SMEs such as switching from CFL and T12 lamps to LED bulbs,
replacing old refrigerators, hair driers and industrial irons with more efficient ones, and replacing worn out equipment with high
energy efficient ones. The study recommends the use of public education in a paradigm shift from the use of old appliances to
new ones in order to save energy and cos
