Energy Efficiency for Small and Medium Enterprises
A general misconception among industries, small or large, in developed as well as developing countries, is that taking care of the environment, by using clean technologies and by saving energy, is a cost-incurring activity. This conviction leads to a poor attention to environmental considerations and therefore high losses in raw materials, energy and finances. Energy Efficiency for Small and Medium Enterprises forms part of the Energy and Environment Technology Source Books series. The book shows that the improvement of product efficiency can be in harmony with financial gains. In particular, it encourages support for women entrepreneurs to get involved with the technical aspects of the production process. Above all, Energy Efficiency for Small and Medium Enterprises aims to provide basic information on energy saving options for those involved with the economic empowerment of micro entrepreneurs.
