The Importance of Using Solar Water Heater as an Alternative Eco-Friendly Technology in Global Market: Some Lessons of Experiences for Bangladesh Economy

Abstract

This research paper introduces alternative heating technology for Bangladesh in the form of solar water heater against conventional heating on the face of increasing demand for heating water. Solar water heater is that renewable technology which simply uses free sunlight to heat water. The main benefit of using this technology is that it is completely pollution free, unlike other nonrenewable sources. However, from an economic point of view, it might not be a short term solution but will be economically viable in the long term. This technology also has the potential to ensure future energy security by diverting the energy load from non-renewable to renewable. This research paper gives a comparative analysis on the use of solar water heaters among different countries and Bangladesh. It also incorporates some useful measures that have attributed to the development of this industry. In this regard, many developed countries such as China, India, South Africa, Brazil, and Barbados along with small country like Tunisia have set up a remarkable example by patronizing this industry. This research paper has analyzed the factors and measures adopted for this technology in those countries and investigated the viability of solar water heating in the perspective of Bangladesh. It also aims to make a contribution to our energy sector by promoting this renewable technology with the lessons learned from those countries.
