Analysis of the dilemmas of solar energy application for Taiwan building with Fuzzy AHP approach

Abstract

Energy is a key indicator to show economic development and improved quality of life in countries. Thus, it is also an essential factor to achieve sustainable development. Therefore, renewable energy can play a significant role in satisfying the future energy need and supply. Taiwan is highly vulnerable in energy security, but geographic conditions for the development of solar energy applications have created a considerable advantage. However, the total installed solar energy capacity is far less than might be expected. Consequently, this study proceeds to explore the dilemmas that affect solar energy application concerning Taiwan buildings. Through the evaluation decision-making system model and expert decision-making groups giving fuzzy evaluation values and feedback, access the relative importance of each dilemma factors by using Fuzzy AHP. The study found the critical factor and propose strategies for solar energy development in the future to improve the quality and quantity of renewable energy applications and competitiveness of national energy. This research, in addition to providing references to relevant environmental energy systems for deployment and technological R&D, it also provides developing and underdeveloped countries access to applications of solar energy technology assessment and forecasts for the future.
