人類大量使用化石燃料是造成全球暖化加速的原因之一。為了探討可再生能源發展對減緩地球暖化之可能貢獻，本研究就學理上檢視低碳經濟發展模式與架構，以世界數個國家可再生能源為分析之對象，且進一步以德、日、台、中數個國家可再生能源發展與低碳經濟政策進行分析，並以計量方法進行追蹤資料實證分析所得、化石燃料、可再生能源、以及碳排放之間的因果關係。據以提供政策建議，釐清經濟成長、節能減碳政策、可再生能源的發展、可再生能源與不可再生能源的消費之間的Granger因果關聯性。以可再生能源發展為主，構成之低碳排生產型態對經濟發展的影響仍未有顯著因果關係。本研究證實，依據雁行理論，期望透過可再生能源發展達成低碳排之政策目標。
Global warming speeding up is caused by burning of fossil fuel. To research the possible contribution of the renewable energy development to slow down global warming, this study analyzed renewable energy development with the theories related to the model of low carbon economy and the structure of low carbon economy. This study analyzed the policy of low carbon economy and the renewable energy development for Germary, Japan, Taiwan, and China Space. With the econometric methods, this study analyzed the causality between income, fossil fuels, renewable energy, and carbon emissions. Unfortunately, results showed no significant causality between the development of renewable energy and income. This research suggests that following flying geese model to develop renewable energy can be further expected to reach the idea goal low CO2 emissions.
