由於美國頁岩氣開採技術的突破，帶動全球能源的革命與轉變。頁岩氣主要具有低排碳、低成本與儲量高的優點，然其開採對環境的影響、前景是否被高估、各國的保守態度等風險仍需要進一步評估。美國頁岩氣出口目前受限於法規、設施與市場區隔等因素，短期內大量出口不易，然其對全球能源的間接影響已經造成。此外，在全球對溫室氣體減排的壓力下，頁岩氣的革命對再生能源的影響成為重要的課題。本研究評估頁岩氣對全球、美國與我國可能造成的影響與再生能源之發展，歸納短期內頁岩氣對我國再生能源發展影響有限，然長期恐延緩再生能源市電同價時程。我國在頁岩氣革命下，應以天然氣作為能源轉型的過渡能源，長期來說仍應積極推廣再生能源，積極投入再生能源相關技術的研發。

As the technology breakthrough of U.S. shale gas, it drives global energy revolution and change in recent years. The shale gas has the advantages of low carbon emissions, low cost and high reserves. However, it needs further evaluation on the development of shale gas for the impact on the environment, the overestimated prospects and the national conservative attitudes. The exports of U.S. shale gas are currently subject to regulations, facilities and market compartments, and therefore are not easy to be done in the short time. However, it still has the indirect effects on the global energy market. In addition, due to the pressure of global greenhouse gases emission, the shale gas revolution on the impact of renewable energy has become an important issue. This study focused on the possible impact of shale gas on global, U.S. and Taiwan’s renewable energy development, and the results for Taiwan are the limited impacts in the short-term and delaying the grid parity in the long-term. Under the shale gas revolution, the natural gas should be an import role for energy transition for our country, and it makes us have the time to promote renewable energy and actively involved in development of renewable energy related technologies in the long-term.
