The Analysis of Economic Synergy for the Recycle Energy in Taiwan

[[abstract]]全世界在環境驟變及能源短缺的雙重議題下，興起節能減碳課題，而各國政府亦大量投入替代能源的研究及補助再生能源的政策，來降低溫室效應及促進產業的發展。由於目前再生能源(本研究以太陽能為主)的推廣，皆是靠各國政策面的補助，否則產業無法持續永久。尤其是在總體經濟環境不佳時，將會造成採購停滯。因此如何找出產業發展之利基，將是本研究之重點。本研究以成本觀點，來探討如何能發揮再生能源之經濟性。而研究資料是以國內外的發電成本及能源補助措施之相關數據，來進行分析。而本研究乃從業內及業外兩個構面，來進行探討各項發電之相關成本：如系統設置、發電結構，並納入碳權經濟中排放交易及保證躉購電價制度之因素，來分析再生能源推廣之經濟。 本研究之結果顯示：傳統電廠之發電成本乃是推動再生能源成功與否之關鍵因素。同時，不同裝置容量成本，亦會影響消費者安裝太陽能的意願。本研究，經由成本敏感性分析可得知：現今太陽能發電是不具有推廣吸引力，而此乃因其發電成本(＄4 62元/度)將比現有台電之發電成本(＄2 82元/度)高。顯然的，在目前電價的條件，且太陽能裝置成本不變下，則唯有提高發電成本至某一合理價格(＄4 94元/度)時，太陽能發電才具經濟可行性。[[abstract]]The climate changes and worldwide energy shortage have driven countries to take note of the issues of saving energy and reducing carbon emission Governments have devoted themselves in developing alternative energy projects and renewable energy subsidy policies in the hope to reduce greenhouse effects and promote the development of renewable energy industry The promotion of renewable energy (namely the “solar energy” in this study) depends largely on national subsidies to sustain the development of the industry Bad macroeconomics would cause the stagnation of the sales of solar energy products Therefore it is the purpose of the study to discover the niche for the industrial development In view of costs the study discussed how renewable energy could exert its economic function The research data included the electricity generation costs and energy subsidies in Taiwan and in other countries The study discussed from both in-the-industry and non-business dimensions about the related costs in generating electricity such as system installation electricity generating structures with the consideration of carbon emission rights trading and feed-in tariffs and analyzed the possibility of renewable energy economy The results showed that the electricity generating costs of conventional electricity plants were the determinants to the success of renewable energy development In addition the costs for installing the devices of various sizes also influence consumers’ willingness to use solar energy From the cost sensitivity analysis the study found the reason why solar energy was not so appealing to consumers was that its generating cost of $4 62 per degree was much higher than the conventional electricity provider -- Taipower’s $2 82 per degree Apparently under the current electricity price structure and with current installation costs of solar energy devices only when the conventional electricity generating costs rise to a more reasonable price for instance $4 94 per degree would the solar energy reach its economic feasibilit
