課程說明
Course Description
人類應不應該繼續使用核能發電,在世界各國都是一個頗具爭議的問題。在國內，是否應該興建核四廠已經爭議了近二十年，核四成了政治的圖騰，成為政黨興衰與個人意志力的象徵。民進黨執政後，以迅雷不及掩耳的方式，宣佈停建核四，接著在在野黨的脅迫下，恢復核四的興建，一停一續之間，衝擊了人們對執政黨的信心，成為造成經濟衰退的最後一根壓死駱駝的稻草。林義雄先生對核四公投的堅持，也直接的促成了公投法的通過。為了對環保團體有所交待，張俊雄院長在宣佈核四復工時，同時聲稱推動”非核家園”政策。七年來，未見政府依程序，將”非核家園”列為正式之國家政策。
2003年，國際化石燃料價格開始飆漲；2005年2月，抑制二氧化碳排放的京都議定書生效；已開發國家開始積極尋求可以替代化石燃料產生大規模動力的能源。核能發電成本較不易受到國際能源價格波動影響，以及不排放二氧化碳的兩項重要特質，重新獲得該有的重視。 核能發電所使用的燃料體積小，運輸貯存方便；核能發電成本中，燃料成本所佔的比例較低，故其發電成本較穩定，不易受到國際燃料價格的飆漲影響而有大幅度的波動。因此，能源依賴進口國家均將核能視為準自產能源。台灣超過99%的能源依賴進口。
核能發電能減少產生二氧化碳，行政院第二十五次科技顧問會議（94年4月22～23日）中，美國麻省理工學院物理系教授莫里茲博士明白的指出：「如果在考慮二氧化碳減量時，不考慮核能，及無法為這個問題找到解決方案（If you exclude nuclear power from the solution, there is no solution）」。世界各主要國家（如美國、英國、法國、俄國、加拿大、日本、韓國、中國大陸）都認同此項看法，也都以核能為控制二氧化碳排放的主要工具。三年前，馬總統剛接掌政權時，經濟部發表之「能源安全策略報告」 中，擬定二氧化碳減量目標為「於2016至2020年回到2008年排放 量，並於2025年回到2000年排放量」，2000年的排放量為214.5百萬噸。馬總統5月19日在台南大學和近300名大學生座談，274名學生支持減碳優先，只有11名學生認為廢核優先。
全力發展再生能源是無悔的政策，但我們必須認知下面的現實。再生能源最大的問題為能量密度非常低，需有廣大的土地面積來收集。台灣人口占世界之0.3％，土地面積僅占世界之0.06％，而我們的能源消耗為全球之1％，以單位國土面積耗能來說，台灣排名世界第一，是美國的10倍、日本的近2倍、德國的近3倍、荷蘭的1.3倍。
Whether humans should continue to use nuclear power or not is a controversial issue in the world. In Taiwan, whether we should build the fourth nuclear power plant has been argued for nearly 20 years; moreover, the 4th plant becomes the totem of politics, and the symbol of politic party’s rise and fall and personal perseverance. After starting to be in power, DDP announced to stop establishing the 4th plant in a thunder-like quick way. Next, under the threat of the opposition party, the government restarted the build. Because of the quick change of the decision, people lost the faith of ruling party, and it became the last straw of economic recession. Due to Mr. Lin,Yi-Xiong’s consistence, it also directly promoted the pass of Referendum law. In order to give environmental groups a satisfactory answer, Premier Chang,Chun-Hsiung claimed to promote “nuclear-free homeland” policy simultaneously. For 7 years, we still cannot see the government to list “nuclear-free homeland” policy on the formal national regulations by administrative order.
In 2003, the price of International fossil fuels began soaring. In February, 2005,
Kyoto Protocol, which restrains the emission of carbon dioxide, has become effective. Developed countries set up to seek for the energy which can alternative fossil fuels to produce large-quantity power. The cost of nuclear power is not prone to be influenced by the price volatility of International energy, and nuclear power doesn’t generate carbon dioxide emissions. Above two critical features, nuclear power regains value and importance.
The fuel of nuclear power takes up little volume and is able to be easily transported and stored. The proportion of fuel cost in the nuclear cost is relatively low, so the cost is more stable, which means it’s not easily to be influenced by the international fuel price. Therefore, countries which depend on import energy see it as quasi-homegrown energy. Over 99% of Taiwan’s energy relies on import.
Nuclear power can reduce carbon dioxide emission. In the 25th Executive Yuan Technological Consultant Conference (94/4/22-23), Dr. Moritz, physics department in MIT, clearly suggested, “If you exclude nuclear power from the solution, there is no solution.” The chief countries in the world (ex. the United States, the United Kingdom, France, Russia, Canada, Japan, Korea, and China) all agreed with this argument, and also use nuclear power as the main way to control the emission of carbon dioxide. 3 years ago, when President Ma was just in power, in the” Policy Report of Energy Security “by Ministry of Economic Affairs, it set the goal of carbon dioxide reduction to be “reduce the amount in 2016-2020 to the 2008’s amount, and the one in 2025 back to the amount in 2000,” and the emissions in 2000 is 214.5 million tons. President Ma had a discussion with about 300 college students in National Tainan University on May 19th—247 students are for the priority of carbon reduction, and only 11 of them consider non-nuclear is more important.
Rendering full development to renewable energy is regretless policy, but we must acknowledge the fact: the biggest problem of renewable energy is that energy density is extremely low, and that it needs a broad land to collect the energy. Taiwan’s population accounts for 0.3% of the world’s total population and our land merely accounts for 0.06%, while our energy consumption takes up 1% of the globe. In terms of energy consumption per unit national land area, Taiwan ranks first in the world, which is 10 times of America, nearly 2 times of Japan, about 3 times of Germany, and 1.3 times of Netherland.
