推 butkam:發電成本有差...電價也許會受影響 04/24 19:49
發電成本當然有差,因為我們缺乏台電以外的發電數據,
很有理由可以相信台電低估核能發電的成本,
因為台電與反核人士就核電成本上最大的爭議點:
『核廢料處理成本與核電廠除役成本』為例,
基本上完全處於各說各話階段,反核人士完全不相信台電所言的核廢料處理成本,
而就在這裡,出現巨大的差異。
而且其實,台電總經理也不敢說到底要花多少錢。

不過沒關係,我們嘗試分析一下。
http://www.taipower.com.tw/content/govern/govern01.aspx?MType=17
這是103年三月底為止的台電發電成本,原則上這個成本已經列入廢料,
不管是核廢料還是煤渣的處理成本,當然,反核人士完全不相信台電的
核廢料處理成本。
根據這份表,前一篇中所列前三大發電項目台電自己的發電成本如下:
燃煤:1.35元/度
燃氣:3.94元/度
核能:0.92元/度
在前一篇文章中有提到,當日尖峰時間前三大發電項目數量如下:
燃煤 714.9+民營238.2=953.1
燃氣 784.4+民營378.5=1162.9
核能 321.8
我只算一個概念,所以我把民營發電量併入總發電量,也不管單位,
並以台電成本估計之。
於是總發電成本為953.1*1.35+1162.9*3.94+321.8*0.92=6164.567
如果核電歸零,並以燃煤取代,則成本為6302.941,約增加2.2%。
如果核電歸零,並以燃氣取代,則成本為7136.403,約增加15.8%。
一樣,核三廠歲修中,但其他火力發電廠也有在歲修中,
不過觀念如此,差異不大。
也就是如果核電歸零,並全部以火力中最環保的天然氣取代,大概漲16%,
如果狠一點全部用煤炭取代,不到3%。
漲這點錢當買保險我個人以為相當值得,而且請注意,
這是在低估核廢料處理成本下取得的數字。
→ gbid:下次會不會有人出來反火力發電廠,空氣污染問題 04/24 22:12
就算燒天然氣,成本也漲16%,更何況燃煤發電真的比核廢料毒嗎?
推 FunnyGuitar:IPCC已經點名台灣了 不需要台灣自己說什麼 04/24 22:18
我不清楚IPCC有點名台灣,不過無所謂,我們可以繼續檢討。
根據這份資料:
http://www.epa.gov.tw/ch/artshow.aspx?busin=12379&art=2009011715443552&path=12437
縮網址:http://0rz.tw/IoFNk
2012年統計資料顯示,燃料燃燒的二氧化碳排放數量比例如下:
工業占48.6%
運輸占14.2%
服務業占13.2%
住宅占12.9%
能源類10.4%
農業占1.1%
能源類只佔第五名。
目前核電佔台灣發電量大約18%,假設其他82%通通產生二氧化碳,
則如果核能這18%轉以其他發電方式取代這樣的高估法,
那總二氧化碳排放將為10.4/82*100=12.68%。
也就是增加12.68-10.4=2.28%。
這一點點增加量,很重要嗎?
工業為首的其他類別隨便減一點就足夠抵銷而有餘了。
