[l]此外，核能最終是否是一種廉價的能源還值得商榷。比如說，在美國、英國、當然還有俄羅斯，都發生了代價高昂的事故。鈾的成本有可能提高，加上更加安全的防范設施所需的巨大成本會使核能的價格超出市場接受能力。環境保護論者宣稱，從長遠角度看，核能浪費了寶貴的資源，對生態的破壞甚至會達到毀滅人類的地步。因此，如果我們想繼續生存下去，我們就不能使用核能。盡管有上述種種反對使用核能的理由，核能的開發計劃還在擴大。[4]這種擴大以工業生產和消費需求的繼續增長為前提。但是，這種增長是否能夠持續，這令人懷疑。[1/5]權衡了兩個方面的意見，我們似乎有很好的經濟和生態環境方面的理由來利用其他形式的能源，而不是核能。
