科技進步v.s.設備成本降低=>太陽能發電更cost-efficient
However,經濟上的threshold仍沒有改變。
問原因:
答:因為科技的進步也增加oil-fired power的efficiency
(你進步了人家也進步了,所以你落後人家的程度是沒變的!大概這意思...)
※ 引述《BGjay (逼機)》之銘言：
: Technological improvements and reduced equipment costs have made converting
: solar energy directly into electricity far more cost-efficient in the
: last decade. However, the threshold of economic viability for solar power
: (that is, the price per barrel to which oil would have to rise in order for
: new solar power plants to be more economical than new oil-fired power plants)
: is unchanged at thirty-five dollars.
: Which of the following, if ture, does most to help explain why the increased
: cost-efficiency of solar power has not decreased its threshold of economic
: viability?
: 答案是C
: Technological changes have increased the efficiency of oil-fired power plants
: 有哪位高手可以跟我解釋一下嗎
: 基本上我看不太懂這題
