风电项目的建设维护总成本约合9.19亿美元，就算加上高额的碳排放税也仅能节约1.42亿美元，这意味着该项目的价值所在 — — 节约2.61亿美元 — — 主要来自节省的10.4亿美元电费支出上。
The total cost of construction and maintenance is projected to be $919 million. Even assuming a very large carbon tax, this amounts to a rather paltry $142 million, meaning that the project’s value – $261 million in savings – stems largely from the $1.04 billion saved on electricity payments.
