The vital question is what would replace coal if were to stop using it. Judging from their chant – “No coal, no gas, no nukes, no kidding” and “Biofuels - hell no!” – the protesters in Washington would rule out many plausible alternatives.
重要的问题在于：如果停止使用燃煤，我们能用什么来取代？看看华盛顿抗议者们反复呼喊的口号吧：“不要燃煤，不要汽油，不要核能，不要欺骗”，“生物燃料—绝对不要”，显然他们将会排除许多可行的替代品。
