But not every target is helpful.(主题句) " p( O* G D5 v
To see why, consider that goal of 100% renewable energy. It makes solving climate change seem deceptively easy.(例证)

- i* i. L- V) {/ _原因之二,这一小节的主题句。# N$ `, B* d$ u
上一节讲用清洁能源发电,这一节讲即是发电100%用可再生能源,对于减少碳排放也没什么大的用处,杯水车薪而已。4 f4 j5 [! `# M7 v
Even though gas-fired heating and cooking can be at least as big a source of greenhouse-gas emissions(as coal-powered electricity generation), renewable heating gets minuscule attention.

燃气取暖、做饭作为碳排放源≥燃煤发电,但可再生能源取暖却并没有得到重视(minuscule形式是肯定,语义却是否定的)

原因之三,主题句。0 Y c) g) j* r& P0 R
交通工具也是一个巨大的碳排放源,但是这方面的政策却缺乏一致性、连贯性。4 F# A" G/ G0 o1 C' T' y3 s
. k! ^* ?; e& m" T7 x Carmakers may hit their goal of annual sales of 10m electric vehicles in a decade, but battery-powered road haulage, shipping and aviation are dreams. A much-quoted claim that America could rely on wind, solar and hydro alone for its electricity has recently been witheringly criticised by a group of respected academics.& M$ O1 y# }0 d9 b# v

私家车,公路货运,航运,空运都是碳排放源,但是政策却缺乏一惯性。9 N0 v) E& C& i1 k! z3 i/ ^1 n
交通运输全部用可再生能源根本不切实际。

这样的一个篇章结构如果看不明白,而去在那里钻牛角尖,实在得不偿失啊,呵呵
