While fossil fuels-coal,oil,gas-still generate roughly 85 percent of the world's energy supply,it'sclearer than ever that the future belongs to renewablesources such as wind and solar.The move to renewables is picking up momentumaround the world:They now account for more than half ofnew power sourcesgoing on line.

Some growth stems from a commitment by governments and farsighted Businssesto fundcleanerenergy sources.But increasinglythestoryisabout theplummeting prices of renewables,especially wind and solar.The cost of solarpanels has dropped by 80 percent and the cost of wind turbines by close taone-third in the past eight years.

In many parts of the world renewable energy is already a principal energy source.In Scotland,for example,wind turbines provide enough electricity to power 95 percent of homes.While the rest of the world takes the lead,notably China and Europe,the United States is also seeing a remarkable shift.In March,for the first time,wind and solar power accounted for more than 10 percent of the power generated in the US,reported the US Energy Information Administration.

President Trump has underlined fossil fuels-especially coal-as the path to economic growth.In a recent speech in Iowa,he dismissed wind power as an unreliable energy source,But that message did not play well with many in Iowa,where wind turbines dot the fields and provide 36 percent of the state's electricity generation-and where tech giants like Microsoft are being attracted by the availability of clean energy to power their data centers.

The question“what happens when the wind doesn't blow or the sun doesn'tshine?"has provided a quick put-down for skeptics.But a boost in the storage apacity of batteries is making their ability to keep power flowing around the clock more likely.

The advance is driven in par by vehicle manufacturers,who are placing big bets on battery-powered electric vehicles.Although electric cars are still a rarity on roads now.this massive investment could change the picture rapidly in coming years.

While there's a long way to go,the trend lines for renewables are spiking.The pace of change in energy sources appears to be speeding up perhaps:just in time to have a meaningful effect in slowing climate change.What Washington does-or doesn't do-to promote alternative energy may mean less and less a time of a global shift in thought.

26—27参考答案及解析：

26.【答案】C falling

【解析】这是一道词义句意题，要想知道plummeting的意思，首先要回到原文找线索，即plummeting所在的句子以及上下句，由原文可知，plummeting所在句子是在说现在例如风能和太阳能这样的可再生资源的价格的问题，plummeting是修饰可再生资源的价格的，接着二段最后一句就在用具体数字来证明可再生资源的成本在下降，如太阳能成本下降了百分之八十，风能也降到三分之一，由此可知，可再生资源的成本在下降，plummeting的含义是下降的意思。所以选择C falling。

27.【答案】A is progressing notably

【解析】这是一道具体细节题，根据题干关键词定位至第三段第三句及第四句，意思是“在中国和欧洲等国家已经领先时，美国也在见证着巨大的改变。根据美国能源信息局报道，三月份，美国首次使用风能和太阳能产生了超过百分之十以上的能源。”这足以说明在美国，可再生能源的使用正在取得显著地进步。所以答案是A。
