参考解析：

推理判断题。根据文章第三段最后三句“How soon we reach an era of clean, inexhaustible energy depends on technology. Solar and wind energies are intermittent: When the sky is cloudy or the breeze dies down, fossil fuel or nuclear plants must kick into compensate. But scientists are working on better ways to store electricity from renewable sources”可知，我们何时才能进入一个清洁，取之不尽用之不竭的能源时代，取决于科技。太阳能和风能是间歇性的：当天空多云或微风减弱时，化石燃料或核电站必须起到补偿作用。但是科学家们正在研究更好的方法来储存可再生能源的电力。故选B。
