So why isn't solar power cheap and abundant?
为什么这些便宜的太阳能不能为我们所用呢?
For starters, building a device capable of turning incoming photons into electricity isn't cheap.
就启动装置而言,建造能吸收光子能量转变为电能的设备并不便宜tI_P|bKua^g8D4ZdX76*
Add in installation and the cost of a solar system can still be more than $10 per watt of electricity produced.
而且将现有设备改进增加这类装置以及包括购买的这个普通的太阳能收集转换系统后也的用电花费也会超过每度电10美金WQIO2E&STyv~

New developments could include growing pure silicon wafers rather than sawing them from long ingots; or even fundamental shifts in the physics employed, like using so-called black silicon or quantum dots.
新的发展方向应该包括生成纯硅晶片而不是重塑形状或甚至改变它们已生成的原始物理基本特征,比如采用被称为黑色硅晶或量子态颗粒**l5jybo_m@u-TBSc
Of course, if all energy sources paid their full price, solar would be more competitive.
当然,如果综合计算所有的现有人类可用能源,太阳能还是比较有竞争力的.FQgloDLm3D=Oo]G]
After all, making solar panels doesn't result in nearly as much mercury, CO2 and other pollution as spewed by coal-fired power plants.
毕竟,制造一块太阳能聚光板并不会造成燃煤火力发电工厂向周围环境中喷射水银,二氧化碳温室气体和其它污染物那样的严重后果4R^bV5Fneu[n,SMS,Meq
If the health and environmental costs of coal or natural gas were included in their prices, suddenly solar might look a whole lot cheaper.
如果煤炭或天然气所带来的健康和环境消费也被算入成本的话,你会突然发现太阳能真的非常便宜fj5*=aZ9])
