New technologies will be needed for photovoltaics to become cheap.

為了讓光能發電變便宜，新科技得派上用場。

Fact 1：The primary ingredient of most solar panels is purified sand. Fact 2：Enough sunlight hits the Earth in an hour to provide all of humanity’s energy needs for a year. So why isn’t solar power cheap and abundant?

事實1：大部分太陽能面板的基本成分是淨化後的砂子。事實2：太陽光照射在地球1小時的能量，足以提供人類1年的能源需求。如此說來，為什麼太陽能不能既便宜又豐沛？

For starters, building a device capable of turning incoming photons into electricity isn’t cheap. Add in installation and the cost of a solar system can still be more than $10 per watt of electricity produced. That’s much higher than the cost per watt from burning coal or natural gas.

對入門者來說，建造一個可以將光能轉為電能的裝置並不便宜。增添安置一套太陽能發電系統，其每瓦特發電費用仍超過10美元（約306台幣）。這比燃煤或天然氣每瓦特發電成本還高出許多。
