Three commonly used types of renewable energy are solar energy, wind energy, and hydro water energy.

常用的三種再生能源類型是：太陽能、風力和水力發電。

Solar energy is energy that comes from the sun.

太陽能是來自太陽的能量。

You probably have seen large mirrors in solar power plants that collect sunlight.

你可能有看過太陽能發電廠中，用來收集太陽光線的大面鏡子。

But did you know that this is only the first step of getting solar energy?

但你可知這只是取得太陽能的第一步嗎？

Heat from concentrated sunlight is used to boil water.

從太陽光集中的熱氣是用來煮沸水。

This creates steam, which rotates turbines connected to an electric generator.

這產生蒸氣，用以轉動連接到發電機的渦輪風扇。

That's where electricity is created.

這就是電力產生的地方。

Interesting, huh?

有趣吧？

Just like this, the power of wind and water rotates turbines,

就這樣，利用風力和水力來轉動

which are connected to electric generators.

連接到電動發電機上的渦輪風扇。

They produce electricity.

它們產生電力。

Fossil fuels, such as oil, are becoming scarcer,

石化燃料，像是石油，變得日益稀少，

and the need to find alternative sources of energy has become more urgent than ever.

尋找替代能源的需要已比任何時候更迫切了。
