考查地点状语从句。句意：我们将在水源资源丰富的地方建造一座发电站。分析句意可知，此处并不是水电站的水资源丰富而是将水电站建在资源丰富的地方，所以从句没有先行词，属于状语从句。故选A。
【名师点睛】
本题考查地点状语从句，同学们很容易弄混定语从句和状语从句。最简单的办法是看where是否有指代先行词，具体可从以下两点来看：
一、where引导定语从句时，where是关系副词，在从句中作地点状语，其前面有表示地点的先行词。例如：
The bookshop where I bought this book is not far from here.
This is the house where I lived two years ago.
We will start at the point where we left off.
