What is the difference between 浪费 and 耗 ?

Question

LucienK · Answer

I think 浪费时间 basically means wasting time.
耗时间has 2 meanings which depend on the context.
One is cost much time, like 花时间
这个项目很耗时间（this project costs a lot of time)
The other, well, hard to explain how:
你都耗在家里一天了！you've been at home for a whole day! Maybe it's because he did nothing and wasted a whole day. Maybe he should have gone out and done some exercise.
耗seems to have a wider range of usages and more of spoken language.

浪费 比如 开着灯很浪费电，指的是开不开灯都可以，不一定要开灯。   耗 比如 这个机器很耗电，指的是想要让这个机器运转就需要很多电。 总之 浪费是没有必要做的事却做了，能源不一定是需要的。耗是想要运转一件事物就必须需要这些能源。

举个例子：
1.这节中文课，老师讲得太差了，浪费时间（浪费时间=waste of time）
2.这节中文课我不感兴趣，等待下课的时候，在想中午吃什么，耗时间（maybe 耗时间=dawdle）
