Explain how might a renewable energy source become nonrenewable
Marysya12 [62]
If you use up renewable resources faster than you can reproduce them, then they're really non-renewable. For example, if you're cutting down trees faster than they're growing, then you'll eventually run out of trees, even though they're "renewable". Technically, oil is renewable, but it takes millions of years to create, so it's non-renewable.
