Is biomass renewable or nonrenewable

It is a renewable source of energy because ALL vegetation gets its energy from the sun and regrows. Oil would not be an example of renewable energy because it takes millions of years to produce.

It is definitely currently a renewable source of energy, but consider this. Biomass is renewable because it does not take 100,000 years or more to make it or for it to be made like oil. We can grow new crops, new trees, and they grow fast enough to use. But if we had only them would they still be renewable? It also takes a large amount of product to make biomass (like fertilizer to grow crops) and the prices go up, the more of it that is used (like the spikes in the cost for corn we have seen).

Is it renewable, yes. Should it be? To an extent. If we had only that would it be like oil where we could not make enough? Of course.
