Why do scientists and educators find it difficult to be precise when declaring a resource as “renewable”?
A renewable resource is a resource that can be replenished naturally with the passage of time. 
Scientists and educators find it difficult to be precise when declaring a resource as “renewable” because the future is unknown for certain. Drought could cause lakes and rivers to dry up. Clouds could cover the sun for days. Also the demand for the supply could be too much. All the trees used up before more can be planted.
The growing population growth has no limits on how much resource is going to be needed or used. This makes an exact science of what is going to happen with a renewable resource impossible to be exact. It is easy to say although, that the sun will be around for as long as the planet is here and people are alive. The sun would be the best source of energy.
