What problems might occur if we use up nonrenewable energy resources

the answer to fill in the blank in this question would be the word resource, it is defined as the money, material or people (since human resource is a very valuable good) that a company or a person has at disposition (meaning they can use the resource as they see fit), to be able to complete a task or achieve a goal.  

workers should be given a fair share of the wealth their work creates

hope this
