AICE Environmental Case Studies Practice Exam

Renewable resources replenish naturally on human timescales, while non-renewable resources are finite. This distinction is central to sustainability because it shapes how we think about long-term availability and how we plan, manage, and transition resources. If a resource is renewable, the issue becomes using it at a rate that does not exceed its replenishment and dealing with challenges like intermittency and ecological impact. If a resource is non-renewable, the concern is depletion and the need for efficiency, substitution, or a shift to alternatives as reserves fall. This idea underpins case studies that compare future supply, environmental costs, and policy choices. It’s also important to recognize that renewables are not automatically abundant and do not remove all pollution, and that some non-renewables can have lower emissions or costs in certain contexts.
