Heritage Middle School wants to begin heating their school with natural gas in the fall of 2020. There was a meeting to discuss this change at central office last night. Mrs. Williams states that she does not believe this will be a good change in the long run. Why does Mrs. Williams have this opinion?
Natural gas is a non-renewable resources. Non-renewable resources are not easily replaced in a short amount of time.

Define Inverse Relationships from the energy unit.
Inverse Relationships: when one type of energy changes, the second type of energy changes.
Example: When potential energy increases, kinetic energy decreases. When potential energy decreases, kinetic energy increases.
