What does it mean that a source of energy is nonrenewable?
A: it does not create pollution when used.
B: Once used, it needs to be reprocessed for reuse.
C: there is only a limited supply that can be used.
D: With proper administration, it can be reused.
C: there is only a limited supply that can be used.
C: there is only a limited supply that can be used.
The correct answer is C: there is only a limited supply that can be used.
To understand why a source of energy is considered nonrenewable, we need to understand the concept of renewable and nonrenewable resources. Renewable resources are those that can be naturally replenished over a relatively short period of time, such as solar energy, wind energy, or biomass. On the other hand, nonrenewable resources are those that are finite and cannot be replenished within a human timescale. These include fossil fuels like coal, oil, and natural gas.
When we say a source of energy is nonrenewable, it means that there is only a limited amount of it available in the Earth's crust. Once we have extracted and used up these resources, they are essentially gone. Unlike renewable energy sources, nonrenewable resources cannot be replenished or replaced naturally on a human timescale.
It's important to note that nonrenewable energy sources are generally associated with various drawbacks, such as environmental pollution, greenhouse gas emissions, and the potential for resource depletion. Therefore, it is crucial to diversify our energy mix by transitioning towards renewable and sustainable sources to ensure a long-term and environmentally friendly energy supply.
