What does it mean that a source of energy is nonrenewable? (1 point)
1. What does it mean that a source of energy is nonrenewable?
There is only a limited supply that can be used.
2.Crude oil was formed millions of years ago from the remains of living things. Where is crude oil found today?
under dry land and under the ocean
3.Which fuel creates the most air pollution when burned?
coal
4. When were fossil fuels formed?
millions of years ago
100% correct
It means that the source of energy cannot be replenished once it has been used up and therefore it is finite and not sustainable in the long term. Examples of nonrenewable sources of energy include fossil fuels such as coal, oil and natural gas.
! Well done!
To understand what it means for a source of energy to be nonrenewable, let's break down the term:
1. Source of energy: This refers to any natural resource or technology that can be converted into usable energy. Common examples include fossil fuels (coal, oil, natural gas), nuclear energy, and certain minerals.
2. Nonrenewable: This indicates that the source of energy is limited in quantity and cannot be naturally replenished within a reasonable timeframe. Once these resources are used up, they cannot be replaced in the short term, making them finite in supply.
In practical terms, nonrenewable energy sources are generally derived from ancient deposits that took millions of years to form, such as fossil fuels formed from ancient plant and animal remains or minerals created by geological processes. Since the rate of consumption of nonrenewable energy sources typically exceeds their formation, they are deemed nonrenewable.
It's important to note that the scarcity of nonrenewable energy sources has several implications. First, they are not sustainable in the long run, as their availability will eventually be depleted. Second, the extraction and use of nonrenewable energy sources often have negative environmental impacts, such as greenhouse gas emissions or habitat destruction. These factors have led to a growing emphasis on transitioning to renewable and more sustainable sources of energy.
