A non-renewable resource (also called a finite resource) is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption. [1] An example is carbon-based fossil fuels.
Nonrenewable resources are natural substances that are not replenished with the speed at which it is consumed. As such, a nonrenewable resource is a finite resource....
The choice between renewable and nonrenewable resources is not just a matter of replacing one with the other; it involves a complex consideration of environmental impacts, costs, infrastructure needs, and technological advancements.
Nonrenewable energy comes from sources that will run out or will not be replenished in our lifetimes—or even in many, many lifetimes. Most nonrenewable energy sources are fossil fuels: coal, petroleum, and natural gas. Carbon is the main element in fossil fuels.
Nonrenewable Resources. Nonrenewable energy resources include coal, natural gas, oil, and nuclear energy. Once these resources are used up, they cannot be replaced, which is a major problem for humanity as we are currently dependent on them to supply most of our energy needs.
Fossil energy sources, including oil, coal and natural gas, are non-renewable resources that formed when prehistoric plants and animals died and were gradually buried by layers of rock.
Learn how human use of fossil fuels—non-renewable energy sources, such as coal, oil, and natural gas—affect climate change.
Non-renewable energy sources. Energy comes from many sources, and to describe these sources we use two terms: renewable and non-renewable. Non-renewable energy resources cannot be replaced – once they are used up, they will not be restored (or not for millions of years).
Definition. Non-renewable resources refer to natural resources that cannot be regenerated once depleted. These non-renewable resources can’t be easily formed or regenerated in a man’s lifetime because they regenerate at a much slower rate as compared to the rate of their depletion. In fact, non-renewable resources take centuries to form.
Nonrenewable Resources. Nonrenewable resources are natural resources that exist in fixed amounts and can be used up. Examples include fossil fuels such as petroleum, coal, and natural gas. These fuels formed from the remains of plants over hundreds of millions of years.
