Examples of Nonrenewable Resources

Nonrenewable resources are resources that have a limited supply. A lot of our fossil fuels, such as oil, are nonrenewable resources. In other words, if we keep using them, they will eventually run out.

In many of the examples of nonrenewable resources below, the supply comes from the Earth itself. However, since it typically takes millions of years to develop, these resources are finite. Nonrenewable energy can generally be separated into two main categories: fossil fuels and nuclear fuels.

Fossil fuels are derived from organic matter which has been trapped between layers of sediments within the Earth for millions of years. Organic matter, typically plants, have decomposed and compressed over time, leaving what are known as fossil fuel deposits. These deposits, and the materials produced from them, tend to be highly combustible , making them a potent energy source. However, many consider fossil fuels to be worth the effort for the sheer amount of energy they produce.

Crude oil is a nonrenewable resource that builds up in liquid form between the layers of the Earth's crust. The liquid is then refined and used to create many different products. Crude oil is a very versatile fuel and is used to produce things like plastics, artificial food flavorings, heating oil, petrol, diesel, jet fuel, and propane. Petroleum deposits that begin to form underground are known as oil sands, bitumen, or bituminous sands.

Bitumen is too thick to be pumped under natural conditions. Scientists refer to it as cold molasses. With special machinery, much of this is being mined in Alberta, Canada, serving as a major energy source for Canadians as well as people all around the world. Natural gas gathers below the Earth's crust and, like crude oil, must be drilled for and pumped out. Methane and ethane are the most common types of gasses obtained through this process. These gases are most commonly used in home heating as well as gas ovens, stoves, and grills.

Russia, Iran, and Qatar are the countries with the largest recorded natural gas reserves. Coal is the last of the major fossil fuels. Created by compressed organic matter, it is solid like rock and is obtained via mining.

Out of all countries, China produces the most coal by far. In fact, it has been the largest producer of coal for the last three decades, producing more than 3 billion tons of coal each year. Coal is most typically used in home heating and the running of power plants. The other form of nonrenewable resource used to produce energy, nuclear fuels, is primarily obtained through the mining and refining of uranium ore. Uranium is a naturally occurring element found within the Earth's core.

Most uranium deposits occur in small quantities which miners gather, refine, and purify. Once gathered, the uranium is brought together and compounded into rods. The rods are then submerged into tanks of water. When it reaches critical mass, uranium begins to break down and release energy which heats the water it is immersed in.

The breaking down is known as fission. The heated water then creates pressure. This pressure drives the turbines that generate electricity in nuclear power plants. Relying heavily on an energy source that could potentially run out seems like a dangerous endeavor, right? Until we change the way we motorize our vehicles, why not take a look at the things we can preserve? Home Examples Examples of Nonrenewable Resources. Oil wells represent a nonrenewable resource.

Non-renewable resource

A non-renewable resource also called a finite resource is a natural resource that cannot be readily replaced by natural means at a quick enough pace to keep up with consumption. The original organic matter, with the aid of heat and pressure, becomes a fuel such as oil or gas. Earth minerals and metal ores , fossil fuels coal , petroleum , natural gas and groundwater in certain aquifers are all considered non-renewable resources, though individual elements are always conserved except in nuclear reactions. Conversely, resources such as timber when harvested sustainably and wind used to power energy conversion systems are considered renewable resources , largely because their localized replenishment can occur within time frames meaningful to humans as well. Earth minerals and metal ores are examples of non-renewable resources. The metals themselves are present in vast amounts in Earth's crust , and their extraction by humans only occurs where they are concentrated by natural geological processes such as heat, pressure, organic activity, weathering and other processes enough to become economically viable to extract.

Nonrenewable resources are resources that have a limited supply. A lot of our fossil fuels, such as oil, are nonrenewable resources. In other words, if we keep using them, they will eventually run out. In many of the examples of nonrenewable resources below, the supply comes from the Earth itself.

OVEREXPLOITATION OF NATURAL RESOURCES

All forms of energy are a natural resource. Energy resources are categorized as renewable or nonrenewable. Renewable energy resources can be replenished over a relatively short period of time and include resources such as solar, wind, water hydro , biomass and geothermal. Nonrenewable energy resources are available in limited supply and cannot renew at sufficient rates compared to the use of the resource. Examples include coal, nuclear, oil and natural gas.

The post you are on right now was written in Please see this updated article with more current information, including new sections on climate change and nuclear power. There are nine major areas of energy resources.

That's like asking the difference between having an endless supply and having a limited supply. Will this planet eventually run out of oil? So oil is a nonrenewable resource.

Nonrenewable Resources

Natural resources are those that the planet offers without the need for human intervention. They are essential our survival, but if they are consumed at a faster rate than their natural regeneration, as is currently the case, they can be exhausted. Then, we review the consequences and possible solutions to this problem.

One environmental issue that has been of prominent concern in the 20th century has been the growth in human population. The chart below, from the population reference bureau, illustrates the dramatic growth in human population beginning around the year As human population has grown the demand for resources of all kinds has also grown. Supporting more people means producing more food, which in turn requires greater amounts of energy, soil nutrients, water, and other resources associated with agricultural production.

As we noted in Chapter 12, the reserves of non-renewable resources are inexorably diminished as they are extracted from the environment and used in the human economy. This is because non-renewable resources are finite in quantity and their stocks do not regenerate after they are mined. Note that the word reserve has a specific meaning here — it is used to denote a known amount of material that can be economically recovered from the environment that is, while making a profit. Of course, continuing exploration may discover previously unknown deposits of non-renewable resources. If that happens, there is an increase in the known reserves of the resource. Changes in the value of non-renewable commodities also affect the sizes of their economically recoverable reserves. An improvement of technology may have the same effect, for instance, by making it profitable to process ores mine that were previously non-economic.
