Nonrenewable 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. A natural resource is something supplied by nature that helps support life. When you think of natural resources , you may think of minerals and fossil fuels. However, ecosystems and the services they provide are also natural 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.

Chapter 13 ~ Non-Renewable 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. Where does the energy used in our home come from?

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.

Examples of Nonrenewable Resources

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.

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. Human beings are depleting the planet's natural resources.

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.

Software helping U. While the universe is infinitely expanding, the very resources that power the Earth are running out. The rest was powered by nonrenewable resources. According to the U. Fossil fuels are formed from organic carbon material that has been heated and compressed over millions of years. To put it another way—our most frequently used energy sources like oil and coal are made from the buried remains of plants and animals from millions of years ago.

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. They fall into two categories: nonrenewable and renewable. Nonrenewable energy resources, like coal, nuclear, oil, and natural gas, are available in limited supplies.

Renewable and nonrenewable resources are energy sources that human society uses to function on a daily basis. The difference between these two types of resources is that renewable resources can naturally replenish themselves while nonrenewable resources cannot. This means that nonrenewable resources are limited in supply and cannot be used sustainably. There are four major types of nonrenewable resources: oil, natural gas, coal , and nuclear energy. Oil, natural gas, and coal are collectively called fossil fuels. They are found in underground layers of rock and sediment. Pressure and heat worked together to transform the plant and animal remains into crude oil also known as petroleum , coal, and natural gas.

A nonrenewable resource is a natural resource that cannot be re-made or re-​grown at a scale comparable to its consumption. Page 4. NUCLEAR ENERGY.
