Non-renewable resource - Wikipedia
Fossil fuels and nuclear fuels are examples of non-renewable resources. 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 See similar articles. Non-renewable sources such as fossil fuels (coal, oil, natural gas) will technically replenish, but over many, many, thousands of years meaning we use them up. There are four main types of non-renewable energy sources, which are oil, natural gas, coal and uranium. Did you know there's oil in your crayons? Oil is a very It's the energy source used in nuclear power plants to produce electricity .
While geothermal creates very little environmental impactthere are still some concerns about what impact it does create. Vulnerable in Certain Areas: Areas prone to earthquakes or other seismic activity are not ideal for geothermal power plants. Heavy Costs up Front: Constructing the power plant and the heating and cooling system costs more upfront than other types of renewable energy. Geothermal resources have to be managed or they can run dry.

Biomass Biomass energy uses the natural process of photosynthesis and other biological energy production that occurs with organic subjects. If you can grow it, it can be used in biomass energy production. This makes it a highly renewable source. This is one of the few forms of energy that is considered to be carbon neutral. It does have a carbon impact, but it is considered to be part of the natural carbon cycle on the planet and causes no additional burden on the atmosphere.
Over 10 to 15 years of use, the average user will see a significant savings in energy cost. Wherever you can grow you can create biomass energy.
There is no need for extra transport such as pipelines to deliver it to areas. This can be one of the more expensive energies to produce as it is dependent on a growing and harvesting cycle.
While new technologies are being developed to allow for plants to used smaller spaces, right now extensive space is needed to grow enough of the biomass to produce energy. Growing requires water and that can be a problem in some areas of the world and would limit the effectiveness of biomass energy production.
Hydro power Hydro power harnesses the power of water flow to generate electricity by using the flow to turn turbines. In many ways this is one of the cleanest technologies, but it also has a cost that has to be considered. Using hydro power reduces the need to burn fossil fuels. The output from the plant also has a very light carbon and air pollutant emission rate.
While costly to build and having a high maintenance budget, the long term cost of a hydro power system is much cheaper than traditional power plants. Water exists on the Earth and in the atmosphere. It is constantly renewing itself so this makes hydro power a renewable energy source. If you view water as a raw material, and the reservoir as the holder for that material than you can see that there are multiple uses for the water at the same time it is used for power.
It can host wildlife, irrigate farmland, provide drinking water and be a point of recreational activities for the community. Cons Marine Life Endangerment: While building a dam creates a reservoir that becomes a marine habitat, it only does so by destroying the natural one that exists.
This can interrupt the ecology of the area. Also, the turbines used by the power plant can hurt the fish population by changing the currents in the water and interrupting feeding and spawning patterns. This is the term used to describe such factors as drought that can change the expected capacity of a hydro power plant. As of yet, there is little man can do to control certain natural occurrences that can reduce the plants output.
Implementation and Maintenance Cost: Hydro power plants are very expensive to build, and they also have a high maintenance cost. Unlike other types of power that are contained within a plant, hydro power must also care for off site entities such as dams, reservoirs and river systems. Imminent Danger to Human Populations: This means that they were formed from the remains of plants and animals eons ago. Fossils fuels can be in a solid, liquid, or gas form.
Fossil fuels such as coal, natural gas, and crude oil takes millions of years to form, emphasizes National Geographic. Fossil fuels are mainly made of carbon, as their origin is the remains of dead plants, algae and plankton which settle into seas or lakes. Over hundreds of million of year sediments accumulated and buried them underneath "creating pressure and heat.
So when fossil fuels are burnt carbon that has been collecting for millions of years is released and add to the environment. Oil and Petroleum Products The BBC reports that oil reservoirs are found between rocks, which can be pumped through pipes easily. As reservoirs dry up, industries are turning to heavier crude oil in tar sands and shale that is more difficult, polluting and expensive to extract.
As EIA Non Renewable explains, crude oil is processed and refined to make petroleum derivatives such as gas or dieselpropane, butane, and ethane. Various other non fuel products like plastics, fertilizers, pesticides and pharmaceuticals use crude oil as a major ingredient according to EESI. Once the oil is taken out of the ground, it is gone forever. The earth can replenish oil only in geological time spans.

Natural Gas Similar to crude oil, there are two types of natural gas, explains Union of Concerned Scientists. Conventional natural gas is found in porous rocks that can be easily tapped by wells and pipes. Unconventional natural gas like "shale gas, tight gas, coal bed methane, and methane hydrates, has been more difficult and costly to exploit than conventional deposits, until recently.
It's also used for heating and electricity for buildings, according to EESI. A variety of other products need natural gas for production, like fertilizers and plastics. Coal Coal is the solid form of the three fossil fuels. The World Coal Association states that U.
Coal must be mined to be removed from the earth and there are two types of mining: Underground mining is used for deeper coal pockets. S in according to the EIA's coal report.
A Guardian report accounts this decline foremost to availability of cheap natural gas, and secondly to a spike in growth of wind and solar power generation, along with an emphasize to reduce emissions, as coal is the most polluting of all fuels. It is more abundant than gold or silver.
High grade uranium is extracted with "mining techniques such as dust suppression, and in extreme cases remote handling techniques, to limit worker radiation exposure and to ensure the safety of the environment and general public," writes the WNA. Uranium is used in nuclear energy plants as well as in other ways. Like the fossil fuels, once uranium is taken from the earth, it can't ever be replaced.
Not Just Fossil Fuels Though these fossil fuel energy sources are the most widely publicized non-renewable energy sources, there are others, like minerals, whose supply is fixed.
Indiana University explains that many minerals were formed in stars and during the formation of earth and are present in its core and crust. Tulane University notes that about 20 to 30 minerals are of importance; some combine to produce rocks.
To extract these minerals, the rocks or ores are mined and then refined or processed. If humanity were to exhaust any of these crucial and useful minerals, it is nearly impossible to replace them.
