Non Conventional Sources Of Energy Essay

The world is increasingly dependent upon energy. Energy powers everything from cars, electricity, to toys. Energy can be divided into two separate categories, nonrenewable energy and renewable energy. Nonrenewable energy is energy produced from nonrenewable resources like oil, coal, and natural gas. These resources are depleting; some sources believe that an energy crisis is to ensue.

Nonrenewable and renewable energy both do contain the alike qualities that they are reliable forms of energy that are both needed today for not only transportation but also for industry, and in home use. However, in contrast to one another you can clearly perceive the differences of the two energy types and how they individually portray their own unique methods of achieving their energy. Since nonrenewable energy is toxic to our environment from its burning of fossil fuels, the fact it contains a limited amount of resources that will indefinitely run out in the near future, and the point that nonrenewable energy has the ability to be used as of today, all shows great amounts of indifference to its opposing energy type; renewable energy. Renewable energy is safe for our environment and will not cause any pollution to the atmosphere, it also contains materials that are unlimited which means we can use them without the worry of them becoming scarce, and finally, renewable energy will not be able to be fully achieved until future use when the proper technology and savings is acquired for us to take advantage of it. To conclude, one can infer that there are a multitude of reasons that one type of energy is a better use than the other, but despite

This emission of greenhouse gases has increased drastically in the past few years. The main cause of this increase is due to the human activities. Many people do stuff without thinking about how their actions can affect the environment badly. Examples of such actions are: cutting down and burning of trees, burning of fossil fuels and production of refrigerants and synthetic fertilizers.

“Nuclear power will help provide the electricity that our growing economy needs without increasing emissions. This is truly an environmentally responsible source of energy.” Michael Burgess Prior to the introduction of nuclear energy, fossil fuel was thought to be the only available source in producing energy. Although fossil fuel, such as coal, petroleum, and natural gas, contains high energy value, it produces too many harmful byproducts that ultimately pollute our environment. With the rising concerns over global warming as more and more greenhouse gases accumulate in our Earth’s atmosphere, many voice such opinions that new alternative, yet sustainable method must be adopted to produce energy. Nuclear energy is one of the several alternative energy sources that have been introduced ever since.

It is also cheaper than coal or burning gas. Also the wind energy is a moral energy because it doesn’t have to kill any living thing like plants or animals to produce electricity and it uses natural wind to convert electricity, so it is better than digging in the earth to get fossil fuels and burning to get

One of the disadvantages of biofuels is that they aren’t as clean as we may think due to the use of fertiliser to grow these crops. Fertiliser is a nitrogen-rich compound, and nitrogen is consumed by bacteria that produces nitrous oxide. The release of nitrous oxide, an even more harmful GHG than carbon dioxide, into our atmosphere creates yet another dreaded greenhouse effect. The nitrogen and phosphorus present in fertilisers can also cause eutrophication which can lead to a loss of biodiversity. These aspects of biofuels serve as significant disadvantages to the

Carbon from the atmosphere is absorbed into plants during photosynthesis and when the plant decays or is burnt that carbon goes back into the atmosphere. Because it is a cycle, the next crop of plants absorb that carbon over again, so this process does not contribute much to the release of carbon dioxide into the atmosphere. 3.2 Cons of Biomass Energy 3.2.1 Requires Space Big areas are required for all the different processes that is required in harnessing energy from biomass. The areas that are needed for storing can be particular large and may lead to deforestation. 3.2.2 Emissions The principal concerns about emissions and the impact of combustion systems on air quality are in relation to carbon dioxide and carbon monoxide (〖CO〗_2 and CO), small particulates (PM10 and PM2.5; particles smaller than 10 microns and 2.5 microns respectively), oxides of nitrogen (NOx) and sulfur dioxide (〖SO〗_2).

The conventional methods are expensive and are not very effective. Thus bioremediation is the need of the hour. Bioremediation uses living organisms to degrade or remove the pollutants from a contaminated site. It is defined as “Treatment that uses naturally occurring organisms to break down hazardous substances into less toxic or nontoxic substances” (EPA). The environment has the inbuilt tendency to degrade the waste which is known as intrinsic bioremediation.

They found sources that replenished naturally in a short amount of time and are less destructive in all aspects. Due to these issues, renewable resources should become our primary source of energy. First, there are many issues with the energies sources we use now, but one of the major ones is that nonrenewable resources cannot replenish fast enough to replace what is being consumed. Energies made from fossils are the most common types of nonrenewable resource. Specifically, the three main types of fossil fuels are coal, natural gas, and oil.

Volcano eruptions, solar output (amount of energy the sun puts out), and the earth’s rotation around the sun all are natural causes in why the climate changes. Climate change caused by human interaction is mainly due to the burning of fossil fuels like coal, natural gas, oil, and other fossil fuels for energy. We are releasing a dangerous amount of carbon dioxide (CO2) in the atmosphere, which make the greenhouse effect stronger. There are two other types of gases that are also released by human activity, which is making the greenhouse effect stronger. These gases are methane (CH4) and nitrous oxide (N2O).
