Alternative energy sources research paper

Current wind energy installations power roughly twenty million homes in the United States per year and that number is growing. Most states in the nation now have some form of wind energy set-up and investment into the technology continues to grow. Unfortunately, this form of energy generation also presents challenges. Wind turbines restrict views and may be dangerous to some forms of wildlife. At its most basic, geothermal power is about extracting energy from the ground around us.

It is growing increasingly popular, with the sector as a whole experiencing five percent growth in The World Bank currently estimates that around forty countries could meet most of their power demands using geothermal power. This power source has massive potential while doing little to disrupt the land. However, the heavy upfront costs of creating geothermal power plants has led to slower adoption than may have been expected for a fuel source with so much promise.

Natural gas sources have been in use for a number of decades, but it is through the progression of compression techniques that it is becoming a more viable alternative energy source. In particular, it is being used in cars to reduce carbon emissions. Demand for this energy source has been increasing. In , the lower 48 states of the United States reached record levels of demand and consumption. Despite this, natural gas does come with some issues. The potential for contamination is larger than with other alternative fuel sources and natural gas still emits greenhouse gases, even if the amount is lower than with fossil fuels.

In contrast to biomass energy sources, biofuels make use of animal and plant life to create energy. In essence they are fuels that can be obtained from some form of organic matter. They are renewable in cases where plants are used , as these can be regrown on a yearly basis. Biofuels are increasingly being adopted, particularly in the United States. They accounted for approximately seven percent of transport fuel consumption as of Water again proves itself to be a valuable contributor to alternative energy fuel sources with wave energy converters.

These hold an advantage over tidal energy sources because they can be placed in the ocean in various situations and locations. Much like with tidal energy, the benefits come in the lack of waste produced. It is also more reliable than many other forms of alternative energy and has enormous potential when used properly.

Again, the cost of such systems is a major contributing factor to slow uptake. Hydroelectric methods actually are some of the earliest means of creating energy, though their use began to decline with the rise of fossil fuels. Despite this, they still account for approximately seven percent of the energy produced in the United States. Hydroelectric energy carries with it a number of benefits.

Better yet, it also offers a number of secondary benefits that are not immediately apparent. The dams used in generating hydroelectric power also contribute to flood control and irrigation techniques. Nuclear power is amongst the most abundant forms of alternative energy. It creates a number of direct benefits in terms of emissions and efficiency, while also boosting the economy by creating jobs in plant creation and operation.

Thirteen countries relied on nuclear power to produce at least a quarter of their electricity as of and there are currently plants in operation throughout the world. The drawback is that when something goes wrong with a nuclear power plant the potential for catastrophe exists. The situations in Chernobyl and Fukushima are examples of this. When most people think of alternative energy sources they tend to use solar power as an example.

Fossil fuels are natural fuels that are formed when remains of dead organisms pass through episodes of natural processes such as decomposition and disintegration; that exceeded millions of years. Fossil fuels include coal, oil and natural gas; they are categorized as fuels due to their ability to release energy when they undergo combustion. Meanwhile, they are the main source of producing the energy that is consumed by humanity. The scope of this essay will discuss the different advantages and disadvantages of using fossil fuels as sources of energy and alternative energy sources and methods discovered by environmentalists that The water heated in the secondary loop creates steam, which is fed to a steam powered turbine generator.

This cycle continues as the steam cools and condenses back into water. In BWR, the water simply just boils and turns to steam and is fed to the steam powered turbine generator. The same process is used to cool the steam in this cycle as the other. The reactor and the generators are housed in a thick concrete-and-steel structure. The walls can be up to six feet thick. This keeps radiation from leaking out and contaminating the surrounding areas Strong Essays words 2. Alternative energy sources collectively only provide about seven percent of the total world energy supply McLamb.

Through out of history we always had a need for energy up to now we use non renewable such as fossil fuels however these will soon ran out and we have to look for different sources of energy. Energy was and remains main component of human life. People have gone from first fire to nuclear power plants and still scientists look for new types of renewable energy. In today's world , with increasing rates of consumption and as a consequence - the limited energy resources, the rapid development of technology is gaining momentum production of energy from alternative renewable sources Eventually we will get to a point where we will need to find different ways of efficiently producing energy at a low cost.

Twenty to thirty years ago it was hard to imagine what sources of energy other than obvious possibilities like solar panels and windmills that could efficiently supply the world. The advancement of technology today is opening new doors in the energy field that are likely to change the way we think about energy Good Essays words 2.

In this figure it is clearly shown just how the geothermal energy works. It is generally a collection of pipes running underground to raise and lift and put back in the hot and cold fluids found in the earth. First scientists discover a hot spot or area with a lot of volcanic activity, and then they drill into the earth very deep.

The United States has many directions to choose from in the oncoming future of energy. History has shown that surprises can change generations. The United States have relied on other countries to gain knowledge with their energy sources Increasing population has caused a major demand for energy independence and reliability. Non-renewable resources will eventually run out and cause energy prices to skyrocket, which will destroy the worlds infrastructure.

Investing in clean energy will have a beneficial impact on our economy through job creation, energy independence, and increased investing. This must be dealt with soon, because if it is not, it will only become an even bigger problem Free Essays words 1. New alternative energies will change into what the world will use to get their energy. They help create from none to barely any pollution for the environment unlike the resources the worlds been using to get energy The yearly energy and fuel consumption rates have risen dramatically within the last years.

This phenomenon is a direct result of globalization pressures, the international information network we call the Internet, and a population that seems to be hitting the dangerous upswing of the Malthusian curve.

There are many kinds of substitute sources of power that are modifying our life progressively, such as solar panel technology, breeze power, atomic power, tidal power, wave power etc.

To be able to use these substitute sources successfully, it is necessary to come up with some legitimate alternatives The use of solar energy can also save the depleting fossil fuels and can be sustained for future generations. Also it would take only around 0. Solar energy reduces the emission of greenhouse gases, like carbon dioxide, and also reduce the dependence on the fossil fuels Without the continuous supply of energy that most of us take for granted, things would quickly come to a stop.

We are dependent on energy for our very survival. Heating our homes, transportation, communication, health, even our daily food supply, which all depends on energy. But while energy delivers much that is good, it is also a primary factor, the primary factor. Which destroy our life systems.

Alternative energy

From smog, to acid rain, to climate change, to nuclear radiation, the effects of our current energy habits are fundamentally destructive, threatening our and all future generations What if the world ran out of the resources used to make these activities possible. What if heating your house was not a simple task that could be done by pressing a button. This could be the case if we continue to use nonrenewable energy resources. The article, Energy Resources states that the use of these resources "is increasing at an unprecedented rate due to the rapid industrialization of a number of formerly third world countries.

Powerful Essays words 5 pages Preview. This alternative source does not rely on the incineration of carbon substances to produce energy in contrast to the commonly used fossil fuels and therefore, does not aggravate the air and water pollution issues that the world is currently facing. Solar energy also has only a few detrimental effects to society and these can be easily eradicated by modern technology and strict regulation. During the energy production process, solar factories release toxic chemicals; however, these chemicals do not pose a threat because there are already solutions that can remedy this situation It has merely made more urgent the necessity of solving an existing one.

This increase resulted in an accelerated depletion of the resources of fossil fuels such as coal, oil, and natural gas See figure 2. For centuries, fossil fuel was, and still is the most conventional source for generating energy Term Papers words 4. The world, including the Philippines, is practically dependent on a dwindling non-renewable source of energy.

Today, experts are debating about and considering three options: Nuclear, Solar, or Wind Energy. Everyone has been accustomed to the bad image of nuclear energy as a result of the Chernobyl and Fukushima incidents above all others Few energy resources have been spoken with such notoriety by some and praised as the final energy solution by others than nuclear power.

However, the United States must increase its use of nuclear power in order to cover rising energy demand caused by the global energy crisis. In addition, nuclear power is and will be an important factor in combating atmospheric increases in CO2 and maintaining economic strength When the Middle East resolves its crises, oil prices fall along with the investment in geothermal energy Savage In the United States, geothermal energy has received the most interest due to the current unrest Savage When compared to , the funding had increased by nearly 40 times more Savage If the politics of that area were reorganized and we had not taken military action, Saddam Husein could have cut off his supply of oil to our country, shooting our prices to outrageous heights.

If we could lessen our dependency on such countries for oil, our country would be much better off. When a crisis hits the U. Free Essays words 5. Even though it is cheap, it is not renewable hence not an ideal source of energy. There is a plethora of renewable energy sources but why is wind energy superior to them all. Created by Charles F. Bush in at a company called Green Ohio Energy, to harnest the power of the wind and convert it into renewable energy. Wind energy can be accuired by utilizing wind turbines that rotate when wind passes through the blades of the turbine Another great reason to use green energy is it does not harm the environnment when making energy as much as other ways.

One of the best ways of creating green energy is through wind turbines. Wind turbines generate electricty through kinetic energy from the wind. When wind blows and catches on the blades they spin, which then makes a generater convert that into usable energy These fossil fuels are burnt in order to generate the energy required to complete various tasks. However, we are now realizing the problems that are created by using fossil fuels to generate energy. These problems are so great that they will force humans to find an alternative source of energy in order to avoid the inevitable disasters that lie ahead Free Essays words 2.

Many non-renewable energy sources are being innovated to make them become renewable. Three types of new renewable energy sources are mentioned in this research paper.

A nuclear power plant was being pushed too far and the cooling system was compromised resulting in a meltdown of the power plant It draws both of them in through separate tubes, and then puts them into separate chambers separated by a semi-permeable membrane. The term semi-permeable means that some things can go through it and others cannot go through it, for example the fresh water can pass through this semi-permeable membrane, but the salt water cannot. Since this is true, the fresh water goes into the salt-water chamber, and this causes the chamber to rise and create pressure when it is full, this pressure is then directed down a tube and into a turbine Using nuclear power as our energy source could be our solution to lowering global warming.

The nuclear waste could seep through the ground and contaminate our water which causes our marine animals to be contaminated. Not only do we currently use nuclear power to produce energy, we also use it as a weapon. Nuclear power uses uranium to power the plant because the heat to create the steam happens during fission Better Essays words 2 pages Preview. Biodiesel can be made by anyone with free time and dedication.

So after doing some research I have a rough idea of what biodiesel is and what its made of. Biodiesel is a alternative fuel that is used in diesel motors so people don't have to run just straight diesel fuel There are many other alternative power producing sources that can produce energy more efficiently and more safely than nuclear power plants can. Considering all the facts stated above, the question in our mind should be: if this energy source is as good as it is said, why is it not used worldwide.

The answer to this question is as simple as the following: the acquisition of this technology is too pricey. Thus, people often do not have enough money to afford the installation of solar panels. Therefore, to popularize and make the use of solar power easier for all, this technology should be developed in order to make it less expensive. It is what the professor Nathan S Term Papers words 3.

This problem is the need for alternative energy sources which can be converted into electricity because the main energy source currently used is coal and the coal deposits will not last forever. The main alternative energy sources that many countries are currently researching are wind, solar, hydro and nuclear.

But there is another source of energy that is heavily debated to see whether the pros outweigh the cons. This energy source is natural gas. The main reason for the heavy debate is not the energy source but rather the mining of the energy source through the process of hydraulic fracturing In addition to supporting life water has been used for centuries to power saw mills that would generate electricity.

Like many other water sources, water has some advantages and disadvantages. There have been intense debates on whether this source of energy is worth using up the water from the lakes and rivers, something that is important to protect the animals and plants.

A typical hydro plant is a system with three parts: an electric plant where the electricity is produced; a dam that can be opened or closed to control water flow; and a reservoir where the water can be stored Wave power plants have a simple, yet practical way of harnessing the endless energy that ocean waves provide. Although the development of harnessing this renewable source of energy is still in its infancy, many predict that this underdog of a resource could be used worldwide in the near future.

Wave power plants are able to harness renewable energy by using the ocean's waves. There are several different types of wave power plants, but most behave in a similar way Coal Power Nuclear power and coal are two of the main sources of electricity used in the United States today. Yet they are also the most feared and misunderstood.

While both have negative connotations, they both are clearly still doing the job better than other alternative energy. Nuclear power is not readily feared for the result it will have on the environment although it should be. Used fuel assemblies are kept on site for at least seven years usually stored in onsite ponds With the continuous depletion of fossil fuels, there is an urgent need for alternate forms of energy, in particular technologies that are renewable, sustainable, and inexpensive.


Solar cells have been considered a promising potential solution to this problem, but issues with conventional photovoltaic cells based on crystalline materials include high manufacturing cost, poor durability, and limited versatility. Currently, only 0. Strong Essays words 3. At feet 30 meters or more aboveground, they can take advantage of the faster and less turbulent wind.

Current Biology

Turbines catch the wind's energy with their propeller-like blades. Usually, two or three blades are mounted on a shaft to form a rotor. Around the world utility services are offering wind-generated electricity at a premium of 2 to 3 cents per kWh. These resources are non-renewable.

However, newer technology has allowed us to use renewable sources such as the sun or wind. These sources for practical purposes will last forever. People should use renewable energy because they are sustainable and environmentally friendly. However, there are high economic costs associated to switching to renewable energy and renewable sources are not as reliable as conventional fossil fuels This could lead to international insecurity as the need for the resource might trigger conflicts, leading to increase tensions among our nation and others.

The need for this resource affects a country's international security, as countries going for the same resource might go to war over it and countries who have it will readily guard it. Another part of fossil fuel that is negative aspect is how fossil duel is contributing in climate changes.
