The law of conservation of energy

Energy of a system refers to the capacity of the system to perform work. The law of conservation of energy refers that energy can be neither created nor destroyed. The law of conservation of energy also stated that the total amount of energy remain constant because it changes one to another. This law is also helpful in developing better understanding about the world. According to MBA degree assignment help experts, this law is also helpful in understanding of nature and human locomotion. The conservation law of energy is a physical principle that identifies some quantity that does not change with time (Holton & Brush, 2001).

This law applies on wide varieties of situations. For example, for production and use of electricity,

 

most of the electricity plant, a fossil fuel is burned in order to produce heat energy that turns water to steam. The energy of steam turns the blades of turbine in order to produce mechanical energy. In this, the turbine provides power to generators that produce electrical energy. In homes, electrical energy is used to provide heat energy, light energy, sound energy and mechanical energy. In this, the energy changes its form but the amount of energy remains the same in a closed system (Whitman, Johnson & Tomczyk, 2005).

Pros and Cons of Various Energies

As per case study assignment help experts, the pros and cons of energy are as follows:

Fossil Fuel: The major advantage of Fossil fuel is that this type of fuel has good availability in the market. It has also simple combustion process that easily or directly heat and generate electricity. This type of fuel is also inexpensive that provide the advantages for the customers to easily purchase from the market. Fossil fuel includes oil, natural gas and coal that are widely and easily distributed all over the world with the help of rail and sea tankers. On the other hand, fossil fuel also has some disadvantages such as this type of fuel is a contributor of global warming. It is also identified that this fuel is also a cause of acid rain in the environment because it produces the carbon dioxide. In fossil fuel, used oil is very difficult to recycle and causing a lot of pollution in the environment (Morgan, 2007).

Nuclear Energy: Nuclear energy has produced very less amount of pollution as compare with the fossil fuel. To produce huge amount of nuclear energy, a very less amount of raw material is required. Nuclear energy produces cheap electricity and gains other benefits to the power stations. To produce energy, less amount is required that helps the power stations to easily transport the nuclear energy from one place to another. In this type of energy, the nuclear waste is also small that provide a very reliable source of energy. On the other hand, some disadvantages of nuclear energy such as the storage and management of nuclear energy is dangerous because it produces high level of radioactive wastage. Nuclear waste creates thermal pollution that may damage the environment. There is a need of huge capital investment and advance technology in order to start a nuclear plant (McLeish, 2007).

Solar Energy: It is a renewable resource because it generates the energy from the sun. The major advantage of solar energy is that it helps the environment because it produce energy direct from sun that provide no harm to environment by putting green house gasses, polluted water, air or land. It is cheap and easy to purchase for the customers because this energy use cheap technology to produce energy that have long life. Disadvantages also related to the high initial cost of the equipments. The technology is also a costly alternative as comparison to the fossil fuel. This energy is also required large installation area in order to provide sufficient energy (Thomas, 2007).

Wind Power: This energy produces less green house gasses or other pollutants. The wind turbines can be very tall and takes up a very small plot of land that means people can use the blow land for their use. Remote areas can also use wind power for their own supply of electricity. Some disadvantages such as wind turbines does not produce same amount of electricity all the time. Wind turbines generate high level of noise in the environment (Spilsbury & Spilsbury, 2007).

Water Power: In water power, once the dam is constructed, electricity can be produced at the same rate. Electricity can be generated for many years because dams are designed for many years. Disadvantages such as building a dam is very expensive, present serious geological damage and blocking the progress of a river in one country to another, etc. (Spilsbury & Spilsbury, 2007).

Bioconversion: It is an eco friendly process that is beneficial for the environment. The bioconversion process produces isobutene in the gas form that is a cheaper and more efficient for the companies. Disadvantages are related to the dilution of products, sensitive to environmental extremes of temperature, pH and negative regulation of biocatalyst, etc. (Nielsen, 2001).

Provision of Energy Policy Act, 2005

In August 2005, the federal government signed the Energy Policy Act, 2005. This has two major provisions such as “manufacture and consumer tax incentives for advance energy saving technologies and practices and minimum energy efficiency standard on 16 products”. In the act, the provision of tax incentives provides more than $2 billion for advance energy saving technologies and practices. In this college study assignment help, utilities and other agencies should implement energy saving programs to complement new tax incentives such as new homes, new commercial buildings, appliances, heating, air conditioning and water heating equipments. According to the provision, this act also adopts standards on 16 products and provides the directions to the US department of energy to revise some rules of these standards on several other products (Nadel, 2005).
