Energy, Sustainability and Renewability - Assignment Example

Various issues will be discussed in this assignment related to energy and its other variables. KEY TERMINOLIGIES For better understanding of this report some key terminologies have to be discussed in detail. These terms are the essence of this paper and cannot be comprehended without excessive research from different books and journals related to physics. Energy Although energy has been described in the introductory paragraph, a further analysis will be produced here. As described before that the ability of a system to do work on another system is known as energy.

Coming towards the sub-division or the types of energy present in the language of physics. Energy can be divided into mechanical, solar, thermal, chemical, electrical, electromagnetic and nuclear energy. Mechanical energy is further broken down into two very important categories, potential and kinetic energy. Potential energy is the form of energy stored in a body for e.g. a fully stretched elastic band and kinetic energy is the one when a body is motion for e.g. the same elastic band when being released.

Sustainable Energy The fact that energy is utilized by burning or disfiguring other natural resources brings about the change in thinking of man, can we provide energy otherwise? The answer to this lies in the definition of sustainable energy. It is the provision of energy that meets the need without compromising the ability to generate energy in the future (Smith, 1998). Several factors go into making energy sustainable. The first is whether or not the current use of the energy is something which could potentially persist into the future, which leads many forms of renewable energy to qualify as sustainable.

Therefore renewable and sustainable can be termed as in-lieu terminologies. Some of the renewable energy sources are hydroelectricity, solar energy, wind energy, wave power, geothermal energy, bio-energy, and tidal power. Examples Some of the examples of sustainable/renewable will be discussed in this report to better understand the various benefits and downsides of this form of energy. Hydroelectricity is the first term that will be discussed. It is one of the most used alternate energy being used in the modern world today.

The flow of water in the river is used to turn turbines which in turn produce massive amount of electricity. Then comes wind energy which is the most blossoming alternate energy source in the commercial market is the ability to produce energy with the help of wind. Wind energy has had a huge impact in the energy industries. Wind farms have been set up in various windy cities of the world top produce large amount of electricity. The output power produced has been increasing by the day. The fact is clearly shown by the figure (Maggie, 2008) Issues with Renewable Energy Various questions have been raised with the alternate energy process.

Although that the new renewable sources are cheap and effective, still many organizations and researches show that this form of energy production is more harm, since cost effectiveness is not the only issue at hand. Even before the low cost electricity is produced the problem which arises is that the setup of such plants which produce cheap energy, be it a dam or a wind city. Solar panels cost way more than burning fossil fuel and setting millions of panels for sustained energy providence is also a very costly factor.

The problem is just not cost effective. Natural and environmental damages have huge costs
