Energy and Its Sources
Energy is an important element in daily life since it used for many activities like moving vehicles, promoting growth of the human body, and enabling humans to think. However, energy can be found in various forms like sound, heat, motion, and light though they are classified into kinetic and potential energy. While kinetic energy is the motion of substances, waves, objects, molecules, and atoms; potential energy is gravitational or stored energy. Some major examples of kinetic energy include thermal, radiant, electrical, motion, and sound while potential energy includes nuclear and chemical energy.
Converting Energy from One Form to Another:
Based on the Law of Conservation of Energy, no energy can be lost as energy is transformed or converted from one form to another ("Chapter 2 -- Forms of Energy," 2012). This is mainly because the total amount of energy used in the conversion process must be equivalent to the total amount of produced energy. During this process, some energy is usually transformed into undesired form, which is commonly known as wasted energy. Similar to the processes involved in the conversion of coal into electrical energy, most energy conversion processes needs several steps. As compared to other conversion processes, the energy wasted in every step while converting coal to electrical energy makes the entire process less efficient. In this case, the amount of electricity produced is usually less than the amount used in burning coal.
Since there are various forms of energy, there are also different types of energy conversions such as mechanical, chemical, and electrical energy conversions ("Energy Conversions," n.d.). However, there are three basic ways with which energy can be converted from one form to another. First, energy can be converted through the action of forces including gravitational, frictional, and electric and magnetic force fields. Under gravitational forces, the potential energy of an object...
Energy is an essential force powering society, industry and in the end our everyday lives. Generally, energy sources can be classified as non-renewable and renewable sources. Non-renewable energy sources are those that can not be replenished or made again in a short period of time. Renewable energy sources on the other hand can be replenished in a short period of time (Energy sources, 2011). There are three main sources of energy
It is clear that if we as a species are to survive the 21st century and beyond, we must concentrate on changing our approach to the environment by reducing our carbon "footprint" and exploring the idea of renewable energy sources that will be appropriate for a growing global population. The Turning Point -- Transition to Renewable Energy -- the bleak reality is that the age of oil has dominated global
Energy Sources Energy is a mysterious force that appears to propel everyone and everything within the known constructs of the universe. All things both require and expend energy in all types of forms and systems. The purpose of this paper is to examine my own personal energy use to determine the extent, sources and destinations of this practice. This essay will include the different forms of energy I consume and expend
3%, which is significantly less than what is being demanded. Solar energy that causes less pollution than coal-based energy is not used as often as we should because it cannot be created with as much ease as the latter source. In order to translate solar power into electricity, greater power generation prowess is to be utilized. This is what has led to decreased use of renewable sources. Everywhere we see, the
Energy and World Economy Energy being a corner stone of the current industrial economy, it does offer an indispensable component for approximately the entire human activities. It offers services for food preparation as well as lighting, physical condition, storage, edification, granite mining, and industrial production in addition to transportation. Current energy services are with no doubt influential train of money-making as well as social growth, moreover no nation has contained the
Energy Drawbacks Because every energy-producing source has some drawbacks and negative issues, it is important for society to choose wisely when it comes to developing electrical generating sources. This paper reviews those issues. Wind Energy: there are many advantages to wind energy, including: a) it is non-polluting (no fossil fuels are burned in the process); b) less space is used than by building a big power station (and windmills can be built
