Energy - 1130 Words

Electricity is produced by converting energy from one form to electricity. The process used may be a direct conversion process, where the energy source is converted directly to electricity. An example of this is solar photovoltaic cells, which converts the energy found in solar radiation directly to electricity. An indirect conversion process consists of converting energy from one form, to an intermediate form, to electricity. Coal-fired generating plants are an example of the indirect process, as the chemical energy released as heat by burning the coal is changed to rotating kinetic energy by the steam turbine, and then the rotating kinetic energy is converted to electricity. The majority of the electricity today is produced through an†¦show more content†¦The problem with this type of power is that turbines destroy natural scenic views and generate noise pollution. Hydroelectricity is power derived from the energy of failing water which can be harnessed and used. Since water is about 800 times denser than air, even a slow flowing stream of water, can yield considerable amounts of energy. Once a hydro power plant is constructed, the project produces no direct waste. However, the number of water sources limits the development of hydroelectric power stations, which is why underwater tide turbines within the oceans may be another great alternative power source to harness power from the natural flow of water. Fossil fuels are currently pretty cheap, as are the methods of generating energy from them. With our existing distribution networks, we can get fossil fuels of all kinds all over the world. That makes it easy to use them, no matter where you are. Many alternative fuels remain expensive, hard to distribute, difficult to get energy from and hard to access, making the switch over extremely difficult. Power stations that make use of fossil fuel can be constructed in almost any location. This is possible as long as large quantities of fuel can be easily brought to the power plants. Transporting oil and gas to the power stations can be made through the use of pipes making it an easy task. When coal is used in power plants, they are very cost effective. Coal is also in abundant supply. A major advantage of fossil fuels isShow MoreRelatedEnergy And Energy Of Energy1140 Words   |  5 PagesScientifically, energy is defined as the ability to do work. While there are many forms of energy, the y can be grouped into two categories:Potential energy, or stored energy; and Kinetic energy, or energy is a form of potential energy and it is possessed by things such as food, fuels, and batteries. Energy is the ability to cause changes in matter. It can exist in many different forms. Energy can change from one form to another. There are six forms of energy: mechanical, chemical, electrical, lightRead MoreEnergy Of Energy : Energy1954 Words   |  8 PagesEnergy: Energy is the ability to work. The definition of work is every time a force is exerted on something through a distance. An in depth explanation would define doing work as mechanical energy. An example of one of the many different types of energy is when you kick a soccer ball you are using the maximum amount of kinetic energy and the least amount of potential energy. The energy formula is Power multiplied by time which is then divided by joules (a way of measuring energy) which is watts multipliedRead MoreThe Energy Of Energy Usage1129 Words   |  5 Pageshigh-end consumer in terms of energy usage. According to U.S. Dept. of Energy, there are more than 40,000 distillation columns in North America and they consume 40% of the total energy used to operate plants in chemical industries [1]. As a result, researchers have focused their efforts towards developing distillation columns that are more compact, utilize compressors to recirculate latent heat and possess more effective separation technology in order to reduce energy consumption. The principal topicsRead MoreSolar Energy Definition, Alternative Energy, Renewable Energy948 Words   |  4 PagesTitle: Solar Energy Definition Meta Tags: solar energy definition, solar panels definition, solar power definition, alternative energy, solar energy power Meta Description: Learn how solar panels harness the power of the sun to create a clean and renewable form of electricity that can save you money on energy costs. Simply stated, the definition of solar energy is energy that is created by the sun. In the context of modern usage, solar energy may refer to technology that converts radiationRead MoreThe Energy Of Solar Energy1462 Words   |  6 PagesInstitute for Energy Research and the U.S. Energy Information Administration, solar energy makes up only 0.5% of total energy consumption in the United States, and over 65% of consumed energy is natural gas and petroleum. (2016) These statistics show that nearly two-thirds of the energy the United States uses is not only non-renewable but the processess of harnessing it also causes pollution. Solar Energy is energy that is transferred through solar radiation in the form of electromagnetic energy. In theRead MoreThe Gap Between Energy Consumption And Energy Generation1718 Words   |  7 PagesCHAPTER 1: INTRODUCTION AND BACKGROUND Background The gap between energy consumption and energy generation is gradually increasing and has become a significant problem for both domestic and industrial applications. Furthermore, conventional energy sources, like fossil fuels, are not fulfilling the energy needs of the developing world. And, although they are still major energy sources for both the industrial and domestic sectors of the world s economy, they are also responsible for many problemRead MoreThe Energy Of Renewable Energy Essay2304 Words   |  10 Pagesproduce energy. Renewable energy systems have experienced unimaginable advancements in recent years to make them more efficient, but utilities still struggle with the storage of this energy for practical use. Different types of renewable energy are currently stored in multiple ways, which contributes to discrepancies among the comparative efficiencies of various sources of energy in different areas and situations. This paper will discuss how several major renewable syst ems store energy, and whatRead MoreNuclear Energy : Renewable Energy727 Words   |  3 Pages32% of our energy for electricity? Energy makes lots of things work like machines. There is not just one word for energy, another word is power. Two of the main types of energy is renewable, and nonrenewable. Renewable energy is energy used over and over again. Renewable energy will not run out. Some examples of renewable energy is solar energy, hydro energy, and wind energy. Non renewable is energy is that will eventually run out. Some examples of non renewable energy are nuclear energy, coal, andRead MoreEnergy Of Energy And Energy Consumption931 Words   |  4 PagesEnergy Preliminary Evaluation The main aim of the energy category is to reduce energy consumption. Currently, the main source for energy is fossil fuels. During 2011, around 95% of energy used in Australia came from fossil fuels (BREE (Bureau of Resources and Energy Economics), 2013), making the energy sector the most important Green House Gases (GHG) source in the country. Energy used in buildings accounts for around 20% of the total emissions (ABCB, 2014) therefore, their reduction will make aRead MoreRenewable Energy : The Energy926 Words   |  4 PagesRenewable Energy Is it possible to live without energy?
