Renewable Sources Of Energy

During the 1970s, energy conservation was a popular idea—the energy “crisis” forced governments to encourage the public to use energy wisely, to become less wasteful and to think about energy consumption. Government programs emerged, research into alternative energy sources was financed and individuals tried to make a difference. This will look at the advantages of renewable energies rather than what has been submitted so far. Introduction The utilization of renewable energy is no longer new to man because a century ago, wood already supplied more than 90 percent of man’s energy needs. However, because of the convenience and low prices of fossil fuels, the use of wood no longer became popular. The consumption from these sources summed up to ….

Ethical Energy

Over the past years, there has been increased exploitation of the natural energy resources especially crude oil and therefore increasing the carbon gas emission into the atmosphere and destruction of the environment. Most of the developed countries and emerging economies are the major consumers of oil and the rate of gas emission is very high in such countries making them to experience slightly higher global warming temperature compared to global average. The United States and Chinese per capita carbon dioxide emissions are to top most in the world. The effects of carbon fuel are destructive and as a result there has been a fruitless effort to invest in alternative energy, the green energy which is more ethical and environmental friendly….

Functioning Of Body Systems

What is energy? Energy can make changes possible. We use it for our every day lives, it helps to move cars over road and boats over water. Energy is also used to allow our bodies to grow, keep warm and help our minds think. Scientific define energy as the capacity to do work. Energy cannot be destroyed or created, only transported from one source to another. Forms of energy • Potential Energy: Potential is the stored energy of position and the energy of position- gravitational energy. When an object is displaced from its original position and there is energy pulling it back to that position, this works with potential energy. This is when a moving object no longer has kinetic…

Work and Energy

Energy, the ability or capacity to do work, is found in various forms. It can be in the form of light that is needed by plants to growth, electrical energy to light up a house, a nuclear power produced by some power plants, heat produced by the sun, or mechanical energy produced by different machines. The law of conservation of energy states that energy can neither be created nor destroyed but can only be transformed from one form to another. The transformation of energy relates to the work being done by forces that exerting on an object. A conservative force, also called potential energy such as gravitational force and spring force, can be stored. On the other hand, a force…

Three Energy System That Are Responsible to the Production of Atp

Glycolytic System Glycolytic system is the breaking down of glucose or liver glycogen to pyruvic acid via glycolytic enzymes. This system only uses carbohydrate as the main source of fuel and occurs in the sarcoplasm of the muscle cells. The glycolysis system can rapidly produce ATP without use oxygen. Glycogen is synthesized from glucose by a process called glycogenesis and stored in the liver or in muscle until needed. Before either glucose or glycogen can be used to generate energy, they must be converted to a compound called glucose-6-phosphate. The conversion of a molecule of glucose requires 1mole of ATP. mole of glucose produces 2ATPs or 1 mole of glycogen produces 3ATPs. Glycolitic system provides energy for high intensity exercise…

Energy Exam

1. To cut down on energy usage, the main priority in the house is to keep it self-insulated. Covering the attic and floors with insulation will help maintain heat during the winter, which is one of the largest energy burners. Many times, access to floors can be found in the basement in order to line insulation. In conjunction with this, any exterior drafts should be covered with caulk and the doors should have draft guards. Have plugs connected to a power strip and turned off when not in use. This will limit the flow of power. Using florescent light bulbs will help out with efficiency as well, especially in winter. During summertime, candles can be utilized since dusk occurs much…

A Better Future with Green Technology

We live in the 21st century which has been called the “century of the environment”. Our nation’s leaders and individual citizens are coming to an understanding that we can not assume any longer that problems such as pollution, climate changes and the dwindling amount of natural resources can be put off for a future generation to deal with (Green Technology, 2010). There are many uses and reasons for green technology. However, with the use of green technology we can have a healthier, cleaner and possibly longer future. In this paper, I will be discussing just a few of those many uses. The term technology refers to the application of knowledge for a practical purpose. Now the field of green technology…

Usage and Production of Energy

Energy, or in simple words electricity, is the main source of power on which every process of our society relies. After industrialization the usage of electricity for economic growth was as important as oxygen is for life. Every sector, even agriculture, began to require usage of different forms to electricity to keep up with the changes in trends and increases in demand levels. Energy is said to be produced from various “natural resources” such as coal, water, wind, oil, solar, as well as nuclear. Electricity is generated by the “heat or motion” of the sources mentioned above. It is said generation of electricity by the usage of nuclear power is one of the most “cleanest and environmentally friendly ways” of…

Describe two initiatives established by the Clean Air Act Amendments of 1990 that have enhanced the nation’s demand for ethanol? One Clean Air Act Amendment of 1990 required the use of oxygenates (such as ethanol) to be used in reformulated gasoline. Another Amendment required that reformulated gasoline be required in regions that violate standards set forth by the Act. This was implemented in 9 specific areas year-round, and wintertime only months in 39 more areas. 2. What is winter oxygenated fuel and what is the benefit to the environment? Oxygenates are added to gasoline in order to reduce carbon monoxide,…

Chinese interest on Central Asian Energy Resources

There are several prospective predictions that can rationally be made concerning the future of the strategies and pipelines such as the China-Kazakhstan oil/gas pipeline. This must however appreciate the difficulties involved in efforts to provide reliable predictions, but from the observed disadvantages and advantages of these pipelines, we can apparently assume that existing pipelines will be continuously used to transport gas and oil. It can also be assumed that pipelines under construction will continue and be online sooner or later. Furthermore, it is known certainly that Central Asian gas export routes are facing more difficulties than those experienced in the oil routes. This is particularly so in regard to the Kazakh and Turkmen gas which cannot currently be brought to…

Xing Zhong,[a] Hua Zhang,[b] Yuan Liu,[b] Jingwei Bai,[b] Lei Liao,[a] Yu Huang,[b] and Xiangfeng Duan*[a] The ever-increasing demand for portable power sources has motivated considerable research efforts towards a variety of power and energy systems.[1–9] The metal–air battery, using the reduction of oxygen from the atmosphere as cathode reaction, is known for its high energy density.[10] The zinc–air battery, being the first commercialized metal–air battery, has received significant attention since the 1960s.[11–15] More recently, there has been renewed interest in this battery for application in electric vehicles.[16] However, the zinc–air battery can provide a practical energy density of only 470 Wh kgÀ1, from a theoretical value of 1370 Wh kgÀ1.[17] The aluminum–air battery has a high theoretical energy density (8100…

Product Review for Nike Fuel Band

I’m a number junkie, I love knowing exactly how many calories I’m taking in, my macronutrient ratios and I’d always wanted to know how many calories I burn on a daily basis. To feed my number addiction I typically weigh my food and prepare an entire days food in one sitting. With that said, being able to track my energy expenditure was very appealing to me. I came across an energy tracking product called Nike Fuel Band. Being able to get a rough idea of how many calories I burn throughout the day was exactly what a fitness nerd like me wanted to know. After using this product for three weeks, I am blown away by the total package of…

Black Body Radiation

When solid objects are heated, they emit radiation. At normal temperature, we are not aware of this radiation because the intensity is low. At higher temperatures, there is sufficient infrared radiation that we can feel the “heat” if we are close to them. At even higher temperature, the objects actually glow, like the heating element of toaster or red-hot electric stove burner. Since they are radiating energy, there must be a rate at which they are radiating. They may radiate 10 Joules per second or maybe 100 Joules per second. This rate is related to the temperature of the object. It’s obvious that higher the temperature, they higher will be the rate of radiation. What may not be obvious is…

What are the forms of energy

Energy comes in two basic forms: potential and kinetic. Potential Energy – is any type of stored energy; it is not shown through movement. Potential energy can be chemical, nuclear, gravitational, or mechanical. -Kinetic energy is the work required to accelerate an object to a given speed. -A function of the position of an object within a field. * Chemical energy is stored in the bonds between atoms. This stored energy is released and absorbed when bonds are broken and new bonds are formed – chemical reactions. * Nuclear energy is the stored potential of the nucleus, or center, of an individual atom. Most atoms are stable on Earth; they retain their identities as particular elements, like hydrogen, helium, iron,…

Fluent Melting and Solidification

8.1 Overview of Phase Change Modeling in FLUENT FLUENT can be used to solve uid ow problems involving phase change taking place at one temperature e.g., in pure metals or over a range of temperature e.g., in binary alloys. Instead of explicitly tracking the liquid-solid front as the phase change occurs, which requires a moving mesh methodology, an enthalpy-porosity formulation is used where the ow and enthalpy equations are solved with extra source terms on the xed grid. Marangoni shear, due to the variation of surface tension with temperature, is important in many industrial uid ow situations involving phase change. The phase change model in FLUENT provides the ability to specify the Marangoni gradient at a sloping surface, as well…

From Fossil Fuels to Renewable Energy

The gas pump. As of late, it has been the bane of drivers everywhere. With the prices of crude oil skyrocketing combined with the prices at the pump and nearly everywhere else, many people are looking toward renewable energy sources to supplement or replace the use of fossil fuels. This interest in renewable resources has generated new energy policies around the world, has spawned new energy technology and has produced ideas on a different way of living. Adding to the interest is the awareness on humanity’s impact on our environment, there is so much interest that the United States and many other countries have started to explore the option of producing power by the cleanest sources possible. However, it may…

Energy Conservation

Abstract: The gap between supply and demand of energy is continuously increasing despite huge outlay for energy sector since independence. Further the brining of fossil fuel is resulting in greenhouse gases which are detrimental to the environment.

Energy Development and Electricity Usage

Electricity consumption is something we do out of habit and unintentionally. We develop our habits based on our needs, hobbies, works, entertainment and enjoyments. We never really aware of how much we use daily and how much the source of energy is left in this world. We are named as screen generation, it means we all depending on electronic stuffs to complete and help us out in our daily life. We use air-con, television, refrigerator, fan, lamps, iron more over we use electricity to charge our gadgets those we probably have more than one like phone, laptop, tablet etc. We never really care about where the energy came from and are we wasting it? Main energy source is fossil fuels…

Sip for Wind Turbines

A wind turbine is a device that converts kinetic energy from the wind, also called wind energy, into mechanical energy in a process known as wind power. If the mechanical energy is used to produce electricity, the device may be called a wind turbine or wind power plant. If the mechanical energy is used to drive machinery, such as for grinding grain or pumping water, the device is called a windmill or wind pump. Similarly, it may be referred to as a wind charger when used for charging batteries. The result of over a millennium of windmill development and modern engineering, today’s wind turbines are manufactured in a wide range of vertical and horizontal axis types. The smallest turbines are…

The Beach Reflection

A new sunny day has just begun. The beach is silent, but only for a while. Very soon crowds of people will flood on to the beach. The bright, burning ball blinds and rises like a sunflower on the distant horizons. The subtle sea sparkles preciously as it strolls up against the shore spilling the previous day’s remains. Crashing against the shore, small waves flash the night’s debris onto the beach. Untouched golden sand, so soft and smooth, glistens; reflecting the sun’s rays. A soothing, light and refreshing sea breeze rustles through the first visitors of the beach. The whole place itself shows a wide range of colours that reflect on the surface like a dancing peacock demonstrating its feathers….
