Conspicuous consumption

Heating, ventilation, and air conditioning (HVAC) systems in commercial buildings are responsible for consuming more than 40 percent of the total energy usage. Keeping it running properly and at peak efficiency is one of the important steps in energy management. A good system maintenance is more than just controlling energy usage. Besides people comfort, today's buildings depend on HVAC systems for other important reasons too. For example, most telecommunication systems need specific…

It is efficient as in one small plant produces enough energy to run a about 100 homes for about a 1000 year without refueling. Now imagine this times a few hundreds. if all the world used nuclear plants for eighty percent of their energy consumption instead of fossil fuels and natural gasses the world will produce energy efficiently and in massive amounts, which will benefit us globally, socially, economically, and lastly and most importantly Environmentally. It reduces carbon dioxide production…

Nowadays, most daily activities of human beings rely on fossil fuels heavily such as transportation, lighting, heating and communication. However, many scientists forecast that fossil fuel will be running out in the next century. Therefore, before its exhaustion, it is necessary to develop an alternative energy. Among all renewable energies, we will discuss the pros and cons of nuclear energy, solar energy and wind energy. To begin with, nuclear energy has several major advantages. Not only a…

Energy is one of the most fundamental thing in all kind of life on earth. It allows people to travel across the globe, it provides electricity to our homes, it is critical to almost all the basic human activities. This fact makes the energy sector one of the most important sectors that gives input to many other sectors (Bozkurt, 2010). As a matter of fact, electricity changes the way people live and see the world and without it everything would be different. Apart from that, economical…

Thermoelectric characteristics of bulk and ultrathin Ge-on-insulator substrates fabricated by direct wafer-bonding 5.1 INTRODUCTION Thermoelectric materials have been attracted considerable attention due to their ability to capture waste heat and to convert to useful electrical energy. However, their conversion efficiency is not sufficient for a practical use. The theoretical power-generator efficiency increases monotonously with increasing the figure-of-merit Z of thermoelectric materials which…

1.1 Overview Electric motors are the majority of the industry prime movers. Induction motor is the most popular ones for their reliability and simplicity of construction .although induction motors are reliable they are subjected to some mode of failures. These failures may be inherent to the machine itself or due to operating conditions. The origins of inherent failures are due to mechanical or electrical forces acting in the machine enclosure. Researchers have studied a variety of machine…

Physics Article: Hydroelectric Energy What is hydroelectric Energy? Hydroelectricity is a term that is referred to as generating electricity by Hydropower. Hydropower is a movement of water that flows downstream to create Kinetic Energy, which can be converted into electricity. Hydroelectric plants convert the energy into electricity by forcing water. The hydropower produces electric power through the use of flowing water or the gravitational force. Hydroelectricity is a renewable…

Introduction: With the constant rise for global energy, there is a huge demand for environmentally clean and cheap energy sources. Now, for many years power generated by nuclear power plants has been a reliable source for energy but the current amount of uranium, which is the fuel will satisfy the energy requirements for the next 200 years. Also, the nuclear reactors are not very efficient as not all of the uranium mined is being used to generate power. In this essay, I will discuss an alternate…

Introduction: Energy is an important factor for development of country’s economy and for most part this energy is produced from non-renewable sources. For transforming from conventional to green energy some strategies and policies have to be implemented, proper framework must be employed such that the existing constraints and barriers for renewable energy technologies are reduced. It is necessary to create conditions for increased investments in a transition to green economy. Pursuing clean…

James Morrison Dr. Birdsong Political Science 10/26/2014 Alternative Energy Introduction Renewable energy is also referred to as alternative energy. This is generally, power whose source does not run out. Unlike fossil fuels, it causes no pollution. The energy leaves no residues that would otherwise cause harm. Alternative energy is a common term, used to contrast this form of energy from the traditional sources of energy such as coal power and natural gas as well as oil power. The traditional…
