The Great Transition: Shifting from Fossil Fuels to Solar and Nuclear Energy is a book that presents a definitively anti-fossil fuels stance on renewable energy written by Lester Brown, a lauded environmental scientist with more than 50 years of experience in the field of renewable energy who is certainly qualified to write about the topic. In the first half of the book, he discusses why society should phase out usage of fossil fuels, especially coal, as quickly as possible in order to prevent…

There are many pros and cons to having nuclear power plants in a certain vicinity. Many of the pros talk about low pollution, low operating cost, reliability, high energy density, and more. Many of the cons talk about environmental impact, radioactive waste disposal, high cost, nuclear accidents, and more. In an area where the nuclear power plant is old, they should close it down and make the site environmentally safe for the next 100 years instead of making some major repairs. If the nuclear…

system maintenance could be the deciding factor between keeping a business running and having to shut it down. The following five considerations in commercial HVAC repair and maintenance could help you in keeping your heating and cooling system function properly round the year. 1. Schedule Your HVAC Maintenance The HVAC industry recommends that heating and cooling systems be serviced twice a year, preferably in spring and fall. These two seasons mark the transition from using air…

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…

Figure 5.9 shows the measured Seebeck coefficient Sexpt of p-type Si, Ge and polycrystalline Si0.68Ge0.32 as a function of carrier concentration. The dotted, dash-dotted and the solid line exemplifies the theoretical S values calculated by considering only the carrier transport for p-type Ge, Si and Si0.68Ge0.32, respectively. The theoretical Seebeck coefficient Se…

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…
