Essays on Energy

“ The year 2017 will be remembered as a significant one for defining India’s mobility architecture. India has seized its moment to announce big plans for finding next-generation ransport solutions. To the dismay of many automobile manufacturers sitting on a huge inventory of BS III...

What is PV solar power? You have heard the term, but you are unsure as to its meaning. You are vaguely aware that solar power has something to do with making energy from sunlight. But what is PV solar power? Is it different from other...

Introduction In the last few years, a range of energy-storage device applications has expanded from portable electronics to large-scale energy storage systems, including renewable energy storage and electric transportation [1,2]. To fulfill the energy and power density requirements for energy applications, many researchers have given...

In this study, the performance of an ohmic concentration system was analyzed based on the second law of thermodynamics. The influence of salt content (0-2% w/w), voltage gradient (5-11 V/cm) and electrode type (316L St, Al, and Br) were evaluated on the exergy aspects. Nowadays...

Over 65% of our power comes from fossil fuels like coal and oil and another 13% is nuclear power but very little down to lower than 1% and as high as the 7% mark, are the renewable power plants. Geothermal power is about around the...

Increasing energy needs and decreasing conventional energy sources put more focus on the renewable energy sources in general and solar energy in particular. Generation of electrical energy from solar energy needs the application of photovoltaic (PV) principles. Hence, PV cells have become most important component...

When it comes to healing, there are many tools and assets at our dumping. But there are few tools and assets that can line up your entire body with healing that works. It’s called energy healing, and the easiest way to have all of your...

We all know that Momentum is the product of the mass and the velocity of an object (Momentum = mass x velocity). Therefore, in shorthandnotation, Momentum= mv. A moving object can have a large momentum when either it mass or velocity is large or both...

Green energy comes from natural sources such as sunlight, wind, water and, biogas. These energy resources are renewable, meaning they’re naturally replenished. They are the safe way to produce energy that will not harm the world and the atmosphere. One of the technology trends making...

Electrical resistivity is a fundamental property that quantifies how strongly a given material opposes. Resistivity is measured by ohmsO. Electrons often encounter semi or non-conductive materials which causes resistance. A low resistivity indicates a material that readily allows the flow of electric current. Electrical conductivity...

The European Union Strategy bases on past experiences and incorporates actions that must be taken to face emerging challenges. It has been developed thanks to extensive consultations with the public and EU institutions. The 2020 strategy sets out steps which need to be taken to...

Shore A hardness The hardness of materials is the resistance to surface indentation. The test of NR-hardness is the test that investigates the reversible deformation of the material when the force is applied to the NR surface or. As it was expected, the hardness of...

I’ve been really interested in renewable and sustainable energy sources for a while. While there are many sustainable, renewable energy sources that can be used on a large scale and sold to consumers, I will discuss smaller scale systems that can be implemented within an...

3Energy Renewable (Pty) Ltd is the South African branch of 3Energy GmbH, a German facility management company with a track record of more than 15 years in the operation and management of wind and solar photovoltaic (PV) assets in Europe. 3Energy can operate in all...

1. ABSTRACT In this study, phones, wearable/portable devices, detectors that detect temperature and human motion are integrated as smart sensors to reduce the amount of energy used for air conditioning and ventilation. Advanced Smart sensors get input feedback from mobile phones, smart gadgets and portable...

Energy consumption is inevitable for human existence. There are various reasons for the search of an alternative fuel that is technically feasible, environmentally acceptable, economically competitive, and readily available. The first primary reason is the increasing demand for fossil fuels in all sections of human...

A Thermal Power Plant converts the heat energy of coal into electrical energy. Coal is burnt in a boiler which converts water into steam. The expansion of steam in turbine produces mechanical power which drives the alternator (generator) coupled to the turbine. Thermal Power Plants...

Our world’s advances in energy efficiency has been crucial to our technological, economic and social development. Creating energy has powered our advancements in modern machinery as well as stimulating our economy by creating jobs and improving our quality of life. But with these advancements came...

Hydroelectric power is a kind of renewable energy and have a very old history. The world first hydroelectric power plant has been exist and began operated at September 30, 1882 on the fox river in Appleton, Wisconsin. The electricity that generate in the world got...
