Energy

What is Nuclear energy In the terms of theoretical physics energy is the ability to do work. You apply force and you get displacement. In a more practical world energy is heat, electricity, light etc. Per the theory of thermodynamics; energy is never destroyed it is changes form. I.e. heat/thermal energy converts to mechanical energy to move a car, nuclear energy to electric energy. Two major energy sources that the civilization requires now-a-days are, electricity and heat. Sun, the source of…

Alphabet Energy Matt Scullin is the PhD student in UC Berkeley and he has high interests in thermoelectric technology. In his academic career, he found that the traditional way of power generating wastes about 60% energy. While with the thermoelectric technology people can generate electricity from wasted heat and it can improve efficiency in 10% to 25%. By using his own technology, Matt started a company called alphabet energy and producing superior thermoelectric device. He narrowed his…

People have been finding, and using sources of energy since the beginning of mankind. Whether it is fire to cook, use streams and rivers to ride a canoe, to help grind corn, or coal to power trains across the world, humans have always relied on the valuable riches that the earth produces to survive However, most of the energy that is currently being used is nonrenewable, which means that it will not replenish as quickly as it is being consumed. An example of a nonrenewable resource currently…

Combustible energy- Combustible energy is a natural form of energy that has been formed and is continuing to be made over millions of years from organic matter. These are generally in the form of fossil fuels and come in 5 main forms: Coal, Petroleum, Natural Gas, LPG (liquified petroleum gas and crude oil. The method that is used to extract usable energy from combustible energy is by putting it through a fossil fuel power station. In these power plants, fuels are burnt to produce steam which…

1 20 October, 2016 Nuclear Energy vs. Renewable Energy Is Nuclear energy the solution for our future or is it the catalyst to the end of it? In our modern world we rely on two types of energy to fuel our technology: Nuclear energy, and Renewable energy. Nuclear energy produces energy from atoms, there are two ways to produce energy: nuclear fusion and nuclear fission. In nuclear fusion, two atoms are fused together forming a larger one, and in the process heat energy is created. In the other…

Geothermal energy is one of the oldest sources of energy. (Geo) a Latin root meaning earth and (thermo) a Greek root meaning heat, is where the word originates from. A simple way to phrase it would be that you are using renewable, heat energy from the earth. So what exactly does it do? According to an article by Alternative Energy Some forms of geothermal energy heats up groundwater. This heat eventually generates to hot spots surfacing near the surface of the crust. Examples of these hot…

concept of energy is very important to know because it is used in everyday life. Energy is used when getting out of bed just to dread going to school, heating up left overs, and even boiling some water. Energy cannot be destroyed or created, only passed from one object to another. A great example of energy is the transfer of heat. An ice cube sitting in the hand of a person can show energy at work. Heat from the hand causes the cube to melt and change forms into liquids. To understand energy a…

1: If 25.0 g of Al cool from 310oC to 37oC, how many joules of heat energy are lost by the Al? Heat Transfer q = m x Cs x ∆T q = C x ∆T • • • • • q = heat absorbed or released (J) Cs = specific heat (J g-1 K-1) C = heat capacity (J K-1) m = mass of substance (g) ∆T = change in temperature (K) = Tfinal -…

ourselves with new cleaner sources of energy and the explorations of the natural resources just may help. But is the exploration of natural resources may not be the greatest of solutions for our current environment. Take the world today we run on coal and fossil fuels that damage the earth 's ecosystems put the plant at risk of being uninhabitable. Therefore a need arises to examine alternatives and to look towards ‘greener’ conclusions. The world’s primary energy utilization is made up…

air, water, and land pollution. Sunlight received by the Earth is enough to meet the annual energy needs of all people worldwide according to National Renewable Energy Laboratory. The environmental advantages are the main drivers in the promotion of the use of solar panels and solar energy. Cell phones have become a necessity for plenty of people around the world. Cell phones allow people to keep in touch with their families, business clients, and access to the Internet, and so many more.…
