Energy is an important part of our life‚ and no human being in the 21st century can live without it‚ energy now a day means electricity and electricity is running our world‚ with no energy there will be no electricity and then no hospitals‚ no technology and we will go back to stone ages. Energy sources on planet earth can be classified into two types‚ “renewable” and “nonrenewable” energy sources‚ they both differ in many aspects‚ both of them have advantages and disadvantages‚ and both of them

TIDAL ENERGY [pic] *75% of the planet’s surface consits of water. Our water supply transformed a barren planet into a lush green garden of life with a multitude of biodiversity. Water has easily fufilled our every need in many ways. As we near the twentyfirst century‚ a time when public attention is focused on the environment and society is increasing at an ever accelerating rate‚ the energy crisis continues to burden us. Questions of what to do about increasing energy demands and future requirements

atmosphere–ocean system and motivates the deeper examination to follow. The character of coupled atmosphere–ocean interactions is briefly introduced. Simple energy balance models are derived and used to illustrate the fundamental mechanisms behind variations of temperature with altitude‚ latitude‚ and season. The global annual mean energy balance is then presented and briefly discussed. Finally‚ the origins‚ thermodynamic structure‚ and composition of the atmosphere and ocean are summarized.

young people‚ athletes and students‚ drink energy drinks like: Red Bull‚ Rock Star and Monster almost every day to survive in their busy life. However‚ these people do not know the dangerous side effects and the harm which these energy drinks can make in their body. A research was conducted by Mayo Clinic hospital says that Energy drinks related emergency visit double in the hospital in the last 4 years. The same study also says that drinking energy drinks might lead to a very dangerous diseases

Definition of Wind Energy “Wind Energy - Energy received from the movement of the wind across the earth. This energy is a result of the heating of our oceans‚ earth‚ and atmosphere by the sun. Turbines convert the kinetic energy of wind into mechanical or electrical energy that can be used for power.” The German physicist Albert Betz calculated in 1919 the possible maximum amount of energy that can be extracted out of wind energy. He came to the result of 59.3% that can be extracted and named this

Keeping in view the commercial and industrial consumption of oil and gas everyone is conscious to have some alternate resource for energy production. Wind is also one of the resources for the power generation. A wind turbine is a device that converts kinetic energy from the wind‚ also called wind energy‚ into mechanical energy; a process

Atomic energy By: Hiram A. Murray III Background info The origin of the phrase atomic energy check in from the years of 1905-10. It is defined as energy released by reactions within atomic nuclei‚ as in nuclear fission or fusion. Now a days it is referred to Nuclear energy. Nuclear power uses fission (splitting atom nuclei) to produce energy. Atom nuclei is also none as the nucleus (center of the atom). Around 6% of the world’s energy and 14% of the world’s electricity is produced by nuclear

Energy transfers which take place in living organisms The nucleotide ATP (adenosine triphosphate) maintains both catabolic and anabolic reactions. Catabolic reactions e.g. respiration are where larger molecules are broken down into smaller ones with energy being released‚ and anabolic reactions e.g. photosynthesis are where smaller molecules are built up into larger ones which require energy. Catabolism provides the energy for organisms to synthesise larger molecules in its anabolic reactions.

Cooper‚ senior fellow for economic analysis at Vermont Law School’s Institute for Energy and Environment. Estimates of construction costs — about $3 billion per reactor in 2002 — have been regularly revised upward to an average of about $10 billion per reactor‚ and the estimates are likely to keep rising‚ said Mr. Cooper‚ an analyst specializing in tracking nuclear power costs. Identifying the real costs of competing energy technologies is complicated by the wide range of subsidies and tax breaks involved

Geothermal energy has been used for thousands of years in some countries for cooking and heating. It is simply power derived from the Earth’s internal heat.This thermal energy is contained in the rock and fluids beneath Earth’s crust. It can be found from shallow ground to several miles below the surface‚ and even farther down to the extremely hot molten rock called magma. These underground reservoirs of steam and hot water can be tapped to generate electricity or to heat and cool buildings directly
