Potential Energy: Potential energy is the stored energy of position possessed by an object. Potential Energy Formula : Potential Energy: PE = m x g x h Mass: Acceleration of Gravity: Height: where‚ PE = Potential Energy‚ m = Mass of object‚ g = Acceleration of Gravity‚ h = Height of object‚ Examples: 1. A cat had climbed at the top of the tree. The Tree is 20 meters high and the cat weighs 6kg. How much potential energy does the cat have? m = 6 kg‚ h = 20

HISTORY OF SOLAR ENERGY Jake Tutorow Indiana Institute of Technology Fort Wayne‚ IN Abstract: The purpose of this paper is to explain the history of solar energy as well as the difficulties faced in acquiring government support and investments for infrastructure and technological gains. The history of solar energy is broken into five distinct categories: Earth energy‚ the ancient solar age‚ the modern solar age‚ solar in the 1950s‚ solar today‚ and agriculture. Earth energy focuses on the understanding

BERNOULLI AND ENERGY E Q U AT I O N S his chapter deals with two equations commonly used in fluid mechanics: the Bernoulli equation and the energy equation. The Bernoulli equation is concerned with the conservation of kinetic‚ potential‚ and flow energies of a fluid stream‚ and their conversion to each other in regions of flow where net viscous forces are negligible‚ and where other restrictive conditions apply. The energy equation is a statement of the conservation of energy principle and is

Proposal Energy Audit: An energy audit is an inspection‚ survey and analysis of energy‚ flows for energy conservation in a building‚ process or system to reduce the amount of energy input into the system without negatively affecting the output(s). Energy audit identifies opportunities for financial savings by elimination of wasteful use of electricity‚ coal and fuel oil‚ without affecting the process or quality of product. Need for Energy Audit: It has been established that Energy savings

What is "energy"? Where does it come from? And how do we pay for it? When you learn the answers to these questions‚ you can also learn how to live more efficiently in your home. In this article‚ we ’ll discuss how to be smart about how you use energy‚ how to know when to turn electrical power on and off‚ and how to use natural gas‚ propane‚ and fuel oil in the most effective way. Basic Concepts of Energy Efficiency You can make a lot of progress toward improving the energy efficiency in your

AIU Energy‚ Metabolism‚ and Cells- Unit 2-IP April 1‚ 2012 Professor Kelli Roberts Energy‚ Metabolism‚ and Cells Photosynthesis is the process that pretty much every organism on earth needs‚ because of the nutrients produced which is needed in order to live. Plants capture the energy from the sun and converts it into food that is needed by all plants and animals (including us as humans). In this process the chemical reaction which is known as photosynthesis‚ it takes the sun’s energy and

2013 University of Phoenix The lives of the organisms in the desert require a substantial amount of survival skills. The temperature in a desert biome is always very high and it does not rain very often so it is also extremely dry. Any organisms that live in the desert must be able to adapt to these conditions in order to live. For example‚ one organism that can be found in the desert is cacti. Cacti roots are closer to the surface than other plants so it is able to drink the rain water. They

Energy sustainability in the UAE | Abstract This research will discuss about the current energy resources consumption locally in the UAE and globally in the whole world. Also‚ it would discuss about the possible renewable energy plant implementation and what new researches and achievements has been done in the UAE. Most of the researches done in the area of the energy sustainability are based in Masdar city and so more detailed information are provided. Table of contents Abstract 1

the demand of energy in Pakistan as a result of industrial development and population growth‚ as compared to increase in energy production. The number of energy consumers has increased to 12.5 million: household 46 per cent‚ industry 28 per cent‚ agriculture 12 per cent‚ bulk supply nine per cent and commercial five per cent. For faster economic growth‚ Pakistan need more generation. Supply of energy is‚ therefore‚ far less than actual demand‚ resultantly crisis has emerged. An energy crisis can be
