Identity Crisis- A quest to find one’s true place. There are some deep tragic incidents which have left a lifelong impact. Some of the effects these impacts leave behind are physical while others are mental and cannot be healed easily. Such events go down the history of the most unfortunate happenings ever. The most disturbing mental strains are the ones which arises out of social insecurity. Social insecurity is a state in which a person starts feeling isolated from the rest of the world

ESSAY ON ALTERNATIVE SOURCES OF ENERGY The law of conservation says that energy is neither created nor destroyed. When we use energy‚ it doesn’t disappear. We change it from one form of energy into another. A car engine burns gasoline‚ converting the chemical energy in gasoline into mechanical energy. Solar cells change radiant energy into electrical energy. Energy changes form‚ but the total amount of energy in the universe stays the same. Scientists at the Department of Energy think they have

The solar energy use in Africa These days‚ solar energy has been the most talkative alternative energy source in the world. Unlike the gas‚ oil‚ and coal‚ solar enrgy is one of the clean and renewable resource‚ which can not only generate power but also protect the environment. Africa‚ has second largest population‚ estimated 1.6 billion‚ however‚ around one third of it’s people still live in the condition with no eletricity. (Renewable energy in Africa

Studyonlinenow Renewable Energy Is Only Part of the Best Way to Prevent Climate Change In our present life we are going through two of the main hazardous changes on the Earth‚ global warming and greenhouse affects. We want mankind to survive for a very long time‚ but if we keep using non-renewable energies the way we do‚ do you think we will be able to survive for a long time? I strongly believe that renewable energy is only part of the best way to prevent climate change. In this essay I intend to present

from the Economist‚ energy problems are discussed‚ particularly the problems connected to intermittent renewable energy sources and the need to store energy so that it can be used when needed. Do you agree that better ways of storing energy would make generating electricity cleaner and more efficient? Write an essay of between 300 and 370 words on this topic‚ briefly summarising the different solutions to energy storage presented in the text‚ presenting your view on whether energy storage can be a

ENERGY MANAGEMENT PRINCIPLES INTRODUCTION In the modern days energy has the significant role in our life. With development where we got comfortable life and much modern facilities where we got some problem with excessive use of energy resources as declining of energy sources‚ climate change. So it is an big challenge for present and future generations as the cost of energy increase and its supply decrease‚ older buildings needs to modified and new buildings designed to use less energy. The optimization
