Safest Form of Energy for the Future Natural resources are materials or substances such as minerals‚ forests‚ water‚ and fertile land that occur in nature and can be used for economic gain. Human life is dependent on natural resources‚ so there is a concern that we may eventually run out of them. There are many alternative energy sources that could be used as a substitute to natural resources in the future. There are many different types of alternative sources of energy to choose from‚ but in my

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

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

the three energy systems that are responsible for the production of ATP. Adenosine triphosphate (ATP) is the immediately usable form of chemical energy use for muscular activity. It is stored in most cells‚ especially muscle cells. Other forms of chemical energy‚ such as that available from foods we eat must be transforming into ATP before they can be utilized by muscle cells . Human body cells generated ATP by three methods which are: I. ATP-PC system II. Glycolytic system III. Oxidative

The Energy of the Future The United States of America is in desperate need of an alternate energy source. One such alternate source is nuclear power. Nuclear power is a form of energy produced by an atomic reaction‚ which is capable of producing an alternative source of electrical power‚ replacing the energy currently supplied by coal‚ gas‚ or oil. This will help the United States move away from burning fossil fuels and potentially reduce overall pollution. Nuclear power has the potential to be
