Energy Conservation 1 Energy conservation is the reduction or elimination of unnecessary energy use and waste. This practice may result in increase human comfort‚ personal security‚ national security‚ environmental value‚ and financial capital. There are many activities that people can do to conserve energy and help not only themselves‚ but also the environment and everyone around them. Conserving energy is important because most of our current energy sources are not renewable. When using

physics‚ energy is an indirectly observed quantity which comes in many forms‚ such as kinetic energy‚ potential energy‚ radiant energy‚ and many others; which are listed in this summary article. This is a major topic in science and technology and this article gives an overview of its major aspects‚ and provides links to the many specific articles about energy in its different forms and contexts. The question "what is energy?" is difficult to answer in a simple‚ intuitive way‚ although energy can be

LESS ENERGY Year 9 In the UK our homes contribute significantly to the carbon dioxide in the atmosphere. Becoming more energy efficient will help to reduce the amount of carbon emissions we create and the amount of energy we need to power our homes. If every home reduced their energy consumption by 20% the UK would meet the 2020 targets set by the European Union. However due to out-dated methods of construction in older properties it is not always a easy task to become more energy efficient

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

PRESENTATION FOR 8-Cs PROJECT Gas which is used for burning is produced from the fossil fuels‚ which at the moment are decreasing at a much faster rate than they are being produced. Cow Dung is a place below earth surface where all waste of animals and rubbish from city is stored. Together the waste of animals and rubbish produces a gas called bio-gas which can be used for burning. In this way‚ rubbish which is burnt & makes pollution can be made into a useful gas and our fossil fuels can be saved

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
