energy use and conservation

>Change lifestyles to conserve energy.(e.g. more use of mass transport systems or more use of bicycles as opposed to individual cars, use of solar devices solar air conditioning solar cooking etc.) Energy saved is energy produced..

Law of conservation of energy states that the energy can neither be created nor destroyed but can be transformed from one form to anothe..

It is a common experience that energy cannot be generated without consuming energy of some other kind. If a certain amount of one kind of energy is produced, an equal amount of some other kind of energy disappears so that the total energy of the Uni..

We can see many situations in which energy is transferred to or from objects and systems, similar to money being transferred between accounts. In each situation, we assume that the energy that was involved can be accounted for, that is, energy cannot appear or disappea..
