Energy can neither be created nor be Destroyed then why we need to conserve it. explain??

Energy comes in different forms and one form can be converted into another form. For example-it we light a candle, the process is highly exothermic so that the chemical energy in the candle changes into light energy on burning. The total energy during a physical and chemical process remains the same but we cannot again put together the heat and light generated alongwith the products of the reaction to get back the chemical energy in the form of wax. Hence, energy, in the usable form, is dissipated to the suroundings in less usable forms. So the sources of enrgywe use to do work is consumed and cannot be used again.
