Energy can only be transformed from one from one form to other,such as, heat energy to motive power in cars, jet engine or kinetic energy of water flow to motive power to electricity in hydroelectric power plant.However machines are required to run to transform energy from one form to other.The wear and friction of these machine components while running cause loss of quadrillions of BTU and $500 billions industries in USA only.It is possible to minimize these losses by adopting green engineering practices to improve life cycle of the components.(Ref.R.Chattopadhyay:Green Tribology, Green Surface Engineering and Global Warming', ASM International,USA, 2014. Also 3 books by same author published earlier on wear, surface engineering and global warming.) ▼

'''Energy conservation''' is the effort made to reduce the [[energy consumption|consumption of energy]] by using less of an energy service. This can be achieved either by [[efficient energy use|using energy more efficiently]] (using less energy for a constant service) or by reducing the amount of service used (for example, by driving less). Energy conservation is a part of the concept of [[eco-sufficiency]]. Energy conservation reduces the need for energy services and can result in increased [[natural environment|environmental]] quality, [[national security]], [[personal security|personal financial security]] and higher savings.<ref name="zehner-2011">

Energy can be conserved by reducing wastage and losses, improving efficiency through technological upgrades and improved operation and maintenance. On a global level energy use can also be reduced by the stabilisation of [[population growth]].
