Principles Of Energy Conservation

Certain general principles govern the hypothesis and practice of Energy Conservation is as follows:

• The nature and scope of all energy employ must be challenged, involving the nature of application and the design and process of the devices.

• We should recognize that work is greater to heat, and wherever possible, helpful work must be completed at each stage of temperature or pressure decrease.

• Measurement is a pre-requisite not only for computing the energy conservation potential though also for charging its realization.  

• Waste heat recovery and utilization should go hand-in-hand. All waste heat recovered should be usable; an end-use should be specified before contemplating strategies for waste heat recovery. From commercial considerations, the value of the saving should exceed the cost of the WHR. Cost savings due to energy conservation should exceed all other costs acquired; the pay-back period should be commercially attractive.

• Waste of all kinds should be minimized. It is particularly significant for materials with high intrinsic energy content, like plastics, metals, glass, paper, refractory, and so on.

• Strategies for improving the design of systems to enhance durability and lifetime contribute also to energy conservation.

• Un-intentional recycling during manufacture outcomes in energy wastage, particularly in the situation of materials that can be simply re-processed.
