Implementation of an effective energy management program, as far as India is concerned, would lead to energy sufficiency and environmental safety. Thus a coordinated world-wide action plan is, therefore, necessary to ensure that energy supply to humanity at large is assured for a long time and at low economic cost.The following factors need to be considered and actions to be taken accordingly: (i) Energy consumption curtailment; (ii) To initiate concerted efforts to develop alternative sources of energy including unconventional sources like solar, tidal, geothermal energy etc.; (iii) Recycling of nuclear wastes; (iv) Development and application of anti-pollution technologies.Examples: Diesel generators, solar PV installations, kiosk type mini hydro-plants, fuel cells and wind generators etc. Power: Any physical unit of energy when divided by a unit of time automatically becomes a unit of power.

It was then the first time that nations importing petroleum products felt the shock when the petro-nations demanded higher price.

The energy crisis of 1973 forced the world to look for an alternative arrangement to ensure energy sufficiency.

Introduction of energy efficient technologies and effective energy management has made this possible.

Efficiency of energy utilization needs to be a continuous activity as there is lots unproductive energy utilization generally observed in Indian industrial sector.

Energy has always been a vital resource in the development of any nation.

The prosperity of a nation is measured in terms of per capita energy consumption besides GDP, GNP, etc.In-efficient use of energy has stretched the global environment to its limits as can be seed from the unprecedented and unpleasant responses of the nature in the past few years. First law of thermodynamics relates to conservation of energy and throws light on concept of internal energy. Second law of thermodynamics indicates the limit of converting heat into work and introduces the principle of increase of entropy. (ii) Can be easily and economically transported from one place to another over long distances. Electrical energy is obtained, conventionally, by conversion from fossil fuels (coal, oil, natural gas), the nuclear and hydro sources.Green -house effect, global warming, acid rain, smog, deforestation, shift in climatic conditions, etc. The carbon dioxide level in the atmosphere increased from 280 ppm in 1850 to 360 ppm at present. Heat energy released by burning fossil fuels or by fusion of nuclear material is converted to electricity by first converting heat energy to the mechanical form through a thermocycle and then converting mechanical energy through generators to the electrical form.“Sunderbans” in West Bengal was not accessible to grid power but was electrified during 1997 by solar power 410 k W by SPV modules, and biomass-based power plant of (5 x 100) k W.Dispersed Generation: It refers to the use of generating units of less than 25 k W output to serve individual homes, business and defence installation in remote areas.This promised an immediate, long term and multi-faced solution to the problems immerging from increased energy demands against short supplies.Energy management has since become the key word for any profitable industrial unit.Besides now the ‘energy’ accounts for a sizable share in the cost of production in most of the industries.As a result of this, positive trends have been noticed over the past decade in the energy use pattern the world over.While the world has seen hectic industrial activity in the past century it has also come face to face with serious problems arising out of haphazard utilization of the energy resources.The concept was ‘More the resources (energy), more the development’.
