Information Governance. Documented processes that define how information is controlled, accessed, and used are needed more than ever in a cloud environment. An executive-sponsored framework is recommended to take information governance into the cloud. Project Management. Finally, change control, project management, and program management are equally important. With today’s standard IT silos, storage initiatives are managed, tracked, and reported on by the storage director; server initiatives are managed, tracked, and reported on by the systems director; and so on. As the lines blur, who is responsible for cloud initiatives? Who owns that budget and is responsible for. | CHAPTER 16 ENERGY AUDIT CONSERVATION OF ENERGY INTRODUCTION Energy is very scarce commodity particularly in developing and underdeveloped countries. Cost of energy is spirally increasing day-by-day. Generally pumping installations consume huge amount of energy wherein proportion of energy cost can be as high as 40 to 70 of overall cost of operation and maintenance of water works. Need for conservation of energy therefore can not be over emphasized. All possible steps need to be identified and adopted to conserve energy and reduce energy cost so that water tariff can be kept as low as possible and gap between high cost of production of water and price affordable by consumers can be reduced. Conservation of energy is also important and necessary in national interest as the nation is energy deficit due to which problems of low voltage load shedding and premature failures of equipments are encountered. Some adverse scenarios in energy aspects as follows are quite common in pumping installations Energy consumption is higher than optimum value due to reduction in efficiency of pumps. Operating point of the pump is away from best efficiency point . . Energy is wasted due to increase in head loss in pumping system . clogging of strainer encrustation in column pipes encrustation in pumping main. Selection of uneconomical diameter of sluice valve butterfly valve reflux valve column pipe drop pipe etc. in pumping installations. Energy wastage due to operation of electrical equipments at low voltage and or low power factor. Such inefficient operation and wastage of energy need to be avoided to cut down energy cost. It is therefore necessary to identify all such shortcomings and causes which can be achieved by conducting methodical energy audit. Strategy as follows therefore need to be adopted in management of energy. i Conduct thorough and in-depth energy audit covering analysis and evaluation of all equipment operations and system components which have bearings .
