Question

content for speech on energy conservation

Answer 1

More than 8% of the electricity you buy is probably wasted due to the design of your equipment and the way it has been installed. This is in addition to the energy wasted by running equipment for longer than necessary. Electricity is the most expensive form of energy available – about 8 times the cost of coal and six times the cost of gas – this expensive fuel must be used wisely.

No organization, whatever its size, can afford to overlook the improvement in profit and competitive position which can be achieved from the careful and thorough application of energy saving initiatives. When investment opportunities are being assessed and compared by management, energy saving initiatives are too often given a much lower priority than production and development projects.

This is despite the fact that energy saving initiatives can reduce revenue expenditure over the whole organization with very low capital investment requirements and can continue to do so over a very long period. Among the reasons given for this has been shortage of capital to invest and short-term company policies and it has been difficult for energy managers to gain the necessary support for energy saving projects.

Identification of energy saving opportunities must be carried out in a systematic manner so that it can be shown that the initiatives proposed are those which will yield the greatest benefits. Major opportunities will arise during the planning of new buildings and plant where the incremental cost of high efficiency equipment will be easy to determine, the lifetime will be longest and there will be no or little, difference in installation costs.

There will be many instances where the installation of more modern equipment will be so beneficial that the replacement of existing equipment before its normal end-of-life will be justified by savings on running costs. Experience gained by monitoring the performance of new plant and comparing with it older plant will provide useful data.

Careful and systematic monitoring will be required to identify energy saving opportunities. It is essential that the energy demands and costs of every aspect of the business are well understood, so that areas of greatest waste can be identified and tackled and that solutions for one situation can be applied to similar areas.

Full records should be maintained so that cost savings can be demonstrated and so that previously identified opportunities can be re-visited as costs and engineering solutions change. An organised approach will help to show management that the best investments are being selected for further work.

Answer 2

Energy conservation refers to the methods of reduction in energy consumption by way of elimination of wastage and promotion of efficiency. We know that due to the vast gap between demand and supply, lot of efforts is being done to bridge the gap in terms of generation of more electricity which requires lot of capital investment and apart from it creates lot of environmental concerns
Energy conservation is the key element of energy management. We can reduce the energy consumption by adopting various ways of energy conservation which includes efficient use of technologies and avoiding energy wastages.

The various principles involved in energy conservations are:

(i) Optimal control.

ii) Optimize capacity.

(iii) Optimize load.

(iv) Use efficient processes.

(v) Reduce losses.

(vi) Energy containment
