In most of the developing countries, the energy sector consumes the major importance with the ever increasing energy needs and the widening demand and supply of this. In the current scenario, the peak demand shortage is 14% and the energy deficit is 8.4%. So, more efforts are being given on the use of the energy efficient lighting and energy efficiency is achieved, when the usage of the energy products is reduced without affecting the output. And, also it has been observed that the energy efficient lighting touches the normal lives of many of the people.
So, today the energy efficiency assumes the greater importance as it is most cost effective and reliable means of meeting the global climate change. And more than this, the use of energy efficient lighting is very important and has become an important component of the society.
Energy efficient lighting also means using the less energy in order to perform the same function, for example: it can be done by replacing the traditional light bulbs with the compact fluorescent bulbs, as it has been observed that, one uses only 25% of the energy for the household purposes. And, it accounts for nearly 15 % of the total energy consumed in the developing countries. Thus, the developing countries are taking more initiatives in order to improve the energy efficiency.
However, many problems occur during the successful drive towards the energy efficient lighting. Some of these include: giving stress towards minimization of first cost by end users. It even faces the problem for the availability of the capital. Then, lack of information and also shortage of the skilled labourers also contribute to the problems faced by the government.
There has also been continuous growth and development in the energy saving lightings in the recent years, in order to produce the best lighting products and control the energy consumption. And, also in industrial plants, the use of the efficient lighting does not hold importance. Thus, in order to implement the energy conservation measure, the total expenditure on investment is incurred for implementation. For example, nearly 40 % of the energy can be saved in a normal office building with the efficient use of the ballasts, lamps, and reflectors.
