Energy efficiency improvement procedures and audit results of electrical, thermal and solar applications in Palestine

Energy conservation in utilities has played a vital role in improving energy efficiency in the industrial, commercial and residential sectors. The electrical energy consumption in Palestine has increased sharply in the past few years and achieved by the end of 2001 to 10% per year. It is expected that this percentage will increase to about 12% if the current political situation will end hopefully with peace. Modern energy efficient technologies are needed for the national energy policy. Such technologies are investigated in this paper. Implementing of a national 3 years project aiming at energy efficiency improvement in residential and industrial sectors as well as in public utilities, which include wide range of diversified audits and power measurements, had led to creating this paper. Measurement and audit results had shown that the total conservation potential in these sectors is around 15% of the total energy consumption. The associated costs of the investment in this field are relatively low and correspond to a pay back period varying in the range from 6 to 36 months. Consequently, the energy conservation policy will be seriously improved in the forthcoming years. It is estimated that 10% of the new energy purchasing capacity will be reduced accordingly.
