An Israeli report revealed the Israeli economy loses approximately U.S. $2.7 million daily because of the suspension of Egypt's gas flow to Israel. Israel now consumes a large amount of diesel fuel to generate electricity since January to August, and the increase of diesel consumption reached a rate of 103 percent. Israeli economy newspaper Calcalist reported Israel received diesel fuel for U.S. $160 million during July and August of 2011. Calcalist revealed Egypt provided Israel with 40 percent of its need of gas until February 2011, but after the explosion of the gas pipelines that transfer gas to Israel, Israel started to use diesel fuel, which is expensive and an environmental polluter. The head of Ganoub El-Wadi petroleum holding Co., Sherif Ismail, said the prices of gas export to Israel and Jordan will remain secret, since it affects negotiations held between both sides.
