Earthhour at the Eilot Hilton Queen of Sheba Resort in Israel with the Wind Tulip wind turbine

20 cities throughout Israel dimmed their lights for 60 minutes on Thursday night to mark 2011 international Earth Hour www.earthhour.org.

Israel marked the hour on Thursday, at 8:30 p.m. local time, instead of Saturday like the rest of the World, to avoid problems with the Shabat. The 20 cities began their hour-long lights-out periods at consecutive 10-minute intervals beginning at 8 p.m., with Tel Aviv-Jaffa, Yeroham and Modi'in- Maccabim-Reut, followed by Jerusalem and Dimona at 8:10 p.m.; Petah Tikva, Ness Ziona and Ra'anana at 8:20; Netanya, Rehovot, Arad, Eilat and Yavneh at 8:30; Ashdod, Givatayim, Herzliya and Bat Yam at 8:40; and Holon, Haifa and Yokne'am at 8:50 p.m.

The Israel Electric Corp. said that it would show online afterwards whether the cities had successfully reduced their typical energy usage for that hour, according to Ilan Arnon, IEC North District spokesman.


In Eilat, during the lights-out period, Leviathan Energy's brand new Wind Tulip turbine was set into operation at the entrance to the Hilton Hotel Queen or Sheba Resort.

"One of the nice things about it is that it's meant to be beautiful as well as effective," said Dr. Daniel Farb, CEO of Leviathan Energy Renewables, Ltd., prior to the launch.

Shaped like its floral namesake, the Tulip is smaller and more solid than the typical wind turbine and was designed aerodynamically to be very low in noise and vibration.
