A solar project funded and operated by both Jews and Muslims is shining some light on Auja, a small Palestinian town located in one of the most controversial territories on Earth. The $100,000 project is harnessing solar energy to power the drawing of water from deep underground to irrigate a grove of palms growing the prized Medjool dates. It is the first large project to be funded by both Jews and Muslims in the United States including former New York City Mayor Michael R. Bloomberg and to be operated by Israeli Jews and Palestinian Muslims on the ground. The solar array is providing an economic boost to 45 farming families in this town of 5,000 Palestinians on the eastern flank of the West Bank who struggle with scarce water and unreliable and expensive electricity. Ben Jablonski ... is leading the project through a nonprofit he founded called Build Israel Palestine. Mr. Jablonski, who is Jewish, started the organization in 2014 with Tarek Elgawhary, an Egyptian Muslim religious scholar in Washington, D.C. who also runs Coexist, an educational nonprofit. Jablonski gave up his board seat with the Jewish National Fund, a nonprofit infrastructure developer that has limited but controversial involvement in West Bank settlements, in order to meet the demands from the Auja community, which insisted that donors and engineers involved in the project have no connections to Israeli settlements. Build Israel Palestines work focuses on providing Palestinians access to water, and doing so by bringing Muslims and Jews together.
