Isreal’s fledgling solar industry, which is far behind even countries with cloudier and colder climates, is trying to make a statement about its renewal energy ambitions with a large-scale project that will boast the world’s tallest solar tower. The Ashalim project, deep in the Negev desert, is made up of three plots, with a fourth planned for the future, each with a different solar technology. The centerpiece will be a solar tower standing 250 meters (820 feet) tall and encircled by 50,000 mirrors. Together, the fields will be Israel’s largest renewable energy project when completed by 2018, generating 310 megawatts, enough to power about 130,000 households, or roughly 5 percent of Israel’s population, according to Israel’s Electricity Authority. Israel has set a goal of generating 10 percent of its energy from renewable sources by 2020, up from the current 2.5 percent.
