Israel hopes to generate 10% of its energy from renewable sources by 2020, and is developing several projects to ensure this. 

The Israel-based Megalim Solar Power company is building a 240 meter (787-foot) tall solar tower in the south. When completed, it will generate up to 121 megawatts of power, providing about 1% of Israel’s electricity consumption.

Construction completion is expected in late 2017.

Israel aims to generate 10% of its energy demands from renewable sources by 2020. With its ample sunshine, Israel has excellent potential to tap into solar power as a renewable energy source.

While most solar energy is produced by photovoltaic panels which can be installed anywhere, solar towers are large-scale projects that use concentrated solar power generated by thousands of mirrors that project the sun’s rays.

The Ashalim solar tower in the Negev is surrounded by 50,000 computer-controlled mirrors which are larger than those used in previous projects and controlled over a dedicated Wifi network rather than cables, which is expected to cut production costs. The mirrors track the sun and concentrate sunlight onto a boiler on top of the tower. Utilizing the high temperatures and high pressure, the steam turbine will be able to generate sufficient electricity to supply 120,000 homes with clean energy each year, at an annual savings of 110,000 tons of CO2 emissions.

The project also takes into account another aspect of environmental protection: protecting wild life. In order to prevent heat from the mirrors harming the millions of birds that migrate through Israel annually, the tower will ward off the birds by spraying vaporized grape skin extract and emitting sounds of natural predators.

Over the past years, Israel has become a leading force in clean technologies and a global exporter of renewable power sources.

Israel’s cleantech projects are globally renowned, with innovative ideas such as powering entire buildings through the use of solar panels, converting wind into electricity, new technologies for clean water and many other inventions that are making the world cleaner and more energy-efficient.
