  Israel's development of cutting-edge technologies in software, communications and the life sciences have evoked comparisons with Silicon Valley. Israel is first in the world in expenditure on research and development as a percentage of GDP. It is ranked 15th in the Global Innovation Index in 2024, and 5th in the 2019 Bloomberg Innovation Index. Israel has 140 scientists, technicians, and engineers per 10,000 employees, the highest number in the world and has produced six Nobel Prize-winning scientists, mostly in chemistry, since 2004 and has been frequently ranked as one of the countries with the highest ratios of scientific papers per capita. Israeli universities are ranked among the top 50 world universities in computer science (Technion and Tel Aviv University), mathematics (Hebrew University of Jerusalem) and chemistry (Weizmann Institute of Science).
  
  In 2012, Israel was ranked ninth in the world by the Futron's Space Competitiveness Index. The Israel Space Agency coordinates all space research programmes with scientific and commercial goals, and have designed and built at least 13 commercial, research and spy satellites. Some satellites are ranked among the world's most advanced space systems. Shavit is a space launch vehicle produced by Israel to launch small satellites into low Earth orbit. It was first launched in 1988, making Israel the eighth nation to have a space launch capability. In 2003, Ilan Ramon became Israel's first astronaut, serving on the fatal mission of Space Shuttle Columbia.
  
  The ongoing water shortage has spurred innovation in water conservation techniques, and a substantial agricultural modernisation, drip irrigation, was invented in Israel. Israel is also at the technological forefront of desalination and water recycling. The Sorek desalination plant is the largest seawater reverse osmosis desalination facility in the world. By 2014, desalination programmes provided roughly 35% of the drinking water, and it is expected to supply 70% by 2050. As of 2015, over 50 percent of the water for households, agriculture and industry is artificially produced. In 2011, Israel's water technology industry was worth around $2 billion per year with annual exports of products and services in the tens of millions of dollars. As a result of innovations in reverse osmosis technology, Israel is set to become a net exporter of water.
  
  Israel has embraced solar energy; its engineers are on the cutting edge of solar energy technology, and its solar companies work on projects around the world. Over 90% of homes use solar energy for hot water, the highest per capita. According to government figures, the country saves 8% of its electricity consumption per year because of its solar energy use in heating. The high annual incident solar irradiance at its geographic latitude creates ideal conditions for what is an internationally renowned solar research and development industry in the Negev. Israel had a modern electric car infrastructure involving a countrywide network of charging stations; however, its electric car company Better Place shut down in 2013.
