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 Israeli homes use solar energy for hot water, the highest per capita in the world. 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 Desert. Israel had a modern electric car infrastructure involving a countrywide network of recharging stations to facilitate the charging and exchange of car batteries. It was thought that this would have lowered Israel's oil dependency and lowered the fuel costs of hundreds of Israel's motorists that use cars powered only by electric batteries. The Israeli model was being studied by several countries and being implemented in Denmark and Australia. However, Israel's trailblazing electric car company Better Place shut down in 2013.
