Saudi Arabia is the world's largest oil exporter, but falling oil prices have made it more difficult for the country to pay its oil workers.
Now the Saudi Arabian government has come up with a project that could give its economy a boost: a $500 billion mega-city that will connect to Jordan and Egypt and be powered completely by renewable energy.
In October 2017, Saudi Crown Prince Mohammed bin Salman announced the project, called NEOM, at the Future Investment Initiative conference in Riyadh. It will be financed by the Saudi government and private investors, according to Reuters.
