Why the Saudis Are Going Solar

Near Riyadh, the government is preparing to build a commercial-scale solar-panel factory. On the Persian Gulf coast, another factory is about to begin producing large quantities of polysilicon, a material used to make solar cells. And next year, the two state-owned companies that control the energy sector—Saudi Aramco, the world’s biggest oil company, and the Saudi Electricity Company, the kingdom’s main power producer—plan to jointly break ground on about 10 solar projects around the country.
