Saudi Arabia's sovereign wealth fund and the SoftBank Group Corp. of Japan announced plans last night for what would become the world's largest solar power project in the kingdom, developing 200 gigawatts of new solar power capacity by 2030, the Wall Street Journal reports.

Why it matters: If the plan actually comes to pass, well, that's a lot of solar. By way of comparison, the U.S. added a total of 10.6 GW of new solar PV capacity last year, according to a recent industry report. Plus — it also underscores Saudi Arabia's efforts to diversify its oil-dependent economy.
