A new Chinese solar project, costing just $1.65 billion, has an annual output of 5.7 billion kilowatt-hours (kWh) - half that of an average nuclear power plant.

This is the Mengxi Blue Ocean Photovoltaic Power Station, now China’s largest single-capacity solar power plant. Worth noting is that it's built in the Gobi Desert, an area twice the size of Ukraine. So there's room for plenty more.

Without grid storage, this is priced at about 10% of the cost of new nuclear projects.
