Solar could generate half of the world’s electricity by 2050 and become the cheapest source of energy, Gao Jifan, the chief executive officer of Trina Solar Co., said at the Boao Forum for Asia.

Global solar power capacity has the potential to grow to 14,000 gigawatts by the middle of the century from 800 gigawatts at the end of last year, Gao said in a panel discussion at the annual forum in Hainan. Chinese company Trina is the world’s third-biggest supplier of solar panels.
