Construction is in the works for what China is calling “The Biggest Solar Energy Production Base in the Whole World,” or more simply, Solar Valley. The base will be a clean energy technology hub that China hopes will rival Silicon Valley in California. The ambitious plans for the park were launched by Himin Solar Energy, whose headquarters is located at the Sun-Moon Mansion, which is currently the largest solar powered office building in the world. The planned development outside of Dezhou, China is expected to cost $740 million and accommodate 100 tenants.
