??? RENEWABLE and clean energies will be used in the construction of Sina-German Ecological Park. Renewable energy sources to be used at the park include wind and solar power, geothermal heat and biomass energy. Wind and solar power will play the largest roles. All buildings in the park will connect with an intellectual power network and include balconies solely dedicated to the installations of solar power equipment, plans state. Meanwhile, the park also will build an energy network connecting with the Internet and associated resources to make better use of energy. Natural materials will be used in the construction to save energy and resources. (Wang Yuanyuan, Han Guangliang, Zang Fugui) |
