Chinese Premier Wen Jiabao on Tuesday urged developers of Olympic stadiums and gymnasiums to promote energy efficiency and environmental protection in their construction.

Wen was inspecting the national stadium, the swimming stadium and the hockey stadium, which are under construction.

"China will not show extravagance in organizing the Olympic Games. We should save every drop of water and every kilowatt-hour of electricity in the construction of the Olympic facilities," said Wen.

Saving energy and environmental protection should be implemented in every project, Wen said.

He also urged developers to ensure the quality and safety of Olympic projects, to strengthen management and be thrifty in construction, and take the future use of the facilities after the Games into consideration.
