(ECNS) -- Located in Shanghai's Pudong New Area, the roof of the Metro Longyang Road depot is covered by solar panels.
Seen from above, the big "M" stands for Metro while the green lawn represents environmental protection.
This subway base, also a solar power plant, generates an average 3.4 million kilowatt-hours of electricity per year.
The generated power can enable an eight-cabin metro train to run 200,000 kilometers, saving about 1,200 tons of standard coal and reducing carbon dioxide emissions by 3,390 tons.
