China to host world’s 
first green energy expo next month

2010. 2 April

by Karel Smrcka
( On May 1, Expo 2010, in Shanghai, will open its doors to the world. About 70-million visitors are expected in the Chinese metropolis. 
It is supposed to be the first green world exhibition in expo history.

Siemens supplied most of the necessary infrastructure to ensure that the stream of visitors are accommodated in an environment-friendly manner.

The company was awarded contracts in connection with the expo with a total value of more than €1-billion. About 90% of this amount is related to environment-friendly products and solutions.

As a global expo partner, Siemens has supplied technology used in more than 40 projects on the expo grounds. 
In addition, Siemens supplied infrastructure that will make this event memorable for all its visitors, including technology for rapid mass transit, clean air, cleaner water and 
ultramodern healthcare.

In total, about 60 pavilions were built on the exhibition grounds, and five will remain open to visitors after the exhibition. 
These are the China Pavilion, as the landmark of the expo; the Expo boulevard, which is about 1 000 m long; the Theme Pavilion; the Expo Centre; and the Performance Centre, which boasts 18 000 seats.

Better City, Better Life
Solutions for sustainable urban development will be exhibited in the pavilions and even the expo grounds themselves are a perfect 
example of green urban infrastructure.

More than 50 000 energy-saving light-emitting diodes (LEDs) produced by Siemens’ lighting subsidiary, Osram, illuminate the pavilions and boulevards. LEDs consume 80% less electricity than conventional incandescent bulbs.

The China Pavilion, with a total surface area of 160 000 m2, is one of the largest Siemens projects at the expo. 
Built entirely using energy-saving technology, it is destined to be remembered as the expo’s green landmark.

Another prime example of the energy 
efficiency provided by Siemens technology is Hamburg House, a so-called ‘passive house’ that consumes less energy than nearly any other building in the world. 
In fact, it will generate nearly all the 
energy it needs from the warmth of appliances 
used in the house and the people who will visit the house during the expo. 
Hardly any greenhouse gases are generated.

Coal-Fired Plant

In addition to solu-
tions for reduced energy consumption, Siemens also supplied infrastructure in advance of the expo that will ensure sufficient power supplies to the city of Shanghai during and after the event. 
This summer, when energy consumption peaks in Shanghai, as it does every year, the anticipated millions of visitors to the expo will pose a severe test for the city’s energy supply.

The demand will be met by the world’s most efficient coal-fired power plant, in Waigaoquao. 
Built by Siemens, this plant alone meets 30% of Shanghai’s energy demand, but, compared with conventional coal-fired power plants in China, it uses more than one-million tons less coal. 
The higher efficiency reduces the power plant’s carbon dioxide emissions by almost three-million tons a year.

Further, just outside Shanghai, Siemens will open its first wind energy production site this year. 
The facility will meet the demand for wind blades for the Chinese market and beyond.
Through this facility, China can accommodate a bigger portion of its growing demand for power with electricity from renewable sources.
