Taiwan will open an exhibition on Thursday to showcase new eco-friendly technologies and products and educate people on how to lead a low carbon emission lifestyle. More than 200 companies, government agencies and institutions will take part in the ECO Taiwan Expo, which will be held for the first time Oct. 21-23. The expo will feature a new-generation smart grid that can help monitor how much electricity is being used at home, said the Bureau of Energy, which co-organized the event, in a statement Monday. The smart grid, if combined with the Internet and other systems, can help identify old home appliances that consume a significant amount of power and need to be replaced, the bureau said. The bureau will also display a motor driver that can enhance the efficiency of the equipment used to power freezers, vehicles or air conditioners, helping save energy as a result. The government has vowed to build 50 low-carbon communities by 2011 and six low- carbon cities by 2014 in Taiwan.
