The 2nd International Exhibition for Renewable and Decentralized Energy Solutions (ENEREXPO Vietnam 2012) will open here on Wednesday, attracting companies from 11 countries and territories, announced the Ministry of Science and Technology (MoST) on Monday. During the 3-day expo, co-organized by MoST and German Messe Munchen Group, participants will focus on three major topics, including markets for renewable energy - at present and in the future; renewable energy technology experience and lessons; and opportunities and challenges in the field of renewable energy. They also discuss on solutions including solar energy, wind energy, hydroelectric power, bio-energy, thermal-geo energy, power transmission, and decentralized energy supply. The event expects to provide an opportunity for domestic and foreign investors in the field to exchange information and advanced solutions on renewable energy, and to expand their business. Domestic managers, scientists and businessmen can update the information about technologies, equipment and solutions by other countries worldwide, as well as seek their partners, said Deputy Director of MoST\'s National Department for Scientific and Technological Information, Le Thi Khanh Van. On the sidelines of the expo, seminars and conferences will be held to introduce visitors with new technologies and experience for development of renewable energy, improve awareness about the important role of selecting technologies suited to the acceptance capability, and skills on preparing documents and negotiating contracts on technological transfer to avoid risks during the transition process.
