On display at the 200 booths are energy-saving products and equipment using advanced and environmentally friendly technology such as solar water tanks, solar batteries, and small hydroelectric plants.

Pham Duc Tien, Deputy Director of the Hanoi Department of Industry and Trade said the exhibition offers a chance for businesses in Hanoi and the northern region to promote investment, introduce their products and raise competitiveness.

It also creates a trading venue for domestic and foreign businesses operating in the energy and environment fields, while helping to raise public awareness of energy efficiency and environmental protection, contributing to renewing a growth model for green and sustainable socio-economic development, Tien said.

The four-day exhibition, the largest of its kind in Vietnam, is co-organized by the Hanoi People’s Committee, Ministry of Industry and Trade, Hanoi Energy Conservation Centre and Vietnam Association for Conservation of Nature and Environment.
