RenewableEnergyWorld.com's Meg Cichon spent the week in Hong Kong at the 2011 Eco Expo Asia. When the event wasn't showing off the latest cleantech gadgets, it was advocating residential renewable accessibility and the importance of a vibrant trade market. It is widely known that Hong Kong and much of developing Asia suffers from heavy pollution; this fair offered valuable solutions to combat the problem – and renewables play a big role. International companies were present and eager to ship their solar panels, wind turbines or biogas systems, offer development services for residential systems, or simply educate attendees. The most impressive and promising displays were from Hong Kong utilities, such as CPL, that highlighted a renewable future and efforts to transition into the clean sector. As a whole, the expo was a refreshing display of the international effort to promote a clean energy future.
