Wind and solar will be promising industries in the Asia Pacific in 2010, Frost & Sullivan said, because of several advantages they have over other technologies.

The region holds abundant solar and wind resources, including the modular nature of the technologies, which allow for easy expansion plans.

Solar energy particularly is expected to enjoy growth as investors are keen to take advantage in a combination of declining prices, supply glut and government incentives.

Japan, South Korea, Australia, Taiwan, Malaysia and Thailand are expected to see solar growth potential in 2010. Meanwhile, there is likely to be ¡°pockets of interest¡± in Vietnam, the Philippines, Taiwan, Thailand, Japan and Australia for wind.

"Growth opportunities in these two sectors are likely to attract new entrants, such as small and medium enterprises, supplying components as well as companies that undertake system integration and installation," said Ms. Sriram.
