The list, according to Cleantech Group, is an annual barometer reading of the global innovation community's shifting views on which companies, and the type of clean technology sectors, are most likely to have big commercial impact in a 5-10 year timeframe.
According to the report, energy efficiency remains the hottest and growing sector within cleantech. Within this category, lighting and enterprise energy management solution (usually for buildings management) are the dominant sub-sectors.
Since the list's inception three years ago, companies focusing on green chemistry still remain underrepresented among overall clean technology sectors but the good news is that mainstream media is now recognizing the importance of the chemical/ advanced biofuel sectors.
