According to the National Venture Capital Association (NVCA), VCs are going to continue to pour money into Cleantech areas beyond solar and biofuels. There will be consolidation, more venture-backed IPOs and an eventual over-valuation of the sector. See the NVCA Report.
Will the sector really become over-valued though? With global demand increasing everyday from the emerging market – notably the drastic increases seen in the middle classes of India and China – it is very hard to state exactly where an upper boundary exists. Growth these days is not limited to the US, but it is measured in a global framework that is only beginning to be defined by newer business trends and strategies.
Global warming and energy reserves continue to be an issue that becomes more evident everyday. Until realizable change is evident, the cleantech market will continue to grow and expand at obscene CAGRs. We are only at the dawn of a new era in renewable energy and cleantech; hang on for the ride.
