A record 138 of you voted in the latest month’s Clean Break poll, which asked “What cleantech area offers the biggest potential payback for investors?”
Is it a surprise that solar PV/thermal related investments got the most votes — 40 per cent to be precise? Surprisingly, wind came in second with 20 per cent of votes, followed closely by biofuels with 17 per cent. I would have thought that biofuels would have been a close second to solar, given all the talk in the U.S. about independence from oil and all the venture capital investment flowing into the area. Battery technologies came in fourth with 15 per cent of votes. Another surprise. I would never have guessed that batteries would be behind wind, what with all the attention these days to hybrid-electric cars (plug-ins as well), pure EVs, and the need for utility-scale energy storage and better backup storage.
I have to say I’m also stunned that investment in water technologies ranked so low at just 5 per cent of votes. This is the sleeper. If we think energy is the big crisis today, just wait until countries begin to be invaded for their water resources.
