As lovers of green gadgets, EcoGeeks probably know as much about what's new in clean technology (a.k.a Cleantech) as anyone on the web.  So if you're an EcoGeek thinking about investing in companies which make the technology you know and love, you will probably take comfort in the old adage that you should invest in what you know. 

An EcoGeek investing in clean technology companies will have an advantage understanding how a company makes money, and what is a needed innovation with a large  market,  and what is simply a bizarre curiosity.  More importantly, an EcoGeek knows that any maker of EVs will have to cope with endless competitors, and they're the first to know when LED bulbs are bright enough for general use.
