Where would we find out about educational options for ‘Green collar jobs?”?

I am very interested in finding out about getting educated on
the different types of ‘Green collar jobs?’ Seeing that this is the
next ‘gold rush’ of the economy, I want to be on top of things
and get educated on jobs which are going to be hot and propel
us into the future of green america. Does anyone have any suggestions as to websites which may offer ideas?
