Thank you for those suggestions ... I have saved your post and will look into the companies you mentioned.
I am holidaying (read ruining my knees skiing lol) in Canada at the moment ... I will find the time over the next few days to reply on the GREENE thread to post green energy suggestions for you.
The inter-relationship between food production and fossil fuels and the implications of peake oil and coal combustion carbon emmissions make disturbing sense and a plausible (if not sadly, opportunistic?) longer term investment theme.
I like your work and can appreciate your food themed investment conviction and patience.
