Plant material accumulated over many millions of years, how is this relevant to renewable energy, clearly it isnt.
Prove its not a soundbite, provide some actual information and tell us what toxins your talking about.
This is not possible in an industrialized society with the population we currently have, or do you have some actual concrete suggestions, with facts and figures to back it up.
The very reason cities are warmer than surrounding areas is the lack of trees and other vegetation. Wouldn't it be nice if the cities were provided a style of engeering that includes space for many highly absorbative plants which when done growing be collected and burning for energy? Might the cities actually have a better environment and provide some energy instead of just using it up?
Plants that grow quickly tend to have a high content of water and as a result have a very low heating value, or even no heating value at all. You previously mentioned energy density in a post, wet biomass has the lowest energy density of allmost any fuel, and therefore the highest transport costs etc. Plant trees by all means if the evaporative cooling is going to cool your cities down, but dont pretend theyre going to be used as any significant fuel source. It would take more energy to cut down / dry / transport / dispose of ash than you would ever get from the plants.
These vague and woolly statements your so fond of may sound good to someone with no technical background but if your going to convince anyone else you need to back it up with verifiable facts and figures. There is allready too much of this airy fairy nonsense floating around the internet.
To be perfectly frank, some of what you say is so far removed from reality and said with such assuredness, that for me it calls into question many of your past comments as a result.
