SPS vs. solar/wind/hydrogen debate (Long Post)

I have partially read your article (and saved it for future reference) and
it appears to reference a lot of very useful data on solar and wind power
as well as SPS. What bothers me is the assumption that environmentalists
are anti-space, anti-technology, and anti-SPS. I have a very strong
interest in space, and an equally strong interest in environmental issues
and do not find them in serious conflict. I don't know is SPS will turn
out to be a useful form of energy but I support the research that would
help us determine if it would be the case.
