Is There Such a Thing as "Green Forever"?

Feb 09, 2012

"It is clear that continuing to rely on fossil fuels will have catastrophic results, because of the dramatic warming effect of carbon dioxide. But alternative power sources will affect the climate too. For now, the climatic effects of "clean energy" sources are trivial compared with those that spew out greenhouse gases, but if we keep on using ever more power over the coming centuries, they will become ever more significant.

"While this kind of work is still at an early stage, some startling conclusions are already beginning to emerge. Nuclear power - including fusion - is not the long-term answer to our energy problems. Even renewable energies such as wind power will have to be used with caution, because large-scale extraction could have both local and global effects. These effects are not necessarily a bad thing, though. We might be able to exploit them to geoengineer the climate and combat global warming."

--New Scientist, in an article titled Power paradox: Clean might not be green forever (via WSJ)

Is there a "big think" solution to the effects of long-term human energy use? What do you think?
