$this->bbcode_second_pass_quote('davep', ' ')I don't think using solar energy equates to NPP at all. We would be using an insignificant level of world total insolation. There is a slight risk of temperature rising due to harnessing the energy that may otherwise be lost back to space. This vanishingly small compared to other factors such as melting ice caps.
Didn't say it did. NPP relates to photosynthetic production, but it still is part of the solar energy stream that flows through nature.
And insignificant?
That's what they said about dumping wastes into the rivers, or pumping CO2 into the air.
This man thinks it wouldn't be "insignificant."
$this->bbcode_second_pass_quote('', 'S')imilarly, if humans divert a fraction of solar energy away from the environment to create ordered structures for their own purposes (i.e., houses, appliances, transportation infrastructure, communication systems, etc.), less energy is available to maintain highlyordered dissipative structures in nature. The disturbance of these structures translates into the various environmental impacts that are associated with renewable energy generation.
