actually, this is exactly what i'm talking about. The energy
that seems free, but isn't.
We don't notice it now because we're tapping nature's energy on a
small scale, but here's what is going to happen:
1) dams : tapping water velocity upstream equates to a slower
velocity downstream. Slow-flowing water downstream could lead to
major ecological changes
2) wind turbines : tapping the airpower up stream similarly leads
to lower wind velocity further down. Can you imagine an area where
there is perpetually no wind?
3) solar power : if we errect enough solar panels to capture the
power from the sun, the energy normally reflected back out is cut
down. Greenhouse effect, anyone?
