1.7% of the US land area seems to be dismissed as an significant or
readily-achievable amount. By my estimate that's about the size of Vermont
and New Hampshire combined, perhaps even more. And then it is suggested
that to supply our power needs with nuclear would require a reactor every 30
miles, probably hoping the distinction of "coastline" will be lost in the
discussion, or if not, drag in the idea of ruining the coastline. This is
not a report - it's yellow journalism.
Interesting too that the waste from the nuclear plant is described as
problematic, but there's no mention of waste from producing the solar
panels. The manufacturing process generates some very nasty waste, and
since the average lifetime for solar panels is short enough that a large
system would require a continuously operating replacement process, a large
scale solar program will involve a continuous waste stream.
No one has been able to produce panels with a long enough average lifetime
to produce more power than they take to manufacture, so it can't work
anyway.
The ultimate factor in my opinion is the one that is crushing Germany right
now - any power system that does not consume a fuel of some sort cannot be
made to produce power on a schedule. So Germany's heavy reliance on wind
power means that 12,000 MWe are missing from their grid because the wind
farms are becalmed. You can't control WHEN you make power unless you
control the source of the power. So unless Greenpeace has a plan to control
the sun and the wind....
Other than that, it's a great idea.
