[p2p-research] does wind power obviate need for nuclear

[Ryan Lanham]

Michel:

There is more than enough wind.  Far more than enough sun.  We even have
more than enough geo-thermal.

The key is having smart grids to move power and means to store and transport
it.  Smart grids would cost trillions on a global scale.  The technology is
also not yet fully there.

So far the only real possibility for storage is hydrogen.  I am always
anxious to hear about others...ammonia is sometimes discussed.  Some places
may pump water to the top of a hill or building the way the Scots do.  To
move energy 10,000 miles requires something that combusts or runs a fuel
cell so far as I know.

If I had to predict an energy future, it will be large scale desal and h2
production from renewable energy...like this:

Of course the windiest places on earth on the oceans...
