This is idiotic. Of course, fortunatly, even the most avid counter-
culturalist rejects this sort of nonsense. Try living in Virginia or
NY or the tropics without air conditioning.
People did (end even do) for hundreds of years. Try isolation, and using
more concrete.
That is possible. If you have 30% backup, you can predict the total
production, a day ahead.
30% back up of what? You can't predict wind a day in advance, you get
now power at night from solar. It's silly unless you want to start
producing billions of lead acid batteries.
Why is wind power not allowed to use back-up. In Europe, eventualy gas
generators are use to fit the last bit of power to the demand.
And yes, if you really want electricity all of the time you need a local
back up (batteries, or diesel generator, or whatever). I understand
power blackouts aren't that uncommon in the USA (in the Netherlands we
had three big ones in the last year)
They used to claim the max is 10% until Danmark and Germany reached 20.In the end, it al depends on fuel prices. Wind is cheap, and becomes
cheaper as fuel-prices rise. Four years ago, I was told that 3MW
(nominal) power wind turbines produce cheaper as a coal-plant. When the
producers get their production-capacity in order, we will see bigger
(and more cost effective) turbines everywhere (where the wind blows).
But it's not predictable and any expansion of wind power over 20%
requires on damand back up...so what ARE they doing? They are
building more coal plants, obviosuly. So...wind is nicely backup with
polluting fossil because they have to have it when the wind doesn't
blow. The reality is that whole of Europes "wind" power rests on
cheap, very cheap French nuclear exports.
One could say, all electricity producers have to be helped because of french
electricity dumping (they do sell for less than the cost).

Frank
