CNN Eco Solutions : Energy : Spain Solar Tower

Stupid Spain ( Europe) is not third country american farmer

Yes. The 82%. I don´t see the relationship. Envy? Times are changing dude.

INCONththththEIVABLE!!!

i think nuclear energy is actually really efficient and is now very safe and reliable

Because the wind stops blowing at night?

easy, immense black economy

Aint nothing third world about about nuclear power-its a rapid answer to a rapid problem.And with the development of fusion could well be the long term solution.

I'm afraid it's due to the financial crisis. Two years ago, before the credit crunch and the real estate bubble, the unemployment was 8%

I hope you are right. I think the 20% is from the power companies. They know how much energy they can handle from fluctuating sources.

Okay, that's a point, they have to be able to adapt to quickly changing input from fluctuating sources, and conventional power plants are quite slow in adapting, especially coal-fired ones. Wind power will be a problem, because electricity is hard to store and there can be rapid changes in output on certain days.
But as I stated before, new solar plants will have heat storage to run through the night. The new solar troughs in Spain have a 7.5h heat storage and can run this time at full capacity.
