In my inbox from a campaigner in Spain

"Yesterday wind power broke all previous records in Spain. Because of high wind conditions, we reached 9563 MW of generated power at 15:27 (from a total installed wind capacity of 13908 MW). Wind power met 25% of demand at that hour, well above coal (15%) and nuclear (16%). A new record may be expected today.

You can see the graph in the following press release from the grid operator REE: http://www.ree.es/sala_prensa/web/notas_detalle.aspx?id_nota=53

And real-time wind generation from the same source:

Now some sceptics will say that you can't rely on a power source that only works when the wind is blowing, and they'd be right. That's why a piece of research by German researchers is so important. They've shown how a portfolio of different renewable technologies can be combined to reliably meet Germany's entire energy demand. Read about it - and watch the YouTube explanation here"
