RE Solar and Wind contributed 60% of total Energy of Germany on October 3!

Solar and wind energy contributed almost 60 % of the total energy at noon of October 3, 2013.  For the entire day, however, the REs only contributed 36% of the total energy of Germany.

It was windy and sunny that day hence the high RE - wind and solar contribution.  This is significant, since Germany is not as sunny as in USA.  I learned that in the PHL, wind is not working that well most of the time they stop, or cooperatives do not buy their output (no buy or take provisions in their contracts prior to their approval?)

Wind and solar power plants hybrid complement each other

Repost from Clean Technica | May 1, 2013

Solar and wind energy combine (hybrids) installation complement each other. Losses from shadows cast by wind turbine account for mere 1 to 2% loss.  It was previously thought that shadows cast by wind turbine account for losses. 

Solar and wind comlement each other:   solar works best in summer when there is much sunlight while wind works best in winter.  Solar works only at most 5 hours during the day when the sun shines;   wind can work when there is wind blowing even when the sun is not shining
