“It is Europe’s first commercially operating power station using the Sun’s energy this way and at the moment its operator, Solucar, proudly claims that it generates 11 Megawatts (MW) of electricity without emitting a single puff of greenhouse gas. This current figure is enough to power up to 6,000 homes.”

Solar energy in TÜRKEY
Türkey has remarkable solar energy potential. But we can’t use our this potential. in last five years, we have been applied some solar applications. you can find some special applications in http://www.unienerji.com , http://yekarum.sdu.edu.tr
Türkey has bigger potential than germany but germany has used solar energy more than us. I think, it’s main reason is less promoting the development of solar energy in türkey than germany.
