Calling them out on idiocy, of which you opine them...tsk, tsk.

I'll grant you it's not solely solar, but renewable energy is already contributing over 14 percent to the electricity supply in Germany. GP advocated common sense. It seems to me that common sense would advocate applying solar power in conjunction with every other renewable energy source under the Sun to come up with something that meets or exceeds power generated by non-renewable energy sources.
