I grew up in Germany not far from the dutch border and am an avid cyclist. My point is that at the time being you can produce far more efficiently solar energy with putting solar cells on roof tops and you are being ripped off tax payers money. Once you run out of roof tops there is not much of development needed to add a 1cm glass plate on top of a solar cell. It is not like developing a fusion reactor. You are legally stolen 2.7M€ because you can supply three house for just 30.000€.
