I'm a huge fan of renewables. Basically the technology is hear to go 100% green. What's really missing are big government incentives to speed up the process. That's something that really makes me sad.
There is nothing wrong in supporting the renewables. But you must be ready to pay the price. For example, electricity from the thermal power plants cost around $0.03 per KWh. The same from solar panels cost at least $0.10 to $0.20 per KWh. Are you ready to pay the increased price?
The advantage of PV is that it releases up to one order of magnitude less toxic materials (production, while in use and recycling).
Additionaly PV cost decreased by several magnitudes (70s: 70$ per kwh; 2015: 0.30$ per kwh) while c.o.p. increased by a factor of 5-8 ( 4-5% to now up to 25%. Special designs go up to 40%).
And the development is still ongoing and not finished. We will see much better stuff for less $ in the future.
