Solar PV actually anti-green energy? Is the bubble going to burst?

Its official. The solar bubble has burst. The hype on solar PV is finally being realised. It takes more energy to make solar PV generation than it actually generates back !
EROI ( Energy return on investment ) on the solar PV has been found to be not even 5.0



In India it matters most.Why? Because in ther recent past much of the MNRE budget and state govts' inputs and subsidies have gone into solar. The catch here is theta in India resources are so few that prioritization becomes impractical. WE have pushed solar PV ahead at the cost of wind energy !


Whats happening is like this. We consume 1 unit of ffossil fuel to generate 1 unit of solar energy. Net result? Zero if not negative.
