I have a dream about solar panels everywhere: over car parks, on top of shopping centre roofs, over garages, on house roofs, all feeding 100% clean power into the grid and eliminating the need for coal.
And it's happening -- in India. And not because of subsidies or incentives but simply because solar panels are now so cheap they pay for themselves in 3 years. Remember, though there is a tiny (0.5%) annual drop in output as panels age, basically they will last at least 25 years. So there will be 22 years of completely free electricity. The Indian power gap will likely be filled by solar, not coal.
Disclaimer. After nearly 40 years managing money for some of the largest life offices and investment managers in the world, I think I have something to offer. These days I'm retired, and I can't by law give you advice. I do make mistakes, but I try hard to do my analysis thoroughly, and to make sure my data are correct. Remember: the unexpected sometimes happens. The expected does too, but all too often it takes longer than you thought it would.
The Goddess of Markets punishes (eventually) greed, folly, laziness and arrogance. No matter how many years you've served Her. Take care. Be humble. And don't blame me.
