Then why pay to subsidize the capture of the solar panel market? Seems an expensive pretense.

Because they want the manufacturing and sales, to then sell it to suckers who think it's the future of electrical generation...

No, it's not. Unless you have a new method to eliminate pesky things like sunset and clouds. Solar cannot and never will have the capacity to replace primary power generation stations that currently run on coal, gas, oil, and uranium. You couldn't even use it to black start a real power plant. It has its appropriate use cases. Primary power generation just isn't one of them.

Many companies are building grids that are able to draw power from geographically disparate areas, obviating that issue. The construction of a national grid even made its way into some speeches by both candidates last year. Never say never.

Solar power generation coming down in cost is wonderful. But that doesn't mean it magically goes up in capacity too. The MWH limits of solar is still very very low compared to fossil fuel, and trivial compared to nuclear. And averaged out over the course of a year, they only produce usable energy 30-50% of the time. The rest is cloudy days, and that pesky sunset thing. The article even says a good portion of coal's decline will be due to cheaper, more efficient, and higher capacity gas and oil fired plants. Solar hype as far as I'm concerned is a political joke. It has it's appropriate use cases. Primary power generation isn't one of them. But most people believe whatever an activist tells them they should believe.

The sun still sets. And pulling power from somewhere the sun hasn't set just makes less power available over there. The capacity simply isn't there no how you try to spin it.

...Unless you design excess 'flex' capacity. I'm not some tree hugger, but the age of coal is over. Sorry, railfans.

Continuing the above argument, I'd read this.

It goes a little further than that, Mr. RR. Try any stakeholder - employee, investor, and yes, railfans.

I'm not blindly defending coal either. That's not my point. Coal is eventually going to be over and done with no matter what. Oil and gas will be what does them in though. Not solar or wind.
