Electricity to Food - Industrial farming indoors, improves yield 100-fold

This is what I call an Electricity to Food system.  Mostly self contained and isolated from the environment, you could grow food underground or in the desert and control water usage and air temperature.   But they never talk about powering the LED.

So if you use Solar, then it seems like a long way to put up solar cells only to turn it back to light to grow plants. 

That's why this is different then the solar elevated farms. 

I dread the thought of coal or oil to food using this technology.

If you thought the agricultural revolution was something that already happened, maybe you should think again: a scientist in the Miyagi Prefecture of east Japan recently converted an old semiconductor factory into the largest indoor farm on the planet illuminated by LEDs. Racking up 25,000 sq. ft. and 10,000 heads of lettuce per day (no, that is not a typo) even this early in the process, the superfarm could very well make outdoor agriculture a figment of history.

Point in case: Shimamura's indoor farm uses just one percent of the water consumed by outside crops. This is thanks to the advanced monitoring systems that are plentiful throughout the entire system. The farm is truly a science experiment at this point, not meant to get into the produce business, but rather the "changing the world" business. It may do just that -- plans are already being drafted to crop up more farms in food-starved areas of the world.

The innovative people at GE Reports have kept us well-apprised with a thorough article on the topic, and the topic surely warrants even more research. We may be witnessing a monumental discovery, as it occurs.
