Solar cheapest source of energy - in all 50 States! (and worldwide!)

Solar cheapest source of energy - in all 50 States! (and worldwide!)

Utilities often have the obligation to the public to draft an integrated resource plan (“IRP”) every 3-5 years to determine the cheapest electricity generation mix for their customers. The resulting IRP is subject to independent third party approval by the Public Utility Commission (“PUC”). NIPSCO is a utility in northern Indiana. In their most recent resource plan in October 2018, they evaluated 8 different scenarios from status quo (65% coal) to an almost zero emission scenario (0% coal). Coal was step by step replaced by renewables, mostly solar. The result is astonishing: The cheapest scenario for their customers was 0% coal, with lots of solar replacing it. In other words, new solar is cheaper than operating coal!

 

Solar - cheapest source of energy 

And even better: Have a look at the solar map for the US. Northern Indiana is green. And every state in the US is either green or even yellow and orange (more sun). 

 

In other words, solar is the cheapest source of energy in all 50 US States! Only wind energy can compete with solar.

 

What does it mean for the world? Well, let´s look at the world solar map. Same picture, northern Indiana is green, the world is also green and mostly yellow and orange – even more sun. Therefore, we can conclude that solar is the cheapest source of energy worldwide now! New solar is now cheaper than operating coal plants. Cheap solar is only competing with cheap wind energy. A remarkable finding. Actually a key finding, to make Paris work. Wind and solar energy have economics at their back now. Let´s go for 100% renewables! 100% cheap renewables!
