Students as debt slaves, more of an indication of social breakdown. Meanwhile, “What Medicare for All is to the health care debate, or Fight for $15 is to the battle about inequality, 100% Renewable is to the struggle for the planet’s future.”

Excerpt from Students as Debt Slaves, at CommonDreams.org 23 Apr 2018.   Interview those fifty-ish high school educated male workers whom Ann Case and Angus Deaton revealed are dying prematurely from diseases of despair. In a meticulously documented essay on the origins and purpose of money, University of Missouri-Kansas City economist Michael Hudson points out that historians and anthropologists can find no examples of …

Supercapacitor-based energy storage for microgrids avoids over-sizing. Micro-grid engineering becoming a macro profession.

Supercapacitor-based energy storage, on the other hand, is much simpler. This technology stores energy on the surface of the electrolyte, which means there is no chemical reaction. “Electrical energy comes in and is stored as electrical energy. It releases electrical energy back into electricity when discharged,” Ghani explained.   Still supercapacitor-based energy storage hasn’t been used before because it has its …

Bloomberg reports that the combination of solar power plants and grid scale battery storage is now cheaper than natural gas and utility companies all across the US are starting to notice

February 15th, 2018 by Steve Hanley, Clean Technica  First there was coal. You burned it to make steam, then the steam was used to turn generators to make electricity. For more than a century, coal was the power that made electrical energy possible for most of the world. But coal has a problem. When it burns, it releases massive quantities of carbon …
