Why wind and solar will cause more blackouts
Preface. Clearly fossil fuel plants need to be replaced with energy storage — batteries, pumped hydro, or compressed air. Many hours of backup power will be needed since, unfortunately, over two-thirds of total wind power in the U.S. happens outside … Continue reading

The Next Big Thing: Distributed Generation & Microgrids
Preface. Last updated 2022-9-5 The first article below explains what microgrids will look like in the future. But first a brief look at what a microgrid is, as Angwin explains in her book “Shorting the Grid. The Hidden Fragility … Continue reading
Concentrated Solar Power is dying out in the U.S.
Preface. Concentrated Solar Power (CSP) contributes only 0.06 % of U.S. electricity, mainly in California (64 %) and Arizona (24 %) because extremely dry areas with no humidity, haze, or pollutants are required. Of the 1861 MW power they can … Continue reading
Challenges to making California’s grid renewable
What follows is a report from the California Energy Commission. But in less bureaucratic language, this may summarize it better (Petersen 2019): “I’ve always been amazed at a strange mental disconnect that’s common among renewable power advocates. On one hand, … Continue reading

Black starting the grid after a power outage
Black starts Large blackouts can be quite devastating and it isn’t easy to restart the electric grid again. This is typically done by designated black start units of natural gas, coal, hydro, or nuclear power plants that can restart themselves … Continue reading
Can the lights be kept on with distributed generation? 2015 U.S. House hearing on a reliable electric system
Preface. Corporate speakers testify mainly, rather than less biased researchers from universities or national laboratories. Corporations are selling a product, and likely to exaggerate what their product can do. The most interesting testimony is from Dean Kamen, who is “selling” … Continue reading

Underground pumped hydro storage is the only technology capable of massive storage for renewable electricity
[ Picard concludes that “None of the candidate technologies for massive-scale renewable and sustainable generation of ‘‘green’’ electricity deliver it in a form suitable for high-efficiency storage. None of the prospectively-massive storage modes for transformed electricity is at present well … Continue reading
