Category Archives: Electric Grid

How the electric grid works is important to understand they myriad ways it could fail, including lack of maintenance after deregulation, the essential role of natural gas as the backup since batteries, hydropower, and compressed air storage can’t be scaled up, the difficulties in setting up a smart grid, or a distributed grid and more

Wanted: Math geniuses and power engineers to make a renewable grid possible

Figure 1. OPF solution of original seven-bus system with generator at bus 4 Preface. The U.S. electric grid produced 64% of electricity in 2019 with finite fossil fuels, and another 20% from nuclear power. Since fossil fuels and uranium are … Continue reading

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

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

A 1-year blackout could kill 90% of Americans

Preface. What follows is the 30-page testimony of Dr. Pry at a 2015 U.S. House of Representatives session that I’ve summarized. One of the ways that an electromagnetic pulse (EMP) could be generated is by a solar flare. During the … Continue reading

Generating electricity with biomass at utility-scale in California limited to direct combustion in small 50 MW plants

Preface. It’s obviously much easier and more energy efficient to set logs on fire for heat and electricity than to turn them into ethanol.   Burning biomass can’t do much to solve our energy crisis.  To produce just 10% of … Continue reading

Why self-driving cars may not be in your future

Preface. Below are excerpts from several articles about why a completely automated vehicle is unlikely.  Heaven forbid they are invented. Researchers have found that people will drive 76% more miles, stop using bicycles and mass transit, waste a considerable amount … 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
