Concentrated Solar Power is dying out in the U.S.

Posted on June 12, 2020 by

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 →

Building a national super grid in America

Posted on June 3, 2020 by

Preface. Renewables are not evenly distributed.  Just 10 states have 80% of hydropower (Homeland Security 2011), 10 states produce 75% of wind power (EIA 2017), and 10 states produce 79% of solar power (CE 2020). With a national grid, instead … Continue reading →

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

Posted on January 20, 2020 by

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 →

Challenges to making California’s grid renewable

Posted on September 10, 2019 by

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

Posted on June 5, 2019 by

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 →

Challenges to the Integration of Renewable Resources at High System Penetration

Posted on February 2, 2019 by

Preface.  This overview of challenges for wind and solar written in 2010 is still true today. We are far from being able to reach even a 50% renewable grid (excluding hydropower from the total) given the lack of storage, the … Continue reading →

Robert Rapier: Oil demand is growing, not shrinking. There is no peak oil demand in sight.

Posted on July 4, 2018 by

[ Yes, this article was published 10 months ago, but with all the attention to fake news today, I thought it would be worthwhile pointing out that peak demand is propaganda, not based on facts. Since the goal of fake … Continue reading →

Can the lights be kept on with distributed generation? 2015 U.S. House hearing on a reliable electric system

Posted on April 20, 2018 by

[ Corporate speakers testify – could they have any self-interest, hope for government grants?  Since Congress often asks the National Academy of Sciences (NAS) to write unbiased papers on topics,  why didn’t NAS and National Laboratory scientists speak? Corporations are … Continue reading →
