Access White Paper

Regions that have high penetration of solar and wind resources can experience an excess of energy supply, which drives down hourly power prices, particularly for renewables. This is a benefit for consumers, but the decline in market value can hurt producers, according to a new study from the Energy Department’s Berkeley Lab. 

The study tracked market value of energy and capacity produced by 2,100 utility scale power plants across major power markets through 2019.

Really interesting-- market structures definitely need to be carefully considered

Laurent, in 2015 Alex Trembath and Jesse Jenkins at the Breakthrough Institute published a seminal paper which hypothesized that the market penetration of renewables is limited to their capacity factors - in essence, once they exceed their capacity factors, solar and wind literally become worthless.

Why wind and solar eat their own lunch

It has been verified again, and again, in Germany, Denmark, California...everywhere. Yet renewables activists continue their religious crusade to force adoption of two sources of energy which are by definition, incapable of replacing fossil fuels.

Enough is enough - there's no more time to waste.

Indeed, Jessie Jenkins is a great resource in this area.  

Recently, he along with a large team at Princeton, published a massive "Net Zero America" report. Well worth taking the time to read.

Below is a slide showing the role solar and wind generation could play in the various scenarios.

Correction: he was a great resource in this area. Recently he, along with a large team at Princeton, succumbed to the lure of big cash from Big Oil and started claiming solar and wind could reliably power an electrical grid! But you knew that:

"Why would I waste my time reading a climate change study funded by Exxon-Mobil and British Petroleum?

"Students at the University regularly express wishes for urgent climate action and divestment. Previous divestment campaigns have garnered thousands of signatures and a recent petition initiated by University alumni has garnered 800 signatures as of this submission, with signatories vowing not to donate to the University until it divests from fossil fuels.

Fossil fuel companies now seek to rebrand, touting altruistic investments in renewable technologies and generous funding to universities such as BP’s $43 million and ExxonMobil’s $6.7 million donated to the University's [Princeton's] climate change research.Despite the shift in branding, investments in sustainable enterprises are dismal with only 1 percent of their budget spent on non-oil and gas projects. Meanwhile, the industry’s efforts to integrate themselves into University research helps to change the narrative and deflect blame from their own culpability. In fact, while the companies like BP claim to be interested in supporting research into climate solutions, they continue to politically thwart adoption of these same solutions."

You'd think Exxon and BP would be a little less obvious...took me all of 4 minutes!"

Nice try.

Love how you throw Jessie under the bus once he comes out with something that doesn't agree with your position. However, I doubt that will stop you from quoting his earlier paper without mentioning his latest work.

Same goes for Dr. Christopher Clack - at Vibrant Clean Energy - whom you often mention. Here is a recent report from VCE:

This is the Year Montana Decides how to Replace Coal

The results are startling. Because Montana is blessed with world-class hydroelectric generation, plus exceptional wind and solar resources, Montana can meet all its future needs, including peak loads in summer and winter,with clean energy. This transition can expand employment and increase energy exports to fill an almost insatiable regional energy demand via surplus clean energy.

I throw anyone under the bus whose primary motivation is not to address our worsening climate crisis, but to profit on fake solutions to it - including Jesse Version 2.0., whose salary is now paid by British Petroleum and ExxonMobil (laundered through Princeton University); including Chris Clack, whose company, Vibrant Clean Energy, has a mission that includes

"Maximiz[ing] returns from generation for the grid, the owners and the developers"

"Provid[ing] technology to facilitate efficient operation of generation, electricity grids and markets;"

whose "products" include

"WIS:dom®-P (Planning Model)

The flagship software product of VCE® for finding the lowest cost market solution for entire energy systems.

Resource Datasets

High-resolution (spatially and temporally) for wind, solar and grid topology. Historical, climate and reanalysis data.

Wind and Solar Forecasting

The VCE® novel solution to ever increasing forecasting costs using operational High Resolution."

blah blah blah...

Not sure what it is you don't understand about it, Joe. This is big business - it's all about selling the lie of wind and solar. It seems there are some who haven't figured out renewables are a scam, are snake oil - and others who have recognized the vast potential of profiting from their naïveté.

Like I said Bob - I look forward to the next time you quote studies from Dr Jenkins or Dr Clack.

I  understand why you have to - there are so few relevant experts in this field who support your position.

And...your position is anyone who's paid $$$ to say what they're told to say is "relevant", is an "expert"? Sad.
