California Blows It Again

by W. Eschenbach, Fab 3, 2025 in WUWT


Encouraged by the reception of my previous post “Eight Ten-Thousandths Of A Degree Per Gigaton“, which ranged from warm acceptance through amused contempt to outright hostility, I’ve expanded my research to analyze the CO2 emissions of the late great State of California.

In my post linked above, I found that IF the IPCC is correct (which is a big “IF”), for each gigaton (Gt) of avoided CO2 emissions, there is an avoided global warming of 0.0008°C. Please read that post for the detailed calculations.

And utilizing that relationship, here are the past and projected future California CO2 emissions.

WOW! For all of our sacrifices here in California, for all the money we’ve spent and are projected to spend, we MIGHT cool the world twenty years from now by 0.006°C … be still, my beating heart …

Now, as to how much that has cost and will cost, the numbers are hard to come by. Here are some major costs:

• The California solar mandate is estimated to increase the cost of newly constructed single-family homes by approximately $8,400 each. There are ~ 60,000 new single-family homes built each year in California. That’s about half a billion dollars per year for the next 20 years until 2045, or $10 billion total.

• The “Renewable Mandates” and rooftop solar subsidies have made current California electricity about $0.15 per kWh more expensive than its neighbors. Average since 2004 is about $0.10 per kWh more expensive. California’s annual electricity consumption in 2023 was approximately 287,220,000,000 kWh. That’s a cost of $35 billion per year times 20 years (2025-2045) equals $700 billion, plus $29 billion times 20 years (2004-2024) gives a total of $1.3 TRILLION. And that’s with the totally unrealistic assumption of no increase in either consumption or electricity costs.

Les émissions de CO2 augmenteraient de 50 % d’ici 2030 si les centrales nucléaires fermaient

La fermeture des centrales nucléaires belges pourrait entraîner une augmentation de 50% des émissions de CO2 liées à la production d’énergie d’ici 2030, selon le professeur d’économie Johan Albrecht (UGent – Université de Gand), qui est également membre de l’institut de réflexion Itinera. Cela alors que le gouvernement fédéral et les entités fédérées doivent négocier dans les semaines à venir le Pacte énergétique, qui doit fixer l’avenir de la production d’électricité en Belgique.

Methane Emissions: from blind spot to spotlight

by The Oxford Institute for Energy Studies, July 2017


Very comprehensive file, 39 pages .pdf

Methane emissions influence but do not undermine the environmental case for gas. If the industry can build on the progress to date and deliver a clearer picture on the level of emissions and actions to address them, the arguments for gas displacing coal in power generation and oil products in transport become much stronger.
