Clean Energy Benchmark Is Natural Gas: Today and for the Future

By The Empowerment Alliance

Much has been said in recent months about America’s energy production and consumption. Specifically, which types of energy are optimal for today and — perhaps more importantly — for our needs tomorrow is a subject from town halls to coffee shop conversations and kitchen tables.

Bloomberg Intelligence’s research shows data centers, buildings filled with servers and other computing equipment for data storage and networking that supports operations and artificial intelligence (AI), could be responsible for as much as 17% of all U.S. electricity consumption by 2030. 

One data center can require 50 times the electricity of a typical office building, according to The Department of Energy.

As America wrestles with its future energy needs, this indisputable fact remains: Natural gas is the affordable, reliable and clean energy source that should serve as the benchmark by which all other energy sources are measured.

Consider:

  • Carbon dioxide emissions from electricity generation have declined 61% due to increased use of natural gas over other sources like coal, according to The American Gas Association.
  • The restarting of coal plants underscores the real issue, which is the need to build more gas-fired power plants fairly soon.
  • U.S. utilities and investors plan to add 133 new natural gas-fired power plants to the nation’s grid, according to S&P Global Market Intelligence data, by 2030.
  • Renewable energy sources can’t keep up with our growing energy needs.

A tale of two Heartland states

One community in Omaha, Nebraska, is considering restarting an old coal power plant. We understand the urgency here, but the neighborhood that has had some of the worst air pollution in the region should consider other options. 

The fact that they’re bringing a coal plant online in Nebraska illustrates the dire situation facing officials and energy companies with AI and the growing need for affordable, reliable energy for decades to come.
Here’s a better example from the neighboring state of Kansas, which is what The Empowerment Alliance (TEA) advocates should be happening nationwide.

Evergy, which serves 1.6 million customers in Kansas and Missouri, will construct combined-cycle natural gas plants — each with a 705-megawatt capacity — in 2029 and 2030.

A key takeaway comes from Democrat Gov. Laura Kelly, who said the plants would ensure reliable energy, including in emergencies or periods of high demand, like hot summer days. “As Kansas continues to transition to more sustainable energy, we’re doing it responsibly. These plants are much cleaner than traditional coal plants.”

We agree with Gov. Kelly’s rationale and we encourage other states with growing data center footprints, such as Ohio and Virginia, to follow suit.

Energy Security ARC

At TEA, we have a plan for our energy future called the Energy Security ARC. Natural gas is the obvious solution to our clean energy needs.

The two examples above underscore the crossroads that many communities, large and small, are facing regarding energy choices. The decisions made affect local jobs (165 new jobs in this city), and will have a direct impact on consumer costs for decades. 

So they shouldn’t be taken lightly, based on these facts:

  • The U.S. is the world leader in lowering carbon emissions, largely because of increased use of natural gas for electricity generation.
  • Increased use of natural gas for electricity generation is the top reason for power sector emissions reductions over the past 17 years — almost double the impact compared to renewables.
  • In 2022 alone, the shift to natural gas provided an emissions reduction equivalent to 156 coal-fired power plants operating for a year.

There are various practical options for energy, and those may include nuclear and coal. But natural gas is the clear choice when discussing affordable, reliable and clean energy. This pertains to millions of households, small businesses, family farms, factories and technologies still being developed.

Natural gas is America’s trusted energy choice — past, present and future.

The Empowerment Alliance was formed in 2019 to offer common-sense energy solutions that promote production and consumption of Affordable, Clean, Reliable natural gas. We believe that our nation’s energy independence is essential for America’s independence.

Claim: Artificial Intelligence can Improve Climate Models

Essay by Eric Worrall

If you have a possible missing variable problem, the solution is to add more arbitrary adjustments to your model?

AI Exposes Accelerated Climate Change: 3°C Temperature Rise Imminent

BY IOP PUBLISHING

AI-enhanced research shows regional warming will exceed critical thresholds faster than expected, with most regions surpassing 1.5°C by 2040. Vulnerable areas like South Asia face heightened risks, urging swift adaptation actions.

Three leading climate scientists have analyzed data from 10 global climate models, utilizing artificial intelligence (AI) to enhance accuracy. Their findings indicate that regional warming thresholds are likely to be reached sooner than previously estimated.

…

Elizabeth Barnes says: “Our research underscores the importance of incorporating innovative AI techniques like transfer learning into climate modeling to potentially improve and constrain regional forecasts and provide actionable insights for policymakers, scientists, and communities worldwide.”

Combining climate models and observations to predict the time remaining until regional warming thresholds are reached

Abstract

The importance of climate change for driving adverse climate impacts has motivated substantial effort to understand the rate and magnitude of regional climate change in different parts of the world. However, despite decades of research, there is substantial uncertainty in the time remaining until specific regional temperature thresholds are reached, with climate models often disagreeing both on the warming that has occurred to-date, as well as the warming that might be experienced in the next few decades. Here, we adapt a recent machine learning approach to train a convolutional neural network to predict the time (and its uncertainty) until different regional warming thresholds are reached based on the current state of the climate system. In addition to predicting regional rather than global warming thresholds, we include a transfer learning step in which the climate-model-trained network is fine-tuned with limited observations, which further improves predictions of the real world. Using observed 2023 temperature anomalies to define the current climate state, our method yields a central estimate of 2040 or earlier for reaching the 1.5 °C threshold for all regions where transfer learning is possible, and a central estimate of 2040 or earlier for reaching the 2.0 °C threshold for 31 out of 34 regions. For 3.0 °C, 26 °C out of 34 regions are predicted to reach the threshold by 2060. Our results highlight the power of transfer learning as a tool to combine a suite of climate model projections with observations to produce constrained predictions of future temperatures based on the current climate.

If I have understood correctly, they are essentially using the AI as a complex black box polynomial correction to their rather imprecise climate models, to try to squeeze out better answers. The polynomial is trained by comparing observed temperature data to model output, then the resultant amalgamation of climate models and AI polynomial corrections is extrapolated to try to predict future events.

The problem with this approach is it creates the illusion of accuracy, without actually knowing if greater accuracy has been achieved. An AI used in this way applies complex arbitrary “corrections” to input data, to generate a near perfect match to any data used to train that AI. But the AI knows nothing about the underlying physical phenomena. The AI might be able infer physical phenomena if it has enough data – or the AI could just make stuff up, especially if unknown critical input data is missing from the set of data which is used to train the AI.

AI does have a role in scientific analysis. In fields like drug discovery and complex optimisation problems, AI can produce excellent results.

But AI also has a well known tendency to go off the rails, to “hallucinate” false results.

An AI malfunction is not a problem if you can test the quality of the AI results immediately. But using AI to try to figure out how to correct climate models, where nobody will know for years or decades whether the AI got it right, then using those AI corrections to project future events, this seems a dubious use of artificial intelligence.

Magherally No 2 DCNN 9270 – A poor site amongst far too many equals.

54.35928 -6.19546 Met Office CIMO Assessed Class 5S Installed 1/1/1976

An unusual case study. Magherally is a small village in County Down, Northern Ireland. This site is rated as Class 5 S meaning its siting is adding up to a 5°C inaccuracy margin with additional issues relating to shading. Astonishingly the Met Office’s own unique rating system also suggests this site is “Excellent”. Looking at the image from the coordinates supplied by the Met Office the shading issue does not look particularly troublesome. Neither does the location look especially bad considering many much worse sites are often rated Class 4 or even 3. I would have considered this to be Class 3. A closer look was required.

This image is from July 2023 so what is so terrible about this site? Hard to make out but the screen is a measured 35 metres from the trees and in an open rural, flat site. Although there is no obvious enclosure there are also no obvious extraneous heat sources to cause problems. Looking further the screen was pretty much the same in back in 2016 but going back to the same viewpoint in November 2008 revealed it was not there at all.

The archives give no indication of a relocation so where on earth was it? Theoretically, if the move is not over an ill-defined distance and does not significantly alter the site’s likely readings, then renumbering is not required so presumably it was originally nearby. A tour around the maps and street-view finally found this quaint little nearby back garden site back in 2008……….Clearly Class 5 and subject to shade!

It appears that some time between 2011 and 2016 the site was moved approximately 80 metres from a back garden low grade location to a much better one but the Met Office have not since opted to update the CIMO site rating. Unusual for the Met office to underrate one of their screens or possibly an oversight as their own “Excellent” rating is their default setting. This site represents even more that is peculiar about the Met Office’s operations in Northern Ireland – it is notably worse than England, Scotland or Wales.

There are 28 currently operational CIMO assessed weather stations in Northern Ireland, 20 automatic and 8 manual reporting units. NONE OF THEM ARE RATED CLASS 1. Just 2 stations are rated Class 2 and one of those (Giants Causeway) is highly debateable. 2 stations are Class 3. 11 are Class 4, and 13 are Class 5.

In the entirety of a constituent country of the United Kingdom of Great Britain and Northern Ireland, the Met Office seems unable to find any premium quality sites…..is that really plausible?
