Not to mention Drax, the UK's most visible bit of renewable stupidity. Still, stupid priorities will lead to stupid outcomes.

Those biomass plants need to be burning plastic waste, not trees!

 

[GregLocock]

Yes, I'm not wild about burning plastic for heat, but it beats burying it in landfill, kindasorta.

The only problem with burning plastic for energy is that plastic is a petroleum product, so that's also burning fossil fuels. Therefore, the 'green energy' crowd will be against it.

 

[TugboatEng]

All of those facemasks would make an excellent fuel. Their blown filament construction and breathability will promote more complete combustion and they are of polypropylene construction which doesn't produce acid gasses when burned.

 

[dik]

I hope they are correct, but I think this is just a marketing ploy to make more money...

"In a surprising shift within the energy industry, major fossil fuel players are boldly asserting that natural gas will play a pivotal role in the transition to a greener future, Bloomberg reported. Industry leaders such as Shell and Chevron are ramping up investments in natural gas, challenging the perception that it is a short-term bridge to renewable energy sources. This shift marks a turning point for natural gas, once seen as a temporary solution. Now, gas demand is expected to persist for decades to come."

I guess we'll have to wait and see...



The problem with sloppy work is that the supply FAR EXCEEDS the demand

If we're talking about replacing Coal Power with Natural Gas, then it's probably the most cost effective way to reduce CO2 emissions today. But, that REQUIRES that we shut down those coal plants. Otherwise, it's just adding more power to our grid (which might also be necessary).

 

[BridgeSmith]

Many power plants in the US have been converted from coal to run on natural gas. So far, because of fracking, the gas supply has been keeping up.

 

[dik]

I don't know how CO[sub]2[/sub] output per BTU is for coal vs. natural gas or oil is. The switch from coal may not be any better if it has a higher BTU rating for the same CO[sub]2[/sub]. Coal is just ugly, and more visible. It is a political issue too, to prevent doing anything about the carbon footprint.

None of this is good...

This is not according to the numbers; the world is still using more coal... when you consider the population of China is 5x that of the US. That would put the US at 1.5 compared to China's 1.05... Both numbers should be on the otherside of the vertical line (ordinate), like Australia... they, however, may be selling the stuff to others, and are maybe not any better.

[TugboatEng]

Dik, natural gas emits 41% of the CO2 of coal per MWh on average. However, combined cycle power plants can run on natural gas and are substantially more efficient than conventional so as more of the conventional gas plants are replaced my combined cycle that number can go even lower.

 

[dik]

Thanks, didn't know that... then natural gas is not the worst of the fossil fuels.

[TugboatEng]

In terms of carbon it's far from the worst, it's the best. It's mostly comprised of methane which has a 4:1 ratio of hydrogen to carbon. Anthracite coal is 1:2.7 hydrogen to carbon.

 

[JoshPlumSE]

Yeah. It's like 1/8 or less the amount of carbon. It's even better when you consider environmental pollutants. Because natural gas burns so darn clean. CO2 and water and that's pretty much it!

If you had natural gas cars it would be a LOT more difficult to get carbon monoxide poisoning in your garage.

More disruption with unknown effects. More acronyms...

"A large-scale atmospheric phenomenon is currently changing its phase high in the atmosphere. Called “the heartbeat of the atmosphere,” it has a known effect on the Winter weather and will combine its influence with the El Nino event to impact the weather patterns in the 2023/2024 Winter season.

This atmospheric phenomenon is called Quasi-Biennial Oscillation (QBO short), a changing wind anomaly in the tropical stratosphere. Its presence has been well known for many decades, and it plays its role in the Winter season pattern development."

I thought we had finally made some progress.

"Never let perfection be the enemy progress".

 

[dik]

and people still die of CO failure from heating systems, too, even with natural gas. Albeit, fewer of them.

Sorry Tug, the CO[sub]2[/sub] hasn't peaked, yet. I don't see any progress. Things may still get a lot worse. Texas may be experiencing the beginning of something that could get a lot worse.
