Texs Electricity Power Failure. Some Lessons can Be Learnt Here.

The Texas ice and snow has high- lighted some power supply problems. Like going off the main grid and going it alone.

It'll be interesting to see how they weatherize the equipment when snow covered the solar panels and ice built up on the blades of the windmills.

'Big Joe' might drive down to Texas in his Tesla to show them how it's done.

Texas relies on 51% gas, 23% wind and 13% coal.

The state largely relies on natural gas for its power supply, though some comes from wind turbines and less from coal and nuclear sources. Natural gas can handle the state's high temperatures in the summer, but extreme cold weather makes it difficult for the gas to flow to power plants and heat homes.

They are not connected to each other and cannot interconnect to help each other during black outs.

This is interesting . Planetcare will like this coz it knocks fossil fuels to some degree while not letting Renewables of the hook

Currently in Texas windfarms are not producing any electricity. The blades are covered in ice, leaving them unbalanced. Fuel burning helicopters are spraying them with hydrocarbon based antifreeze on carbon based epoxy windmill blades.

It's all very interesting the amount or lack of info that's being filtered through to us,research research and research.

where ever you may be ,let your wind go free

I guess Texas is not usually covered in snow and ice so they were not prepared for current conditions. and so almost all of their power supplie systems have failed.

It appears that these power companies may have skimped on infrastructure and not planned for extreme weather events?

Y'd reckon anybody could tell that the North Pole icecap is moving and will reform over America & the South pole is moving towards Australia.
Would I kid you?! Would I yank your chain?! Would I pull yer leg ?!  Maybe linked to the moving magnetic poles....Maybe not??

The wandering (Of the magnetic poles) has generally been quite slow, around 9km (6 mi) a year, allowing scientists to easily keep track of its position. But since the turn of the century, this speed has increased to 30 miles (50 km) a year. The south magnetic pole is also moving, though at a much slower rate (6-9 miles, or 10-15 km a year).

Blimey maybe the swallows will not be able to find their way back to Africa & no wonder the blooming pigeons are getting lost.

It would seem these very cold events are becoming more prevalent. Every northern winter seems to bring stories of snow and ice where snow and ice were once unusual but more common now. Snow on the Sahara sand dunes sounds ridiculous but it happened last year or thereabouts. Snow in Florida seems equally silly but it is happening. News yesterday was predicting Japan might be next for the big freeze. Not only are these big freezes becoming more common they are becoming colder than ever before. Maybe the movie The Day After Tomorrow wasn't set so far in the future after all. Thank goodness for global warming otherwise it might be much worse.

That was a joke....right..?

A rellie in Texas, in very cold weather leaves the tap dripping so water flows thru the pipes then water does not freeze/expand and later causes leaks. No power so dripping tap did not work. Re located to a hotel with family, filled up the bath with swimming pool water so after toilet use filled up the water closet up with a bucket of water from the bath. Ditto above re ice on solar panels and wind turbines NBG and power problems. Icey roads so cannot get to work in a major hospital and lots of serious cases because of road accidents.

Global warming will make some places colder due to the slowing down of AMOC which is happening.

Oh, of course. How silly of me to not know that hotter makes it colder just like a refrigerator.

Coal-fired electricity generation is a five-step process: Thermal coal (either black or brown) that has been pulverised to a fine powder is burned. The resulting heat is used to turn water into steam. The steam at very high pressure is then used to spin a turbine, connected to an electrical generator. The steam is then cooled, condensed back into water and returned to the boiler to start the process over......Hmmmm, Sounds a bit like Renewable energy aye?

So what happened? Pulverized coal burns bloody fast and hot. Did the water supply freeze,did the turbines freeze..(They are in a building and should not freeze,)? plus they are driven by stinking hot steam under pressure and the heat generated by a spinning generator and turbine is a tad warm.
If the water supply froze then the pipes were not insulated. Why would it freeze when the flow is so great and fast?

planetcare is a science denier,

According to currently accepted philosophies, science is a set of falsifiable theories. That's all it is. No more. No less.

He ignores the first and second laws of thermodynamics and the Stephan Boltzman law (the real science).

His quotes of peer reviewed papers are opinions not science. His overwhelming number of scientists (on both sides) are not science.
Albert Einstein is not science but his theory of relativity is.

Learn your science PC.

Global warming is based on the known physics of a greenhouse gas and the predictions that can be made from this and then tested by observation. The predictions made by the greenhouse effect have verified by an enormous amount of data. Also the overwhelming consensus amongst practicing and publishing climate scientists is that rising levels of C02 are warming the planet. Every Scientific academy also agrees that AGW is occurring. Global warming also does not conflict with the laws you quote!

Blah blah blah. Don't ever try to reason with Doug, he will bury you with links and dazzle you with psuedo science.

Give me one example of any climate psuedo science i have posted! The issue of global warming is not about reason its about evidence and coming up with a theory that can account for the all evidence and observations!

The problem here with global warming is that, it is questionable/debateable by the sciences as well as those of governments, as to the exact cause or a combination of causes contributing to what the world is experiencing in todays times. We know CO2 emissions are increasing around the world with each passing year, but is a combination of what our planet is undergoing in way of change, as is man in way of contributing to CO2 emissions into the atmosphere. Less more safe/practical solutions can be found to address the current global weather changes taking place, people will continue to pay a hefty price.
You heard the saying Rome burned whilst Nero played music, then let me say, whilst the sciences/politicians are juggling theoretical facts/figures as to what should be done, not hesitating in passing the blame from one to another in times of disaster, at the end of it all it comes down to this: Like a sinking ship, swim for dear life, for you can bet on it being, every man for themselves (& that includes the Captain of the ship)

The rise in atmospheric C02 currently about 3ppm per year is almost all coming from the burning of fossil fuels as the changing mass isotopic ratio of atmospheric C02 shows.

So the 7.6 billion people breathing out one kilo per day of CO2 pp makes no difference. Or the mountains that pour more CO2 a day into the air when they erupt than all the coal emits in a year???

The isotopic ratio C12/C13 of atmospheric C02 is becoming enriched in C12. Fossil fuels are enriched in C12 compared for example to volcanic C02.
Volcanic C02 or C02 from other sources is small compared to the C02 generated from fossil fuel burning.

Read them then you might learn something factual about climate change and its causes rather than the ill informed nonsense you continually post on this topic!
