The fact is, we are on the cusp of another huge leap for mankind, it's happening now. We have to get the best minds involved with this, to ensure it's good, and right.Quote:

There are several reasons why this isn’t surprising. Wind should continue to be the No. 1 fuel source in future years.

Won’t all the wind turbines bring the earths rotation to a halt??? [emoji6]
no, they are aligned to spin the other way, so the earth rotates faster, hence why the days feel shorter.Quote:

Fully agree we flip flop and also toss grenades at things we do not like [thumbsupbig] The Texas freeze is horrible for them. People dying from it so not meaning to be offensive or light fires on the topic.Quote:

D.O.E. in the US just put a USD$20million grant to study Nuclear/Hydrogen production. Using spare off peak Nuclear capacity or cheap wind/solar/hydro is really a no brainer I feel. While battery storage is fine and getting all the publicity. The Biggest battery is a few minutes worth and as Texas is proving a few minutes is not enough there or anywhere.
Have a great day all
The principal reasons for the power collapse in Texas is a combination of factors. Dependence on renewables is not one of them, despite what Governor Greg Abbott says. Renewables only represent a small fraction of the output lost (a couple of GW out of a demand of up to 75GW.
Major factors:-
1. Texas grid is not connected to the two main North American Grids. This is partly for historical reasons - with few large cities close to borders there was no reason to interconnect (several cities close to the border are not on the Texas grid, but connected to adjoining states and hence to the main grids). But it has also been pursued simply because Texas did not want Federal controls that could apply to interstate commerce.
2. It does not normally get this cold for this long in Texas, and the power stations are not designed for this sort of weather - they are designed for hot weather. 25% of nuclear power and about 10% of thermal power shut down because of cold effects including ice choked water inputs and control systems failing or going into limp mode because of the cold. And about the same proportion of wind turbines were shut down because of icing - no deicing "because it is not normally needed", but these only represent a tiny fraction of generating capacity lost.
3. Peak demand is in summer, so maintenance is in winter - a number of power stations were shut down and could not be easily restarted. Demand, if they could have met it, would have set a new record.
4. A shortage of natural gas - production seems to have dropped by about 50%. In part this was due to record demand, but also because some production facilities failed due to the cold (most gas comes from the ground with a bit of water mixed with it. This is separated at or close to the wellhead so that it does not potentially form methane hydrates that can block the pipes, but in this weather it seems some of the pipes became blocked before the separator. This gas shortage was exacerbated when some generators shut down as the spot price for gas went up by as much as 10,000%.
5. Most Texans have no concept of energy conservation - for example, for the first two days of the energy crisis, all the unoccupied buildings in downtown Houston were fully lit. It is not clear whether the owners eventually got the message or the power companies just cut power to them after that.
6. Total lack of leadership for the state - the most prominent senator was filmed heading for Cancun with his family, and the Governor had nothing to offer. As early as Sunday the demand was expected to go to close to 75GW, but generating capacity was only expected to be about 55GW - and that was before plants started to shut down because of the cold. But it seems that nobody outside the power industry paid any attention.
I have been following this in detail because I have a brother living in Houston (he is sort of OK - power is back on, they are still alive, but water pressure is very low and there is a boil water directive, but unlike a lot, they have no burst pipes. They are short of food, and so are the supermarkets, but have enough to not starve. Roads are not yet safe due to ice.)
Renewablw energy misinformers are on the rise, especially now google and Sky have joined up. Another furphy was that Germany had no renewable energy because of winter.Quote:

Nothing is “broken”, there aren’t 30,000 idle turbines, and of course fossil fuels are still present in Germany’s energy system.
Data provided by Ember Climate show Germany’s hourly generation up to the end of January, and it’s clear that there were no stretches of “idle turbines” or offline solar – generation was above zero for every day, for both technologies. Wind power contributed between 5% and 55%, across January."

The prize for misinformation must go to the Texas governor Greg Abbott. Apparently, shortly after telling the state that the primary cause of the grid collapse was the failure of 30% of the gas, coal and nuclear power due to the effects of low temperatures, he was on Fox News telling the audience that the failure was due to the wind turbines icing up.
