Yes but more expensive than coalIs gas quicker to build?
Yes but more expensive than coalIs gas quicker to build?
To rephrase more expensive as base load, is easier to start stop to follow the wimps of solar/wind erratic production or absence of..Yes but more expensive than coal
1. Engineering and economics has given way to politics and ideology as the basis for decision making.
2. The industry focus has shifted from cost minimisation to revenue maximisation.
That's it really. Fix those two points and the rest just goes away.
I think so, i am afraid.and it will hurt for a while as there are no overnight solutions ...What can bring about that change ?
Only disaster I'm afraid as you have previously mentioned.
Well that didn't last long.China has built a 20MW wind turbine, that is amazing IMO.
The largest turbine in history is turned on in China: It shouldn't be causing this
China turns on the biggest turbine in history. This shouldn't be the result of it. It has the potential to generate power for thousands of households.www.eldiario24.com
On August 28, Mingyang Smart Energy, a maker of wind turbines, installed this 20 MW clean energy source. The turbine from Mingyang has been thoughtfully engineered to resist the wrath of typhoons and flourish at medium-to-high wind speeds. Itâs interesting to note that it can tolerate winds of up to 79.8 m/s. It is definitely one of the strongest and best-built wind turbines so far.
Experts, however, are observing unexpected consequences that raise questions about the wider impact of such large installations, even though their capabilities are revolutionary.
The unitâs design is lightweight and versatile. The turbineâs generator, gearbox, and other vital parts are housed in this enormous nacelle. The turbineâs rotor diameter, which ranges from 260 to 292 meters (853 to 958 ft), is interesting. âA maximum swept area equivalent to nine soccer fieldsâ is reportedly covered by this.
Yes gas is a lot quicker to build, but as numb nuts IFocus seems to be forgetting, gas causes emissions and in reality has to be replaced by 2050 also.Is gas quicker to build?
You really are thick, aren't you, you don't seem to understand that gas is a pollutant and seen as a stop gap solution until renewable/storage, or renewable/nuclear give 100% clean energy.I'll try and help you out here... nuclear, gas and renewables... how long did you work in the area?
The nuclear so called plan requires dam near as much gas as just renewables
Meow...
Carry on.
I'll avoid personal comments but this is a key issue.The other issue is gas isn't an endless resource
The other issue is a large portion of the population now have an expectation that fossil fuel is going to be stopped, turning that momentum around wouldn't be easy.I'll avoid personal comments but this is a key issue.
At the global level about 10% of known gas reserves are in Western countries. As for the rest, the big problem is most of it's in places that could be considered extremely problematic from a Western perspective.
Not that I'm a fan of nuclear, but if the rooftop generation is surplus to demand, it could be used to charge storage, which then could be onsold to business.This is Teslas take on the Peter Dutton Nuclear Fantasy proposal.
Tesla says Duttonâs nuclear plan will result in âsevereâ curtailment of household rooftop solar

Nuclear Policy & Planning Rooftop PV Solar
Tesla, the worldâs biggest electric car maker and leading supplier of utility scale and household batteries, has warned that Australian households face âsevere curtailmentâ of their rooftop solar PV systems under the federal Coalitionâs nuclear power plan.
The warning comes in Teslaâs late submission to the select committee on nuclear energy, where it says there is no room for both technologies to operate at the same time.
Tesla says there will be no room in the grid for more than 2 gigawatts of baseload. The federal Coalition announced on Friday that it wants to build 14 gigawatts of âalways onâ nuclear.
âNuclear is a complex technology to integrate into the power system, with constraints around ramping and load following (e.g. oscillating the pressurized reactor core) meaning it acts as a traditional baseload supply,â Tesla writes.
âAny large-scale build out of this type of inflexible baseload supply will therefore be impacted by minimum generation levels, resulting in either low-capacity factors for the nuclear plants and/or unit decommitment (bidding out of the market), or severe curtailment of cheaper rooftop solar and renewables.â

Hang on SP. What is currently happening is that rooftop solar power plus wind is effectively supplying the vast bulk of daytime energy requirements. That is why coal fired power stations are financially struggling.Not that I'm a fan of nuclear, but if the rooftop generation is surplus to demand, it could be used to charge storage, which then could be onsold to business.
Curtailment is only required when generation exceeds demand and there is no storage to soak up the excess generation.
Therfore it would make sense to just add more storage and onsell the power to business at a competitive price, that encourages more business investment.
The other obvious benefit for Tesla would be, if households are getting curtailed, a Tesla powerwall battery on the house would become a more attractive proposition.
The flip side of the argument is, if rooftop solar isn't being curtailed at peak generation times, it is therefore required and would indicate you don't have a lot of surplus generation.
Like I keep saying it is a complex issue.
Like I said I'm not a great fan of nuclear, however if you are shutting down rooftop solar that would indicate you haven't installed enough storage, at the end of the day if you can onsell electricity cheaply it will encourage business to grow, as per Twiggy and most other hydrogen plans being abandoned due to high energy costs.Hang on SP. What is currently happening is that rooftop solar power plus wind is effectively supplying the vast bulk of daytime energy requirements. That is why coal fired power stations are financially struggling.
The Coalition proposal would prioritise energy supply from nuclear power over energy supplied by millions of solar rooftops. Rooftop Solar power costs very little. in fact power companies pay 4.5c PkWH for it. Nuclear power on the other hand will cost far, far more than that.
The shutting down of roof top solar would be required to ensure millions of homes use nuclear powered electricity rather than what is being produced on site.
I'm on my second lot of solar panels and I love them, but I know there are a lot more times I import power, than export it.
I export during the day often, I import overnight always.
It isn't worth it yet, too costly and too long a payback time.Don't have batteries?
Did you check out that possibility?
That is the best idea and in fact should be quite close to technical/financial reality .It isn't worth it yet, too costly and too long a payback time.
I'm hoping on the vehicle to grid, vehicle to home situation to improve, then get the car and battery together.
To be clear, cutting power links is direct sabotage of the EUâs energy policy. It relies on Nordic electricity getting shuffled around central Europe to function.âNorway campaigns to cut energy links to Europe as power prices soar
âCountryâs energy minister describes â**** situationâ as domestic prices hit highest level since 2009
âNorwayâs two governing parties want to scrap an electricity interconnector to Denmark, with the junior coalition partner also calling for a renegotiation of power links to the UK and Germany, as sky-high prices trigger panic in the rich Nordic country. A lack of wind in Germany and the North Sea will push electricity prices in southern Norway to NKr13.16 ($1.18) per kilowatt hour on
Thursday afternoon, their highest level since 2009 and almost 20 times their level just last week. âItâs an absolutely **** situation,â said Norwayâs energy minister Terje Aasland.â
âIâm furious with the Germansâ, the governmentâs energy minister added. Just in case the Germans didnât know who the Swedish PM was referring to.âI realise that nobody is happy when I say that âif we hadnât shut down half of nuclear power, we wouldnât have these problemsâ. But itâs true and it needs to be said.â
