    Another article on European energy prices.


    According to the Wall Street Journal yesterday, due to a rare lack of North Sea wind, already high European energy prices are climbing higher.
    “Gas and coal-fired electricity plants were called in to make up the shortfall from wind.
    Natural-gas prices, already boosted by the pandemic recovery and a lack of fuel in storage caverns and tanks, hit all-time highs. Thermal coal, long shunned for its carbon emissions, has emerged from a long price slump as utilities are forced to turn on backup power sources.”
    Prices in the U.K have jumped. The inset graph shows average U.S. wholesale electricity prices from the EIA for 2021 in $/MWh but scaled to be roughly equivalent to the EUROs in the larger graph.
    “Two U.K. energy retailers—PFP Energy and MoneyPlus Energy—went out of business when electricity prices spiked this month. The companies, with a combined 94,000 gas and power customers, didn’t return requests for comment.
    Winners include U.S. and Russian companies exporting gas to Europe, as well as renewable-power suppliers producing electricity with near-zero operating costs. Shares of Cheniere Energy Inc., a major U.S. exporter of liquefied natural gas, have risen 47% this year.”

    Funny how quiet the "75%s" are

    Yep, when the wind doesn't blow or the sun isn't shining, there are limited things other than burning fossil fuels at the moment unfortunately.

    On a windy, sunny day 75% and more is achievable in lots of places, but that doesn't mean 75% all the time. Not sure of the exact numbers but overall would be quite low I think.

    With Yallourn now scheduled for closing that will only leave Loy Yang here in Vic to do the heavy lifting - along with dozens of small gas plants and the wind/solar - I think we're heading for a large problem in the next 10 years.

    I read Australia averaged 30% renewable electricity nationwide last year, so there's still a way to go. The states have good policies, but not much is happening federally.

    According to this Government website (Geoscience Australia) - Coal and gas make up 91% of all electrical generation in Australia. Overview | Geoscience Australia

    Now there's no date on this so happy to be corrected by your data, but this is all I managed to find.


    • Australia’s primary energy consumption is dominated by coal (around 40 per cent), oil (34 per cent) and gas (22 per cent). Coal accounts for about 75 per cent of Australia’s electricity generation, followed by gas (16 per cent), hydro (5 per cent) and wind around (2 per cent)."

    Our lovely new Cooling fan array up the road was effectively burning energy last Saturday.
    All their cooling packs were operational, and now a single unit producing energy.

    Why? Almost zero wind… which in a twisted irony is quite common here between April and October - when solar output is lower.

    And the whole, once pristine landscape now looks like a giants birthday cake - it’s disgusting.

    Agree…..it’s destroying the views and landscape

    I drive through Warwick every second week and the solar farm is an eyesore and has consumed prime agriculture land. I wonder how many houses the solar farm actually provide guaranteed power 24/7 for 12 months.

    Personally I cannot see the world or even australia getting anywhere near close to having a sustainable renewable energy solution for the masses………

    the world is just too power hungry…..

    there is either a new solution that hasn’t been made public to it’s going to take a new invention……otherwise the world is toast

    Huge potential, if we get more determined.

    The world is hungry for solar panels. Why did we stop making them?

    OK, I guess all know I am sceptical about the future of solar but there is obviously some big money behind it.
    I have attached a photo of the Breakers Club ( golf, Bowls, RSL) at Wamberal on the Central Coast of NSW.
    There has just now been built 4 frames over the car park and 3 are now apparently commissioned.
    Each frame has 11x10 solar panels so when the 4 are finished it will be 440panels. this is in addition to about 200 on the roof of the club.

    IMG_1966 (002).jpg

    That is a ****load of power and it also provides shade in the car Park so a win win.
    I do not know the financial arrangements but I guess I assume the club does not own them. I have asked my wife who knows the CEO to find out.
    Regards PhilipA

    While on a long dive Visit to Northern NSW South QLD pre covid. I parked in a shopping centre which has the same Solar panel roof over a lot of the car parking. Highly sort after parking spots mid January !

    Great idea as I assume pay back sub 3 years when using all that power to cool the buildings mid summer.
    Does the the beer fridge at the golf club would now provide green beer Phillip?

    Thought it was like all manufacturing here and it was too expensive.
