    That's a weird reaction.
    If anything, not evolving to the changing conditions would be more unexpected.

    This is exactly what Darwin wrote about so many years ago.
    A few mm larger here, and few mm longer there, it all counts. We probably won't see it, but in say 100 years that generation will have the data to confirm that the average beak, or bill or feather or whatever ... has got larger since more accurate records were being catalogued.
    Cheers,

    Watched a interesting plan to release water from some dams to allow the massive power at the lake med - hoover dam to keep the lights on for three US states



    The dams mentioned in the very annoying computer voice in the video below are in the above this link. Flaming Gorge Water Database Flaming Gorge, Aspinall dam and Navajo dam. Aspinall isn't in the link It seem to be three "Crystal Dam
    Blue Mesa Dam
    Morrow Point Dam
    "

    A quick look at each of the dams was a wow, Hoover power is "about 4 billion kilowatt-hours of hydroelectric power each year for use in Nevada, Arizona, and California - enough to serve 1.3 million people"

    That seem to be a lot of power to replace if 'dead pool' the term they are using if the water is below the outlet pipes of the Hydro station(s)

    If your interested have a look at Lake Navajo. It they are counting on it to save their power and water needs I suspect they are in real trouble and making more trouble for locals at several places listed.

    Hope they get lot of snow and rain falls. Its been a dry 20 years for them.

    4 billion KWH = 4 million MWH = 4,000 GWH.

    For a year..........divide by (365 x 24 = 8,760) = 0.457 GW / yr.

    The **** ant Yambuk windfarm puts out 90 GW / yr.

    Am I missing something here? Dud maths? (very happy to be corrected).

    thank god I am not a Sparky. 2-3 US states I can count to from the reports. PS Yambuk is clearly cool

    Well.............. Yambuk is small and relatively old, but it does have published annual outputs which does match its 30 odd % capacity factor. None of that info is easy to access.

    Kiata is newer and has a capacity factor of around 47%, newer farms using bigger turbines like Berrybank would be higher again.

    I suspect the quoted Hoover figure is wrong.

    Yes. You are messing up rate and quantity. First line is correct, 4,000GWH

    And, as stated at the beginning that is the quantity of energy produced per year - you don't need to divide it by anything. And it is large compared to the Yambuk wind farm, assuming that you meant to quote it as 90GWH/year.

    To reiterate:-

    Watts, Kilowatts, Megawatts and Gigawatts are a measure of the rate at which energy is generated, used, transported etc. Adding "per hour, year etc" is a meaningless quantity

    Watt-hours, Kilowatt-hours, Megawatt-hours are measures of the quantity of energy generated, used, transported and is the number of Watts multiplied by the number of hours etc. Kwh/hour = kilowatt

    General Sherman - Hands to Action stations - Not kidding

    Firefighters are wrapping fire-resistant blankets around ancient trees as blazes tear through California's world-famous Sequoia National Park.


    Officials fear the fire could reach the Giant Forest, a grove of some of the world's biggest trees, within hours.


    The forest hosts some 2,000 sequoias, including the 275ft (83m) General Sherman, the biggest tree by volume on Earth and about 2,500 years old.


    The Colony and Paradise fires have been growing for a week.


    More than 350 firefighters, along with helicopters and water-dropping planes, have been mobilised to battle the blazes.


    They have wrapped several trees, including the General Sherman, with aluminium foil to protect them.
