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.
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.Quote:

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 coolQuote:

I suspect the quoted Hoover figure is wrong.

Dam you google [thumbsupbig]Quote:

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.[wink11][wink11][wink11]

Four significant giant sequoia trees were not harmed by a wildfire that reached the edge of Giant Forest in California’s Sequoia National Park, authorities said Link
That's great to hear. I want to see those trees If I can.
A little further south in Brazil things might be a bit dry and dark? Oddly Daylight savings is a issue there as well.
"Brazil’s reservoirs are dwindling. In a country where almost two-thirds of power comes from hydroelectric generation, low rainfall has serious consequences. The situation is so bad, Bolsonaro asked Brazilians on September 23 to stop using elevators when possible and to take “much healthier” cold showers."
Oddly I see an Aussie company about to restart refining bauxite there."Alcoa’s restart of its idled Brazilian capacity and Russian producer Rusal’s reactivation of its long-delayed Taishet smelter project."
Cannot see how that will work if the power is limited ???? Off Topic I Wonder if Portland (VIC) might recover If prices are jumping as suggested.
"BRASILIA, Sept 1 (Reuters) - Brazilian Vice President Hamilton Mourao said on Wednesday a severe drought could lead to energy rationing in Brazil, contradicting other officials who have said that such a step would not be necessary.Brazil, one of the world's agricultural superpowers, is suffering from one of its worst droughts in a century. The lack of rainfall has emptied hydroelectric reservoirs, fanned inflation and hurt farmers. The government has given incentives to use less energy but says rationing is not expected."
Some on is telling fibbs?
"Brazil's Mines and Energy Minister Bento Albuquerque on Tuesday said the country's energy crisis was worse than previously thought. In a televised national address, Albuquerque said Brazil had lost hydropower output equal to the energy consumed by the city of Rio de Janeiro, Brazil's second largest, in five months." Link
Wouldn't be related to rainforest clearing by any chance? [biggrin]Quote:
