Monday Feb 25 in the morning. Not a sceenshot so it will change. At 9am (Sydney time) the wind was delivering less than one GW, 13% of plated capacity and 3.5% of demand (25GW). I check daily at 9am and 6.30pm and I don’t recall any time in the last week when wind topped 10% of plated capacity. Mostly it was under 5%.
Don’t get over-excited about South Australia despite the beatup of their RE industry in a colour supplement to The Weekend Australian. They can produce about half of the Australian windpower at present but last night it was not enough and they were taking power from Queensland and Tasmania via NSW and Victoria.
Fun times ahead.
6.30 Dinner time update. The sun and the wind are now providing 3GW that is 12% of demand. The sun will soon set and it is all up to the wind that is blowing almost 1GW(4% of demand.) So we will need about 25 x windmills. What a good thing RE is so cheap or it might have to be subsidised. But wait…
Beware of the green energy transition. Check out the German experience!
Approaching noon on a late summer Sunday morning the sun and wind are contributing 5 GW to the total consumption of 22 GW. That is less than a quarter. On weekdays the demand rises over 25 and of course in high summer it gets well over 30.
The wind is delivering 1GW. That is 4.5% of the demand and 15% of the plated capacity.
Someone work out the cost of increasing the capacity of wind and sun power to meet this level of demand and also the demand at 30GW or so. It will be easier when the aluminium and steel industries close. Just as well we have given up on car-making.
Because RE zealots crowed about Germany’s ‘inevitable transition’ to wind and solar from the outset, it’s no surprise that its disastrous conclusion is attracting attention, much like a freeway pileup.
Germany’s so-called Energiewende (energy transition) has turned into a power pricing and supply calamity. Which was as perfectly predictable as it was perfectly avoidable.
Its the choke point, stupid!
Unfortunately, most of the time the actual amount of electricity produced is only a fraction of the installed capacity. Worse, on “bad days” it can fall to nearly zero. In 2016 for example there were 52 nights with essentially no wind blowing in the country. No Sun, no wind. Even taking “better days” into account, the average electricity output of wind and solar energy installations in Germany amounts to only about 17% of the installed capacity.
Why have trees when you can have windmills?
