southbeach1500 saidAbout 80% of the power stations likely to be in use in 2020 are either already built or under construction, the IEA found. Most of these are fossil fuel power stations unlikely to be taken out of service early, so they will continue to pour out carbon – possibly into the mid-century. The emissions from these stations amount to about 11.2Gt, out of a total of 13.7Gt from the electricity sector. These "locked-in" emissions mean savings must be found elsewhere.
The 13.7 Gt is almost half the carbon output.
Not a good way to go at all.
The main culprit for the wind slowdown is spring weather that followed a winter with heavy snow in the mountains feeding the Columbia River basin. The spring surge is expected to be the largest since 1997.
When water levels are this high, the agency said, it has no choice but to use the water to generate electricity in hydroelectric dams. Laws protecting endangered species prevent it from sending all the excess water through spillways and around the dams. That beats up salmon and steelhead. It also creates so much nitrogen gas bubbling in the water that the fish get the equivalent of the bends.
Grid operators say they have run out of capability to sell the surplus electricity, store the water or shut down gas, oil, and nuclear plants – leaving wind farms the unfortunate victim.
