 Okay, so we have a mix of electricity generation capacity, that is primarily fossil fuels, right? So the pie chart on the left is our capacity to generate electricity. And so it's about 70%, you know, coal and natural gas. So these are our power plants. But if you look at the actual electricity that's generated, our coal plants and our nuclear plants are used a lot more intensively than, say, our natural gas plants, or especially our petroleum-fired plants. We have some oil-fired capacity in the U.S., but it almost never gets used. And there's a good chance that a lot of it will be retired within the next 15 years or so, because of environmental reasons primarily. So, but still about, you know, about 70% of the electricity that's generated comes from fossil fuels, right, primarily coal and natural gas. Another 20% is nuclear. And then there's, you know, things like petroleum, you know, hydro-bio-mask, and so on and all of these things. Those account for a much smaller percentage of our electricity generation. Question? Yes? So you're going to handle on, so obviously the electric generation capacity is not entirely used, and it gives us an idea of the fraction of which each particular generation source makes up what's generated. Do you have an idea of what, like, the capacity factors of the overall grid and how much of the capacity we're actually using overall? So the annual capacity factor is, the annual capacity factor is probably somewhere close to two-thirds. Oh, yeah. Well, so, but that's average, right? Right. I mean, and, yeah. But what's really driving that is that there's a big chunk of capacity that we only use when electricity demand is really high. Right? And so we have a lot of what we call peaking plants. Right? So in PJM, for example, you know, 15% of all of the generation capacity is used in less than 100 hours a year. Right? And so the amount of capacity that we have to have on hand for to accommodate peak electricity demand during the summertime is fairly substantial. So within fuel types, you know, coal plants and nuclear plants tend to have higher capacity factors. Natural gas plants tend to have pretty low capacity factors, because a lot of those are used for peaking. Okay. What is the hydroelectric drop? Because I know coal and nuclear are pretty much static, so people can't vary, but wouldn't hydroelectric be the same? Not necessarily for two reasons. One is that there's a good amount of the hydro generation in the Pacific Northwest is what we call the run of river, which means that there's no storage. So there is very limited ability to control how much water passes through dams and therefore how much electricity is generated. The second reason is that a lot of hydrocapacity, where there is storage, is used for something called load following. Okay? And that's kind of like peaking today. So it's not producing electricity at a constant rate all the time, but rather the electricity that is produced goes up and down in response to fluctuations in demand. So that's why. So are not hydro plants pumped hydro, or do they just not run and let it fill up slowly? So there are a lot of pumped hydro plants. The biggest hydro dams are generally not pumped storage because you need a really big pump or something like that. So the biggest hydro dams, most of which are located in the Pacific Northwest, either have a sort of marginal amount of storage behind them or what we call a run of river. If you go up to Canada on the other hand, their big hydro dams have years worth of water stored behind them. And so there's a big difference in the way that Canada and the U.S. offer big hydro dams. And just having a dam doesn't imply storage. Right. You have to pump it the other way. You would either have to pump it the other way or you have to have a big reservoir behind the dam. Um...
