That is more water than ALL the dams in the world have water stored. Get real. There are these things called weather forecasts. Now from a 31 year period of sea sailing I have found that the forecasts are generally within 1 force on the beaufort scale out to about 7 days. That means the grid operators have a reasonable idea of what levels of power generation they will need and what they need in reserve so they can have coal power plant ready to meet short falls. The pump storage / NG / Hydro is available to meet the unexpected. Thats how it works in Europe. China is largely centrally planned so has certain advantages in that regard. We aren't talking about Texas here. Grid operators have the benefit of lots of historical info Demand throughout the day / week/month/ year Weather conditions that affect both demand and supply - wind speeds, sunlight, temperatures The commercial break times for Bejing Boulevard etc etc Quote Share this post Link to post Share on other sites
NickW + 2,714 NW April 7, 2022 (edited) This table is basically a demonstration of how windpower behaves over a whole Continent. Its Europe but I suspect China has a similar picture. The problem is many people can't scale from one turbine / one solar panel to 10,000's turbines distributed over a whole country / continent. China has 2 interlinked grids so would function in a similar fashion to Europes highly intergrated grid. Edited April 7, 2022 by NickW Quote Share this post Link to post Share on other sites
NickW + 2,714 NW April 7, 2022 For the same day this is Europe (inc non EU members) from all sources Solar is the most intermittent but coincides with part of the day with higher demand. In this situation Hydro, gas, coal and lignite throttle back to accommodate solar and provide peaking services in the morning and evening. Quote Share this post Link to post Share on other sites
NickW + 2,714 NW April 7, 2022 (edited) 16 hours ago, Jay McKinsey said: A doctrine of the fossil religion says that electrical generation from gas increases as wind and solar increase. The truth is that it doesn't. This chart shows the rapid growth of wind and solar while gas has remained flat: https://ember-climate.org/insights/research/global-electricity-review-2022/ Gas use in the UK dropped from a peak of around 100 bcm to 75 bcm in parallel with the rise of renewables. Some of that fall is down to improvements in efficiency but then nuclear and coal sourced output has fallen too. On the counter side our import through interconnectors has increased so the overall picture is similar to what you suggest.

Stop the exports until you get a fair price. Like Putin they care little for your children. heard they want more oil and gas but not the pipes...........

Or that small countries like Germany or Denmark subject to similar conditions. These places are NOT continents or even vaguely similar in size to continents. They are the size of modest (or even micro) US states, and the US itself isn't even 1/2 of it's own continent. A proper grid with regional interconnects takes care of temporary regional lulls in local areas like Germany or the UK. 1 2 Quote Share this post Link to post Share on other sites

Biden reckoned the US could supply 15bnm3 tops. Thats 1/10th of Russian imports. Depending on resolution of the Ukraine conflict, Ukraine could fill much of the gap from their 14 nuclear plants and about as much coal. Moldavia has surplus coal which was connected to the EU grid when Ukraine switched to the EU grid from the Russian grid in February this year. They will have surplus due to all the battle damage to loads.

Much of the coal plant is run in a peaking fashion due to CO2 targets. Switching them round to being baseload would increase coal fired output and reduce draw down on gas. As I type the UK is using 930MW out of 5.2 GW of its coal capacity. Ireland 210MW of 1.2GW Germany 19.5GW out of 39GW and so on. Quote Share this post Link to post Share on other sites

I had no idea there were that many plants still available - looks like they CAN substitute coal for gas to a great degree presuming they can get enough coal.

Boat + 1,325 RG April 12, 2022 Iowa’s use of renewable energy sources is the highest in the country, according to an American Clean Power Association report released Monday. About 57.6 percent of electricity generated in Iowa came from renewable sources, according to the report. No other state had more than half of its electricity come from renewable sources. Kansas was the next highest state with 43.4 percent, followed by Oklahoma with 35.5 percent, South Dakota with 32.9 percent and North Dakota with 30.8 percent. Look, no deaths at over 50%.

They can get it from the US, South Africa, Brazil, and in a pinch Australia which is in a tiff right now with China. Germany is decommissioning nuclear plants not coal. Their coal plants also have Natural gas and #6 oil burners as well and had been burning NG. Britain can burn #6 instead of coal which is what happened back in 1984 during the coal strike. Low load in spring is good time to do a turnaround to optimize for coal. Quote Share this post Link to post Share on other sites
