NG is the predominant form of energy used in UK powergen, however renewables are catching up fast especially wind power, coupled with many large scale battery storage back ups to maintain reliability. Renewables were 25.5%, with wind 20.1% of that total. https://grid.iamkate.com/ https://www.nationalworld.com/lifestyle/money/where-does-the-uk-get-gas-from-how-much-is-imported-from-russia-current-supply-and-if-theres-a-gas-shortage-3391351 The UK is extremely fortunate geographically to have the gulf stream blowing along its coastline almost all of the time. Once the infrastructure is built it is low cost. Wind power as an energy source is free NG isnt. Moral of the story is the UK's wind power currently creates 10's of thousands of jobs and has saved many historical oil & gas businesses as they diversify their skills into renewables. The US is set to have a lot more wind turbines on and offshore in the next few years so get used to them. Solar is so cheap now against retail costs its worth using surpluses to heat hot water to displace gas use. I have 1.46KW of PV (self install) and a diverter than sends surpluses to the immersion. Late summer I'm putting in another 2.4KW. Its a simple form of storage and frees up gas 1 1 Quote Share this post Link to post Share on other sites
NickW + 2,714 NW March 21, 2022 probably a better question Ron is where will we be over the next 10 years. Offshore wind is now opening up globally whereas it was just limited to north west Europe. I see Brazil has recently opened up seabed areas that can support 17 GW of generation. Europe still has a massive pipeline of major projects, particularly the UK South Korea, USA even Australia is moving ion this area. 1 Quote Share this post Link to post Share on other sites

Robert Ziegler + 121 RZ March 22, 2022 How far we have gotten..... That is simple: To the end! Why? Because we exit the most unique decade in the history of the industrialized world, where de-facto negative "cost" of capital (thanks, Fed!) together with energy and metal prices below "development/replacement cost" led to the mother of all malinvestments: Wind and Solar. These Windmills and magic black panels are enormous resource hogs, and it is not even remotely possible to replace them by using the energy "produced" by them in use, and even less possible to use that energy to get new metal/mineral resources to replace them when worn out. These ruins will scatter our landscapes for a few more decades, until smart scrap dealers have them all dismantled and sold. It is the second end of that era (OK, some solar will remain as a niche for remote places). 2 2 2 Quote Share this post Link to post Share on other sites

IF there is a 'calm' season it tends to be summer nights. Averages is not reality and why the topic of a winter HIGH system is relevant across NA, EU, ASIA. There is no wind/solar during said system after it sets in. It also ushers in the coldest temperatures and highest heating load requirements. Can last weeks. Look no further than the winter high system which knocked out the Texas Grid which was on the edge of said winter high at the time. Pull up data from wind farm in area from last year and then compare it to a wind farm in Iowa or Minnesota. None of them were producing much if any power for weeks. Yes, summer is worse, but one has consistent solar during summer and why it is not a big problem, unless of course you put up massive numbers of wind turbines in the vain hope that is all you need. One needs several multiples of capacity is the big takeaway and you still need massive stored power backup good for a week or two in ideal conditions. And no, the windiest season is not winter, rather fall/spring by a wide margin across the great plains. Open any wind rose. Winter is average. Has big storms(have to shut down wind turbines) which even out the large lulls. Edited March 28, 2022 by footeab@yahoo.com Quote Share this post Link to post Share on other sites

I had a big derrick go up within a couple of hundred yards of my house! I remember the trucks driving around with their sonar before the drilling. Of course we had no mineral rights. We had a small flare tower within a few miles also. They had to give us free cleanups one time due to spots of tar on a lot of cars around the area. We have "donkeys' near me in central Illinois, and some minor production.

If it is not there is biogas if there are people. Someone gave an alternative perspective as feedback over issue on energy crisis somewhere. Share it here (edited) for your reference. Hope these info are useful to assure everyone that instead of out-competing one over another, they could most likely co-exist…. First of all, the general perspective over the average percentage of each energy sector is probably as below: a) hydroelectricity (30% to 90%, median point of the world 50% to 70%), countries where the main source of fresh water is probably cactus might not have been counted in. b) fossil fuel e.g. coal, petroleum and its derivatives, petroleum gas, etc (10% to 30%) c) Others e.g. renewable solar, wind, non renewable nuclear etc (10% to 20% or less) Second, the insecurity considered is probably based on the news that fossil fuel would be running out soon and it is popularly believed to be the major culprit of climate change. From the percentage provided above, it might be obvious that countries with water catchment areas that bestow hydropower should keep their forest, water and power. Countries without, should start to think about ways to create their own water catchment areas in their own countries. For your information, most countries in the world might have 0% to less than 30% of forest remaining. The later action will not only ease off the uneasy feeling, but will drastically improve issues related to climate and water shortage drastically. Solar and wind are good choices considering they are abundant and free. However, seasonal change, climate change, topological change would affect the effectiveness of these energy mentioned. For examples, no sun due to geological limitation, no wind due to climate change, too much development created too much dust that clouds the solar panels and still the wind often etc. The efficiency in some temperate countries is as low as 10% to 20%. Unless these perspectives are widely acknowledged, the push to make them mainstream could create more unsettling issues later. 1 Quote Share this post Link to post Share on other sites
