Ethene, is a double bond monomer of 2C. CnH2n or C2H4. - 'c = c' - Polyethene, is a polymer formed by joint multi unit monomers of ethene. For ethene to be elongated, the double bond would be broken and used to form a bond with adjacent carbon. (C2H4)n C ( - 'c,- 'c, -) c........ When melted into liquid, it would be hydrocarbon. How to control its length and the type of gas formed when burnt, there would certainly be a way. Chemical processes of these few are interchangeable, if not mistaken. Ethylene and polyethylene are already hydrocarbons. They are literally made of carbon and hydrogen. But yes, you can make any desired alkane from ethylene. Start with sugar from corn, grains, or fruit and ferment it into ethanol. Dehydration of ethanol yields ethylene, which when polymerized yields long alkane chains. You can then crack the polyethylene plastic into shorter chain hydrocarbons (liquid fuels). The idea that we absolutely need fossil fuels is wrong. It is just much, much cheaper to dig the stuff out of the ground than make the ingredients chemically. Quote Share this post Link to post Share on other sites

It is destroying Russian aggression and their future power plays. It has also warned off China from attacking Taiwan, at least for now. China is also in a desperate economic crisis for several reasons: Europe followed America's lead in supporting Ukrainian freedom and independence. Europe freed itself from dependence on Russian oil and gas. NATO and others imposed severe and growing sanctions on the Russian economy. Europe, and all Western nations and their allies became unified against not only the Russian Bear, but also the Chinese dragon. Their past reliance on massive housing construction that is now abandoned and useless. The massive debt held by their citizens, banks, businesses, and government at all levels. ( Worse even, than that of Americas.) The flight of international manufacturing to other countries, which is due to the lack of faith in Xi's dictatorial administration and grandiose plans for Chinese hegemony. The aging of the Chinese population which places a burden on the younger generations, who will need to support their elders. Competitive nations like India and other nations have a much younger population distribution. China needs to rid itself of the Chinese Communist Party and Xi to become accepted by the world as it was during China's rise. Communism and dictatorship has been shown to be a path to failure for any nation which lives under its policies. Unfortunately, America is becoming more like Canada and Europe politically. If this is not turned around 180 degrees, we will become a democrat socialist nation like the ones in Europe. Our economy will falter, along with our traditional American values. Anyone with eyes to see, is watching it happening all around America. Biden is a leader in that movement along with his whole administration and all the government employee unions, teachers unions, USPS, major media, wealthy foundations run by the grandchildren of great business leaders, etc. etc. You do realize that unions gave you and I this thing called "the weekend", no?? 1 Quote Share this post Link to post Share on other sites

Nina RaemontWriter A recent graduate of the University of Minnesota, Nina started at CNET writing breaking news stories before shifting to covering Security Security and other government benefit programs. In her spare time, she's in her kitchen, trying a new baking recipe. See full bio Nina Raemont June 9, 2023 11:53 a.m. PT 2 min read James Martin/CNET Solar energy installations surged in the first few months of this year, thanks in part to supply chain challenges easing. The US solar industry installed 6.1 gigawatts of solar capacity in the first quarter of 2023. That's enough power for more than 4 million homes. The data comes from an industry report released Thursday by the Solar Energy Industries Association and research firm Wood Mackenzie. The record quarter was driven in part by delayed solar projects proceeding once again as supply chain problems have softened, said the SEIA. Renewable energy incentives in the Biden administration's Inflation Reduction Act also helped spur demand. Installation in the residential segment increased 30% compared with this time last year, to 1.6 gigawatts. The residential market is expected to add 36 gigawatts of solar over the next five years, according to the report. In total, the SEIA says there's enough solar energy currently installed in the US to power 26 million households. Many people look to rooftop solar as a greener and (in the long run) cheaper way to fuel their homes, CNET's Katie Collins explains. It can also improve a home's value and energy independence. But solar doesn't work for all homeowners, including those who don't want to spend money on the upfront costs or those without ideal conditions for the panels. If you're considering solar panels on your home, CNET breaks down installations, tax credits, batteries and everything else you need to know to get started. The commercial market segment also experienced a record first quarter, installing 391 megawatts, according to the report. Florida had the most solar installations in the quarter, across commercial, residential and other sectors, with 1.46 gigawatts. 1 Quote Share this post Link to post Share on other sites
Ron Wagner + 698 June 12, 2023 On 4/17/2023 at 9:19 PM, markslawson said: Posters on this site have been denying the reality of an apparent collapse in investment in green energy projects. Whenever this is mentioned they quote annual figures and total investment in teh sector in much the same manner as characters in movies hold up a Christian Cross to deter vampires. Sure some of the past annual growth looks impressive, if you don’t try to adjust the quoted plated capacity new wind and solar projects with the likely capacity factor. But in 2022 and this year green energy investments seem to have hit a wall, particularly in the last quarter of 2022 and the first quarter of this year. This is from the wind lobby group WindEurope, in February. The European Commission wants wind to be 43% of EU electricity consumption by 2030. But right now new investments and wind turbine orders are falling. 2022 saw only 13 GW of new wind farm investments announced. Not a single offshore wind farm reached final investment decision. Wind turbine orders fell by 47% on 2021 to 11 GW. There are two reasons why wind investments are falling. First is the high inflation in input prices which is insufficiently reflected in developers’ revenues. Higher commodity and other input costs have added 25-40% to the price of turbines, but wind farm developers are often stuck with a revenue base that is not indexed in line with this. Governments must fully index their auction prices and tariffs. Second, a series of unhelpful interventions in electricity markets by different national Governments have badly undermined investor confidence. Remember the 13 GW figure actually works out to an average output of 4.3 GW (average output for a windfarm is typically one third of plated capacity) and is for all of Europe. In other words, effectively nothing. In Australia, the Clean Energy Council has been producing releases pointing to impressive numbers for investment, with one story claiming that investment rose a full order of magnitude in the December 2022 quarter. Really? Anyway a check of commissioned projects (a more reliable indicator than proposals or finance approvals) listed on the site shows that just 17 were commissioned in 2022, representing 1,248 Megawatts (MW) of installed capacity, as opposed to 48 completed in covid-stricken 2021 adding up to 4,589 MW, and 3,205 MW worth of projects in 2020. In 2023 (meaning the March quarter of 2023) the number of projects was two, albeit seemingly large ones, adding up to 442 MWs. Why has this happened? WindEurope cited above gives part of the answer. Also, elsewhere the generous subsidies/tax breaks offered by the US Inflation Reduction Act is cited as siphoning off European investment to the US (I have not looked at the US figures but I'm not hopeful they will be much better). In addition, and probably mostly importantly of all, markets did not do well generally in 2022. A count of Initial Public Offerings (for Australia) on the securities exchange by professional services firm HLB Mann Judd shows that the number of new IPOs fell by 48 per cent in 2022, and total funds raised collapsed 91 per cent. Investment in renewables may pick up later, but in Australia the present hiatus could result in disaster in a few years, with activists still intent on throwing away the fossil fuel backup. As matters stand there may be nothing to replace those coal plants. Where can I buy a generator?

Their foolish plan of buying from Russia led into them being blackmailed with high prices and claims of Russia not having enough gas supply. Apparently you do not see the true causes of things. No, no its not! I live here Ron I'm more aware of the issues Britain has on energy supply and what has caused the spike in costs is a direct correlation to Russian gas and the war in Ukraine. You say the fundamental reason is our reliance on Russian gas, no no and no again. The UK used to import 3% of Russian gas, yep thats all, the vast majority was from Norway. The problem with that is due to the Ukraine war it sent NG prices skyrocketing including Norwegian NG like any other supplier. Nobody was being blackmailed there was an imbargo on Russian NG so there was a massive shortage hence the massive price increases. Do you now get it? The below is taken from this, please look at the graph https://www.statista.com/statistics/1174560/average-monthly-gas-prices-uk/ "The average gas price in Great Britain in February 2023 was 134.54 British pence per therm. This was a notable decrease compared to the previous months with prices still impacted by developments in the Russia-Ukraine war and global natural gas demand." You are trying to misdirect and making statements when you havent done your fact finding, as EWO was with his post that is 2 years old that the wind isnt blowing. Why do you think the costs are now falling very quickly allied with the NG price? Surely if you're correct then prices should remain astronomical as the renewables havent gone away and they havent suddenly gotten any cheaper. If that isnt correct then please explain in detail why its all down to renewables. To answer your point on developing our own FF then we have, 50% of the UK's NG is from domestic production. The point is there is no further economic way of drilling new fields, its far cheaper to buy NG from Norway which is the dominant exporter to the UK. Hope that now clears that up!

Told you we wouldnt agree Mark lol The below extract from this article from July last year https://www.theguardian.com/environment/2022/jul/08/price-offshore-wind-power-falls-cheapest-ever-level-uk Offshore windfarm operators will sell power for as little as £37.35 per megawatt hour, 5.8% below the lowest bid in the most recent auction in 2019. The “contracts for difference” guarantee wind-power companies fixed prices to sell electricity for the following 15 years. If the market price falls below the contract price, the government subsidises the difference. If the market is higher, the companies pay money back to the government. The UK last year paid on average £172.56/MWh mainly due to the exhorbitant gas prices. I think your numbers are wildly exaggerated regarding costs per MWh and the maintenance of wind farms. Maybe you have looked at very old data?? The maintenance of a coal station does not just centre around the gas and steam turbines, you have boilers and the associated pipework which is actually the most expensive part of the plant, water jackets and huge pipe hangers, steam chests, reheaters, cooling systems, generators etc etc. There are far more things on a CCGT plant to maintain than on a wind farm and that comes at a price. See link below https://www.tycoonstory.com/an-overview-of-components-and-maintenance-of-combined-cycle-power-plants/ Anyway the UK generated on average 350MWh per day or 1.2% of the UK's powergen's need. There is no way we are going back to coal, in fact the infrastructure doesnt exist anymore to do it even if we wanted to. Hope that clears that up for you. 1 Quote Share this post Link to post Share on other sites
