#clickbait #video on #solar #energy claiming #China is “no longer approving” coal power plants. Talking-head filler interspersed with web-page screenshots and misleading stock footage (e.g. of concentrated solar power to illustrate a #photovoltaic plant). Claims #Australia will build an even larger solar farm than China’s at, implicitly, Crescent Dunes within the next 5 years. Claims 210 gigawatts of renewables added so far in 02024 (as of November 19, according to a Renew Energy reneweconomy.com story) of which 161GW was grid-scale solar, 39.1GW of #wind power, 7.97GW of hydroelectric, and 1.37GW of biomass, and that coal power plant approvals have fallen 80% according to Greenpeace, or that last year approvals for new coal power plants fell by 92%, or that over the first 9 months of 02024, an increase of 21% over last year; “86% of all power added to the Chinese grid was renewable energy” (unclear if peak or average). Claims that the average [residential?] solar [power] system being installed in #Australia now is 10 kilowatts. Claims that 70% of coal power plants are running at a loss, and that coal power plants need to hit a 70% capacity factor [in what country or countries?] to be profitable. Claims that China shuts down its coal power plants during the day, which seems unlikely to me. Claims that at the end of the third quarter this year, “China’s renewable energy generating capacity had reached 1.73 terawatts, a year-on-year increase of 25%.” Confusedly claims that the difference between the 25% increase in total renewable energy capacity and the 21% increase in the pace of renewable energy installations results from installing batteries and therefore improving the capacity factor of solar, but of course there is not particular reason why these figures ought to be close (it just indicates that growth is nearly exponential) and both numbers are nameplate capacities into which the batteries don’t figure at all. Claims China has installed more solar than the rest of the world combined this year, which is of course true. Claims Tesla’s installation of [utility-scale?] batteries this year is double that of last year, and that they have a two-year backlog of orders.
right-wing #news #video claiming #UK export controls to Russia over the #Ukraine war have been ineffective because the same exported goods are just flowing in through neighboring countries in the Caucasus and central Asia such as Georgia and “what we would see as the Stans”, while UK luxury car exports to those same countries have “skyrocketed”, “particularly #Azerbaijan”. #Clickbait headline promises information on an announcement of new sanctions, but no such information is available. Fuck you, Sky News.
#news #video on the December 24 elimination of the 7.5% impuesto PAIS tax in #Argentina and the immediate elimination of its withholding (presumably for imports after that date), following its reduction from 17.5% in September. This will also lower the dólar tarjeta exchange rate for credit-card #forex exchange. The bienes personales tax is also being lowered (how much?) and its non-taxable minimum increased (how much?) and the real-estate transaction tax (impuesto a transacción de inmuebles) also eliminated. But the impuesto a exportaciones still survives!
#news #video saying last night at least 17 Russian drones hit #Ukraine out of a total of 188, of which 76 were shot down and 95 lost from radar tracking for unknown reasons. Also 4 Iskander-M ballistic missiles were fired, but apparently no more #Oreshnik missiles. Odessa recently had a multi-day power and drinking-water outage, and attack-induced blackouts are common across Ukraine.
#news on the #EU imposing 35.3% punitive import #tariffs on electric vehicle (EV) imports from #China earlier this year on top of the 10% standard import duty (and I suppose VAT). China ended its joint-venture rule in 02022, maybe due to #Tesla, while the EU is maybe enacting it as a way to, in effect, drop the tariffs. This #video (by #EV-Insight) is pure irrelevant stock-footage filler. #politics #EVs
#news #video on a 1-gigawatt #solar #photovoltaic offshore farm in Shandong, #China, consisting of 2934 solar platforms built on steel trusses, connected with 66kV transmission. Predicted production would be 1.78 billion kWh/year, which is 203MW, a 20.3% capacity factor, which I think is roughly double the Chinese average. I wasn’t expecting this for 20 years. #energy
the Renew Economy article on #China’s 210GW of new renewable #energy generation capacity installed in the first three quarters of 02024, “an increase of 21 per cent on this period in 2023 and accounting for 86 per cent of all new power capacity added in the year”, according to the National Energy Administration (nea.gov.cn). “(...) new capacity installed through the first nine months was led by #solar, which added 161GW of new capacity added.
A further 39.12GW worth of new wind power, 7.97GW of new hydropower, and 1.37GW of new biomass power rounds out the new capacity added so far in 2024.
At the end of the first three quarters, then, China’s renewable energy generating capacity had reached 1.73TW, a year-on-year increase of 25 per cent.” Perhaps more important still: “In terms of actual generation, the NEA figures showed that China’s renewable power generation reached 2.51 trillion kWh, an increase of 20.9 per cent over the same period in 2023, and equivalent to around 35.5 pct of total Chinese power generation through the first nine months of 2024.” Presumably that’s only counting electric power in the denominator; that would be 382GW on a total of 1.08TW, and I’m pretty sure China overall uses more than 1.08TW of energy. Like, probably more like 2–3TW. #photovoltaic
press release from #China’s National Energy Administration (国家能源局); auto-translation: "In the first nine months, newly installed renewable #energy power generation capacity exceeded 200 million kilowatts
Release time: 2024-11-15 Source: Economic Daily
Data released by the National Energy Administration on the 31st showed that in the first nine months, the country’s newly installed renewable energy power generation capacity was 210 million kilowatts, a year-on-year increase of 21%, accounting for 86% of the newly installed electricity capacity. Among them, hydropower has added 7.97 million kilowatts, wind power has added 39.12 million kilowatts, #solar power has added 161 million kilowatts, and biomass power has added 1.37 million kilowatts. As of the end of September this year, the country’s installed renewable energy capacity reached 1.73 billion kilowatts, a year-on-year increase of 25%.
At the same time, in the first nine months, the country’s renewable energy power generation reached 2.51 trillion kilowatt hours, a year-on-year increase of 20.9%, accounting for approximately 35.5% of all power generation. (Reporter 王轶辰)” Here “power generation” is a translation of “发电量”, which is specifically electrical power generation. 2.51 trillion kilowatt hours is 9.04 exajoules, which works out to 382GW over 9 months, which is an overall capacity factor of 22.1%, a weighted average across presumably solar, hydro, wind, and biomass. #photovoltaic
Press release from #China’s National #Energy Administration (国家能源局), saying, “the installed capacity of #solar power generation is approximately 790 million kilowatts, a year-on-year increase of 48.0%; the installed #wind power capacity is approximately 490 million kilowatts, a year-on-year increase of 20.3%.” (“太阳能发电装机容量约7.9亿千瓦，同比增长48.0%；风电装机容量约4.9亿千瓦，同比增长20.3%。”) They also increased thermal power capacity (火电, which apparently specifically means fossil fuels and excludes an almost insignificant #nuclear) by 3.8% to 142597 tens of thousands of kilowatts (万千瓦); if I have the units correct, that’s 14200 gigawatts total fossil generation capacity, increased by 54 gigawatts, vs. 256 new gigawatts solar. More than half of all installed renewable capacity is wind (486GW) and hydro (431GW) so the 22.1% capacity factor I calculated from the other press release is probably mostly due to hydro’s typical 90+% and wind’s typical 40+%, with solar still down in the teens. If we assume 15% for solar and 700 gigawatts as the average installed capacity over the year, we would have 105 gigawatts of generation on average, which would be about 10% of the 1.08TW total inferred from the earlier press release. At 48% per year exponential growth, in 49 months (02028) they’d get the majority of their electricity from solar, and in something like 6 years (02030) the majority of their energy. #photovoltaic
353MW Walla Walla #solar #photovoltaic farm in Riverina, New South Wales, #Australia, “consisting of approximately 700,000 solar panels installed across 605 hectares,” comes online, the biggest of the eight solar farms built by Spanish company Fotowatio Renewable Ventures (FRV). No notes on contract pricing. #energy
A 30MW #solar thermal power plant in Port Augusta, #Australia, by company Vast Renewables, “the first large scale #solar-thermal project in the country”, may get funded, but it apparently needs [AU]$360–390 million? Which would make it AU$12–13/W, which at 64.6¢/AUD would be US$8/W, about twenty times the price of #photovoltaic power plants (and 120× the price of photovoltaic panels). So it’s trying to get grants from the Australian Renewable Energy Agency (Arena). #CSP #concentrating solar power
“火电” redirects to “火力發電廠”, which explains, “火力发电厂（简称火电厂）或称化石燃料发电厂，是指靠燃烧化石燃料（煤、天然气或石油）来产生电能的热力发电厂。火力发电厂可以持续地穩定大量供电，在许多国家，大部分电能均由火力发电厂提供。”, which is translated as, “Thermal power plants (thermal power plants for short) or fossil fuel power plants refer to thermal power plants that rely on burning fossil fuels (coal, natural gas or oil) to generate electricity. Thermal power plants can continuously and stably supply large amounts of electricity, and in many countries, thermal power plants provide most of the electrical energy.”

#solar #photovoltaic wholesale #pricing is now €0.060/Wp for low-cost panels, €0.100/Wp for mainstream panels, and €0.130/Wp for high-efficiency panels. A year ago (November 02023), these were €0.10, €0.17, and €0.25, and two years ago (November 02022, when the cartel failed) they were €0.22, €0.34, and €0.43, roughly the same as when the cartel started; in November 02018, just before the cartel was announced at Davos, they were €0.20, €0.27, and €0.36.
#video by #Titans-of-CNC on #3D-printing with #binder-jetting, profiling a job-shop company in Ann Arbor named Azoth Digital Metal (Azoth being the alchemical universal solvent). The Markforged “PX-1 odger” (?) printer they like most can do up to 90kg in a single run, using 70400 nozzles each depositing 2.1 picoliters of binder at 15.5kHz, using air bearings and linear motors, as explained by Markforged’s bizdev manager for metal binder jetting, Ross Adams. Markforged’s technical director Hans Kimblad was also for some reason onsite, and also their president and CEO, Shai Terem. They’re printing small parts like firearm mag[azine?] releases, saying it’s much cheaper than machining but more expensive than metal injection molding. They’re also 3-D printing seatbelt parts that then get chrome-plated. They say they can hold tolerances of “plus or minus about three thou” on small features, ±75μm, “five thou would be typical”, and presumably even worse for large features: “I give people a 1% rule,” so a 400mm dimension would be ±4mm! “It’s a small complex metal part technology. So really I’m focused on parts 120mm in the longest direction, or smaller.”
#video by #China propaganda outlet SMG (Shanghai Eye) on 550-hectare #solar #photovoltaic farm in #Azerbaijan, in Gobustan, 60km southwest of Baku. Construction started in April of last year by #Dongfang Electric Corporation. Surprisingly, it uses solar trackers, so it may be able to get above-average capacity factors. Says it produces 500 million kWh of electricity annually (57 megawatts). Seems to be a pretty desert-climate site, but the total absence of vegetation (in contrast to the dry grass nearby) suggests it’s been bulldozed. The timelapse of construction doesn’t seem to show much in the way of concrete foundations, though the main control building is reinforced concrete with brick infill. Later (?) shots show vegetation has returned around the footings of the panels.
#video of a talking head claiming electrical #energy #pricing in #China is about 15¢/kWh, even though 20 years ago China was considered energy-poor. Also China consumes 26% of world energy (which would be about 5 TW), 55% of world coal (to India’s 12% and #USA’s 5%), and 15% of world oil (to the US’s 20%), according to the Energy Institute. Apparently the Chinese call their ultra-high-voltage #HVDC transmission lines a “Shinkansen for power”. The video author seems to be confusing HVDC with AC transmission. Claims #Brazil’s Belo Monte phase II HVDC transmission line is operated by the State Grid Corporation of China!
