    Wind and Solar vs Coal, Gasoline, Nuclear

    Relevat for the thread: https://www.iea.org/newsroom/news/2019/april/key-electricity-trends-2018.html I note the last few years have seen steady relative increases in Wind and PV total generating capacity - ie. exponential growth! IF it was installed capacity it would be a lot less exciting...

    Looking at your chart, then the oil-use of 33% has to be managed. All the rest goes to heating and electrcity-generation, right? Coal, lignite, Gas = Electricity and heat in CombinedPowerPlants I know the last percantages are impossible, and the scale is mindboggling, but 2/3rds are up for...

    Arrg, come on, you can do better :-) Or is your understanding of economics as poor as it is of scientific methods? As readers are aware I was answering your false claims of "doubling and tripling in consumerprice at the meter within past 5-10 years in many western countries" - don't really like...

    For AU electricity Priceindex 2008Q1=339.24, 2013Q1=384.17, 2018Q1=423,17 Electric index: 2008Q1= 407.34, 2013Q1=745.38, 2018Q1=884,92 Adjusted increase = 7.7% over 5 years Adjusted increase = 74% over 10 years, AAAAND you run on coal..... Your reference to british costs is from 2013 - thats...

    Of course it does, inflation and income will correleate, and cannot over time change very much in a developed contry with stable economics. Please stop with this idiotic crap. Spewing nonsense, and not showing the facts. Show where the electricity-prices at the meter have changed by +100%...

    Sorry to bust your time in La-La land, but that utter and total bullsh*t - completely false. I know you are just repeating the same nonsense over and over, untill no one cares about your inane ramblings, but jeeez.

    Wind and Solar vs Coal, Gasoline, Nuclear

    In other news: Denmark just held a public bid for private renewable projects. It turned out to be 5 times cheaper than previous in terms of feedin-tarrifs. Technology was independent for bidding. Feedin ended up at basic sport-price (heavily linked to European Continent) + 0.028 dkr/kWh = spot...

    Wind and Solar vs Coal, Gasoline, Nuclear

    I like nuclear and all, but all the trolling from a certain fact resistant member, revolves around heating. Running a nuclear plant discharges a lot of waste-heat in the planet-system. The carnot-cycle equations are why a plant needs cold inlet-cooling to get a high delta-T. If not even larger...

    https://electrek.co/2018/11/05/tesla-shared-powerbank/ So, a virtual private battery? Battry storage in general are not economical for a grid, unless there is over-generation. But if there is, then growth of PV is less of an issue with these babies :lowbatt: :bolt:

    Wind and Solar vs Coal, Gasoline, Nuclear

    As a side note: Denmark (Birth home of Vestas, NEG Micon, Siemens WindPower etc.), now have a lot of landbased windmills exceeding 20 year lifespan. They estimated span for the installed turbines in 1995-2005 is 25-30 years! After 20 years all turbines operate solely on spot-pricing market...

    Yes, they are very anti-renewable which reads clearly in the abstract - so much thats it's cringelike to read. However they are not that far off wrt. silicium. A *LOT* of the Si is lost in the processing. creating wafers from ingots, grinding them, lapping them etc uses a lot of material. So...

    Wind and Solar vs Coal, Gasoline, Nuclear

    Economic theory and such would indicate that storage cost is viability is a function of price *variation*. The lower cost, the less variation is needed to make the solutions economically viable. Absolutely, its important. But its not that important. If you had exceptionally cheap storage, you...

    Everything is too low in a "free" market :shock: Teh reason is that hte true value and cost of burning fossil fuel is never imposed. Which value to put on a barrel of oil, when we potientially could "run out" of the stuff? in 50 in 500years - its still a problem! Which value to put on the...

    It's not "flawed". If no other easy option (hydro-power displacement etc) is available then thermal storage of electricity which would be curtailed is a good candidate. Yes better if the reject heat can be reused, but its all about the cost. If supplied electricity has marginal value of zero...

    Wind and Solar vs Coal, Gasoline, Nuclear

    When generating under big head-pressure, pelton-driven is most effecient. AFAIK its also more effecient under partial loads compared to nameplate rating. At medium pressure geenration Francis tubines are best. At low pressure its Kaplan turbines. Also the system has the possibility to keep the...

    Wind and Solar vs Coal, Gasoline, Nuclear

    Yes - the power is dirt cheap.... As in teh spot-price. Our average sport-price is very low because the consumers pay the PSO, and the grid is cheap. But we we're talking about grid prices and stability, and out grid is rockstable and cheap. Conveniently you try to misdirect. Thats you...
