And we still haven’t paid for a single wind turbine or solar panel, or their installation and transmission infrastructure, or acquired the land or sea bed they would be built on. They did increase because of first mover disadvantage. In NL and Germany those are used since decades. The most expensive FiT contracts expire in a couple of years and there is surplus money already collected via the subsidy tax which may be used starting soon to lower the amount charged. (See the Supporting Information as well as the short article.). The Rosetta Philae comet lander, whose battery was to be recharged by solar panels, became an expensive pile of junk when the panels ended up in the shade. Hinkley *still* has not received the go-ahead. 21. The Danish energy sector is annoyed by this and they are trying to get this changed. Let’s do a few sums to see if that assertion passes the sanity test. “Hansen refers to Lenzen solely…” First, consider the claim that renewable energy has no carbon emissions. The world is 40 000 km around. This report addresses the increasingly important interactions of variable renewables and dispatchable energy technologies, such as nuclear power, in terms of their effects on electricity systems. Although nuclear energy isn't considered renewable energy, it does not emit any of the greenhouse gases that contribute to global warming. US household…. Nuclear energy harvests the powerful energy in the nucleus, or core, of an atom. I’ve met many people who changed their mind about nuclear, usually gradually, about nuclear and lost friends and colleagues over it. You seem to ignore electrification and energy demand growth. ‘how that works’ doesn’t parse into a question I can answer. The data mining argument was used in the discussion about the the increase in m/f sex ratio of new born around Gorleben when the first nuclear waste castor’s were stored there in the huge building. The world is much more complex than some people think. Therefore it is inappropriate to ignore the proliferation risk, which is probability multiplied by potential impact. British Gas introduced a “read your (gas & elec) meter once per month, send the reading to us & we will give you a real monthly bill. - This Is Africa. Uranium and plutonium are most commonly used for fission reactions in nuclear power reactors because they are easy to initiate and control. 78. New Horizons to Pluto too. “At the global level, scenarios reaching about 450 ppm CO2eq are also characterized by more rapid improvements in energy efficiency and a tripling to nearly a quadrupling of the share of zero- and lowcarbon energy supply from renewables, nuclear energy and fossil energy with carbon dioxide capture and storage (CCS), or bioenergy with CCS (BECCS) by the year 2050 (Figure SPM.4, lower panel).”, https://www.ipcc.ch/pdf/assessment-report/ar5/wg3/ipcc_wg3_ar5_summary-for-policymakers.pdf. If … Hinkley *still* has not received the go-ahead.”, BBC Thursday, 10 January 2008, 17:41 GMT blockquote>What’s funny is that the whole PV industry exists because radioisotope thermoelectric generators were too unreliable for space missions and satellites. Facts and maths is all I have. Not one permanent repository is operating in the world. I’ve grown up around nuclear. Rooftop solar ‘behind the meter’ is competitive with retail grid electricity prices in many regions of the world with medium to high insolation, even where there are no feed-in tariffs. A factor of 4 over your cost assumptions. Energiewende = less fossil fuels! False Facts: Nuclear energy is one of the cleanest sources of energy in the United States, emitting no greenhouse gases when generating electricity. Myth 4: Nuclear weapons proliferation is independent of civil nuclear energy. ALI SWENSON and ARIJETA LAJKA, The Associated Press. False Facts: Nuclear energy is one of the cleanest sources of energy in the United States, ... they are all funded by fossil fuel industries or to support renewable energy. Particularly when Germany’s emissions haven’t decreased very much over the last five years despite billions spent on renewables support. The lines will be ready when needed. – France has some of the lowest cost electricity in Europe. While several European countries are phasing out nuclear energy, most growth in nuclear reactor construction is occurring in China, Russia, India and South Korea. In Australia they include two biologists, a social work academic and an occupational therapist. France’s wholesale electricity prices are higher than Germany’s. 46) found levelised power purchase agreement prices in 2014 for wind in the US interior (region with the highest wind speeds) of US$22/MWh, and in the west (region with lowest wind speeds) about US$60/MW. – part of the land occupied by uranium mines, processing plant, enrichment plant, fuel rod fabrication plant; ”. I’m not one to play fast and loose with figures on purpose but these are pretty accurate from recollection: Btw. Wind farms were simply scaled up at existing sites. Similar with floatovoltaics, which deminishes varpourisation of irrigation water, which increases the usefulness of the area occupied by existing irrigation systems. “Zentraler Grenzwertsaz” is the name of thoie phenomen in methemathics, Or, better still, use some dispatchable nuclear at 40g/kWh or better. Investors are turning their backs on nuclear power. Japan got no nuclear power for several years because atomic power plants were all going through maintenance, how reliable is that ? Mattias, your points: For this reason, supporters of nuclear energy argue it should be considered renewable. Then you can start building which took 30 years in France. The gaping hole in your cost comparison is that you disregard the cost of transforming intermittent renewables into a stable energy source. But once you get past 20% penetration, you simply have to rely on backup, almost always fossil fuels. “Nuclear energy is too expensive, more than twice as expensive as renewable energies,” says Claudia Kemfert, an energy economist at the German Institute for … From the above, I conclude that whoever proposed to underbid Hinkley with such proposals would rapidly lose their shirt. While we were being told it would make electricity 'too cheap to meter', insiders knew it cost at least 50% more than conventional generation. Nuclear power was originally sold on a lie, writes Dave Elliott. Elon Musk says the sun can power all of civilisation. The Netherlands: a Blue Hydrogen economy now will ease a transition to Green, An EU ETS that lifts carbon prices too high can make clean energy transitions harder. For Chernobyl, the lowest serious estimate of future cancer deaths was ‘up to 4000’ by the Chernobyl Forum (2006), a group of United Nations agencies led by the International Atomic Energy Agency (IAEA), which has the conflicting goals of promoting nuclear energy and applying safeguards against inter alia accidents and proliferation. They were then shut down for an extended period because Japan needed to get its nuclear regulation sorted out, and because of acute national radiophobia. Coal use decreased substantially as well as other ff. The current generations of new nuclear power stations are classified as Generation 3 and 3+. Solar radiation, dust, thermal cycling and weather takes its toll on solar installations. Nuclear is cheapest, fastest, and has the best EROEI of all technologies, even fossil fuels, in recent decades. I challenge anyone who has a large investment in “renewables good, nuclear bad” mantra to come out one day and announce to their professional friends and family, “Folks, after a lot of thinking, I realize I got this whole nuclear energy thing all wrong and we need this clean energy source just like any other we can get, I’ve changed my mind.” You can wave your hand and say it was an April fool’s joke if you aren’t sincere, but first play with it for a few minutes to see their reaction. Although nuclear energy isn't considered renewable energy, it does not emit any of the greenhouse gases that contribute to global warming. Computer simulation models and growing practical experience suggest that electricity supply in many regions, and possibly the whole world, could transition to 100% renewable energy. I made no such claim. Though now and during next decade the produced gas is injected in a natural gas pipeline. With thousands of individual generators that have thousands of connections to the grid, no single failure can shut them down. See http://ansnuclearcafe.org/2013/02/14/responding-to-system-demand/ . Nuclear energy is considered to be a clean type of energy when it comes to production. Seawater could serve as a source that naturally replenishes itself, making it a perfect choice for Uranium mining. Although nuclear energy itself is a renewable energy source, the material used in nuclear power plants is not. For a fuller exposition of the problems of IFRs and other ‘new’ reactor designs, see Amory Lovins’s classic 2009 essay, recently republished on The Ecologist: ‘ “New” nuclear reactors? B. At 50kW/PP2, we would need 20 x 1000 x 3.2 = 64,000 PP2’s to match Hinkley. less storage, the smaller likelyhood for rising sizes and times allows to use power generation modes with lower capacity prices but higher operating costs, like e.g. How’s that 12.5 GW (~20-5% CF) going to displace our 100 GW (85% CF) nuclear fleet? It is well documented by comparing the installation rates of wind capacity versus the overall retail cost of electricity, that a strong correlation exists between the two. 7) Ontario has decarbonized its electric sector (closed its last coal station) primarily on the back of nuclear, but should Ontarians do what the Germans are doing and shutter “perfectly good” nuclear plants only to recarbonize their electric sector? They used more info! Energy Conversion & Management 49:2178–99. https://www.irena.org/documentdownloads/publications/gwec_denmark.pdf. The same mathemathics, which causes that the output of a nuclear powr station is about constant over time, and that it does not happen that all atoms are spit in the same moment, or non at all for some time. Germany is showing the way what happens when stochastic RE reaches an unsustainable market penetration. It makes it almost impossible to understand a subject if you don’t have even the basic tools needed to talk about it. And the variability of the production is accurately predicted days ahead (thanks to improving weather predictions). Nuclear ower is ususally cheap before the project starts. If you want to argue emotions, you’ll need to find someone else. By the way, the value of the roughly 200TWh of renewable power in germany is worth baout 7 billion (Mrd) Euro, it would have a value of around 16-20 billion euro if there would be still the prices of 2008, which were on a level high enough to trgger the constructio of new thermal capacity. Shold solar produce constant output for 24/7/365, while demand is higher during the day and lower during the night, or follow demand? Having been asked to calculate out the overall full-lifecycle resource footprint of a renewable solution that can provide 5000MW of despatchable-on-demand power at 90% CF for the equivalent lifetime of an NPP, you reply that the area of the tower footing of a wind turbine producing a mere 3.45MW at a CF of 27% at the whim of the weather, is only 60 sq.m. In the US, this same lobby is the “democratization of energy” crowd, and they’ve amassed a jaw-dropping [sarcasm intended] ~12.5 GW of rooftop solar against a system size on the order of 700 GW base. We won’t need China’s piddly 1000 GW of Nuclear. And the majority of those taxes have nothing to do with energy. “Nuclear radiation from nuclear power plants & accidents is not dangerous.”, While it is shown many times that any increase in nuclear radiation causes substantial health and (worse) genetic damage! There is no problem with the CO2 emissions in the power sector there the CO2 emissions are falling.
