Just as it sounds, this technology prevents CO2 from being emitted into the atmosphere by capturing it and storing it, often underground. The carbon footprint of the Clydeside campus is even bigger once the nearby Crowne Plaza hotel is factored in. Journal of Cleaner Production, 87, pp.263-274. Lignite powerplant with only 28% efficiency is the worst power plant possible. Save the Planet: Using Alternative Energies applies the NCTE/IRA Standards to science and social studies content. We also offset the carbon footprint of our headquarters in Pennsylvania with renewable energy certificates. 4 August 2014. The human population in the USA averages approximately 328,157,634 people. An individual wind turbine has a relatively small physical footprint. Global Footprint Network carbon footprint calculator is a feast for the eyes. What we are basically doing now, by burning fossil fuels, is recycling a small proportion of the extra CO2 that was in the earth’s atmosphere during the Carboniferous Era. 257287 KILOwatt-hours is 257 and a bit MEGAwatt-hours. Metal emission stats from page 25 from the 2006 IPCC Chapter 4 Metal Industry Emissions report. I Yes, but the wind turbines are sold as the saviors of the earth because they produce “no” CO2. The suffering of neighbors is very real. In Britain, before the start of the industrial revolution, the forests were becoming depleted through over-exploitation. A 1 megawatt wind turbine obviously must take at least 257 hours to generate this with ideal wind conditions. In the case of mail.com, our data center in Kansas – which has an annual power consumption of 13 GWh – has been using 100 percent wind energy since 2020. Wow that’s a bit deep for me, but thank you for mentioning fly ash in your statement. Stopthesethings: GREAT article. Yet under Mr Trump the USA reduced theirs and grew the economy. In fact, this type of analysis constitutes an entire branch of research known as “life cycle assessment,” with its own handbooks, internationally agreed-upon standards, specialized software, and peer-reviewed journals. What’s the basis for the comparison? That has to occur because wind power output varies so wildly dispatchable power must be always available to prevent total grid collapses as happened in South Australia last September. The fact is that energy is the only thing consumed in any operation and that is what determined the price. Classification societies can play a significant role in helping offshore with its decarbonisation challenges, says Mark Tipping. Sorry, your blog cannot share posts by email. Heath also found nuclear power’s carbon footprint was close to wind’s at 12 g CO2/kWh. What is the breakeven time needed to when wind generators actually do good? Would love to see an analysis on the impact all of that had on the CO2 emission reduction of that one limited lifetime generator. A 1,000-megawatt nuclear facility needs just over one square mile. Just as, whether we believe Al Gore (or better, James Hansen) or not, the fact that the fly ash from coal burning carries more radioactivity that a comparable nuke plant is permitted to emit, is a mere trifle compared with the poisonous gas emissions from sulfur, nitrogen, and even the neurotoxic mercury. Wind power pioneer Henrik Stiesdal is developing an aviation fuel from agricultural waste and … The conventional generation that exists and which must always exist to ensure power is delivered according to demand and not the weather? With Prime Minister Justin Trudeau promising to reduce greenhouse gas emissions and Alberta's plan to impose a broad carbon tax and eventually end coal-fired electricity generation, wind energy … The RSPB and green energy company Ecotricity have submitted a planning application for a wind turbine to be erected at the charity's head quarters in Bedfordshire. ( Log Out /  While new wind farms are going up, America’s first generation of wind farms are reaching retirement age, like the Xcel Energy’s Ponnequin Wind Farm on the border of Colorado and Wyoming. Check it out.. You really need to look at the carbon footprint of the composite materials used, and the mining and refining of the various alloys too. And land so alienated by roadways and use limitation, that food and fibre supplies are reduced. There is a plug at the bottom of the reactor that will melt if something goes wrong and dump the contents into a holding pit.The radioactive isotopes produced are needed for nuclear medicine. Check out SF6. Thorium exists in its structure in the same isotopic equilibrium as its stated in the periodic table. Reblogged this on Lauren Creech's Random Thoughts. Wind farms are preferable in coal dominated systems because coal fired power plants are twice as carbon intensive as gas power plants. Thank you again Global attention around carbon emissions is influencing how hydrocarbons are used and produced. A coal fired plant generates 2 things that concern you: CO2 and meaningful power available 24 × 7, whatever the weather. Step 1: Change your energy supplier. It’s true that wind power isn’t a zero emission energy source. Change ). THE CONVERGING WORLD tells the incredible story of one community's attempt to change their world for the better. It’s one of the easiest things we do to be sustainable. This is the oil that, when it catches fire, falls burning from the 100 mtrs high towers. The U.S. Manufacturing Energy Use and Greenhouse Gas Emissions Analysis report expands on the Energy and Carbon Footprints that were based on the 2006 EIA MECS data to trace energy from supply (fuel, electricity, and steam) to major end-use applications in U.S. manufacturing. When cement is mixed with water, sand and gravel forms the rock-like mass know as concrete. 8james38, Beware that Monazite, the main source for Neodymium (Bastnäsite its also an important source), does not have only Thorium in the Cristal structure. Germany has added 30,000 wind turbines and millions of solar panels to a coal fired grid and its carbon dioxide gas emissions continue to rise and are magnitudes higher than its nuclear powered neighbour. We don’t mean to advance the ’cause’ of any particular power generation source, but to be meaningful it must be available on-demand and affordable to all. Coal-fired power plants fare even more poorly in comparison to wind, with estimates ranging from 675 to 1,689 grams of CO2 per kilowatt-hour, depending on the exact technology in question. Which is around 0.15% of the life of turbine. Thanks, @stopthesethings for having a wonderful presentation on how much carbon wind turbine is going to produce. Band wagons are easy to jump on. Plants are ramped up and down, running inefficiently as a result and CO2 emissions increase across the power generation sector as a result. 3. University invests in campus renewables to reduce carbon footprint. Maybe they are not built in the cities because the majority of their biggest fans also happen to live in the cities! All this for an intermittent highly unreliable energy source. In brief, to reduce your carbon footprint, you’ll want to do things like reduce the amount of energy you use, eat fewer animal products, shop locally, travel smart, and reduce your waste. Just curious as to whether the calculation includes the front-end Co2 generating components such as the primary Resource Mining activities. We verified his statements using an audio recording of the event sent to us by Time reporter Justin Worland. And if CO2 is the culprit, then nuclear power generation is the only solution in the electricity generation sector. ( Log Out /  What action do you recommend to address climate change? You have missed out the unknown effect of noise and vibration pollution to sea life. It is NOT the problem that is portrayed by the doomsayers. Just look for publications like this; https://foreignpolicy.com/2017/11/13/germany-is-a-coal-burning-gas-guzzling-climate-change-hypocrite/ No idea how far they had to travel. In the first place, Thorium is hardly radioactive at all. Tom Toro is a cartoonist and writer who has published over 200 cartoons in The New Yorker since 2010. According to the EIA, there are two coal power plants using this technology in operation in the world – one in Texas and one in Saskatchewan, Canada. • Wind. Renewable energy industries provide a booming field for future scientists and engineers. This book shows kids these future jobs and gets them excited about contributing to a world run on clean energy. Added July 1, 2021: Reader Bill R. writes, “One thing you didn’t mention, and it is probably significant, is that as the energy mix tilts in favor of renewable energy over time, the energy mix used to manufacture wind turbines (and PV cells & panels) will also see a reduction in carbon intensity, resulting in an even smaller carbon footprint. Wake-up people! As you point out you have not in detail calculated other emission costs, and the cost to the environment of such things as ‘value adding’ the raw rare earth materials for the magnets. In 2019, just under 20% of the UK’s electricity was generated from wind power . (typo) Sorry I mean 10.7 Days and not 10.7 Hours*, Super excited?? Fossil fuels are, essentially, stored solar energy. As for the downtime issues with wind, yes, and there are times when wind provides too much power. 30 years? The National Renewable Energy Laboratory has a superb, though a bit dated, page on that topic that is well worth exploring. The climate changers are telling us that there will be more and more freak weather events in future. DOI: 10.1016/j.jclepro.2020.120159 . It is not fissile, but is fertile, meaning that it cannot sustain a chain reaction, but under sufficient neutron bombardment in a reactor, can be converted into a fissile fuel. This book examines, through a case study approach, opportunities to influence energy consumption in housing and buildings and thereby provide options for implementation at a macro, meso and micro level. The UK is the world leader in wind farms based at sea. Produce Hydrogen, build decentralized hydrogen power plants and use them in place of coal and natural gas/nukes to bolster the grid when wind isn’t supplying enough. 1. impossible to tell. P.S. **This is the chapter slice "Is the Future Green or Grim? We take it you’re not presently in intensive care on life-support relying on wind power alone, then? Email addresses are secure - and will not be passed on to any third party. And surprise, surprise: 25% of that of solar power! Large scale wind farm development proposals in Scotland have raised concerns about the reliability of methods used to calculate the carbon savings associated with wind farms, as compared to power derived from fossil-fuel and other more conventional sources of power generation. How Much CO2 Gets Emitted to Build a Wind Turbine? Let’s say you are right (i believe you are) that a wind turbine manufacturing produces 241.85 ton of CO2. Here is a practical thing we can do by adopting a precautionary approach against climate change. I knew some of the basic information, but I never bothered to put all together. Like all projections from wind companies, it is grossly over estimated for output of power; and underestimated on costs – some of the pads at Macarthur took upto 1100cm3 of concrete – as it kept disappearing in the softer country. To be clear, all of these figures are median, or midpoint, estimates, among a range of estimates for each type of energy. Food is a major contributor to carbon footprints, and meat in particular is an issue. Like…… China is trying to stop the mining of this magnetic material.. they have a lot of health defects from their water source… Everyone is getting white hair and way worse effects ….. To release 241.85 ton CO2, it will have to generate: 241.85*1000/0.94 bear with me here! ... for example by reducing the carbon footprint of … I think that this is a mistake. The energy return on investment (EROI) for wind energy is equal to the cumulative electricity generated divided by the cumulative primary energy required to build and maintain a turbine. The present LCA is composed on a comparative base in the field of wind energy, assessing an onshore 2MW and an offshore 5MW wind turbine. Make travelling carbon-clever. Offshore wind farms. As part of our pledge, we will make changes in the ways we produce, transport, and power. You’re still wrong for the reasons expressed in our reply. Since 2015, Apple’s Supplier Clean Energy Programme has helped our manufacturing suppliers transition to renewable electricity generated from solar, wind and other renewable projects. There is a blooper in the calculation. I never see it cited anywhere. If we pull all of these assumptions based on US data together, we can calculate the energy intensity and carbon footprint of the various water supply types as follows: Thus, according to these assumptions, the energy used to produce one liter of desalinated water, the most energy-intensive … The MSR/LFTR (Liquid Fluoride Thorium Reactor) is a totally fail-safe reactor that cannot melt down (the fuel is already a molten salt), needs no giant containment structure since it has no water in the reactor, and is about half as expensive to construct as a “conventional” PWR (Pressurized Water Reactor). However, unlike the area occupied by roads and pads, the total area is more challenging to define and subjective in nature. Coal and gas deliver power 24 × 365, irrespective of the weather or time of day. And don’t forget the waste from the extraction of rare earth metals (namely neodymium in industrial wind turbines) accumulating in a huge radioactive toxic acid lake at Baotou in Inner Mongolia. Not a smart move when the Royal family are promoting the Queen’s Commonwealth Canopy project on the other side of the planet. http://conservationvolunteers.com.au/green-army/. Good news: amortizing the carbon cost over the decades-long lifespan of the equipment, Bernstein determined that wind power has a carbon footprint … “… Life Cycle Energy and Carbon Footprint of Offshore Wind Energy: Comparison With Onshore Counterpart. How much of the UK’s electricity comes from wind power? =257287.234 kWh (units) of electricity. Solar energy made up only 1.3 percent. Thirdly, and perhaps most importantly, ‘the voters’ are either too busy and too far away from wind farms to bother delving for facts. Please any one advise. The rotor assembly for one turbine – that’s the blades and hub – weighs over 22,000 Kg and the nacelle, which contains the generator components, weighs over 52,000 Kg. "The carbon footprint on wind [energy] is significant. Reblogged this on Climatism and commented: What happened??? So what is the solution to that? IPCC Report on sources, capture, transport, and storage of CO2, for researchers, policy-makers and engineers. An examination and exploration of the issues that the Chicago Climate Action Plan (CCAP) deals with and how they may be implemented [1] Gavin Shire, a spokesman for the Fish and Wildlife Service, told us over the phone that the maximum estimate is 679,000 bird deaths. This … Coal’s carbon footprint is almost 90 times larger than that of wind energy, and the footprint of natural gas is more than 40 times larger, according to the Department of Energy’s National Renewable Energy Laboratory. The solution is that the massive education of ‘the voters’ and their civic leaders as pursued by STT and others who ‘actually know’ (and who are now getting to be a ‘critical mass’) about the massive ‘wind power scam’ must continue. The more dependable alpine Hydropower and nuclear stations have median total life cycle emission values of 24 and 12 g CO 2-eq/kWh respectively. 240 Kg of CO2 is emitted for every cubic metre. The ONLY justification for wind power – the massive subsidies upon which it entirely depends (see our post here); spiralling power prices (see our post here); and the suffering caused to neighbours by incessant low-frequency noise and infrasound (see our post here) – is the claim that it reduces CO2 emissions in the electricity sector. we must not forget the human labor and travel required to install and maintain one of these as well. Andy’s Rant. I’m trying very hard to support you. Climate change : what's the big deal? to get an honest annual output of that turbine we must subtract what that wasted back up energy could have produced, anything over that is the power benifit to the grid, the answer is dismally small. It includes a case study of the mid-Atlantic highlands, a mountainous area that spans parts of West Virginia, Virginia, Maryland, and Pennsylvania. This book will inform policy makers at the federal, state, and local levels. The study, published in the journal Nature Energy, calculates the lifecycle greenhouse gas emissions … I am curious to see a comparison CO2 impact of the construction and maintenance of a coal and natural gas producing plant. Thanks. The amount of Diesel Fuel required is? A typical wind farm of 20 turbines can extend over 101 hectares of land (1.01 Km2). One study put that payback time at seven months — not bad considering the typical 20- to 25-year lifespan of a wind turbine. Burning coal and other fossil fuels has basically protected Britain’s forests from total destruction 2-3 centuries ago. And they haven’t got the maturity or grace to admit it. One cubic metre of concrete weighs approx. When we contacted the DOI for support for Zinke’s claims, spokeswoman Heather Swift told us by email that, when it comes to wind’s carbon footprint, Zinke “was referring to the life-cycle emissions, manufacturing of materials and component parts, and the transportation and construction of the facilities.”. In the post above you will not have studied the data or analysis in these posts: https://stopthesethings.com/2015/07/20/the-wind-power-fraud-in-pictures-part-1-the-south-australian-wind-farm-fiasco/, https://stopthesethings.com/2015/07/21/the-wind-power-fraud-in-pictures-part-2-the-whole-eastern-grid-debacle/. Offshore near some coastal cities seems viable. With a lifespan of only fifteen years, running at max 30% output, an industrial windmill could spin until it falls apart and never generate as much energy as was invested in building it. Coal power plants using carbon recapture and storage technology do produce significantly lower emissions than standard coal power plants, though still more than wind power. I’m all in if wind power turns out to be more carbon intensive than fossil fuels but you don’t have me any where near convinced yet. Carbon debt. A small plant will have a 10 inch natural gas line firing 24/7 continuously. So what’s the carbon foot print of a wind turbine with 45 tons of rebar & 481m3 of concrete? They are sick and helpless now and the rich neighbor says tough break. Have long wondered about the what the real cost of manufacture of turbines v their actual output …. To put this into context, estimates of life-cycle global warming emissions for natural gas generated electricity are between 0.6 and 2 pounds of carbon dioxide equivalent per kilowatt-hour and estimates for coal-generated electricity are 1.4 and 3.6 pounds of carbon dioxide equivalent per kilowatt-hour*. AT – https://www.telegraph.co.uk/news/2019/09/13/worlds-powerful-greenhouse-gas-rise-due-green-energy-boom/, Hi, thanks for these facts.
