As usual at first piles field is organized then pit base slab and after rebar reinforcement and pouring. On my opinion when wind speed up to 30 m/s wtg will overturn
After the end of the life of the wind turbine, do they return the land to its original condition (i.e., remove all the the concrete pilings and foundation) or do they leave the concrete footing behind?
hi Juan. glad you like the video. the site is southwest of Glasgow in Scotland. the foundation took 3 weeks to build and the turbine took 1 week to build. once it was up there was another 3 weeks of electrical work and commissioning before it started generating.
It took 2 weeks to build the foundation and 1 week to build and commission the wind turbine. It's on the west coast of Scotland. Thanks for your comment :)
You can find a list of renewable energy degree courses in the UK here: www.whatuni.com/degree-courses/search?subject=renewable-energy-resources Some unis also offer wind-specific courses, such as this MSc at Strathclyde University in Glasgow: www.strath.ac.uk/courses/postgraduatetaught/windenergysystems/
I lived around a wind turbine and the worst was the leaks, which they never tell you about. My daughters and to go to school covered in oxygen. And they had to walk by a solar farm and their skin was darkened by the emissions. God, it was horrible. They used to have sunny day alerts. They have been scarred for life.
@@locogen7910 hello, please is there a school where one can learn everything about wind Turbines or do you know of anyc company that can teach, I'm interested please.
@@princeleye9515 hi which country are you from? In the UK most schools teach about renewable energy. If you do an engineering degree it will cover wind turbines. Mine degree had a whole course on each type of renewable technology. It was very interesting.
This is the coat of one built in the U.S. currently. "The costs for a utility scale wind turbine range from about $1.3 million to $2.2 million per MW of nameplate capacity installed. Most of the commercial-scale turbines installed today are 2 MW in size and cost roughly $3-$4 million installed."
@@locogen7910 Why "if that's true"? How does bulldozers that scrape and transport rare earths essential to build wind turbine work? With oil. How does the boats and trucks that transport wind turbines work ? With oil. How do the people working on building and installing wind turbines go to work? With a car using oil in an internal combustion engine. There is no question "if" that's true. That's true.
@@superpieton for now but not forever... Many people drive to work in electic cars. We have a hydrogen ferry powered by hydrogen produced from wind turbines and electrolysers operating in Scotland. We have hydrogen and biofuel plant and machinery. It's all new at the moment but it is moving in that direction. It may take some time but we will move away from oil and power the world with renewable energy. And so what if some fossil fuels are used in the supply chain for the moment, as long as we are constantly reducing it there will be a reduction in CO2 emissions. It's doesn't have to be all renewables or nothing at all.
@@locogen7910 1st mean of H2 production in the world is steam cracking H4 (methane). It gives H2 + CO2! H2 is not an energy, it is a vector: you need energy to produce it, there are no wells of H2 in nature. And why is this so important that renewable can't exist without oil? Because peak of conventional oil was in 2008 and peak of unconventional, originally predicted for circa 2025 seems to have been passed in the last quarter of 2019...
It's widley accepted that the carbon payback is 2.3 years. See here for a latest study on a Scottish wind farm where the carbon payback was calcualted to be 47 days (bit.ly/2FzmILg). So it does depend on the specific project, but it is usually within only a few years. Certainly better than coal :)
@@intelligenceservices yes there are many comprehensive studies that encompass manufacturing, transport, construction and in-life costs. The carbon saving though also is dependent on the carbon content of the grid electricity in the country. So countries with more coal generation will have a quicker payback than companies with more nuclear or renewables.
@@intelligenceservices ultimate the sun causes wind. Electricity is a form of energy which is converted into other forms of energy and sometimes that is waste heat, as you point out. It can be recovered and used, but that doesnt happen often. It should be recovered to help improve efficiency and reduce waste :)
We install refurbished turbines as well. These are machines that have been taken down from an old wind farm, refurbished by an engineering company and installed at a new site for another 20 years. They offer a great opportunity for local business and community groups to invest in wind energy and provide power to their local area 😀👍
@@bubba842 Well since they are not made mainly of steel I'm going to assume you have no clue what you're talking about and you're just trying to be a know it all, do some research and try harder next time junior :)
It's not ment to compete with nuclear. Nuclear will always be used as a base load for the grid since it is very hard to increase the output of a nuclear power plant in a small amount of time. Wind is there to replace coal and natural gas powerplants. If you don't think it can look at the UK. 2019 the UK had
It's quite easy. Basically it's the installation process in reverse. It takes about 3 days to remove the structure above ground. The foundation is not normally removed below 1m in depth but if needed it can be broken up and recycled as a sub-base in roads. It's really not that difficult or expensive. We have to put a decommissioning bond in with the Council to ensure we remove it at the end of the life and if we don't they use the bond to remove it.
