The Wind Energy Reddit

Wind Energy is the use of wind to provide the mechanical power through wind turbines to turn electric generators and traditionally to do other work, like milling or pumping. Wind power is a sustainable and renewable energy, and has a much smaller impact on the environment compared to burning fossil fuels.Wikipedia: Wind Power

Wind energy penalty? Fluid dynamics?

Backstory: In a thermodynamics class for refrigeration, the question of the energy penalty of wind turbines (among other renewables, but wind took center stage) was asked and we parsed available data (WEF 2021 data= 5 billion horsepower of wind energy harvested etc..). The following weeks lecture, the 3rd in a series of fluid dynamics, in which thermal stratification and thermal pocketing in closed systems (industrial process refrigeration, large refrigerated storage etc...) were discussed and solutions examined. This all led to a sidebar discussion on the fluid dynamics of the atmosphere. The discussion persisted for the remainder of the semester and the following semester some of those returning students selected this topic for their research paper. Using a simple information modeling process and a few lab experiments involving flow hoods, fans meters etc...it was determined the energy penalty was less than .0001% (using 10,000 ft of troposphere for volume and avg wind speed of 15mph) and NO disruption to stratification of the fluid system. However, when clustering the wind energy harvesting to smaller areas, significantly smaller areas (<80,000 sq miles) energy penalties of as much as 15% were observed. In our field, disruptions of flow by as little as 4% allow for pocketing and disruption of stratified fluid streams.

The question is: Has anyone else been down this rabbit hole? If so, to what end? The availability of white papers and journal entries regarding this are non existent and engaging in conversation with colleagues in the geo sciences never goes anywhere (cant touch the golden calf, wind energy). Lots of research on wind turbines, their wakes and efficiencies. Less on fluid dynamics in stratified systems.

The students concluded (always quick to form an opinion) The wind energy penalty was enough to cause thermal pocketing in the troposphere, which in turn would cause a ripple effect through the layers of the atmosphere all the way up, to the jet stream (layered fluid system). This would explain the weather anomalies we have been experiencing as of late, including the first ever recorded breakup of the jet stream in summer of 2023.

Radiation is the least productive form of moving heat and convection is the best, conduction in-between. Perhaps the distribution of heat throughout the system has been adversely affected. Or, perhaps, the 10,000 MTOE of energy consumed in this world in 2021 has resulted in too much heat for the system to handle...

I have no conclusion or opinion, however intrigued and engaged. What say you?

Interview questions as wind and site expert

Hi fellows,

Is there anyone here who works in wind energy or wind parks as a wind and site expert? Could you provide some guidance on the day-to-day tasks involved in the field? I come from a meteorology background and don't have access to tools such as Windpro or about what type of data is used and how I can best prepare for such a job.

Thanks

Renewable Energy For Flat

Hi everyone.

I live in a flat which has a balcony, and I'm looking for advice on getting a wind turbine which can store energy and I can then use. The flat is on the third floor, and the electric meter is on the ground floor. Anyone had experience of a wind turbine which is a reasonable size and could be placed on a balcony?

I know the management of the building won't allow any connection to the electric meter but is there something that could be used to store energy and I could then use?

Aspiring maintenance technician

Hi all, I wanted to throw this out there just in case there is anyone out there that is able to help point me in the right direction.

I have a large interest in pursuing a career in Green energy and my particular interest lies with becoming a wind turbine technician/engineer. Due to working full time, I have been finding it hard to find courses that offer me both knowledge training and practical training. In the new year I am looking to start an online level 3 foundation diploma in engineering.

My question is to whether or not this course will help towards becoming a turbine technician/engineer. I'm also wondering if anyone knows of what sort of experience I can get whilst working full time?

Any help is appreciated, thanks everyone!

Educational Wind Energy project

Hi,

I want to kick off a long-term wind energy project with my kids, focusing on both educational and practical aspects. This is not just a one-month endeavor but rather a multi-year journey. My kids will gain various skills, from planning and theory to practical application and data analysis. The project aims to explore wind speeds, directions, and the efficiency of different types of wind generators, as well as electronic and software skills and everything else along the way.

The Big Picture The idea is to start small and gradually scale up. I've initially settled on low-speed wind turbines for safety reasons.

Educational Goals This project aims to provide a hands-on learning experience for my kids. We will be covering various topics like electricity, magnetism, hardware, software, and more. While the project might produce some real-world application, its primary goal is educational. It shoulnd just be a toy, but it will also involve scaled-down 3D-printed models for comparison.

Energy Storage & Data Logging Initially, the focus won't be on energy yield but rather on collecting and analyzing data. If we go for a real-world system, we're considering a 12V setup with ESP32 units for data logging and MQTT for integration into HomeAssistant. In the case of scaled models, a 6V system would be more appropriate.

Why Wind Measurements? Wind measurements are critical for establishing baseline data and making comparisons later. We're currently evaluating the project scope, and while we haven't made any purchases yet, we're in the planning stages.

Software and Tools I'm currently learning SimScale for fluid dynamics to better understand the airflow around the turbines. The models will be created in Fusion360, and then tested in SimScale for further refinement.

If anyone has something interesting to contribute, please feel free. I'm currently evaluating the concept and taking everything in that comes my way.

Hello, I hope everybody is doing well!

I'm currently enrolled in a master degree in engineering physics (renewable energies specialization) in Germany (I have a bachelor degree in mechanical engineering). I'm quite interested in the wind energy industry and research. I want to ask the experienced engineers and scientists about the current high-demanding skills and high-paying jobs in this field. I have a wide range of modules to choose from for this master; therefore, I want to choose well to have a good background for my career. Also, what do you advise me in general to excel in this career—what kind of things I should learn alone, skills, and online courses I should take? I will appreciate any advice from you guys. Aerodynamics, aerospace, and artificial intelligence are areas of interest for me. (But I don't have relevant work experience.)

I'll give you an idea of the modules available:

How do wind turbines store energy in the real world - not theoretical.

I am an electrical engineer, so I know a little about power generation, etc. This past weekend I got into a discussion with someone about windmill farms, and they were asking me some basic questions about how they work, etc. One thing I was not very sure about was how and if these windmill farms store energy.

I have done a little research on-line and I can't find a solid, satisfactory answer. Some sources say they don't store energy - they just put it directly into the grid. Other sources say they use storage methods ranging from batteries to compressed air. So I don't know what the real answer is.

Can someone give me a more solid answer? They were particularity asking about the windmill farms they see in Illinois and Iowa.

Floating offshore wind energy - Will it scale or is it just another renewables fad?

Floating offshore wind energy is either described as another unscalable 'renewable fad' or as the only way forward of wind energy. It's seldom placed within the spectrum of these extremes.

There are currently three commercial offshore wind farms in operation in the UK and Portugal, with a number of others close to deployment, mostly in the Europe.

Advantages of floating turbines include tapping into more consistent mid-sea wind resources, no need to assemble offshore (can be assembled at port and towed to location), and there are no foundations needed, so no disruption to seafloor ecosystems.

On the down-side, it's still expensive (classic), it is less efficient as it's a dynamic structure, and onshore interconnection is resource-intensive, expensive, and vulnerable to sabotage.

New project ideas

Hello Reddit,

I am currently working for a subcontractor company that has recently entered the wind industry. Our company is currently engaged in maintenance activities and we have just started working on construction projects as well. Our company owner has encouraged us to come up with new ideas for projects. I would like to propose some potential projects that we could undertake. One idea that I have is to start offering hoist and ladder inspections. However, I would like to hear more suggestions from you. Can you provide me with other ideas that we could explore?
