In the debate about renewables the opponents drone on about the turbine only lasting 20 years and filling a landfill with plastic. I know they tend to have their facts wrong on these but what's the real deal if we make a big investment in wind turbines?

Seems to me the concrete base and the tower could be built to last 100 years. The generator is mostly renewable metal. That just leaves the blades. I understand that composites are the best choice for weight but are there any developments in making that part renewable as well?

Hi! As part of my job for a nonprofit I work for, I am looking to hold interviews with land owners that have installed wind turbines onto their land.

The interview should be no longer than 5 minutes.

I am primarily focused on speaking about the financial benefits you have gained from integrating wind energy.

I’ve been thinking about how critical components impact cashflows, especially with fluctuating demand and supply delays. It feels like balancing what’s vital or scarce with cashflow forecasting is a constant juggling act. Has anyone tried VED/SDE analysis for managing inventory and cashflows? Would love to hear how it's working for you!

Tesla is a world leader in EV’s, industrial size Megapack battery systems for wind farms and grid storage and is also becoming a leader with Powerwall domestic battery systems and solar panels.

But why do you think Tesla invested in the construction of Tesla Wind Turbines and Wind Farms?

I’d like to see Tesla build a large wind farm near the site of all or most of their Gigafactories, as well as other large Wind Farms to help generate the additional electricity that will be needed for millions of additional EV’s worldwide.

Hey👋 , Can anybody guide me how to download windPRO free to use

I live in a vineyard house in a remote location with a 12x 455W off-grid solar system and 4x 12V 200AH deep-cycle gel batteries (connected in series for 48V, total 9600Wh capacity). While this setup meets my current needs, the area is extremely windy, and I'm considering adding a small wind turbine to support my batteries.

I'm looking for a turbine that could generate 150-300W during windy periods. This would help keep my batteries near full charge at night, which is ideal since my main power draws are just a PC and a fridge.

My current plan is to connect a wind turbine to a small 48V charge controller and then directly to my battery array. I can install the turbine at a height of 10-15 meters without any issues.

My questions are:

1. What kind of turbine would you recommend for this setup?
2. Is this approach feasible, or even a good idea?
3. Are there any potential issues or considerations I should be aware of?

Any advice or experiences from those who have implemented similar hybrid systems would be greatly appreciated!

I live near a huge (15 mi x 15 mi at least) wind farm in Northwest Illinois. For the first time I've ever seen all of the wind turbines are stopped cold. Could this be part of the Crowdstrike outage?

Hello people, I am currently a highschool student ad I decided to do a research paper on which angle of attack of wind turbine is the most efficient for electricity output. I search the internet but I could not find any concrete information. I even constructed a small version of wind turbine but I do not know how reliable it is. Could you please help me with this question?

Hello everyone, I am pretty new to wind turbines word, so I'm here seeking for some suggestion.

• The first question is related to the type. Atm, There should be these types available: Diarreus, Helical H, Rotor,Savonius. Which kind seems to be the most efficient one?
• Second question. I'm a bit confused regarding which parameters I should take care to evaluate the quality of these turbines. In the image below, I will share the Darrieus-type parameters from 0.4 to 2 KW. I am concerned that at the Rated Wind Speed, they wouldn't produce neither 50% of their Rated Power. What do you think of, for example, 1KW model? What should I take car of when I see all these datasheets?

Thanks everyone!

I mean, it makes sense considering that permanent magnets wear out over time and our neodymium and praseodymium supplies are hard to come by. Why not?
