i want to know about the main drawbacks of producing electricity with help of windmills or in other word i would like to know about the main drawback of a windmill
PLEASE TELL IF YOU KNOW ANYTHING ABOUT IT!!!!!!!
Who am I ?
Hi, I’m Erik Astrand and the man behind this site.
My story? I am about to be 50 and all my life I have been interested in technical things. Not sure if the special interest for the wind, and how to use the wind, started when I as a 5 year old boy and got my first sail dinghy.
Anyway, wind power and to build my own wind generator was a dream for several years. I studied many websites and also bought many courses before I finally built my own windmill. This site is about that journey and you will also find some more general articles about wind power.
Enjoy! and check out the about me page to read more.
On top of those great answers:
1. How are windmill parts, blades, wiring, metal casings, tower frames, ball bearings and other parts manufactured? By petrochemicals and energy.
2. How are all these parts put together and setup? Trucks that use oil move the parts. Workers who set up the parts into windmills use oil to get on location, usually far out of the way places.
3. Parts wear and are damaged by weather and other causes and thus must be replaced on windmills.
For example, it takes labor, water, and oil/mineral spirits as well as energy to manufacture a set of precision bearings. These bearings must be replaced 4-8 times a year depending on wear, as well as must be inspected bi-weekly- meaning more fuel being used.
4. Cost. Way too expensive to really use and the technology as far as the windmills themselves is pretty much as far advanced as it is going to get. Improvements on energy storage is still possible, but guess what? Once a super energy storage technology is invented, windmills would be way inefficient energy generators once good transportable energy storage is invented.
Because the wind doesn’t blow all the time. worse, when there is a calm, it can be calm (no wind) over hundreds of square miles.
So unless we all want to stop using power when there is no wind, there has to be alternates.
Wind turbines are also very expensive, take a lot of maintenance, are noisy, and are considered by many to be ugly and disfiguring of the views.

The primary drawback is that the wind doesn’t blow all the time even where the wind blows a lot. And, it doesn’t blow on schedule when we need the power. Therefore, standard gas and coal generating stations need to run all the time anyway to back up the wind mills. It takes several hours, if not days to get conventional power stations up and running so they can’t be shut off completely when wind generators are producing power. Second, there currently is no efficient way to store electrical power from wind generators so that power generated by the wind when it is not needed can be saved for later. Of all the ways to generate electricity, wind power is probably the most expensive and least reliable. Without massive government subsidies no one would even consider it except Greenies who traditionally rely on other peoples money to finance their absurd schemes.
