Energy 101: Wind Turbines

[nmgscp]

Being the 5th wind-power producer in the world, I wonder when Portugal will also be a major producer of wind turbines!

Thanks! This is helping me greatly with my earth science assignment

"Chinese" Wind Farm in Texas: Green Jobs FAIL?

This $1.5 billion wind farm -- a US-China joint venture paid for in part by Chinese banks -- will be built not with turbines from usual suspects GE or Vestas, but with Chinese-made machines from a year-old company called A-Power.

Needless to say, most of the project's green jobs will be created in China. And don't shoot the messenger, but it's hoping to secure 30 percent, or $450 million, of its financing from, yes, U.S. stimulus funds.

Green energy not so friendly

The answer's not blowing in the wind

By Paul Mulshine/The Star Ledger 2/12/12

“People says the sound is like sneakers in the dryer or a threshing plant or a jet that never lands,” she said. “If you close the windows and doors to keep out the noise, things are still going to vibrate.”

The tips of the turbine blades can reach speeds of 150 mph, killing lots of migrating birds. Meanwhile the air-compression effect makes bats’ lungs explode

@RandomVersion you talking bullshit, get a grip and go study about windpower weirdo!

bro thanks u just did my project thanks

Could the Wind Turbines of Chile Harm Blue Whales?

Time AARON NELSEN

Wind turbines are increasingly recognized as a lethal hazard for birds, but some scientists now think they're also harmful to marine life. From half a mile away, the whooshing turbines emit an acceptable noise level of around 50 decibels; but if some of the Ecopower turbines are placed as close as 10 meters from the shoreline, they say, levels for ocean life could approach if not exceed a more harmful 100 decibels.

@RandomVersion am i pretty? :$

I saw this in class... When I first heard the man i wanted to know IS THE NARRATOR JOHN BARROWMAN

[aacowboy12]

heppolt wind turbine is a better idea this way heppolt speets up the wind speet its easer to toand it will kill no birts and chek heppolt wind turbins on the trailer

WORLD RECORD: BIGGEST WIND TURBINE

Visit: windturbinecarriedbywheels.wee­bly.com

ZERO-NOISE from gears and generators since they are sealed underground.

SAVES THE BIRDS AND BATS since slow-moving.

DOES NOT NEED TO OCCUPY A WIDER LANDSCAPE since the turbine can be very tall.

MAY BE LOWER-COST since it may use timber and other cheaper things.

ELUDES HURRICANE FORCE since the blades automatically close.

NO FIRE since well-cooled.

HELPS THE WIND ENERGY COMPANIES since it is FREE FOR ALL.

man u suck it was soooo boring gooo pollution!

Narrator says: rotates at 18 rpm and "that's not nearly fast enough to generate electricity" Perhaps the government should tell Enercon, Northern Power and GE about this. They all make large wind turbines that have no gearbox. The fact is you can build a wind turbine with a low torque, high speed generator, or a high torque, low speed generator, both are commercially viable with the latter gaining on the former.

duuude

[v1Sara417]

LOL.

[catothewiser]

@lukeseti - why do you say "directly" - trying to create a straw-man? Solar energy was converted to chemical energy by plants and became part of the biomass that became oil. Unless you believe oil's source is abiotic in whole or in part, the biomass source is 100% from he sun.

[Megafanman703]

I can't stop watching this!!!

[catothewiser]

I prefer solar energy. The energy gathered naturally and concentrated for thousands of years - it is called "oil."

[casey360360]

@catothewiser rofl you sir, are ignorant.

[catothewiser]

@casey360360 - oh, how so? See reply below.

[MsMusicgirl209]

@catothewiser

Solar energy is from the sun. Oil is a fossil fuel. Don't mix up the two.

[catothewiser]

@MsMusicgirl209 - the source was still the sun.

[catothewiser]

There isn't that much energy in wind and what there is is not all captured. How much energy does it take to MAKE one of these turbines? What is the break even point? What is the lifespan and maintenance? 9,000 homes when the wind blows? LOL! Not impressed.

[morpher34]

This is a very good video. School appropriate, and students can watch it at home for homework if they want to. Good job, Energy 101.

[rw5791]

obama green energy scam artists are taking a wrecking ball to america's economy.

[NateTheGreat25]

@rw5791 lol bro, i think you read too much stuff and dont know enough REAL information or how much of anybody's is getting spent on anything. i recommend you stop reading the TABLOIDS lol

[Pillowpants8495]

@rw5791 Green energy is fantastic for the economy. You've been mislead.

[rw5791]

@Pillowpants8495 it's a main reason why obama has fucked up the economy so badly.Second only to obamacare.

[Pillowpants8495]

@rw5791 The economy was fucked before Obama was elected. Granted he hasn't been able to fix the economy. I didn't vote for him and I won't vote for him in 2012 either but your ignorance needs to be called out. Wind can create more jobs per dollar than any other type of energy. Energy efficiency, I.E. making better windows, insulation, cars, etc. is both profitable and creates many jobs.

[rw5791]

@Pillowpants8495 u sucked obama's ass in'08 and you'll do it again in '12,and u know it.So lets stop the bullshit.

People are suffering out here and we're tired of your excuses for the marxist obama.When we don't perform in our jobs we get fired in a second and that's what will happen to obama next year.The american people will fire his black ass.

America runs on oil and we all need to get back to work.

[centurys822]

Where can I see subtitles for this video?

[NateTheGreat25]

Wind is America's natural resource. It's a safe and clean renewable energy source that's made in the USA. Using the power of wind means a better life for Americans. Invest in America's future, support American Wind today. Email me at texasboi25@yahoo.com for more info. If you have a fundraising network we can help as well.

[rw5791]

@NateTheGreat25 a wind farm is like a bird aushwitz?

[NateTheGreat25]

@rw5791 huh?

[rw5791]

@NateTheGreat25 duh....oh?

[NateTheGreat25]

@rw5791 first off you should spell the city right its auschwitz. second you should make more sense in your terminology of words. bird aushwitz? third, i didnt say duh, i said huh as in what do you mean?

[rw5791]

@NateTheGreat25 It would be safer for the birds if we all just strapped propeller beanies to our ass's and farted.Are u financially invested in this scam?Maybe you've got a little of that solyndra-obama action goin' on.

[NateTheGreat25]

@rw5791 I think I have type-invested too much time into talking with you. Maybe you should invest some time typing somewhere else. Can't even keep it professional and type without swearing.

at least my tax dollars are being put to good use in some areas

nice video

this will be good for my progeck
