Wind Energy is Growing Fast

Wind is the fastest growing energy source in the world. Here in the US wind farms have popped up in more than 30 states, producing enough energy to power an estimated 2.5 million homes a day. Thanks to growing concerns over natural gas prices, a desire for energy independence and incentives for renewable energy production, it's expected this trend will continue.

... And in Denmark, wind energy supplies 20 % of that nations total electricity demand! - GO DENMARK!!! :D :D :D

[HeroDanny]

Denmark is an inspiration to us all!

when i heard 6% by 2020 i almost cried...

that number should be a lot bigger

i was thinking 20% by 2015

:(

it's a sad sad day,

but there is hope!

great video!

I don't understand why wind turbines don't have the blades on both sides. Wouldn't that be twice the energy?

The worlds largest market for renewables today is Germany, and the Germans have just decided to become 100% self-sufficient with renewables by 2050.

Latest studies have shown that it is possible.

@scbrah That is a ridiculous statement and it was also used for those plants that were built in the past to make nuclear power more palatable. It wasn't true then and it will not hold true in the future. It is based on man being inherently honest, but that fallacy is of epidemic proportions. Lobbying (bribing) Congress and the safety departments by greedy companies will always be a factor.

Of the 440+ reactors, 90 are in seismically unstable areas. 23 MOX reactors in America alone on faultlines

@scbrah I would be interested in seeing your statistics, can you please send me a link. My notes state that the USA produces 41 GW of air energy per year (3rd in the world - even above Denmark and Spain which have a huge national wind energy production - Denmark at 20%) - California produces the 3rd most in the US at 3 GW. Please send your sources.

@scbrah Yes, I am fully aware of what biodiversity means. It is, according to the Websters Dictionary - "Diversity among and withinplant and animal species in an environment - key word here "environment" - not world. And no, it has nothing to do with a species being extinc - if a hgabitat cannot support a species, the the species will either emigrate or die off in the area. The does not mean that a species will die off all over the world which is what "extinct" assumes.

@9914tricky Benthic sediment buildup will only cause ecological damage in front of the dam. And "reduces aquatic biodiversity"? are you suggesting that animals will go extinct because of sediment buildup in front of 1 dam? or do you just not know what "biodiversity" means? and also there are alternative options that the chinese government could take to support shangahis sedimentary plain. i.e. artificial sediment, rip rap etc...

[scbrah]

@9914tricky no. the statistic is based on overall "clean"energy, biodeisel and fossil fuels not included

[9914tricky]

@scbrah (part 3, dam) The city of Shanghai, more than 1,000 miles (1,600 km) away, rests on a massive sedimentary plain. The "arriving silt strengthens the bed on which Shanghai is built... the less the tonnage of arriving sediment the more vulnerable is this biggest of Chinese cities to inundation...

Benthic sediment buildup causes biological damage and reduces aquatic biodiversity.

[9914tricky]

@scbrah (part 2 to post on dam) Because the flow is slower above the dam, much of this sediment will now settle there instead of flowing downstream, and there will be less sediment downstream.The absence of silt downstream has three effects: Some hydrologists expect downstream riverbanks to become more vulnerable to flooding.
