Ecotricity - Bristol Port - Wind Turbine Construction Video
Posted by admin on Mar-10-2010
Just launched! Watch our stunning new time-lapse video of the construction of 3 wind turbines at Bristol Port. The turbines will produce over 15 million units of new green electricity annually, enough to save around 13000 tonnes of carbon emissions every year for the next 30 years! www.ecotricity.co.uk

So to put it another way, you’d need to erect 450,000 of these turbines each year just to counteract the annual growth in CO2 emissions. That’s 1200 per day.
This is neither physically possible nor economically viable.
Total energy per yr = 6MW x 20% avg output x 365 days x 24 hrs = 10512 MWhrs
CO2 saving = 10,512 MWHr x 0.7 tons of CO2 / MWHr for coal = 6400 tons of CO2.
Note: This only translates into a real saving if the standby backup generation is CO2 free (eg. hydroelectric or nuclear)
Total global est man-made CO2 emissions = 3×10^10 tons / yr. The UK emits 2% of this.
So these 3 turbines will save 0.001% of UK & 0.00002% of global emissions which are growing at 3% / yr as China & India grow
Just to clarify: These turbines produce 2MW each when the wind is blowing at optimum speed. However average output over the year is only 20% due to wind speed variation. At times the output will fall to zero when the wind is too weak or too strong. So standby conventional generation is needed for these periods greatly increasing the cost and reducing CO2 savings.
Look at “Rare Earth Mineral Mining in China” on Youtube
what song is this
Look , if you guys think wind power sucks like hell, there’s other thing like water power or geometrical power. Anyway this renewable energies saves tons of money. So either say shit about this wind power and protest outside the government buildings of US while getting a high bill OR let Earth live longer and get CHEAPER bills. But GREAT VIDEO!
Wind energy. If we took 1 tillion dollars the cost of the wars in you know where. 1 trillion/4 million (estimated cost of scale for a commercial one wind turbine) would net 25 billion wind turbines. One wind turbine can generate 2.5MWh electricity. 2.5MWh can power 350 homes in a northern cold state. 25 billion X 250 homes? I think that pretty much covers the US needs for power. Just having fun here, don’t shoot the messenger.
design and build for increased energy efficiency
Immigration? Dude if you aren’t an American Indian, you are an immigrant or a descendant thereof. If it wasn’t for immigration, there wouldn’t be a United States, Merry Christmas.
wow there are some weird oppinions here…..
anti wind energy? wtf?
I think the best way to reduce carbon emissions in the west is to have an immigration moratorium. Statistics clearlyu show the USA population grew by 100 million in the last 40 years and nearly all the growth was due to immigration.
The west could drasically reduce carbon emissions with a reduction in immigration and population and would have nearly stable growth in the USA with a moratorium on immigration.
u obviously know nothing about wind energy huh. the ones i just finished building were Vestas 3.5MW in Iowa. 62 of them can power about 50,000 homes and are expected to last 20-30 years.
This is just a hippy dream. The only serious energy is from coal and oil. It is harsh, I know.
The wind energy is not viable.
I think what they mean is all 3 units combined produce 15 million kilowatt hours….
the subsidies for coal and nuclear are much geater than for the wind industry.
Totally awesome, if I get burnt out from IT, im going into wind industry. Its fascinated me for years
at :52 ” over 15 million units of green electricity - enough to run over 4600 homes a year” wtf?
Do they mean over 4600 UNITS enough to run 15million homes? hope so or thats just nuts.
incredible.
Enercon shit…
What are you paying in hidden taxes for them?
yes. I finished long ago.
Where can I get Verticial Wind Turbines in Australia? and How much do they cost eg $5000 for a 2kW? I wonna least cut back my Power Bill by 80% or even more if possible =)
Wasn’t sure if you had finished
Eco’…You didn’t get back to me…
excellent work!
