Ecotricity - Bristol Port - Wind Turbine Construction Video

Back


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 13,000 tonnes of carbon emissions every year for the next 30 years!

Noone is saying that wind turbines are the answer. It's just part of the answer. I also admit that there are problems with it like 'scudlington' said. In fact the turbines actually use a small amount of energy when there isn't any wind. However wind turbines recover the energy used to manufacture, install, and run them after only 4 or 5 months. Coal plants never achieve this. So, WTs have flaws but they are greatly overshadowed by the benefits of putting them up.

"However wind turbines recover the energy used to manufacture, install, and run them after only 4 or 5 months."

Who cares?

A significant fraction is simply flushed down the toilet(offpeak, coal plants don't shut down) or eaten up by spinning reserve. For each kWh of wind power you need 1-2 kWh of natural gas; NG is expensive and difficult to transport.

The grid is not a "bank", hell, it's not even a connected graph. Transmission, not generation, is the hard part and wind makes it much worse.

Excellent! I look forward to it.

Scudlington - your lenses seem to be peculiarly tinted ;-)

I will respond in detail later - but for now I have removed all comments with profanity - so that minors and corporate users can view the page/video....

Jeskao I have to say that you are right. It is 'just a sign' some would even say symbolic. National grids, all essentially work to the same principal of balance...demand/supply. These 'green' techs do not and cannot address this issue because they have no control over the power source. The largest of WTs will supply less power than the battery in my watch when the wind isn't blowing and therefore must be backed up at all times. You must think about these issues minus green tinted lenses.

this is one sign of how amazing the world is going to coming together to bring new energy resources in to power lines, to help off set our carbon output. Just as much fuel is used to bring all that smelly coal with it needs to go to produce power, stop thinking so far inside the box, invest in something that will last for longer than the short sighted foreseeable future we all like to live in

Just one more thing before I get off me soap box. I'm not 'anti environment' or do I like to be labelled a 'denier' (as if we were somehow back in the days of the Spanish inquisition.) Nothing depresses me more than the destruction of our natural habitat, (particularly the great rainforests) but if you really believe that building windmills will somehow help the polar bears or prevent New York being 20ft under then you really are living in cloud cuckoo land.

(Renewables obligation). This states that each provider must generate a certain percentage of their electricity mainly by the above means. They can't, because even though we are now in charge of the weather we still can't make the wind blow when we need it, consequently they are fined (taxed) and dutifully pass this on in full to us mugs...marvellous. This is all now set to get far worse. A couple of months ago Gordo triumphantly announced that he was going to save the world by spending...

...sorry to go on...because the 'consensus' is that everyone agrees that we are now somehow in charge of the worlds weather. Clearly bananas but to governments and certain sectors of private enterprise a money making opportunity made in heaven. That old chestnut 'they'll tax us for the air we breathe' is already with us. My families last electricity bill was 30% higher than it should have been. 30% on top of excessive profiteering on a necessity by a nifty little EU directive called the RO

The interesting thing is that our government knows this but because the debate about 'climate change' is now apparently over, our great Scottish leader and his henchmen now feel they have a vote winning opportunity to commit the country to what will eventually prove to be a catastrophically expensive act of vandalism to our beautiful countryside. Most do not realise that this is one of the main factors behind our ever increasing energy bills. It is never reported by the BBC or seldomly discussed
