Background for non UK readers: BT (British Telecommmunications plc) is the UK’s main telco, providing comms services to nearly all ISPs in the UK apart from a handful of cable companies.
Renewable sources of energy include wind, wave and solar power, rather than using fossil fuels like oil or coal.
The power will be used in all of BT’s 6,500 phone exchanges, as well as its satellite relay stations and offices.
The plan comes after the government’s call for 10% of the UK’s energy to have come from non-polluting renewable sources by 2010, in an effort to halt global warming.
Burning fossil fuels such as oil and coal are blamed by some scientists as a major contributor to rising temperatures.
Wind-farms
BT’s contract will be the biggest in history by a British company, though other UK firms have already signed up to using environmentally-friendly energy.
The UK is legally bound, under the Kyoto Protocol on climate change, to reduce emissions of greenhouse gases by 5.2%, below 1990 levels, by 2012.
In his foreword to the 2003 energy white paper, Tony Blair stated: “We are showing leadership by putting the UK on a path to a 60% reduction in its carbon dioxide emissions by 2050.”
Two new wind farms which will generate enough power for 118,000 homes were given the go-ahead in Scotland last week.
Deputy Enterprise Minister Allan Wilson has announced turbines will be built at Braes of Doune, near Dunblane, and Farr, near Tomatin in the Highlands.
Story from BBC NEWS:
I think the reasons are as much financial and technical as altruistic – renewable power systems which depend on intermittent energy sources (sun/wind) work better if used with a large DC storage battery to store the power for later use.
Now there just happens to be a very large battery in every BT telephone exchange (some of them take up entire rooms the size of a tennis court) – and its just the correct voltage to be as efficient without danger of electric shock (-48V dc) – BT need the battery anyway as an integral part of how the telephone system works, most exchange buildings are large with lots of spare space nowadays – and the roof will be full of mobile phone repeaters, sat dishes etc so another mast makes no difference..
Its an excellent bit of good practice though, making use of both new and tried and tested technology. For once BT has done something right..
RUUUUUUUUUUUUUUUUUUUUUUUUUD BBBBBBBBBBBBBBBBBBBBBOOOOOOYS at BT, big yourselves up… that is the best bit of news ive had in ages. a proper large, high profile company leading the way in caring for the planet. i dont care if they can do it relatively cheap – they’ll set a standard, and open up a new selling point which other companies will be keen to gain too.
such a releif to see something positive about energy, after all the beefs oil’s kickin up and the nonsense people have been talking about nuclear again has been shitting me up. it will be interesting to see how it affects the economy, tho, in terms that its sooooo cheap to run a wind farm compared to an oil drill and refinery. my mate dave works on oil drilling, so he’ll be out of a job (not for a while yet, obviously) but potentially energy will be way cheaper, and our view of how we use energy will change. who cares if you waste electricity if it has no byproduct? dunno.
sustainable electrictity! think how sound that will be!
I hope they publish some of the techie stuff to the internet – lots of other companies could follow their lead.
All big office buildings have roof space where in particular solar panels could be deployed and small turbines will go un-noticed; the equipment comms rooms will run off the -48v DC power supply, the battery (which does not need to be big and bulky nowadays) can also be part of a UPS for servers for business critical kit if the mains power goes out!
what the company does not use, can be exported back to the electricity company and offset against energy costs
As for the oil rig workers, society should be re-training them for other engineering skills; renewable energy equipment still requires “heavy” engineering and construction skills to prepare the sites for it, install it and keep it running.
