BT is to implement a wind-farm project that it hopes will supply a quarter of its electricity by 2016, the telco revealed on Thursday.
The telecoms company says the project could cost up to £250m.
BT claims it is responsible for 0.7 percent of the UK's electricity consumption. It already has the country's largest green-electricity contract with npower and British Gas Business.
BT is aiming for an 80 percent reduction in its carbon emissions within the next nine years — a sizeable task given that it has already been responsible for 640,000 tons of CO2 this year alone. Nonetheless, it claims to have already reduced its CO2 emissions by 60 percent since 1996.
"There is a pressing need for industry to cut carbon in ways that make business sense," said the group's finance director, Hanif Lalani. Lalani suggested that wind energy would "play an important part" in achieving BT's CO2 reduction goals, but also praised broadband technology for its role in cutting the need to travel, through home working and videoconferencing.
According to BT, the wind farms could, by 2016, generate enough electricity to power a city the size of Coventry, which would be about 250MW in total.
It is currently looking at suitable sites, but has already applied for planning permission for test masts at Goonhilly Satellite Earth Station in Cornwall, Wideford Hill Radio Station in the Orkney Islands and Scousburgh Radio Station in Shetland.
Wind turbines have faced considerable resistance from campaigners, many of whom see the masts as a blight on the landscape.
Nevertheless, BT claimed in a statement that it is "committed to working responsibly with local communities" and that it will "ensure that they are engaged throughout the development process".
John Hutton MP, the secretary of state for business, enterprise and regulatory reform, said on Thursday that BT's move was "a great example of how businesses can contribute and help us meet our ambitious target to dramatically increase the amount of energy we get from renewable sources".
BT possesses considerable data-centre capacity, which creates much of its CO2 emissions.

Feature: Making your data centre greener
Aside from buying into the numerous green intiatives launched by hardware makers, there are other ways to reduce the environmental impact of your IT systems...
Data released by Gartner, the analyst firm, has suggested that data centres are responsible for almost a quarter of the CO2 emissions from the information and communications technology industry. PCs and monitors account for 40 percent of the total.
Many other technology suppliers, including Intel, Sun and IBM, are also trying to improve the efficiency of their energy use within the data centre and their wider corporate infrastructure.
Talkback
So we can expect BT service to get worse then. Wind power has been shown to be both unreliable at best and more expensive when subsidies are factored in. California once had a 'wind only' policy but had to abandon it due to extreme power-cuts that were unacceptable. The best we can do in the UK is less than 25% of the installed capacity - and that depends on the wind blowing!
There must be a better way that is more reliable. Do I hear someone saying nuclear? At least that is reliable and the problem of waste can be managed by using 2 different types of reactors. One uses the waste from the other as part of its fuel.
