British Power is all Wind.

Despite the opening of the new Thanet wind-farm in the English Channel, the present rate of development of wind-power indicates that Britain will struggle to meet its target of providing 15% of its total energy from renewables by 2020.

Not everyone is convinced that wind-power is the most reliant route to clean, renewable carbon-free energy, and it is concerning that Britain is relying on a power source that must be backed up by more constant technologies such as nuclear, coal, or gas, because the wind blows inconsistently, as is its nature. A mere 2% of Britain's electricity was produced from renewable sources in 2002, but it is hoped that this should rise to 10% by the end of the year in light of the new wind-power generating capacity.There are further cost issues in upgrading the national grid to cope with power-surges and the need to switch between different power sources.
It should be noted that electricity provides only around one third of the total energy used in the U.K, and the bulk of that is accounted for by heating and transportation, which is supplied by respectively coal/gas and oil based fuels. Hence the UK will have its work cut out if it is to meet a EU target to raise its overall energy provision from renewables from the present 5% to 15% by 2020.
The actualization of an overall wind-power strategy is not going smoothly, however, and the number of new wind-farms coming on-stream has fallen by 30%, in part as a consequence of the recession.
There has also been a fall in the past 12 months by 50% in planning approvals for wind-farms in England, a situation that is also reflected in Scotland. There is also considerable opposition to wind-turbines which are perceived as unsightly and noisy, as is reflected by the 230-odd campaign groups that operate across the whole of the U.K.
Indeed, some of these groups advocate nuclear power as a better option than wind, a situation that would have been almost unthinkable ten years ago. It was estimated in 2008 that to meet the U.K. wind-power goal by 2020 would require building one new turbine every day for the next twelve years. Since progress so far has fallen far short of this rate of conversion, little confidence is lent that the nation will be able to keep its promise on renewables.
