 COMMUNITIES will be offered council tax discounts or cheaper electricity in return for accepting wind farms under government plans to increase significantly their number in Britain.  Charles Hendry, the energy minister, will announce a new approach today to try to encourage residents to voluntarily accept wind farms, rather than "hectoring" them into submission.  Under the plans, business rates paid by owners of wind farms would be chanelled back into the community rather than going to the Treasury.  The money could be used to reduce council tax bills or to invest in local services. Communities could also buy their own wind turbines to run for a profit.  Thousands of turbines will need to be built across the countryside over the next 10 years in order to meet strict climate change targets on renewable energy. However, many of the best sites for onshore wind farms are in areas of natural beauty and their development has in many cases been fiercely opposed by communities.  Mr Hendry said the Labour government's approach of "hectoring" people into accepting wind farms - for example by comparing opponents of the turbines to those who once opposed seat belts - had not worked.  Instead, he believes the Coalition should encourage communities to accept wind farms by ensuring that they brought financial benefits to the area.  Campaign groups said it was naive to expect communities to give up their opposition to the "inefficient technology" simply for the sake of a "bribe".  In the past, the Tories have sided with those who oppose wind farms because of the visual impact of the 300ft turbines on the countryside. Mr Hendry insisted the new approach would ensure
