The local communities will benefit to some degree from these wind farms, however, the benefit is not huge. The construction phase is performed by contractors from outside the local areas. These contractors will stay locally so B&Bs etc will benefit during the construction phase.
Once the wind farms are established, there is only the maintenance work, which is also performed by contractors, again not local. The maintenance work is not ongoing, it is not only seasonal work, but carried out over a very short period.
The other way that the local communities benefit is through a fund that the wind farm operators set up. Some see these ‘funds’ as a bribe, others as a way to help the local communities. The funds however, are not huge amounts of money.
Although the turbines have a life span of 30yrs, the concrete bases and access roads are permanent structures. So, it is fairly obvious that these locations will be used again with new turbines.
There are also larger turbines being used now, so it is also quite possible that the replacements could be larger and visible from a greater distance.
