Small rural communities could afford to put up a windmill for their own use irrespective of being connected to the grid. One often sees small communities here with a water tower to provide water pressure. A single large windmill is roughly equivalent to a water tower and should be a familiar sight in all small communities.
That isn't to say that they be disconnected from the grid but instead be an addition to the electricity provided by the grid. However this would be exclusively that one small town's electricity generator. They would always have basic and emergency services power during major black outs or brown outs. They would probably be able to sell back excess electricity to the grid depending on size or how many windmills are erected.
Every small town and hamlet should have at least one emergency services windmill. That said... every small town should invest in providing their own electricity. That was never possible before but it is now.
Local energy production is possible and well within the pocketbooks of small communities using windmills.
In remote rural communities such as Mr. Alegado mentions, it is almost a requisite. The costs of electricity would eventually pay off the cost of a windmill and then the costs of electricity could be reinvested back into that hamlet or town instead of that money going to the big energy producers.
Technology has caught up to locally produced power for remote communities. Somehow our minds have grown so used to thinking that electricity must be produced on a huge scale...that we forget that small communities don't need a huge scale and the technology is now available for them to do their own energy production.
They should do their own thing ... so to speak! Geez I haven't said that in a long time... lol!!!
Do your own thing... energy production wise! Get your town their own windmill.
